REPORTING SAFETY DEFECTS  
REPORTING SAFETY DEFECTS  
If you believe that your vehicle has a defect that could cause a crash or could cause injury or  
death, you should immediately inform the National Highway Traffic Safety Administration  
(NHTSA) in addition to notifying Multiquip at 1-800-421-1244.  
If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety  
defect exists in a group of vehicles, it may order a recall and remedy campaign. However,  
NHTSA cannot become involved in individual problems between you, your dealer, or  
Multiquip.  
To contact NHTSA, you may either call the Vehicle Safety Hotline toll-free at 1-888-327-4236

GENERAL INFORMATION

wellpoint applications.  
rubber valve seat, self-aligning rubber hinge. This design  
increases reliability.The backflush valve allows for cleaning  
of the suction strainer or wellpoint headswhile the engine is  
running.  
The Dry Prime pump uses a vacuum pump to remove the  
air. This becomes important in certain applications such as  
long suction hose runs or multiple suction points (such as  
wellpoints). In these cases, high volumes of air enters into  
the pump. Dry Prime uses direct-drive vacuum pump to  
efficiently remove very large volumes of air quickly to obtain  
the priming necessary for these special applications. Dry  
Prime is very useful when you have to move a lot of water  
fast.  
Fuel Tank Frame and Trackbar System  
Run time is up to 72 hours with the Dry Prime’s fuel tank,  
good for continuous running for those long-term jobs.There  
are two corner fuel drains to check condition of fuel. The  
TrackBar system allows for the easy addition of jack stands,  
fenders, axle, lifting bail, and other options. This allows for  
fast and easy positioning of the jack stands on the job site  
to fit the application, or to add subtract jack stands as  
required.The removable, retractable towing tongue minimizes  
storage requirements.  
Impeller  
The Dry Prime impeller has a patented design to eliminate  
cavitation. It is a 2-blade spiral, smooth flow, open, non-clog  
impeller, designed to handle up to 3.2-inch solids.The impeller

rubber hoses can easily fail at the end of  
the hose fittings. Leaks from the hoses  
can cause high-pressure liquid to be  
discharged, causing dangerous  
conditions. Make sure pressure rating of

6. Check that the discharge hose (Figure 6) is securely at-  
tachedand notrestricted.Placehosesothat it laysas straight  
as it is possible on the ground. Remove any twists or sharp  
bends from hose which may block the flow of water.  
7. Light discharge hose should be anchored to avoid move-  
ment with high flow or high pressure.  
Suction and Discharge Hoses  
Suction and discharge hoses are  
available from Multiquip. Contact your  
nearest dealer for more information.  
1. Check that the suction hose is securely attached to the  
pump. Make certain suction hose (Figure 3) does not have  
any air leakage. Tighten hose clamps and couplings as  
required.  
DANGER - Flammable Fluids  
2. Shorter suction lift and suction hose length will produce  
betterperformance.  
DO NOT pump flammable fluids, corrosive chemicals or fluids  
containing toxic substances. These fluids can create potentially  
dangerous health and environmental hazards. Contact local  
authorities for assistance.  
3. Make sure the suction strainer (Figure 6) is clean and  
securely attached to the water end of the suction hose.The  
strainerisdesignedtoprotectthepumpbypreventinglarge  
objects from being pulled into the pump. Failure to use a  
strainer could cause damage to the pump, impeller, pump  
shaft, pump bearings, or wear plate.  
8. Always use a suction hose or pipe that matches the size of  
the pump inlet to insure optimum performance and reduce  
the risk of damage to the pump.  
4. Ifastrainerbecomescloggedwithdebris,thestrainercanbe  
clearedwhilethepumpisrunningbyopeningthebackflush  
valve.  
9. It is recommended that the discharge hose or pipe match  
the size of the pump outlet to reduce friction as much as  
possible. Using a discharge line that is larger than the pump  
outlet will reduce friction and improve water flow.Similarly, a  
smaller line will reduce water flow by increasing friction.

To ensure longer pump life and service, please follow the  
pump maintenance guidelines as listed in Table 6 and on  
preceeding pages.  
To perform the pump vacuum test do the following:  
1. Perform all start-up steps without installing the hoses.  
2. Block the suction with a plug or heavy rubber flap as  
shown in Figure 12. An accurate vacuum gauge should  
be installed in the plug or flap to check vacuum system  
performance and pump vacuum gauge.  
Table 6. Pump Maintenance  
Check bearing housing.  
Check pump seal oil reservoir  
2. Start the engine and run at 1,800 RPM. Note the  
maximum vacuum reading.  
Check vacuum pump seal oil reservoir.  
Daily  
3. Shut off the engine and check the vacuum reading.The  
vacuum reading should be .75 to .9 Bar or 25 to 27  
inches. Vacuum reading should hold for about 3 to 10  
minutes before dropping to zero.If vacuum reading drops  
fast, check for leaks and repair if necessary. Listen for  
leaks. If area is quiet, small air leaks should be easy to  
hear.  
Check water level in vacuum system and anti-freeze  
concentration for weather conditions.  
Check for leaks and kinks in discharge hose.  
Check if water is clean and anti-freeze is right for  
conditions in vacuum system.

MAINTENANCE (TRAILER)  
The following trailer maintenance guidelines are intended to  
assist the operator in preventative maintenance.  
You must check the fluid level in the master cylinder  
reservoir at least every three months. If you tow your trailer  
an average of 1,000 miles per month in a hot and dry  
environment, you must check the brake fluid level once a  
month. The brake fluid reservoir is located on the tongue of  
the trailer. Always fill with clean, uncontaminated DOT 4  
brake fluid.  
Trailer Brakes  
Properly functioning brake shoes and drums are essential to  
ensure safety. The brakes should be inspected the first 200  
miles of operation. This will allow the brake shoes and drums  
to seat properly. After the first 200 mile interval, inspect the  
brakes every 3,000 miles. If driving over rough terrain, in-  
spect the brakes more frequently.  
Figure 19 below displays the major air/surge brake compo-  
nents that will require inspection and maintenance. Please  
inspect these components as required using steps 1 through  
6 as referenced in the “Manually Adjusting The Brakes” sec-  
tion on this page. See Table 11 Surge Brake Troubleshoot-  
ing.  
Surge Brakes  
If your trailer has surge-operated brakes, they  
function the same way the surge brakes do on your tow  
vehicle. The surge braking system must be inspected at  
least as often as the brakes on the tow vehicle, but no less  
than once per year. This inspection includes an  
assessment of the condition and proper operation of the wheel  
cylinders, brake shoes, brake drums and hubs.  
Manually Adjusting the Brakes  
Most axles are fitted with a brake mechanism that will  
adjust the brakes during a hard stop. However, some  
braking systems are not automatically adjusted by hard  
stopping. These brakes require manual adjustment. The  
following steps apply to adjust most manually adjustable  
brakes.  
1. Jack up the trailer and secure it on adequate capacity  
jack stands.  
2. Be sure the wheel and brake drum rotate freely.  
3. Remove the adjusting-hole cover from the adjusting slot  
on the bottom of the brake backing plate.  
4. With a screwdriver or standard adjusting tool, rotate the  
starwheel of the adjuster assembly to expand the brake  
shoes. Adjust the brake shoes out until the pressure of  
the linings against the drum makes the wheel very  
difficult to turn. Note: Your trailer maybe equipped with  
drop spindle axles. See axle manual for your axle type.  
You will need a modified adjusting tool for adjusting the  
brakes in these axles. With drop spindle axles, a  
modified adjusting tool with about an 80 degree angle  
should be used.  
Figure 19. Surge Brake Components  
Electric Brakes  
Electrically actuated brakes (Figure 20) are similar to  
surge brakes. The basic difference is that surge brakes are  
actuated by an electromagnet. Listed below are some of  
the advantages that electric brakes have over  
surge brakes:  
Brake system can be manually adjusted to provide the  
corrected braking capability for varying road and load  
conditions.  
Brake system can be modulated to provide more or  
less braking force, thus easing the brake load on the  
towing  
vehicle.  
Brake system has very little lag time between the time  
the vehicle’s brakes are actuated and the trailer’s brakes  
are actuated.  
5. Rotate the starwheel in the opposite direction until the  
wheel turns freely with a slight drag.  
6. Replace the adjusting-hole cover.  
7. Repeat the above procedure on all brakes.  
8. Lower the trailer to the ground.  
Brake system can provide an independent emergency  
brake system.

