General Safety  
.
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.  
System Pressure  
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.  
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 manufacturers  
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  
chemical 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 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 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  
If you are using a downstream chemical injector, install it  
between the pump unloader and the high pressure  
hose, using the quick couplers provided.  
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.  
Connect the high pressure hose between the pump  
outlet and the gun inlet. Both of these connections are  
made with quick couplers.  
CAUTION  
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.  
Up to 100 ft (30 m) of high pressure hose may  
be used. Longer hoses may af

STARTUP  
Always use this startup procedure to ensure that the unit  
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.  
is started safely and properly  
.
1. Check oil levels.  
Engine: Add SAE 30 or 10W–30 weight detergent  
oil as necessary  
.
Pump: Add SAE 20 or 30 weight non–detergent oil  
as necessary  
.
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  
NOTE: Some units are equipped with a low–oil sensor  
that shuts the engine of f 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.  
open the choke completely  
.
CAUTION  
On recoil start engines, never let the starter rope  
return by itself. It could jam the recoil system.  
2. Check fuel level.  
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.  
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  
.
3. Turn on the water supply  
.
CAUTION  
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.  
Never run the unit dry. Costly damage to the pump  
will result. Always be sure the water supply is  
completely turned on before operating.  
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.  
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.  
On those units equipped with an ignition shutof  
f
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.  
6. Start the engine.  
NOTE: For easier starting, have one person start the  
pressure washer while another person triggers  
the spray gun.  
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 (2340 only).

Chemical Injector  
Trigger Safety Latch  
WARNING  
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.  
To reduce the risk of serious bodily injury  
including fluid injection, splashing in the eyes or  
on the skin, ALWAYS engage the trigger safety  
latch whenever spraying stops, even for a  
moment.  
,
WARNING  
Observe chemical manufacturer  
precautions regarding use of goggles, protective  
clothing or respirators.  
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.  
’s safety  
1026 & 1530: A downstream chemical injector is  
provided with the pressure washer. Insert the chemical  
strainer (attached with clear tubing to the chemical  
injector) into the container of chemical. Push the nozzle  
holder on the end of the wand away from the gun. This  
causes a drop in pressure that actuates the chemical  
injector. Pull the nozzle holder to deactivate the  
chemical injector and produce high pressure for rinsing.  
The flowrate of the chemical is regulated by turning the  
chemical adjuctment knob on the injector . Maximum  
chemical flow is at a full two turns counterclockwise from  
the closed (clockwise) position. T wisting the nozzle  
holder will change the spray fan angle.  
2340: The chemical injector is an accessory. See the  
chemical injector instruction manual.  
TRIGGER SAFETY LATCH SHOWN ENGAGED  
WARNING  
DO NOT attempt to open or close the adjustable  
nozzle when the spray gun is in use. Be sure that  
the trigger safety latch on the gun is in the ”ON”  
position before adjusting to avoid serious bodily  
injury or fluid injection.  
Check the distance that you will need to hold the spray  
nozzle from the surface by test spraying on a scrap of  
similar material. For soft surfaces, such as wook, hold  
nozzle 3 ft (1 m) from the surface and gradually bring it  
closer, checking to see if the high pressure spray is  
damaging the surface.  
TRIGGER SAFETY LATCH SHOWN  
DISENGAGED  
Figure 2  
Mist the wet surface with cleaning solution. Let it soak  
briefly, then use the high pressure rinse to ”chisel” off the  
soil. Keep the nozzle at an angle to the surface and at a  
distance determined to be best for the surface. If some  
soil remains, repeat the procedure, letting the chemical  
soak a little longer . Stubborn soil can be cleaned of f  
better with a stronger, heated cleaning solution.  
Protect surfaces that might be damaged by the cleaning  
solution or the high pressure spray. Rinse the solution  
before it dries.

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 dif ferent 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.  
2. Carefully separate the manifold from the crankcase.  
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.  
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.
