inlet of the unit.  
Be certain the trigger gun is locked in the “OFF” posi-  
tion.  
2. Connect the other end of the hose to your pressurized  
water supply. When connecting the water inlet to  
the water supply mains, local regulations of your  
water company must be observed. In some areas,  
the unti must not be connected directly to the public  
drinking water supply. This is to ensure that there is  
no feedback of the detergents into the water supply.  
(Direct connection is permitted if a back flow preventer  
is installed.  
3. Quick-connect the high pressure discharge hose to the  
water outlet of the unit.  
4. Connect the other end of the discharge hose to the  
gun assembly.  
The nozzle assembly should be disconnected from  
the gun/wand assembly at this time by retracting the  
locking ring on the quick-connect fitting to remove the  
nozzle.  
Follow the incoming water requirements listed below:  
1. Water pressure must be a minimum of 25 pounds per  
square inch (PSI) and a maximum of 125 PSI. (A typical  
outdoor faucet will generally supply this PSI if turned  
completely “ON”.)  
2. Incoming GPM must be approximately one gallon more  
than the outgoing GPM stated on the pressure washer  
nameplate. (You can check GPM by timing how long  
it takes to fill a 5 gallon container.)  
NOTICE  
Incoming water temperature must not exceed  
145°F. Excessive pump damage may result if the  
water temperature exceeds this acceptable level.  
Water supply  
Select a water supply hose which is a quality grade of  
garden hose measuring at least 3/4” ID and no longer  
than 50 feet.  
NOTICE  
Check the water inlet strainer to ensure it is clean and  
free of any obstructions. Periodic cleaning of the water  
strainer will help prevent pump problems.  
Damage to the equipment could occur. Never allow  
the unit to operate without the incoming water line  
attached and the water supply completely turned on.  
NOTICE  
As a strainer becomes obstructed, it restricts proper  
flow of water to the pump. This can result in cavita-  
tions which will cause premature failure of pump  
packings.

Pre-start inspection procedures  
INSTALLATION & PREPARATION  
INSTRUCTIONS  
Before starting the unit, perform the following proce-  
dures:  
Unloader  
Adjustable  
1. Check the oil level in the pump and engine.  
2. Inspect the water inlet strainer. Clean or replace if  
necessary. See “Water Supply” pg. 9.  
3. Check all hose connections to ensure they are securely  
tightened. See “Water Supply” pg. 9.  
The unloader valve on your machine is equipped with  
an adjustment knob to adjust the pressure. Should  
less pressure be required, simply turn the adjustment  
knob counterclockwise. To set back to maximum, turn  
adjustment knob completely clockwise. Do not over-  
tighten.  
Inspect for system fuel leaks. If a fuel leak is found,  
do not start unit. See “Fire & Ventilation Precau-  
tions” pg. 4. Be sure that all damaged parts are  
replaced and that the mechanical problems are cor-  
rected prior to operation of the unit. If you require  
service, contact Graco Customer Service.  
Inspect high pressure hoses for kinking, cuts and  
leaks. If a cut or leak is found, do not use hose.  
Replace hose before starting unit. See “Miscel-  
laneous Safety Precautions” pg. 5. Be sure that all  
damaged parts are replaced and that the mechani-  
cal problems are corrected prior to operation of the  
unit. If you require service, contact Graco Customer  
Service.  
NOTICE  
Do not overtighten the unLoader. Breakage could  
result in immediate loss of water pressure and  
costly repairs.  
Thermal relief valve  
To ensure the water temperature does not exceed  
acceptable levels, never allow the pressure washer to  
operate in the bypass mode (with the unit running and  
the trigger gun closed) for more than three minutes.  
A “thermal relief valve” has been added to this unit to  
protect the pump. It may begin to open and release  
water if the water temperature in the pump has ex-  
ceeded 140°F. This will allow fresh, cool water to enter  
the system.

OPERATING INSTRUCTIONS  
NOTICE  
Be certain the nozzle is not connected to the unit  
while priming the pump. Priming allows mineral de-  
posits to be released from the system which would  
obstruct or damage the nozzle assembly resulting in  
costly repairs.  
Priming the pump  
It is essential to prime the pump on initial start-up and  
each time the water supply is disconnected from the  
unit after initial use.  
1. Lay the high pressure hose out to remove any loops.  
Water flow will constrict the hose, creating tight loops  
if the hose is not straight.  
Note: The nozzle assembly should not be connected  
to the gun assembly at this time. See “Nozzle Connec-  
tion” pg. 9.  
2. With the trigger gun locked in the “OFF” position, turn  
the water supply completely on. Pointing the gun in a  
safe direction, unlock the trigger gun and squeeze the  
trigger.  
Low pressure water will begin flowing from the hose/  
gun assembly. This allows the unit to prime and purge  
any air from the system. The unit is primed when water  
flow is uninterrupted by air.  
3. Once the unit is primed, release the trigger and lock  
the gun in the “OFF” position. Securely connect the  
nozzle assembly. (See “Nozzle Connection” pg. 9)