MAINTENANCE (TRAILER)  
Remember in order to properly synchronize the tow vehicle’s  
braking to the trailer’s braking, can only be accomplished by  
road testing. Brake lockup, grabbiness or harshness is due  
to lack of synchronization between the tow vehicle and the  
trailer being towed or under-adjusted brakes.  
WARNING - Breakaway Brake System  
If electric breakaway brakes do not operate when trailer is uncoupled  
from the tow vehicle, death or serious injury can occur.  
Check emergency breakaway brake system BEFORE each tow.  
Before any brake synchronizations adjustments can be  
made, the trailer brakes should be burnished-in by applying  
the brakes 20-30 times with approximately a 20 m.p.h. de-  
crease in speed, e.g. 40 m.p.h. to 20 m.p.h. Allow ample  
time for brakes to cool between application. This allows the  
brake shoes to slightly be seated into the brake drum sur-  
face.  
Figure 20 displays the major electric brake components that  
will require inspection and maintenance. Please inspect  
these components as required. SeeTable 12 Electric Brake  
Troubleshooting.  
The electric brakes that operate in  
conjunction with the tow vehicle  
brakes must be “synchronized”  
so that braking is properly distrib-  
uted to the tow vehicle brakes and  
the trailer brakes. For proper op-  
eration and synchronization, read  
and follow the axle/brake and the brake controller  
manufacturers’ instructions. To make certain an electrically-  
operatedbraking system will function properly, you must have  
your dealer inspect the magnets at least once a year, or  
each 12,000 miles. See the brake manual for wear and cur-  
rent inspection instructions.  
Hydraulic Brack Actuator  
The the surge brake actuator (Figure 21) is the mechanism  
that activates the trailer’s brake system. This actuator  
changes fluid power into mechanical power. Therefore, the  
fluid level must be checked frequently to assure that the  
brakes function properly.  
Figure 20. Electrical Brake Components  
HYDRAULIC  
BRAKE FLUID  
RESERVOIR  
Breakaway Battery  
This battery supplies the power to operate the trailer brakes  
if the trailer uncouples from the tow vehicle. Be sure to  
check, maintain and replace the battery according to the  
battery manufacturer’ instructions.  
Breakaway Switch  
This switch causes the breakaway battery to operate the  
electric brakes if the trailer uncouples from the tow vehicle.  
The pull cable for the pull pin is connected to the tow  
vehicle, and the switch is connected to the trailer. To check  
for proper functioning of the switch, battery and brakes, you  
must pull the pin from the switch and confirm that the brakes  
apply to each wheel. You can do this by trying to pull the  
trailer with the tow vehicle, after pulling the pin. The trailer  
brakes may not lock, but you will notice that a greater force  
is needed to pull the trailer.  
Figure 21. Trailer Actuator  
WARNING - Actuator Fluid Level  
Failure to maintain proper fluid level in the actuator may  
result in loss of braking action which could cause severe  
property damage, injury or death.  
PAGE 32 —DRY PRIME PUMP — OPERATION MANUAL — REV. #3 (10/06/08)  
Download from Www.Somanuals.com. All Manuals Search And Download.  
MAINTENANCE (TRAILER)  
Periodically check the actuator mounting fasteners for  
damage or loosening. Inspect the actuator for worn or dam-  
aged parts. As you are towing your trailer, be aware of any  
changes in braking quality. This could be an early warning of  
brake or actuator malfunction and requires immediate  
attention. Consult a certified brake specialist to make  
necessary adjustment or repairs.  
DANGER - Wheel Bearings  
If trailer wheels are under water for a long period of time,  
wheel bearings may fail. If this is the case, service wheel  
bearings immediately.  
The possibility exists of the wheels falling off, causing  
equipment damage and severe bodily harm even death!  
Replace bearings that have flat spots on rollers, broken  
roller cages, rust or pitting. Always replace bearings  
and cups in sets. The inner and outer bearings are to be  
replaced at the same time.  
Adjustable Channel  
Your trailer may be equipped with an adjustable channel (Fig-  
ure 22) that allows the coupler to be raise or lowered to a  
desired height.Periodically check the channel bolts for dam-  
age or loosening.  
Replace seals that have nicks, tears or wear.  
Lubricate the bearings with a high quality EP-2  
automotive wheel bearing grease.

bearings for free running and adjust.  
Wheeel bearings (Figure 23) must beinspected and lubri-  
cated once a year or 12,000 miles toinsure safe operation of  
your trailer.  
If a trailer wheel bearing is immersed in water, it must be  
replaced.  
Turn the hub slowly, by hand, while tightening the spindle  
nut, until you can no longer turn the hub by hand.  
Loosen the spindle nut just until you are able to turn it  
(the spindle nut) by hand. Do not turn the hub while the  
spindle nut is loose.  
If the pump/trailer has not been used for an extended amount  
of time, have the bearings inspected and packed more  
frequently, at least every six months and prior to use.  
Follow the steps below to disassemble and service the  
wheel bearings.  
Install a new cotter pin through the spindle nut and axle.  
Check the adjustments. Both the hub and the spindle  
nut should be able to move freely (the spindle nut  
motion will be limited by the cotter pin).  
After removing the dust cap, cotter pin, spindle nut  
and spindle washer, remove the hub and drum to  
inspect the bearings for wear and damage.

should be inspected annually for signs of wear or  
deformations.  
Danger - Worn or Defective Suspension  
Worn or broken suspension parts can cause loss of  
control, damage to equipment and severe bodily injury  
even death!  
Check suspension regularly.  
WARNING - Cracked or BrokenWelds  
Improper weld repair will lead to early failure of the trailer  
structure and can cause serious injury or death.  
DO NOT repair cracked or broken welds unless you have  
a certified welder perform the repair. If not, have the  
welds repaired by your dealer.  
Danger - TrailerWelds  
Broken or damaged welds can cause injury or severe  
damage to your trailer and contents. Inspect all of the  
welds for cracks or failure at least twice a year.

