long
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).

Operation
Pressure Relief Procedure

WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
spraying accidentally. To reduce the risk
of an injury from accidental spray from the gun,
splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:
D
D
D
D

are instructed to relieve the pressure,
stop spraying for more than 10 minutes,
check or service any of the system equipment,
or install or clean the spray nozzle.

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.

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.

WARNING
FIRE HAZARD
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.

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.

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.

824–001

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 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. 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.

824–001

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 cleaning information if this accessory is used.

The SHERWIN–WILLIAMS Warranty
and Disclaimers
WARRANTY
Graco warrants all equipment manufactured by it 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. As purchaser’s sole remedy for breach of this
warranty, Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment proven 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, any malfunction, damage or wear caused by faulty installation,
misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of
non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility with Graco
equipment of 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 claim. 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.
DISCLAIMERS AND LIMITATIONS
The terms of this warranty constitute purchaser’s sole and exclusive remedy and are in lieu of any other warranties (express or
implied), including warranty of merchantability or warranty of fitness for a particular purpose, and of any non–contractual
liabilities, including product liabilities, based on negligence or strict liability. Every form of liability for direct, special or consequential damages or loss is expressly excluded and denied. In no case shall Graco’s liability exceed the amount of the purchase price.
Any action for breach of warranty must be brought within two (2) years of the date of sale.
EQUIPMENT NOT COVERED BY GRACO WARRANTY
Graco makes no warranty, and disclaims all implied warranties of merchantability and fitness for a particular purpose, with
respect to accessories, equipment, materials, or components sold but not manufactured by Graco. These items sold, but not
manufactured by Graco (such as electric motor, switches, hose, etc.) are subject to the warranty, if any, of their manufacturer.
Graco will provide purchaser with reasonable assistance in making any claim for breach of these warranties.
