FUEL AND EMISSION HAZARDS  
NEVER fill the fuel tank while the unit is running or hot.  
The fuel used in this unit is combustible and when  
spilled on a hot surface can ignite and cause a fire.  
ALWAYS fill tank slowly to avoid spilling.  
NEVER alter the maximum throttle setting, which is  
factory set. Tampering with this adjustment can  
damage the pressure washer and will void the warranty  
.
NEVER operate the unit in a closed building. The  
exhaust contains carbon monoxide, a  
poisonous,  
odorless, invisible gas which can cause serious injury  
or death if inhaled.  
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 working  
pressure of any component or accessory used in the  
system.  
Chemical Compatibility  
NEVER alter or modify any part of this equipment;  
doing so could cause it to malfunction.  
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’s literature before using any chemical in  
CHECK all spray equipment regularly and repair or  
replace worn or damaged parts immediately

this pressure washer  
.
ALWAYS wear protective eyewear and appropriate  
clothing. If using a chemical injector , read and follow  
the chemical manufacturer  
recommendations on additional protective equipment,  
such as a respirator  
’s literature for  
.
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 HAVE 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 CAREFULLY. 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.

CAUTION  
Check the unit for any damage that may have occurred  
in shipping. Notify the carrier immediately if there is  
any damage.  
Before attaching to the water supply, check your  
local plumbing code regarding cross– connection  
to the water supply . A backflow preventer , P/N  
801–133, is available to prevent backflow of  
contaminated water into the fresh water supply .  
Install it upstream from the pump.  
Set Up  
Fill the battery cells with electrolyte and water. Charge  
the battery. Be sure the battery connections are correct  
and secure. Connect the fuel line to the engine using  
the quick coupler provided. Squeeze the priming bulb 3  
to 5 times. If you are using a downstream chemical  
injector, install it between the pump unloader and the  
high pressure hose, using the quick couplers provided.  
If inlet water pressure is over 60 psi (4.1 bar) a  
regulating water valve, P/N 800–258, must be  
installed at the garden hose connection.  
Do not exceed 160 _ F (70_ C) inlet water  
Connect the high pressure hose between the pump  
outlet and the gun inlet. Both of these connections are  
made with quick couplers.  
temperature.  
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.  
CAUTION  
Up to 100 ft (30 m) of high pressure hose may  
be used. Longer hoses may af

NOTE: The water source at the unit must have a  
minimum flow rate equal to that of the unit  
(see Technical Data, inside back cover).

STARTUP  
Always use this startup procedure to ensure that the  
If the engine is cold, completely close the engine  
choke. Press the start button. 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.  
unit is started safely and properly  
.
1. Check oil levels.  
Engine: Add SAE 30 or 10W–30 weight detergent  
oil as necessary  
.
If the engine is warm, leave the choke open or  
partially closed. Start the engine as described in the  
preceding paragraph. When the engine starts, be  
Pump: Add SAE 20 or 30 weight non–detergent oil  
or genuine CATr pump oil as necessary  
.
sure to open the choke completely  
.
NOTE: This pressure washer is 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.  
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.  
8. ALWAYS observe the following  
CAUTIONS to

avoid costly damage to the pressure washer  
.
WARNING  
CAUTION  
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.  
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.  
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.  
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 cables are pushed firmly onto the spark  
plugs. Put the ignition shutof f switch in the “on”  
position and the throttle in the “run” position.  
DO NOT pump caustic materials; such materials  
may corrode the pump components.  
9. See the chemical injector or sandblaster kit manual  
for detailed cleaning information if these  
accessories are used.  
6. Start the engine.  
NOTE: For easier starting, have one person start the  
pressure washer while another person  
triggers the spray gun.

tips. ALWAYS follow the procedure below  
.
1. Follow the Pressure Relief Procedure  
.
In the engaged position, the trigger safety latch  
prevents the gun from being triggered  
accidentally by hand or if it is dropped or bumped.  
Be sure the latch is pushed fully down when  
engaging it or it cannot prevent the gun from being  
triggered. See Figure 2.  
2. Point the gun and wand away from yourself and  
anyone else.  
3. Without holding your hand over the spray tip (A),  
pull back the quick coupler ring (B). Remove the old  
tip and/or install a new one, and then release the  
ring. See Figure 3.  
4. Be sure the tip is secure before starting to spray  
again.  
5. Tip holding holes are provided on the chassis.  
CAUTION  
To avoid blowing the o–ring out of the quick  
coupler, due to the high pressure in the system,  
never operate the pressure washer without a tip  
securely mounted in the quick coupler