TRAILER SAFETY GUIDELINES  
ALWAYS use lower gears for climbing and descending  
TRAILER SAFETY INFORMATION  
grades.  
Safety precautions should be followed at all times when  
operating this equipment. Failure to read, understand and  
follow the Operating Instructions could result in injury to  
yourself and others. Loss of control of the trailer or tow ve-  
hicle can result in death or serious injury.  
DO NOT ride the brakes while descending grades, they  
may get so hot that they stop working. Then you will  
potentially have a runaway tow vehicle and trailer.  
To conserve fuel, don’t use full throttle to climb a hill.  
instead, build speed on the approach.  
Common Causes for Loss of Trailer  
Slow down for bumps in the road. Take your foot off the  
brake when crossing the bump.  
Driving too fast for the conditions (maximum speed  
when towing a trailer is 60 m.p.h.).  
DO NOT brake while in a curve unless absolutely necessary.  
Instead, slow down before you enter the curve  
and power through the curve. This way, the towing vehicle  
remains in charge.  
Overloading the trailer or loading the trailer unevenly  
Trailer improperly coupled to the hitch  
No braking on trailer  
DO NOT apply the brakes to correct extreme trailer swaying.  
Continued pulling of the trailer, and even slight  
acceleration, will provide a stabilizing force.  
Not maintaining proper tire pressure  
Not keeping lug nuts tight  
Anticipate the trailer “swaying. Swaying is the trailer  
reaction to the air pressure wave caused by passing  
trucks and busses. Continued pulling of the trailer  
provides a stabilizing force to correct swaying. DO NOT  
apply the brakes to correct trailer swaying.  
Not properly maintaining the trailer structure.  
Trailer Towing Guidelines  
Recheck the load tiedowns to make sure the load will  
not shift during towing.  
Use lower gear when driving down steep or long grades.  
Use the engine and transmission as a brake. Do not  
ride the brakes, as they can overheat and become  
ineffective.  
Before towing, check coupling, safety chain, safety  
brake, tires, wheels and lights.  
Check the lug nuts or bolts for tightness.  
Be aware of your trailer height, especially when  
approaching roofed areas and around trees.  
Check coupler tightness after towing 50 miles  
.
Adjust the brake controller to engage the trailer brakes  
before the tow vehicle brakes. Your dealer can assist  
you by making this adjustment.  
Make regular stops, about once each hour. Confirm that:  
A. Coupler is secure to the hitch and is locked.  
B. Electrical connectors are made.  
Use your mirrors to verify that you have room to change  
lanes or pull into traffic.  
C. There is appropriate slack in the safety chains.  
Use your turn signals well in advance. Allow plenty of  
stopping space for your trailer and tow vehicle.  
D. There is appropriate slack in the breakaway  
switch pullpin cable.  
Allow plenty of stopping space for your trailer and tow  
vehicle.  
E. Tires are not visibly low on pressure  
DO NOT drive so fast that the trailer begins to sway due  
to speed.  
WARNING - Drive Safely  
Driving too fast for severe road conditions can  
result in loss of control and cause death or serious  
injury.  
Allow plenty of room for passing. A rule of thumb is that  
the passing distance with a trailer is 4 times the passing  
distance without the trailer.  
Decrease your speed as road, weather and lighting  
conditions deteriorate.  
Shift your automatic transmission into a lower gear for  
city driving.  
ALWAYS check for local trailer-tow speed limits in  
your area.

TRAILER SAFETY GUIDELINES  
CAUTION - LcalTowing Regulations  
WARNING - Coupler Selection/Condition  
Check with your county or state safety towing  
regulations department before towing your pump.  
Proper selection and condition of the coupler and hitch  
are essential to safely towing your trailer. A loss of  
coupling may result in death or serious injury.  
Be sure the hitch load rating is equal to or greater  
than the load rating of the coupler  
Driving Conditions  
Be sure the hitch size matches the coupler size  
When towing a trailer, you will have decreased acceleration,  
increased stopping distance, and increased turning radius  
(which means you must make wider turns to keep from hit-  
ting curbs, vehicles, and anything else that is on the inside  
corner). In addition, you will need a longer distance to pass,  
due to slower acceleration and increased length.  
Observe the hitch for wear, corrosion and cracks  
before coupling. Replace worn, corroded or cracked  
hitch components before coupling the trailer to the  
tow vehicle  
Be sure the hitch components are tight before coupling  
the trailer to the tow vehicle.  
Be alert for slippery conditions. You are more likely to be  
affected by slippery road surfaces when driving a tow  
vehicle with a trailer, than driving a tow vehicle without a  
trailer.  
WARNING - Coupler Connection  
An improperly coupled trailer can result in death or serious  
injury.  
Check rearview mirrors frequently to observe the trailer  
and traffic.  
NEVER drive faster than what is safe.  
DO NOT move the trailer until:  
The coupler is secured and locked to hitch  
The safety chains are secured to the tow vehicle  
The trailer jack(s) are fully retracted  
WARNING - Transporting Personnel  
DO NOT tow the trailer on the road until:  
DO NOT transport people on the trailer. The transport of  
people puts their lives at risk and may be illegal.  
Tires and wheels are checked  
The trailer brakes are checked  
The breakaway switch is connected to the tow vehicle  
The load is secured to the trailer  
The trailer lights are connected and checked  
Coupling to the Tow Vehicle  
Follow all of the safety precautions and instructions in this  
manual to ensure safety of persons, equipment, and satis-  
factory life of the trailer.Always use an adequate tow ve-  
hicle and hitch. If the vehicle or hitch is not properly se-  
lected and matched to the Gross Vehicle Weight Rating  
(GVWR) of your trailer, you can cause an accident that could  
lead to death or serious injury.  
DANGER - Hitch/Tow Vehicle Load Rating  
Use of a hitch with a load rating less than the load rating  
of the trailer can result in loss of control and may lead to  
death or serious injury.  
If you already have a tow vehicle, know your vehicle tow  
rating and make certain the trailer’s rated  
capacity is less than or equal to the tow vehicle’s rated tow-  
ing capacity. If you already have (or plan to buy) a trailer,  
make certain that the tow rating of the tow vehicle is equal  
to or greater than that of the trailer.  
Use of a tow vehicle with a towing capacity less than the  
load rating of the trailer can result in loss of control, and  
may lead to death or serious injury.  
Be sure your hitch and tow vehicle are rated for the Gross  
Vehicle Weight Rating of your trailer.  
The trailer VIN tag contains the critical safety  
information for the use of your trailer. Again, be sure your  
hitch and tow vehicle are rated for the Gross Vehicle Weight  
Rating of your trailer.

If NHTSA receives similar complaints, it may open an  
investigation, and if it finds that a safety defect exists in a  
group of vehicles, it may order a recall and remedy  
campaign. However, NHTSA cannot become involved in  
individual problems between you, your dealer, or us.  
To contact NHTSA, you may either call the Vehicle Safety  
Hotline toll-free at 1-888-327-4236 (TTY: 1-800-424-9153),  
It takes longer to get up to speed, you need more room to  
turn and pass, and more distance to stop when towing a  
trailer. You will need to spend time adjusting to the different  
feel and maneuverability of the tow vehicle with a loaded  
trailer.  
Because of the significant differences in all aspects of ma-  
neuverability when towing a trailer, the hazards and risks of  
injury are also much greater than when driving without a  
trailer. You are responsible for keeping your vehicle and  
trailer in control, and for all the damage that is caused if you  
lose control of your vehicle and trailer.

