SAFETY  
TO HELP PREVENT BODILY INJURY DUE TO LOSS OF  
TOWING SAFELY  
STABILITY OR CONTROL:  
Stopping distance increases with speed and weight of towed load.  
Travel slowly and allow extra time and distance to stop.  
• Do not exceed maximum towing capacity of towing vehi-  
cle listed in the vehicle operator's manual.  
Total towed weight must not exceed limits specified in towing vehi-  
cle operator's manual.  
• Do not exceed 5 mph.  
Excessive towed load can cause loss of traction and loss of control  
on slopes. Reduce towed weight when operating on slopes.  
• Do not tow this machine behind a motor vehicle such as a  
car or truck.  
Never allow children or others in or on towed equipment.  
• Do not tow this machine behind a ZTR (Zero Turn Radius)  
Mower.  
Use only approved hitches. Tow only with a machine that has a  
hitch designed for towing. Do not attach this machine except at the  
approved hitch point.  
SAFETY  
Follow the manufacturer's recommendations for weight limits for  
towed equipment and towing on slopes. Use counterweights or  
wheel weights as described in the towing vehicle operator's man-  
ual.  
Read the general safety operating precautions in your towing vehi-  
cle operator's manual for additional safety information.  
Operate Safely  
Do not turn sharply. Use additional caution when turning or operat-  
ing under adverse surface conditions. Use care when reversing. To  
avoid jack-knifing, do not allow towing vehicle wheels to contact  
drawbar.  
Use this machine for intended purpose only.  
This machine is intended for use in lawn care and home applica-  
tions. Do not tow behind a vehicle on a highway or in any high  
speed applications. Do not tow at speeds higher than maximum  
recommended towing speed.  
Do not shift to neutral and coast downhill.  
Protect Bystanders  
Towing speed should always be slow enough to maintain control.  
Travel slowly over rough ground.  
Keep bystanders away when you operate this machine  
Before you back look carefully behind for bystanders.  
Do not let children or an untrained person operate machine.  
Do not let anyone, especially children, ride on this machine or the  
towing vehicle. Riders are subject to injury such as being struck by  
foreign objects and being thrown off. Riders may also obstruct the  
operator's view, resulting in this machine being operated in an  
unsafe manner.  
Before you operate any feature of this machine, observe your sur-  
roundings and look for bystanders.  
Keep Riders Off Towed Attachment  
Keep riders off towed attachment.  
Check towing vehicle brake action before you operate. Adjust or  
service brakes as necessary.  
Riders on a towed attachment are subject to injury, such as being  
struck by objects and being thrown off the attachment during sud-  
den starts, stops and turns.  
Keep all parts in good condition and properly installed. Fix dam-  
aged parts immediately. Replace worn or broken parts. Replace all  
worn or damaged safety and instruction decals.  
Riders obstruct the operator's view, resulting in the attachment  
being used in an unsafe manner.

2. Align sprayer drawbar with towing machine drawbar.  
3. Install Hitch Pin (44) through sprayer drawbar and machine  
drawbar. Secure Hitch Pin with Hairpin Cotter (48).  
CAUTION: Avoid injury! If additional weight is  
required when towing, add weight at or forward of  
the rear wheels. Adding weight behind the rear  
wheels can affect machine steering. Refer to your  
towing machine manual.  
REMOVING SPRAYER  
Towing capacity will vary with weight of towing machine and opera-  
tor.  
Note:Refer to illustrations in the Installing Section, earlier in this manual.  
1. Park machine safely. (See Towing Machine manual.)  
2. Unload sprayer tank before disconnecting hitch towing vehicle.  
Example:  
If Towing Machine Weighs:  
Add Your Weight:  
400 lbs.  
200 lbs.  
600 lbs.  
CAUTION: Avoid injury! Keep body parts  
away from underneath towbar.  
Combined Weight Equals:  
To maintain stability using the machine in this example, you cannot  
safely tow more than 600 lbs. without first adding additional ballast  
to the towing machine.  
3. Remove hairpin cotter and hitch pin.  
4. Push sprayer away from machine. Block sprayer wheels.  
INSTALLING ELECTRICAL CONNECTIONS  
5. Install hitch pin and hairpin cotter pin in sprayer drawbar for  
storage.  
CAUTION: Avoid Injury! Avoid injury! Care  
should be used when working around batteries  
Use insulated tools when making battery connec-  
tions  
Heavy gloves and eye protection should be worn  
when making battery connections.  
1. Select the proper tools to remove the leads to the battery  
terminals.  
Note:If you do not have insulated tools, use electrical tape to wrap all exposed  
non-working surfaces of the tools. It is important to take steps to reduce  
the risk of causing an electrical spark.  
2. Put on gloves and eye protection.  
3. Verify that the read lead is attached to the positive (+) battery  
terminal and the black lead is attached to the negative (-) bat-  
tery terminal.  
L-1914 Rev. B 14.  
OPERATION  
Pump surge may occur when using the wand for fine mist applica-  
INSTALLING ELECTRICAL CONNECTIONS  
(Cont’d)  
tions. Do not allow this to occur. The pump is designed for continu-  
ous duty. Intermittent starting and stopping will cause the pump  
motor to overheat. To eliminate pump surge:  
4. Remove the battery leads.  
5. Using the Battery Connection Wiring Harness (6) attach the  
black lead and the black lead from your engine to the negative  
(-) battery terminal.  
a) Open the wand tip to a higher flow rate  
b) Create a by-pass that allows the pump to run continuous by  
removing one of the boom hoses near the tip (See Step 11).  
Remove the tank fill cap and place the hose in the tank. Open  
the valve for the boom slowlyuntil the pump runs continu-  
ously. Adjust the wand tip to the desired mist.  
6. Attach the red lead (with the fuse) of the Battery Connecting  
Wiring Harness and the red lead from your engine to the posi-  
tive (+) battery terminal.  
Note:The Battery Connection Wiring Harness contains a 15 amp blade type  
fuse.  
Note:If the battery is underneath the seat, ensure that both battery terminals  
and battery leads do not make contact with seat.  
7. Attach the Wiring Harness with Switch (5) to the connector ter-  
minal end of the Battery Connection Wiring Harness (6).  
BOOM OPERATIONS  
Boom spraying is the normal spraying configuration and is con-  
trolled by the operator in the seated position.  
Note:In most instances the terminal connector with the shorter leads from the  
Wiring Harness with Switch (5) are connected to the terminal connector  
on the Battery Connection Wiring Harness (6). Most users like the  
switch to lie in their laps or be convenient to the towing vehicle operator.  
The Wiring Harness with Switch (5) terminal connectors can be  
reversed to suit the need of the user.  
For spraying in a vertical orientation such as along fences or  
hedges, use the wand operation.  
APPLICATION RATE  
Wand  
CAUTION: Avoid Injury! Avoid injury! Care  
should be when routing the wiring harness to the  
sprayer.  
Understanding the following information about your sprayer will  
help to calibrate the application rate. The sprayer operates at a  
fixed pressure of 60 psi. This results in actual spraying time of 30  
minutes using the handgun.  
Do not place the wiring harness in areas that the  
wires can be pinched or damaged.  
Boom  
Place the wires to minimize a tripping hazard when  
getting on or off the towing vehicle.

