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 this pressure  
washer.  
CHECK all spray equipment regularly and repair or  
replace worn or damaged parts immediately  
.
ALWAYS wear protective eyewear and appropriate  
clothing. If using a chemical injector, read and follow the  
chemical  
recommendations on additional protective equipment,  
such as a respirator  
manufacturer’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.  
temperatures above 200_ F (93_ C) or below –40_  
F
(–40_ C).  
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 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.

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  
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.  
Connect the high pressure hose between the pump  
outlet and the gun inlet. Both of these connections are  
made with quick couplers.

PUMP SERVICE  
Servicing the Plungers  
WARNING  
To reduce the risk of serious bodily injury,  
including fluid injection, splashing in the eyes or  
on the skin, or injury from moving parts, always  
follow the Pressure Relief Procedure  
Warning before proceeding.  
NOTE: Plunger repair kit, P/N 801–474 is available to  
replace retainers, o–rings, washers and  
backup rings for three cylinders.  
1. Loosen the plunger retaining screw five to six turns,  
using an M10 wrench. Push the plunger towards the  
crankcase to separate the plunger and retaining  
screw.  
NOTE: The following metric wrenches are needed:  
M10, M13 and M30. Repair kits are available.  
Refer to the individual repair sections and the  
pump parts page for more details. For the best  
results, use all parts in the kits.  
2. Remove the screw from the plunger and examine  
the o–ring, backup ring and copper bearing/gasket  
washer. Replace these parts, if necessary, using kit  
801–474.  
NOTE: There are two different tool kits to aid in  
servicing the pump. P/N 800–298 is used to  
ease installation of packings. P/N 800–271  
includes the items in 800–298 and tools to aid  
in the removal of packing retainers.  
3. Remove the plunger and flinger from the plunger  
shaft. Clean, examine and replace parts as  
necessary.  
4. Inspect the plunger shaft for oil leakage from the  
crankcase. If leaking is obvious, replace the oil  
seals. Otherwise, DO NOT remove these seals as  
they cannot be reused. An oil seal kit is available to  
replace the seals.  
Valves  
NOTE: For a set of six valves, order P/N 801–472.  
1. Remove the hex plug from the manifold using an  
M30 wrench.  
5. Lightly grease the flinger and oil seal, if it is being  
replaced and replace them on the plunger shaft.  
2. Examine the o–ring under the hex plug and replace  
it if it is cut or distorted.  
Then install the plunger  
.
6. Lightly grease the retaining screw and the outer end  
of the plunger. Place the washer, o–ring and backup  
ring around the screw and install the screw through  
the plunger. Torque to 14.4 ft–lb (19.5 Nm).  
3. Remove the valve assembly from the cavity; the  
assembly may come apart.  
4. Install the new valve. Install the o–ring and hex plug;  
torque to 75 ft–lb (103 Nm).  
NOTE: If you plan to replace the packings, refer to  
Servicing the V–Packings.  
NOTE: Retorque the plug after 5 hours of operation.  
7. Lubricate the outside of each plunger. Slide the  
manifold onto the crankcase, being careful not to  
damage the seals.  
Pumping Section  
1. Remove the eight capscrews and lockwashers from  
the manifold using an M13 wrench.  
8. Install the capscrews and washers finger–tight.  
Torque the screws to 21.7 ft–lb (29 Nm) following  
the tightening pattern (Figure 4). Uneven tightening  
may cause the manifold to bind or jam.  
2. Carefully separate the manifold from the crankcase.  
NOTE: It may be necessary to tap the manifold lightly  
with a soft mallet to loosen.  
CAUTION  
Keep the manifold properly aligned with the  
ceramic plungers when removing to avoid  
damage to the plunger or seals.

5. Thoroughly clean the packing cavities and examine  
for debris and damage.  
Servicing the V–Packings  
NOTE: There are two types of packing kits: one is just  
packings only, the other includes the  
packings, rings and retainers.  
6. Lightly grease the packing cavities and then replace  
the packings in the following order: head ring,  
v–packing, intermediate ring, head ring, v–packing  
and packing retainer with the o–ring installed in the  
retainer groove.  
1. Remove the manifold as outlined in the Pumping  
Section.  
2. Carefully pull the packing retainer from the  
manifold. Examine the o–ring and replace it if it is cut  
or damaged.  
CAUTION  
Install the parts in the proper order and facing  
the correct direction. Improperly installed parts  
will cause a malfunction.  
3. Remove the v–packing and head ring. Pull out the  
intermediate retainer ring. Remove the second  
v–packing and second head ring.  
7. Reassemble the manifold as instructed in Servicing  
the Plungers.  
4. Inspect all parts and replace as necessary