As you did when learning to drive an automobile, find an  
open area with little or no traffic for your first practice trailering.  
Of course, before you start towing the trailer, you must  
follow all of the instructions for inspection, testing, loading  
and coupling. Also, before you start towing, adjust the  
mirrors so you can see the trailer as well as the area to the  
rear of it.  
You can also obtain other information about motor vehicle  
Inoperable Brakes, Lights or Mirrors  
Be sure that the brakes and all of the lights on your trailer  
are functioning properly before towing your trailer. Check  
the trailer taillights by turning on your tow vehicle headlights.  
Check the trailer brake lights by having someone step on  
the tow vehicle brake pedal while you look at trailer lights.  
Do the same thing to check the turn signal lights. (See  
Trailer Wiring Diagram section in this manual.)  
Drive slowly at first, 5 m.p.h. or so, and turn the wheel to get  
the feel of how the tow vehicle and trailer combination  
responds. Next, make some right and left hand turns. Watch  
in your side mirrors to see how the trailer follows the tow  
vehicle. Turning with a trailer attached requires more room.  
Standard mirrors usually do not provide adequate visibility  
for viewing traffic to the sides and rear a towed trailer. You  
must provide mirrors that allow you to safely observe  
approaching traffic.  
Stop the rig a few times from speeds no greater than 10  
m.p.h. If your trailer is equipped with brakes, try using  
different combinations of trailer/electric brake and tow  
vehicle brake. Note the effect that the trailer brakes have  
when they are the only brakes used. When properly  
adjusted, the trailer brakes will come on just before the tow  
vehicle brakes.  
It will take practice to learn how to back up a tow vehicle  
with a trailer attached. Take it slow. Before backing up, get  
out of the tow vehicle and look behind the trailer to make  
sure that there are no obstacles.  
WARNING - CheckingTaillights/Brakelights  
Improper electrical connection between the tow vehicle  
and the trailer will result in inoperable lights and electric  
brakes, and can lead to collision.  
Before each tow:  
Check that the taillights, brake lights and turn  
signals work  
Check that the electric brakes work by operating the  
brake controller inside the tow vehicle

TRAILER SAFETY GUIDELINES  
Some drivers place their hands at the bottom of the steering  
wheel, and while the tow vehicle is in reverse, “think” of the  
hands as being on the top of the wheel. When the hands  
move to the right (counter-clockwise, as you would do to  
turn the tow vehicle to the left when moving forward), the  
rear of the trailer moves to the right. Conversely, rotating  
the steering wheel clockwise with your hands at the bottom  
of the wheel will move the rear of the trailer to the left while  
backing up.  
PSIC: The tire pressure (Pounds per Square Inch)  
measured when Cold.  
VIN: The Vehicle Identification Number.  
EMPTY WEIGHT: Some information that comes with the  
trailer (such as the Manufacturer’s Statement of Origin) is  
not a reliable source for “empty” or “net” weight. The ship-  
ping documents list average or standard weights and your  
trailer may be equipped with options.  
If you are towing a bumper hitch rig, be careful not to allow  
the trailer to turn too much, because it will hit the rear of the  
tow vehicle. To straighten the rig, either pull forward or turn  
the steering wheel in the opposite direction.  
To determine the “emptyor “netweight of your trailer, weigh  
it on an axle scale. To find the weight of the trailer using an  
axle scale, you must know the axle weights of your tow  
vehicle without the trailer coupled. Some of the trailer  
weight will be transferred from the trailer to the tow vehicle

The trailer VIN Tag contains the following critical safety  
information for the use of your trailer.  
GAWR: The maximum gross weight that an axle can  
support. It is the lowest of axle, wheel, or tire rating.  
Usually, the tire or wheel rating is lower than the axle rating,  
and determines GAWR.  
Figure 26. VIN Tag Location  
GVWR: The maximum allowable gross weight of the trailer  
and its contents. The gross weight of the trailer includes the  
weight of the trailer and all of the items within it (such as the  
pump with water, engine, and other ITEMS). GVWR is some-  
times referred to as GTWR (GrossTrailer Weight Rating), or  
MGTW (Maximum Gross Trailer Weight). GVWR, GTWR  
and MGTW are all the same rating.  
The sum total of the GAWR for all trailer axles may be less  
than the GVWR for the trailer, because some of the trailer  
load is to be carried by the tow vehicle, rather than by the  
trailer axle(s). The total weight of the cargo and trailer must  
not exceed the GVWR, and the load on an axle must not  
exceed its GAWR.

the coupler-to-hitch connection comes apart.  
Trailer Lighting (and Braking) Connector.  
Suspension System  
A device that connects electrical power from the tow ve-  
hicle to the trailer. Electricity is used to turn on brake lights,  
running lights, and turn signals as required. In addition, if  
your trailer has a separate braking system, the electrical  
connector will also supply power to the brakes from the tow  
vehicle.  
Sway bars, shock absorbers, heavy duty springs, heavy  
duty tires and other suspension components may be required  
to sufficiently tow the Dry Prime trailer and pump.  
Brake Controller  
For trailers equipped with electric brakes, the electric brake  
controller is part of the tow vehicle and is essential in the  
operation of the electric brakes on the trailer. The brake  
controller is not the same as the safety breakaway brake  
system that may be equipped on the trailer.  
Breakaway System  
If the trailer coupler connection comes loose, the breakaway  
system can actuate emergency electric or surge brakes de-  
pending on the type of actuator on the trailer. The breakaway  
cable must be rigged to the tow vehicle with  
appropriate slack that will activate the system if the coupler  
connection comes loose.  
Side View Mirrors  
The size of the trailer that is being towed and your state law  
regulations determine the size of the mirrors. However, some  
states prohibit extended mirrors on a tow vehicle, except  
while a trailer is actually being towed. In this situation, de-  
tachable extended mirrors are necessary. Check with your  
dealer or the appropriate state agency for mirror requirements.  
Jackstand  
A device on the trailer that is used to raise and lower the  
coupler. The jack is sometimes called the “landing gear” or  
the “tongue jack”.  
Heavy Duty Flasher  
A Heavy Duty Flasher is an electrical component that may  
be required when your trailer turn signal lights are attached  
to the tow vehicle flasher circuit.  
WARNING  
An improperly coupled trailer can result in death or serious  
injury.  
Electrical Connector  
DO NOT move the trailer until:  
An Electrical Connector connects the light and brake  
systems on the trailer to the light and brake controls on the  
towing vehicle.  
The coupler is secured and locked to hitch;  
The safety chains are secured to the tow vehicle  
The trailer jack(s) are fully retracted.  
Emergency Flares and EmergencyTriangle Reflectors  
It is wise to carry these warning devices even if you are not  
towing a trailer. It is particularly important to have these  
when towing a trailer because the hazard flashers of your  
towing vehicle will not operate for as long a period of time  
when the battery is running both the trailer lights and tow  
vehicle lights.  
DO NOT tow the trailer on the road until:  
Tires and wheels are checked;  
The trailer brakes are checked;  
The breakaway switch is connected to the tow vehicle;  
The load is secured to the trailer  
The trailer lights are connected and checked.

