Check for Shipping Damage  
Connect to Water Supply  
Check the unit for any damage that may have occurred in  
shipping. Notify the carrier immediately if there is any  
damage.  
CAUTION  
Before attaching to the water supply, check your  
local plumbing code regarding cross–connection  
to the water supply. If required, a backflow  
preventer may be installed.  
Set Up  
Connect the high pressure hose between the pump outlet  
and the gun inlet. Both of these connections are made  
with quick couplers.  
If inlet water pressure is over 60 psi (4.1 bar), a  
regulating water valve must be installed at the  
garden hose connection.  
CAUTION  
Do not exceed 160_F (70_C) inlet water  
temperature.  
Up to 100 ft (30 m) of high pressure hose may  
be used. Longer hoses may affect sprayer  
performance, and chemical injector performance,  
if used.  
Connect a hose with at least a 3/4 inch (19 mm) ID from  
the water supply to the unit’s 3/4 inch garden hose inlet.  
The supply hose should not be more than 50 ft (15 m)  
long  
Install the appropriate spray tip on the wand. See Install  
-
ing and Changing Spray Tips. If you are using a  
sandblaster kit, see its separate manual for installation  
instructions.  
NOTE: The water source at the unit must have a mini-  
mum flow rate equal to that of the unit (see Tech-  
nical Data, inside back cover).

Always use this start–up procedure to ensure that the  
unit is started safely and properly  
WARNING  
INJECTION HAZARD  
.
The system pressure must be manually  
1. Check oil levels:  
relieved to prevent the system from  
spraying accidentally. To reduce the risk  
of an injury from accidental spray from the gun,  
splashing fluid, or moving parts, follow the Pres-  
sure Relief Procedure whenever you:  
NOTE: All units are equipped with a low-oil sensor that  
shuts the engine off if the oil level falls below a  
certain level. If the unit stops unexpectedly,  
check both the oil and the fuel levels. Check the  
oil level each time the unit is refueled.

Pressure Relief Procedure  
WARNING  
1. Engage the trigger safety latch.  
2. Turn the sprayer off.  
FIRE HAZARD

refueling.  
4. Shut off the water supply  
.
5. Disengage the trigger safety latch and trigger the  
gun to relieve pressure, and then engage the  
trigger safety latch again.  
6. If you suspect that the spray tip or hose is  
completely clogged, or that pressure has not been  
fully relieved after following the steps above:  
Disengage the trigger safety latch and trigger the  
gun to relieve pressure. Wrap a rag around the  
hose end coupling and VERY SLOWLY loosen the  
coupling to relieve pressure gradually, then loosen  
completely. Now clear the tip or hose.  
CAUTION  
Never run the unit dry. Costly damage to the  
pump will result. Always be sure the water  
supply is completely turned on before operating.  
3. Turn on the water supply

indicating that the air is purged from the system.  
NOTE: For easier starting, have one person start the  
pressure washer while another person triggers  
the spray gun.  
5. Open the fuel shutoff valve. Be sure the spark plug  
ignition cable is pushed firmly onto the spark plug.  
Put the switch in the “on” position and put the  
throttle in the “run” position.  
If the engine is cold, completely close the engine  
choke. Grasp the starter rope, brace one foot on  
the pressure washer chassis and pull rope rapidly  
and firmly. Continue holding the rope as it returns.  
Pull and return the rope until the engine starts. In  
cool weather, the choke may have to be kept  
closed for 10 to 30 seconds before opening it to  
keep the engine running. Otherwise, open the  
choke as soon as the engine starts.  
CAUTION  
Do not allow the pressure washer to idle for more  
than 10 minutes. Doing so may cause the recir  
-
culating water to overheat and seriously damage  
the pump. Turn off the pressure washer if it will not  
be spraying or cleaning at least every 10 minutes.  
If heated inlet water is used, reduce this time  
further. Do not operate the pressure washer with  
the inlet water screen removed. This screen helps  
keep abrasive sediment out of the pump, which  
could clog the pump or damage the cylinders.  
Keep this screen clean. Do not pump caustic  
materials; such materials may corrode the pump  
components.  
If the engine is warm, leave the choke open, or  
just partly close it. Start the engine as described in  
the preceding paragraph. When it starts, be sure  
to open the choke completely  
.
7. Always engage the gun’s trigger safety latch  
whenever you stop spraying, even for a moment,  
to reduce the risk of fluid injection or splashing in  
the eyes or on the skin if the gun is bumped or  
triggered accidentally  
.
CAUTION  
Do not allow the starter rope to snap back against the  
engine. Return it gently to prevent damage to the  
recoil.  
8. Always observe the following CAUTIONS to avoid  
costly damage to the pressure washer

The SHERWIN–WILLIAMS Warranty  
and Disclaimers  
WARRANTY  
Graco warrants all equipment manufactured by it and bearing its name to be free from defects in material and workmanship on  
the date of sale by an authorized Graco distributor to the original purchaser for use. As purchaser s sole remedy for breach of this  
warranty, Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment proven defec  
-
tive. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written rec-  
ommendations.  
This warranty does not cover, and Graco shall not be liable for, any malfunction, damage or wear caused by faulty installation,  
misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of  
non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility with Graco  
equipment of structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, instal  
lation, 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 claim. 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.  
DISCLAIMERS AND LIMITATIONS  
The terms of this warranty constitute purchasers sole and exclusive remedy and are in lieu of any other warranties (express or  
implied), including warranty of merchantability or warranty of fitness for a particular purpose, and of any non–contractual  
liabilities, including product liabilities, based on negligence or strict liability. Every form of liability for direct, special or consequen  
-
tial damages or loss is expressly excluded and denied. In no case shall Graco’s liability exceed the amount of the purchase price.  
Any action for breach of warranty must be brought within two (2) years of the date of sale.  
EQUIPMENT NOT COVERED BY GRACO WARRANTY  
Graco makes no warranty, and disclaims all implied warranties of merchantability and fitness for a particular purpose, with  
respect to accessories, equipment, materials, or components sold but not manufactured by Graco. These items sold, but not  
manufactured by Graco (such as electric motor, 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.
