WARNING  
HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY.  
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.  
Read and understand all instruction manuals before operating equipment.  
FLUID INJECTION HAZARD  
General Safety  
Pressure Relief Procedure  
This pressure washer generates very high fluid pressure.  
Spray from the gun, leaks or ruptured components can  
inject fluid through your skin and into your body and  
cause extremely serious bodily injury including the need  
for amputation. Also, fluid injected or splashed into the  
eyes or on the skin can cause serious damage.  
To reduce the risk of serious bodily injury, including fluid  
injection and splashing in the eyes or on the skin, always  
follow this procedure whenever you stop spraying for  
more than 10 minutes, when shutting down, and before  
checking or repairing any part of the system.  
1. Engage the trigger safety latch.  
2. Turn the sprayer off.  
NEVER point the spray gun or wand at anyone or at any  
part of the body . NEVER put hand or fingers over the  
spray tip.  
3. Remove the ignition cable from the spark plug.  
4. Shut off the water supply  
.
ALWAYS follow the Pressure Relief Procedure

5. Disengage the trigger safety latch and trigger the gun  
to relieve pressure, and then engage the trigger  
safety latch again.  
NEVER try to stop or deflect leaks with your hand or  
body.  
6. Before long–term (overnight) storage or transporting  
of the unit, disconnect the water supply and turn off  
the fuel supply valve.  
Be sure equipment safety devices are operating properly  
before each use.  
Spray Gun Safety Devices  
Be sure all gun safety devices are operating properly  
before each use. Do not remove or modify any part of the  
gun; this can cause a malfunction and result in serious

surgically as soon as possible. Do not delay  
treatment to research toxicity. Toxicity is a concern  
with some exotic coatings injected directly into the  
bloodstream. Consultation with a plastic surgeon or  
reconstructive hand surgeon may be advisable.  
SPRAY TIP SAFETY : Use extreme caution when  
cleaning or changing spray tips. If a spray tip clogs while  
spraying, engage the gun safety latch immediately

EQUIPMENT MISUSE HAZARD  
General Safety  
System Pressure  
Any misuse of the pressure washer or accessories, such  
as overpressurizing, modifying parts, using incompatible  
chemicals and fluids, or using worn or damaged parts,  
can cause them to rupture and result in fluid injection,  
splashing in the eyes or on the skin, or other serious  
bodily injury, fire, explosion or property damage.  
This sprayer can develop high operating pressures. Be  
sure that all spray equipment and accessories are rated  
to withstand the maximum working pressure of this  
sprayer. DO NOT exceed the maximum  
pressure of any component or accessory used in the  
system.  
working  
NEVER alter or modify any part of this equipment; doing  
so could cause it to malfunction.  
Chemical Compatibility  
CHECK all spray equipment regularly and repair or  
BE SURE that all chemicals used in the chemical injector  
are compatible with the wetted parts of the hose, gun,  
wand and tip, as given in the Technical Data (inside back  
cover). Always read the chemical manufacturer  
literature before using any chemical in this pressure  
washer.  
replace worn or damaged parts immediately  
.
ALWAYS wear protective eyewear and appropriate  
clothing. If using a chemical injector, read and follow the  
’s  
chemical manufacturer  
s literature for recommendations  
on additional protective equipment, such as a respirator  
.
HOSE SAFETY  
High pressure fluid in the hoses can be very dangerous. If  
the hose develops a leak, split or rupture due to any kind  
of wear, damage or misuse, the high pressure spray  
emitted from it can cause a fluid injection injury or other  
serious bodily injury or property damage.  
NEVER use a damaged hose. Before each use, check  
entire hose for cuts, leaks, abrasion, bulging cover , or  
damage or movement of the hose couplings. If any of  
these conditions exist, replace the hose immediately DO  
.
NOT try to recouple high pressure hose or mend it with  
tape or any other device. A repaired hose cannot contain  
the high pressure fluid.  
ALL FLUID HOSES MUST HA VE STRAIN RELIEFS  
ON BOTH ENDS. The strain reliefs help protect the hose  
from kinks or bends at or close to the coupling, which can  
result in hose rupture.  
HANDLE AND ROUTE HOSES CAREFULL Y. Do not  
pull on hoses to move the pressure washer. Do not use  
chemicals which are not compatible with the inner tube  
and cover of the hose. DO NOT expose Graco hose to  
TIGHTEN all fluid connections securely before each use.  
High pressure fluid can dislodge a loose coupling or allow  
high pressure spray to be emitted from the coupling.

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.  
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.  
2. Check fuel level.  
WARNING  
DO NOT refuel a hot engine. Refueling a hot  
engine could cause a fire. Use only fresh, clean  
regular or unleaded gasoline. Close the fuel  
shutoff valve during refueling.  
8. ALWAYS observe the following CAUTIONS to avoid  
costly damage to the pressure washer  
.
CAUTION  
DO NOT allow the pressure washer to idle for more  
than 10 minutes. Doing so may cause the  
recirculating 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.  
3. Turn on the water supply  
.
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.  
DO NOT run the pump dry , which will quickly  
damage the pump. Be sure the water supply is fully  
turned on before starting the pump.  
4. Trigger the gun until water sprays from the tip  
indicating that the air is purged from the system.  
5. Open the fuel shutoff valve. Be sure the spark plug  
ignition cable is pushed firmly onto the spark plug. On  
those units equipped with an ignition shutoff switch,  
put the switch in the “on” position and put the throttle  
in the “run” position.  
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 or scratch the pump. Keep this screen clean.  
DO NOT pump caustic materials; such materials  
may corrode the pump components.  
6. Start the engine.  
NOTE: For easier starting, have one person start the  
pressure washer while another person triggers  
the spray gun.  
9. See the chemical injector or sandblaster kit manual  
for detailed cleaning information if these accessories  
are used.