CouplerTypes  
The load rating of the coupler and the necessary ball size  
are listed on the trailer tongue. You must provide a hitch  
and ball for your tow vehicle where the load rating of the  
hitch and ball is equal to or greater than that of your trailer.  
The Dry Prime pump is shipped from the factory with a 2-5/  
16-inch ball coupler. A pintle eye coupler can be purchased  
as an alternative method (option) for towing. Both types of  
couplers will be discussed in this manual.  
Also, the ball size must be the same as the coupler size. If  
the hitch ball is too small, too large, is underrated, is loose  
or is worn, the trailer can come loose from the tow vehicle  
and may cause death or serious injury.  
Ball Hitch Coupler  
Pintle Eye Coupler  
Ball Hitch Coupler  
THE TOW VEHICLE, HITCH AND BALL MUST HAVE A  
RATED TOWING CAPACITY EQUAL TO OR GREATER  
THAN THE TRAILER Gross Vehicle Weight Rating  
(GVWR). IT IS ESSENTIAL THAT THE HITCH BALL BE  
OF THE SAME SIZE AS THE COUPLER.  
A ball hitch coupler (Figure 27) connects to a ball that is  
located on or under the rear bumper of tow vehicle. This  
system of coupling a trailer to a tow vehicle is sometimes  
referred to as “bumper pull.”  
A ball hitch trailer may be fitted with a tongue jack that can  
raise and lower the coupler. The tongue jack is mounted to  
the A-frame (front, or tongue) part of the trailer. By rotating  
the jack handle clockwise, the jack will extend and raise the  
tongue of the trailer.  
The ball size and load rating (capacity) are marked on the  
ball; hitch capacity is marked on the hitch.  
When replacing a ball, the load  
rating must match or exceed the  
GVWR of the trailer.  
Before coupling the tow vehicle to  
the trailer, be sure the size and rat-  
Figure 27. Ball Hitch Coupler

ing of hitch ball match the size  
and rating of the coupler. Hitch  
balls and couplers are marked with  
their size and rating.  
Before each tow, coat the ball with a thin layer of automotive  
bearing grease to reduce wear and ensure proper operation;  
and check the locking device that secures the coupler to the  
ball for proper operation.  
WARNING - Hitch Ball Load Rating  
Coupler-to-hitch mismatch can result in uncoupling,  
leading to death or serious injury.  
If you see or feel evidence of wear, such as flat spots,  
deformations, pitting or corrosion, on the ball or coupler,  
immediately have your dealer inspect them to determine the  
proper action to prevent possible failure of the ball and  
coupler system. All bent or broken coupler parts must be  
replaced before towing the trailer.  
Be sure the LOAD RATING of the hitch ball is equal or  
greater than the load rating of the coupler.  
Be sure the SIZE of the hitch ball matches the size of  
the ball coupler.  
The coupler handle lever must be able to rotate freely and  
automatically snap into the latched position. Oil the pivot  
points, sliding surfaces, and spring ends with SAE 30W motor  
oil. Keep the ball socket and latch mechanism clean. Dirt or  
contamination can prevent proper operation of the latching  
mechanism.

Be sure the hitch ball is tight to the hitch before coupling  
the trailer.  
Lower the trailer (Figure 28) until the coupler fully en-  
gages the hitch ball.  
Rock the ball to make sure it is tighten to the hitch, and  
visually check that the hitch ball nut is solid against the  
lock washer and hitch frame.  
Engage the coupler locking mechanism. In the engaged  
position, the locking mechanism securely holds the  
coupler to the hitch ball.  
Wipe the inside and outside of the coupler, clean and  
inspect it visually for cracks and deformations; feel the  
inside of the coupler for worn spots and pits.  
Insert a pin or lock through the hole in the locking  
mechanism.  
Be sure the coupler is all the way on the hitch ball and  
the locking mechanism is engaged. A properly engaged  
locking mechanism will allow the coupler to raise the  
rear of the tow vehicle. Using the trailer jackstand, verify  
that you can raise the rear of the tow vehicle by  
1-inch after the coupler is locked to the hitch.  
Be sure the coupler is secured tightly to the tongue of  
the trailer. All coupler fasteners must be visibly solid  
against the trailer frame.  
The bottom surface of the coupler to be above the top  
of the hitch ball. Use the tongue jackstand to support  
the trailer tongue.Wood or concrete blocks may also be  
used.  
Lower the trailer so that its entire tongue weight is held  
by the hitch.  
Raise the jackstand to a height where it will not interfere  
with the road.  
Coupling the Trailer to the Tow Vehicle (Ball Coupler)  
Lubricate the hitch ball and the inside of the coupler  
with a thin layer of automotive bearing grease.  
Slowly back up the tow vehicle so that the hitch ball is  
near or aligned under the coupler.  
Overloading can damage the  
tongue jack. DO NOT use the  
tongue jack to raise the tow vehicle  
more than 1 inch.  
Using the jackstand at the front of trailer (tongue), turn  
the jackstand crank handle to raise the trailer. If the ball  
coupler does not line up with the hitch ball, adjust the  
position of the tow vehicle.  
If the coupler cannot be secured to the hitch ball, do not  
tow the trailer. Call your dealer for assistance. Lower the  
trailer so that its entire tongue weight is held by the hitch,  
and continue retracting the jack to its fully retracted posi-  
tion.  
Open the coupler locking mechanism. Ball couplers have  
a locking mechanism with an internal moving piece and  
an outside handle. In the open position, the coupler is  
able to drop fully onto the hitch ball.

connected to the tow vehicle on one end and to the emer-  
gency brake lever located on the hydraulic actuator on the  
other end.  
B. Loop around a frame member of the tow vehicle  
or holes provided in the hitch system (but, DO  
NOT attach them to an interchangeable part of  
the hitch assembly).  
C. Have enough slack to permit tight turns, but not  
be close to the road surface, so if the trailer un  
couples, the safety chains can hold the tongue  
up above the road.  
Breakaway Electric Braking System  
For Dry Prime pump trailers equipped with an electric brak-  
ing system, the electric breakaway brake system includes a  
DC power source, a switch with a pull pin, and a breakaway  
brake controller.You must periodically charge the battery to  
keep the breakaway brake system in working order.  
WARNING - Safety Chains Rigging  
Improper rigging of the safety chains can result in loss of  
control of the trailer and tow vehicle, leading to death or  
serious injury, if the trailer uncouples from the tow vehicle.  
WARNING - Brakeaway Cable  
An ineffective breakaway brake system can result in a  
runaway trailer, leading to death or serious injury, if the  
coupler or ball hitch fails.  
Fasten chains to frame of tow vehicle. DO NOT fasten  
chains to any part of the hitch unless the hitch has  
holes or loops specifically for that purpose.  
Cross chains underneath hitch and coupler with  
enough slack to permit turning and to hold tongue up,  
if the trailer comes loose.  
Connect the breakaway cable to the tow vehicle;and NOT  
to the hitch, ball or support.  
Before towing the trailer, test the function of the breakaway  
brake system. If the breakaway brake system is not  
working, DO NOT tow the trailer. Have it serviced or  
repaired.

