Operation
Pressure Relief Procedure
WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
Dare instructed to relieve the pressure,
Dstop spraying for more than 10 minutes,
Dcheck or service any of the system equipment,
Dor install or clean the spray nozzle.
Pressure Relief Procedure
1. Engage the trigger safety latch.
2. Turn the sprayer off.
3. Remove the ignition cable from the spark plug.
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.
Startup
Always use this start–up procedure to ensure that the
unit is started safely and properly.
1. Check oil levels:
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.
2. Check fuel level.
WARNING
FIRE HAZARD
Do not refuel a hot engine. Refueling a
hot engine could cause a fire. Use only
fresh, clean regular or unleaded gaso-
line. Close the fuel shutoff valve during refueling.
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.

6824111
Operation
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.
Put the switch in the “on”position and put the
throttle in the “run”position.
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.
CAUTION
Do not allow the starter rope to snap back against
the engine. Return it gently to prevent damage to
the recoil.
6. Start the engine.
NOTE: For easier starting, have one person start the
pressure washer while another person triggers
the spray gun.
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.
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.
8. Always observe the following CAUTIONS to avoid
costly damage to the pressure washer.
9. See the sandblaster kit manual for detailed clean-
ing information if this accessory is used.

Operation
Trigger Safety Latch
WARNING
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.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.

TRIGGER SAFETY LATCH
Chemical Injector Operation
WARNING
To reduce the risk of serious bodily injury, including
fluid injection or splashing in the eyes or onto the
skin, use extreme caution when changing spray
tips. always follow the procedure below.
1. Follow the Pressure Relief Procedure.
2. Insert the chemical filter (attached with clear tubing
to the chemical injector) into the container of
chemical.
3. Install the black large orifice chemical tip (see
Installing and Changing Tips).
This causes a drop in pressure that actuates the
chemical injector. Changing back to a small diameter
spray tip deactivates the chemical injector and pro-
duces high pressure for rinsing. The chemical filter can
be left in the chemical container during high pressure
use. The flow rate of the chemical may be regulated+
by turning the chemical adjustment knob on the injec-
tor. Maximum chemical flow is a full two turns counter-
clockwise from the closed (clockwise) position.
Installing and Changing Spray Tips
WARNING
To reduce the risk of serious bodily injury, including
fluid injection or splashing in the eyes or onto the
skin, use extreme caution when changing spray
tips. always follow the procedure below.
1. Follow the Pressure Relief Procedure.
2. Point the gun and wand away from yourself and
anyone else.
3. Spray tips have a 4–or 5–digit number on them.
The first two digits are the spray angle. Select the
spray tip appropriate for your application.
Spray Tip Number Spray Pattern Fan Angle
00XXX 0_, blaster (red)
15XXX 15_(yellow)
25XXX 25_(green)
40XXX 40_(white)
NOTE: The chemical injector tip is brass, has a large
opening and a black plastic cap.
4. Without holding your hand over the spray tip (A),
pull back the quick coupler ring (B). Remove the
current tip and/or install a different one, and then
push back the ring. See Figure 3.
5. Pull on the tip to be sure the tip is secure before
starting to spray again.
6. 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.

Sherwin-Williams Standard Warranty
Graco warrants all equipment referenced in this document which is manufactured by Graco 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. With the
exception of any special, extended, or limited warranty published by Graco, Graco will, for a period of twelve months from the date of
sale, repair or replace any part of the equipment determined by Graco to be defective. This warranty applies only when the equipment
is installed, operated and maintained in accordance with Graco’s written recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by
faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or sub-
stitution of non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of
Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,
installation, 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 claimed defect. 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.
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT
NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other
remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any
other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the
date of sale.

A PARTICULAR PURPOSE, IN CONNECTION WITH ACCESSORIES, EQUIPMENT, MATERIALS OR COMPONENTS SOLD
BUT NOT MANUFACTURED BY GRACO. These items sold, but not manufactured by Graco (such as electric motors, switches,
hose, etc.), are subject to the warranty, if any, of their manufacturer. Graco will provide purchaser with reasonable assistance in mak-
ing any claim for breach of these warranties.
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment
hereunder, or the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract,
breach of warranty, the negligence of Graco, or otherwise.