8. Attach the other end of remaining terminal lead connector from  
the Wiring Harness with Switch (5) to the terminal lead connec-  
tor coming from the Pump (4). If the pump begins to run, use  
the switch to turn the pump off.

The pump motor supplied with your sprayer is a “demand flow”  
type pump. An internal pressure switch in the pump turns the pump  
off when the pressure reaches approximately 60psi. When the  
pump senses that pressure has dropped (by triggering the wand)  
the pump will again start and continue to run until 60psi is reached.  
Note:Pump surge should be avoided. It can cause the pump motor to over-  
heat resulting in damage to the pump. Refer to the Wand Operations  
Section for tips on how to avoid pump surge.  
WAND OPERATIONS  
The wand can be used for spraying in various applications from a  
steady stream to a fine mist. Adjust the spray pattern by turning the  
Wand Tip (31) clockwise for a fine mist or counterclockwise for a  
course spray.  
CAUTION: Avoid Injury! Always turn pump off  
when making adjustments to the Wand Tip. Wear  
eye protection.

OPERATION  
3. Determine how many tanks are required to complete the total  
TOWING VEHICLE REQUIREMENTS  
job:  
The lawn sprayer requires towing equipment with a 12-volt battery  
and charging system, and a towbar hitch in order to operate prop-  
erly.  
Amount of Water / Tank Capacity = Number of tanks from  
Step 1.  
If the number of tanks is less than 1.0 use 1.0  
The towing equipment should have operable brakes capable of  
controlling the loaded sprayer and towing vehicle.  
Example 1  
Example 2  
150 gal/ 25 = 6.0 tanks  
18 gal/ 25 = 0.7 tanks use 1.0 tank  
CALIBRATION OF SPEED  
By measuring off a distance of 50 or 100 feet, the speed of the tow-  
ing vehicle can be calibrated by selecting a gear and throttle posi-  
tion to cover the prescribed distance in the specified time as  
shown:

CALCULATION PROCEDURE FOR SPRAYER  
APPLICATION  
Example 1  
Example 2  
80oz./ 6.0 tanks = 13.3 oz./tank  
10 pints/ 1 tank = 10 pints  
Chemical labels normally show application rates in gallons per  
acre or gallons per square feet. Using the following method, one  
can determine the appropriate amount of water to use and speed  
to travel to adequately follow the manufactures recommended  
instructions.  
1. Based on the size of your yard, select the amount of water to  
be used. Use the formula:  
Application Rate x Area to be sprayed = Amount of water  
(from the Table1).  
Example 1  
Example 2  
Yard Size= 4 acresYard Size= 20,000 sf  
Using the Table 1 and the above formula:  
56.5 gal/ acre x 4acres= 225.6 gal@ 2mph 1.3 gal/ 1000 x 20,000sf= 26 gal@ 2mph  
37.5 gal/ acre x 4acres= 149.6 gal@ 3mph 0.9 gal/ 1000 x 20,000sf= 18 gal@ 3mph  
28.0 gal/ acre x 4acres= 112.0 gal@ 4mph 0.6 gal/ 1000 x 20,000sf= 12 gal@ 4mph  
22.5 gal/ acre x 4acres= 90.00 gal@ 5mph 0.5 gal/ 1000 x 20,000sf= 10 gal@ 5mph  
2. Choose the speed / amount of water you want to use.  
Example 1  
Example 2  
A comfortable speed  
for a lawn tractor is  
3 mph.  
Since 18 gallons can be  
done with only one filling:  
Choice = 149.6 ~ 150 gal@ 3mph  
Choice = 18 gallons @ 3mph