TRAILER SAFETY GUIDELINES  
ConnectingTrailer Lights  
Electric BrakeTesting  
Connect the trailer lights to the tow vehicle’s electrical  
system using the electric connectors at the front of the trailer  
(tongue). Reference the wiring diagram shown in the trailer  
wiring diagram section of this manual. Before towing the  
trailer check for the following:  
Perform the following when testing the electric braking sys-  
tem:  
Connect the pull pin cable to the tow vehicle so that the  
pull pin will be pulled out before all of the slack in the  
safety chains is taken up (see Figure 30). DO NOT  
connect the pullpin cable to a safety chain or to the  
hitch ball or hitch ball assembly. This would keep the  
breakaway brake system from operating when it is  
needed.  
Running lights (turn on tow vehicle headlights).  
Brake Lights (step on tow vehicle brake pedal).  
Backup Lights (place tow vehicle gear shift in reverse).  
Turn Signals (activate tow vehicle directional signal le-  
ver).  
When electric brakes are used, the tow vehicle will have  
an electric brake controller that sends power to the trailer  
brakes. Before towing the trailer on the road, you must  
operate the brake controller while trying to pull the trailer  
in order to confirm that the electric brakes operate. Re-  
move the pullpin from the switch. While towing the trailer  
at less than 5 m.p.h., manually operate the electric brake  
controller in the tow vehicle cab.  
WARNING - Improper Electrical Connections  
Improper electrical connection between the tow vehicle  
and the trailer will result in inoperable lights and electric  
brakes, and can lead to collision.  
Before each tow:  
y Check that the taillights, brake lights and turn signals  
You should feel the trailer resisting being towed, but the  
wheels will not necessarily be locked. If the brakes do  
not function, DO NOT tow the trailer until brakes are  
repaired.  
work  
y Check that the electric brakes work by operating the  
brake controller inside the tow vehicle.  
Uncoupling the Ball Hitch  
Follow these steps to uncouple ball hitch from tow vehicle:  
Immediately replace the pullpin. The breakaway brake  
system battery discharges rapidly when the pullpin is  
removed.  
Block trailer tires to prevent the trailer from rolling,before  
jacking the trailer up.  
WARNING - Pullpin Replacement  
Failure to replace the pullpin will prevent brakes from  
working, leading to loss of control, serious injury or death.  
Disconnect the electrical connector.  
Disconnect the breakaway brake switch cable. Promptly  
replace the pullpin in the switchbox.  
Before extending jackstand, make certain the ground  
surface below the jackstand foot will support the tongue  
load.  
DO NOT tow the trailer with the  
breakaway brake system ON be-  
cause the brakes will overheat  
which can result in permanent  
brake failure.  
Rotate the jackstand handle (or crank) clockwise. This  
will slowly extend the jack and transfer the weightof the  
trailer tongue to the jack.  
Replace the breakaway brake bat-  
tery (if equipped) according to the  
battery at intervals specified by  
manufacturer.

WARNING - Hitch Ball Load Rating  
Coupler-to-hitch mismatch can result in uncoupling,  
leading to death or serious injury.  
The load rating of the coupler and the necessary pintle hitch  
size are listed on the trailer tongue. You must provide a  
pintle hitch and pintle coupler for your tow vehicle, where  
the load rating of the pintle hitch and pintle coupler is equal  
to or greater than that of your trailer.  
Be sure the LOAD RATING of the pintle hitch hook is  
equal or greater than the load rating of the pintle eye  
coupler.  
Be sure the SIZE of the pintle hitch hook matches the  
size of the pintle eye coupler.  
Also, the pintle hitch size must be the same as the pintle  
coupler size. If the hitch is too small, too large, is under-  
rated, is loose or is worn, the trailer can come loose from  
the tow vehicle, and may cause death or serious injury.  
WARNING - Defective Pintle Hitch Hook  
A worn, cracked or corroded pintle hitch hook can fail  
while towing, and may result in death or serious injury.  
Before coupling trailer, inspect the pintle hitch hook for  
wear, corrosion and cracks.  
Pintle Coupler and Pintle Hook  
Before each tow, check the locking device that secures the  
coupler to the pintle hook assembly.  
Replace worn or damaged pintle hitch hook.  
Rock the pintle eye coupler to make sure it is secured  
tightly to the hitch.  
The pintle hook lever must be able to operate freely and  
automatically snap into place into the latched position. Lightly  
oil the pivot points and sliding surfaces with SAE30W motor  
oil to prevent rust and help ensure proper operation of the  
latching mechanism.  
Wipe the inside and outside of the pintle coupler, clean  
and inspect it visually for cracks and deformations; feel  
the inside of the coupler for worn spots and pits.  
If you see or feel evidence of wear, such as flat spots, de-  
formations, pitting or corrosion, on the pintle hook or cou-  
pler, immediately have your dealer inspect them to deter-  
mine the proper action to prevent possible failure of the ball  
andcoupler system. All bent or broken coupler parts must  
be replaced before towing the trailer.  
Be sure the coupler is secured tightly to the tongue of  
the trailer. All coupler fasteners must be visibly solid  
against the trailer frame.  
Raise the bottom surface of the coupler to be above the  
top of the pintle hitch hook. Use the tongue jackstand  
to support the trailer tongue. Wood or concrete blocks  
may also be used.

TIRE SAFETY  
WARNING - Uncoupled Pintle Hitch Hook  
UnsafeTires, Lug Nuts orWheels  
A defective pintle hitch not properly fastened can result  
in uncoupling, leading to death or serious injury.  
Trailer tires and wheels are more likely to fail than car tires  
and wheels because they carry a heavier load. Therefore, it  
is essential to inspect the trailer tires before each tow.  
If a tire has a bald spot, bulge, cuts, is showing any cords,  
or is cracked, replace the tire before towing. If a tire has  
uneven tread wear, take the trailer to a dealer service center  
for diagnosis.  
Be sure the pintle hook is securly tighten to the tow vehicle  
before coupling the trailer.  
Coupling the Trailer to the Tow Vehicle (Pintle Coupler)  
Slowly back up the tow vehicle so that the pintle hitch  
hook is near or aligned under the pintle eye ring coupler.  
Uneven tread wear can be caused by tire imbalance, axle  
misalignment or incorrect inflation.  
Tires with too little tread will not provide adequate tracking  
on wet roadways and can result in loss of control, leading to  
death or serious injury.  
Using the jackstand at the front of trailer (tongue), turn  
the jackstand crank handle to raise the trailer. If the  
pintle eye coupler does not line up with the pintle hitch  
hook, adjust the position of the tow vehicle.

The proper tightness (torque) for lug nuts is listed in the lug  
nut tightening section of this manual. Use a torque wrench  
to tighten the lug nuts. If you do not have a torque wrench,  
use a lug wrench (from your tow vehicle) and tighten the  
nuts as much as you can. Then have a service garage or  
trailer dealer tighten the lug nuts to the proper torque.  
Insert a pin or lock through the hole in the locking  
mechanism.  
Be sure the pintle hook is inserted completely through  
the eye ring and the locking mechanism is engaged. A  
properly engaged locking mechanism will allow the cou-  
pler to raise the rear of the tow vehicle. Using the trailer  
jack, test to see that you can raise the rear of the tow  
vehicle by1-inch after the coupler is locked to the hitch.  
WARNING - Lug NutTightening  
Metal creep between the wheel rim and lug nuts will cause  
rim to loosen and could result in a wheel coming off,  
leading to death or serious injury.  
Lower the trailer so that its entire tongue weight is held  
by the hitch.  
Tighten lug nuts before each tow.  
Raise the jackstand to a height where it will not interfere

TIRE SAFETY  
Lug nuts are also prone to loosen after first being assembled.  
When driving a new trailer (or after wheels have been  
remounted), check to make sure they are tight after the first  
10, 25 and 50 miles of driving and before each tow  
thereafter.  
Failure to perform this check can result in a wheel parting  
from the trailer and a crash, leading to death or serious  
injury.  
Determining Load Limit of Trailer  
Determining the load limits of a trailer includes more than  
understanding the load limits of the tires alone. On all trail-  
ers there is a Federal certification/VIN label that is located  
on the forward half of the left (road) side of the unit. This  
certification/VIN label will indicate the trailer’s GrossVehicle  
Weight Rating (GVWR). This is the most weight the fully  
loaded trailer can weigh. It will also provide the Gross Axle  
Weight Rating (GAWR).This is the most a the axle can weigh.  
WARNING - Lug Nut Loosening  
There is a vehicle placard (Figure 33) located in the same  
location as the certification label described above.This plac-  
ard provides tire and loading information. In addition, this  
placard will show a statement regarding maximum cargo  
capacity.  
Lug nuts are prone to loosen after initial installation, which  
can lead to death or serious injury.  
Check lug nuts for tightness on a new trailer or when  
wheel(s) have been remounted after the first 10, 25 and  
50 miles of driving.

