Engine Maintenance
See the engine operator's manual for instructions on
how to properly maintain the engine.
CAUTION Avoid prolonged or repeated skin
contact with used motor oil.
• Used motor oil has been shown to cause skin cancer in
certain laboratory animals.
• Thoroughly wash exposed areas with soap and water.
KEEP OUT OF REACH OF CHILDREN.
DON'T POLLUTE. CONSERVE
RESOURCES. RETURN USED OIL TO
COLLECTION CENTERS.
Inspect Muffler and Spark Arrester
Inspect the muffler for cracks, corrosion, or other
damage. Remove the spark arrester, if equipped, and
inspect for damage or carbon blockage. If replacement
parts are required, make sure to use only original
equipment replacement parts.
WARNING Exhaust heat/gases could ignite
combustibles, structures or damage
fuel tank causing a fire, resulting in
death or serious injury.
Contact with muffler area could cause burns
resulting in serious injury.
• DO NOT touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 5 ft. (1.5 m) of clearance on all sides of
pressure washer including overhead.
• It is a violation of California Public Resource Code,
Section 4442, to use or operate the engine on any forest-
covered, brush-covered, or grass-covered land unless
the exhaust system is equipped with a spark arrester, as
defined in Section 4442, maintained in effective working
order. Other states or federal jurisdictions may have
similar laws.
Contact the original equipment manufacturer, retailer,
or dealer to obtain a spark arrester designed for the
exhaust system installed on this engine.
• Replacement parts must be the same and installed in the
same position as the original parts.
After Each Use
Water should not remain in the unit for long periods
of time. Sediments or minerals can deposit on pump
parts and freeze pump action. Follow these procedures
after every use:
1. Flush detergent system by turning its detergent
shut-off valve to OFF (0) position and run pressure
washer with black spray tip. Flush for one to two
minutes.
WARNING The high pressure stream of water
that this equipment produces could cut
through skin and its underlying tissues,
resulting in serious injury and possible
amputation.
Spray gun traps high water pressure, even when
engine is stopped and water is disconnected, which
could result in serious injury.
• Keep high pressure hose connected to pump and spray
gun while system is pressurized.
• ALWAYS point spray gun in safe direction, press red
button and squeeze spray gun trigger to release high
pressure, every time you stop engine.
2. Shut off engine, turn off water supply, point gun
in a safe direction, press red button and squeeze
trigger to relieve trapped pressure, and let engine
cool.
3. Disconnect hose from spray gun and high
pressure outlet on pump. Drain water from hose,
gun, and nozzle extension. Use a rag to wipe off
the hose.
4. Place the spray gun and nozzle extension in the
accessory tray. Hang high pressure hose on hook.
5. Empty pump of all pumped liquids by pulling recoil
handle about six times. This should remove most
liquid in pump.
6. Store unit in a clean, dry area.
7. If storing for more than 30 days, see Long Term
Storage on next page.
WARNING Fuel and its vapors are extremely
flammable and explosive which could
cause burns, fire or explosion resulting
in death or serious injury.
WHEN STORING FUEL OR EQUIPMENT WITH FUEL
IN TANK
• Store away from furnaces, stoves, water heaters, clothes
dryers, or other appliances that have pilot light or other
ignition source because they could ignite fuel vapors.