3. To apply solution; unlock the trigger gun and squeeze  
the trigger. In a few moments a detergent/water mixture  
will exit the low pressure nozzle. Start spraying the  
lower portion of the surface being cleaned and move  
up, using long overlapping strokes. Applying from the  
bottom up helps avoid streaking. Allow to soak briefly.  
Do not allow detergent solution to dry on the surface.  
(Avoid working on hot surfaces or in direct sunlight to  
minimize the chances of the detergent drying, which  
may result in damaging painted surfaces.) Be certain  
to rinse a small section at a time.  
4. To rinse; lock the trigger gun in the “OFF” position,  
securely quick-connect the desired high pressure  
nozzle into the end of the wand. Unlock the trigger gun  
and spray. It will take about 30 seconds to purge all  
detergent from the line. For best rinsing results, start  
at the top and work down.  
OPERATING INSTRUCTIONS  
Cleaning with detergents  
Refer to “Detergent Cleaning Precautions” pg. 4 before  
working with detergents. Be certain to wear protective  
safety attire.  
Prepare detergent solution according to label directions.  
Never pump acids, alkaline, abrasive fluids or solvents  
through the unit.

knobs. Locate the clear vinyl hose which leads to the  
pump head.  
If your injector is equipped with an adjustment knob  
on the pump head, you may adjust the amount of  
detergent desired by turning the knob completely  
counterclockwise to set at the maximum siphon rate.  
If your injector is not equipped with an adjustment  
knob, the detergent ratio is preset and cannot be  
adjusted.  
5. Siphon a gallon of water through the low pressure  
detergent injection system after each use. This  
prevents the possibility of corrosion or detergent  
residue causing mechanical problems during the next  
use.  
Shutdown  
1. Immerse the detergent strainer into the detergent  
solution to allow detergent to siphon.  
1. Turn engine “OFF” as directed in the engine manual.  
2. Turn the water supply “OFF”.

Quick Couplers  
STORAGE & MAINTENANCE  
INSTRUCTIONS  
There is an o-ring seal inside the female quick coupler.  
This o-ring will deteriorate or, if the unit is allowed to  
pump without the high pressure hose or nozzle at-  
tached, the o-ring may be blown out occasionally.  
Simply insert a replacement o-ring to correct the leak.  
(Additional o-rings can be purchased from your dealer.)  
Engine  
The engine instructions that accompany your unit detail  
specific procedures for maintenance of the engine. Fol-  
lowing the engine manufacturer’s recommendations will  
extend engine work life.  
Belt Tension Adjustment  
To maintain peak performance of your pressure washer,  
it may be necessary to adjust the belt tension on occa-  
sion. Follow the procedure outlined below.  
Pump  
The pump oil must be changed after the first 25 hours  
of operation on all units. Once the initial oil change has  
been completed, it is recommended the oil be changed  
every 3 months or 250 hour intervals. If oil appears  
dirty or milky, changes may be required at a greater  
frequency. Add pump oil and fill only to the center of  
the sight glass (Refer to the parts listing for the correct  
pump oil). Do not overfill.  
1. Remove the belt guard and loosen the two nuts on each  
side of the pump. (Reference A) There are a total of  
4 nuts.  
2. Turn the cap screw (Reference B) clockwise until a 1/2  
inch belt deflection is noticed between the pulleys.  
3. Tighten the side nuts. (Reference A)  
4. Put a straight edge across both pulleys. If necessary,  
loosen one set of pulley screws and adjust in or out to  
properly align. Tighten the pulley screws and check  
the tension again.  
Nozzles  
Water flow through the spray nozzle will erode the ori-  
fice, making it larger, resulting in a pressure loss. Noz-  
zles should be replaced whenever pressure is less than  
85% of the maximum. The frequency of replacement  
will depend upon such variables as mineral content in  
the water and number of hours the nozzle is used.  
5. Replace the beltguard and tighten the fasteners  
securely.

Graco Standard Warranty  
Graco warrants all equipment referenced in this document which is manufactured by Graco and bearing its name  
to be free from defects in material and workmanship on the date of sale to the original purchaser for use. With  
the exception of any special, extended, or limited warranty published by Graco, Graco will, for a period of twelve  
months from the date of sale, repair or replace any part of the equipment determined by Graco to be defective. This  
warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written  
recommendations.  
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or  
wear caused by faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, neg-  
ligence, accident, tampering, or substitution of non-Graco component parts. Nor shall Graco be liable for malfunc-  
tion, damage or wear caused by the incompatibility of Graco equipment with structures, accessories, equipment  
or materials not supplied by Graco, or the improper design, manufacture, installation, operation or maintenance of  
structures, accessories, equipment or materials not supplied by Graco.  
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized  
Graco distributor for verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace  
free of charge any defective parts. The equipment will be returned to the original purchaser transportation prepaid.  
If inspection of the equipment does not disclose any defect in material or workmanship, repairs will be made at a  
reasonable charge, which charges may include the costs of parts, labor, and transportation.  
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, IN-  
CLUDING BUT NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PAR-  
TICULAR PURPOSE.  
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer  
agrees that no other remedy (including, but not limited to, incidental or consequential damages for lost profits, lost  
sales, injury to person or property, or any other incidental or consequential loss) shall be available. Any action for  
breach of warranty must be brought within two (2) years of the date of sale.  
GRACO MAKES NO WARRANTY, AND DISCLAIMS ALL IMPLIED WARRANTIES OF MERCHANTABILITY AND  
FITNESS FOR A PARTICULAR PURPOSE, IN CONNECTION WITH ACCESSORIES, EQUIPMENT, MATERIALS OR  
COMPONENTS SOLD BUT NOT MANUFACTURED BY GRACO. These items sold, but not manufactured by Graco  
(such as electric motors, switches, hose, etc.), are subject to the warranty, if any, of their manufacturer. Graco will  
provide purchaser with reasonable assistance in making any claim for breach of these warranties.  
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco sup-  
plying equipment hereunder, or the furnishing, performance, or use of any products or other goods sold hereto,  
whether due to a breach of contract, breach of warranty, the negligence of Graco, or otherwise.