WARNING - Tire Pressure  
Improper tire pressure can result in a blowout and loss of  
control, which can lead to death or serious injury.  
If additional work items (hoses, tools, clamps etc.) are go-  
ing to be added to the trailer, be sure they are distributed  
evenly to prevent overloading front to back and side to side.  
Heavy items should be placed low and as close to the axle  
positions as reasonable. Too many items on one side may  
overload a tire.  
Be sure tires are inflated to pressure indicated on side  
wall before towing trailer.  
Excessive loads and/or underinflation cause tire  
overloading and, as a result, abnormal tire flexing occurs.  
This situation can generate an excessive amount of heat  
within the tire. Excessive heat may lead to tire failure. It is  
the air pressure that enables a tire to support the load, so  
proper inflation is critical. The proper air pressure may be  
found on the certification/VIN label and/or on the Tire  
and Loading Information placard. This value should never  
exceed the maximum cold inflation pressure stamped on  
the tire.

TIRE SAFETY  
Step 1.  
Studies of tire safety show that maintaining proper tire  
pressure, observing tire and vehicle load limits (not carrying  
more weight in your vehicle than your tires or vehicle can  
safely handle), avoiding road hazards and inspecting tires  
for cuts, slashes and other irregularities are the most  
important things you can do to avoid tire failure, such as  
tread separation or blowout and flat tires. These actions,  
along with other care and maintenance activities, can also:  
Locate the statement, “The weight of cargo should never  
exceed XXX kg or XXX lbs.,on your vehicle’s  
Tire and Loading Information placard(Figure XX).This figure  
equals the available amount of equipment load capacity.  
Step 2.  
Determine the weight of the equipment being loaded on the  
tow vehicle. That weight may not safely exceed the avail-  
able equipment load capacity. The trailer’s Tire Information  
Placard is attached adjacent to or near the trailer’sVIN (Cer-  
tification) label at the left front of the trailer (See Figure 33).

Increase the tire life  
Step 1.  
Locate the statement, “The combined weight of  
occupants and cargo should never exceed XXX lbs.,on  
your vehicle’s placard.  
Use the information contained in this section to make tire  
safety a regular part of your vehicle maintenance routine.  
Recognize that the time you spend is minimal compared  
with the inconvenience and safety consequences of a flat  
tire or other tire failure.  
Step 2.  
Determine the combined weight of the driver and passen-  
gers who will be riding in your vehicle.  
Tire Fundamentals  
Step 3.  
Subtract the combined weight of the driver and  
passengers from XXX kilograms or XXX pounds.  
Federal law requires tire manufacturers to place standard-  
ized information on the sidewall of all tires (Figure 34). This  
information identifies and describes the fundamental char-  
acteristics of the tire and also provides a tire identification  
number for safety standard certification and in case of a  
recall.  
Step 4.  
The resulting figure equals the available amount of cargo and  
luggage capacity. For example, if the “XXX” amount e q u a l s  
1400 lbs. and there will be five 150 lb.  
passengers in your vehicle, the amount of available cargo and  
luggage capacity is 650 lbs. (1400-750 (5 x 150) = 650 lbs.).  
Step 5.  
Determine the combined weight of luggage and cargo being  
loaded on the vehicle. That weight may not safely  
exceed the available cargo and luggage capacity  
calculated in Step 4.  
If your vehicle will be towing a trailer, load from your trailer  
will be transferred to your vehicle. Consult the tow vehicle’s  
manual to determine how this weight transfer reduces the  
available cargo and luggage capacity of your vehicle.

TIRE SAFETY  
P: The “P” indicates the tire is for passenger vehicles.  
U.S. DOT Tire Identification Number: This begins with  
the letters “DOT” and indicates that the tire meets all federal  
standards. The next two numbers or letters are the plant  
code where it was manufactured, and the last four numbers  
represent the week and year the tire was built. For example,  
the numbers 3197 means the 31st week of 1997.The other  
numbers are marketing codes used at the manufacturer’s  
discretion. This information is used to contact consumers  
if a tire defect requires a recall.  
Next number: This three-digit number gives the width in  
millimeters of the tire from sidewall edge to sidewall edge. In  
general, the larger the number, the wider the tire.  
Next number: This two-digit number, known as the aspect  
ratio, gives the tire’s ratio of height to width. Numbers of 70  
or lower indicate a short sidewall for improved steering  
response and better overall handling on dry pavement.  
P: The “R” stands for radial. Radial ply construction of tires  
Tire Ply Composition and Materials Used: The number  
of plies indicates the number of layers of rubber-coated fabric in  
the tire. In general, the greater the number of plies, the more  
weight a tire can support. Tire manufacturers also must indi-  
cate the materials in the tire, which include steel, nylon, poly-  
ester, and others.  
has been the industry standard for the past 20 years.  
Next number: This two-digit number is the wheel or rim  
diameter in inches. If you change your wheel size, you will  
have to purchase new tires to match the new wheel  
diameter.  
Next number: This two- or three-digit number is the tire’s  
load index. It is a measurement of how much weight each  
tire can support.You may find this information in your owner’s  
manual. If not, contact a local tire dealer. Note:You may not  
find this information on all tires because it is not required by  
law.  
Maximum Load Rating: This number indicates the maxi-  
mum load in kilograms and pounds that can be carried by  
the tire.  
Maximum Permissible Inflation Pressure: This number  
is the greatest amount of air pressure that should ever be  
put in the tire under normal driving conditions.  
M+S:  
The “M+S” or “M/S” indicates that the tire  
UniformTire Quality Grading Standards (UTQGS)  
has some mud and snow capability. Most radial tires have  
these markings; hence, they have some mud and snow ca-  
pability.  
Treadwear Number: This number indicates the tire’s wear  
rate.The higher the treadwear number is, the longer it should  
take for the tread to wear down. For example, a tire graded  
400 should last twice as long as a tire graded 200.  
Speed Rating: The speed rating denotes the speed at which  
a tire is designed to be driven for extended periods of time.  
The ratings range from 99 miles per hour (mph) to 186 mph.  
These ratings are listed in Table 7. Note: You may not find  
this information on all tires because it is not required by law.  
Traction Letter: This letter indicates a tire’s ability to stop  
on wet pavement. A higher graded tire should allow you to  
stop your car on wet roads in a shorter distance than a tire  
with a lower grade.Traction is graded from highest to lowest  
as “AA”,A”, “B”, and “C”.  
Table 7. Speed Rating  
Temperature Letter: This letter indicates a tire’s resistance  
to heat. The temperature grade is for a tire that is inflated  
properly and not overloaded. Excessive speed, underinflation  
or excessive loading, either separately or in combination,  
can cause heat build-up and possible tire failure.From high-  
est to lowest, a tire’s resistance to heat is graded as “A”,  
“B”, or “C”.

TIRE SAFETY  
Make sure your tire valves have valve caps.  
Reference Figure 35 for additional tire information for light  
trucks.  
ALWAYS check tire pressure on tow vehicle and trailer  
before towing. Check tire pressure at least once a month.  
DO NOT overload tow vehicle. Check the tire  
information and loading placard for safe allowable tire  
loading conditions.  
Tire Repair  
The proper repair of a punctured tire requires a plug for the  
hole and a patch for the area inside the tire that surrounds  
the puncture hole. Punctures through the tread can be  
repaired if they are not too large, but punctures to the sidewall  
should not be repaired. Tires must be removed from the  
rim to be properly inspected before being plugged and patched.  
Figure 35. UTQGS Tire Information  
Replacing Worn or DamagedTires  
Replace the tire before towing the trailer if the tire treads  
have less than 1/16 inch depth or the telltale bands are  
visible. Check inflation pressure weekly during use to insure  
the maximum tire life and tread wear. A bubble, cut or bulge  
in a side wall can result in a tire blowout. Inspect both side  
walls of each tire for any bubble, cut or bulge; and replace a  
damaged tire before towing the trailer.  
Tires for light trucks have other markings besides those  
found on the sidewalls of passenger tires.  
LT: The “LT” indicates the tire is for light trucks or trailers.  
ST: An “ST” is an indication the tire is for trailer use only.  
Max. Load Dual kg (lbs) at kPa (psi) Cold: This informa-  
tion indicates the maximum load and tire pressure when the  
tire is used as a dual, that is, when four tires are put on each  
rear axle (a total of six or more tires on the vehicle).  
Table 8 below will help pinpoint the causes and solutions of  
tire wear problems.  
Max. Load Single kg (lbs) at kPa (psi) Cold  
This information indicates the maximum load and tire  
pressure when the tire is used as a single.  
Load Range  
This information identifies the tire’s load-carrying capabili-  
ties and its inflation limits.  
Tire Safety Tips  
Slow down if you have to go over a pothole or other  
object in the road.  
DO NOT run over curbs or other foreign objects in the  
roadway, and try not to strike the curb when parking.  
Check tire inflation pressure weekly during use to in-  
sure the maximum tire life and tread wear.  
DO NOT bleed air from tires when they are hot.  
Inspect tires for uneven wear patterns on the tread,  
cracks, foreign objects, or other signs of wear or trauma.  
Remove bits of glass and foreign objects wedged in the  
tread.

Lug NutTorque Requirements  
WARNING - Flying Objects  
It is extremely important to apply and maintain proper wheel  
mounting torque on the trailer. Be sure to use only the fas-  
teners matched to the cone angle of the wheel. Proper pro-  
cedure for attachment of the wheels is as follows:  
ALWAYS wear safety glasses when  
removing or installing force fitted parts  
DO NOT attemp to repair or modify a  
wheel. DO NOT install an inner-tube to  
1. Start all wheel lug nuts by hand.  
correct a leak through through the rim. If  
the rim is cracked, the air pressure in the inner tube may  
cause pieces of the rim to explode (break off) with great  
force and cause serious eye or bodily injury.  
2. Torque all lug nuts in sequence.See Figure 36. DO NOT  
torque the wheel lug nuts all the way down.Tighten each  
lug nut in 3 separate passes as defined by Table 9.  
3. Check to see if the lug nuts are tight after the first 10, 25  
and 50 miles of driving and before each tow thereafter.  
Wheel Rims  
If the trailer has been struck, or impacted, on or near the  
wheels, or if the trailer has struck a curb, inspect the rims for  
damage (i.e. being out of round); and replace any damaged  
wheel. Inspect the wheels for damage every year, even if no  
obvious impact has occurred.

90-120  
90-120  
To check wheel bearings, jack trailer and check wheels for  
side-to-side looseness. If the wheels are loose, or spin with  
a wobble, the bearings must be serviced or replaced. Check  
inflation pressure weekly during use to insure the maximum  
tire life and tread wear.Most trailer axles are built with sealed  
bearings that are not serviceable. Sealed bearings must be  
replacedas complete units.  
NEVER! use an pneumatic  
air gun to tighten wheel lug  
nuts.  
WARNING - Lug NutTightening  
Over-tightening lug nuts will result in breaking the studs  
or permanently deforming the mounting stud holes in the  
wheels.  
WARNING - Lug Nut Inspection  
Lug nuts are prone to loosen after initial installation, which  
can lead to death or serious injury. Check all wheel lug  
nuts periodically.

Check to see that the drain,  
surge control and backflush  
valves are closed.  
Check vacuum gauge reading.  
If low vacuum reading, vacuum  
pump might not be producing  
rated vacuum level.  
Low  
Check the suction hose for loose  
fittings and check that the  
strainer is under the liquid.  
Check vacuum gauge reading.  
Check the water level in the  
hose below the fill cap. If level  
is above half full on the hose,  
check the vacuum pump  
temperature and check for water  
flow out of the vacuum pump  
discharge hose. Check vacuum  
pump hose for damage.  
If the vacuum reading is 20” or  
more, the vacuum pump is  
working properly.  
Shut off the pump, disconnect  
discharge hose and inspect the  
discharge check valve for wear  
or not closing completely. If the  
discharge check valve is  
leaking, a good piece of PVC  
discharge hose will collapse  
and the pump should prime.  
If the suction lift is too high,  
reduce suction lift to a  
maximum lift of 28 to 30 feet.  
If the temperature and water flow  
out of the vacuum pump is  
normal, shut off the pump,  
disconnect suction hose, do dry  
vacuum test, and check vacuum  
gauge. Check for air leaks  
including at the pump seal. If the  
oil level is low, add oil and redo  
dry vacuum test. No oil could  
indicate seal failure. Listen at the  
seal oil fill cap for an air leak.  
If the suction line is plugged, the  
suction hose inner liner is  
collapsed, the strainer is plugged  
or the suction is buried or stuck  
to the floor. Backflush to clean  
the strainer.  
If there is a continued failure to  
prime and build vacuum,  
disconnect the suction hose and  
do the dry vacuum test. If the  
vacuum reading is normal and  
there are no leaks, the problem  
is a suction hose leak. If vacuum  
reading is low, block off the  
pump discharge and redo dry  
vacuum test. If the vacuum is  
still low, look for a large air  
leak. If the seal oil level is low,  
add oil and redo dry vacuum  
test. No oil could indicate seal  
failure. Listen at seal oil fill cap  
for an air leak.  
If the strainer is clear, check the  
inside of the hose for  
obstructions. A collapsed hose  
will return to normal without  
vacuum. Replace the hose.  
Check vacuum at vacuum pump  
by disconnecting inlet hose. If  
low, disassemble vacuum pump  
and inspect.  
If the material pumped is too  
thick or viscous, use a larger  
diameter suction hose. If the  
specific gravity is too high, move  
the pump closer to the liquid.  
If the vacuum pump water  
temperature is high, or if there is  
no water flow visible, clean the  
filter in the water feed line. If a  
filter is not installed, clean the  
inlet orifice behind the vacuum  
pump turbine with a wire. If the  
problem persists, clean the  
water reservoir by flushing with  
clean water. A filter should be  
added.  
Primes but the flow is low.  
Reduced flow at higher heads  
could indicate that the impeller-  
wearplate clearance needs  
adjusting or that there is an  
obstruction in the impeller.
