4. Replace spark plug if electrodes are pitted, burned or
porcelain is cracked. Use the recommended
replacement plug. See Specifications.
5. Install spark plug and tighten firmly.
Spark Arrester Service
Your engine is not factory-equipped with a spark arrester. In
some areas, it is illegal to operate an engine without a spark
arrester. Check local laws and regulations. A spark arrester is
available from your nearest qualified service center.The spark
arrester must be serviced every 50 hours to keep it
functioning as designed.
If the engine has been running, the muffler will be very hot.
Allow the muffler to cool before servicing spark arrester.
• Remove spark arrester screen for cleaning and
inspection.
• Replace if screen is damaged.
Air Cooling System
Over time debris may accumulate in cylinder cooling fins and
cannot be observed without partial engine disassembly. For
this reason, we recommend you have a qualified service
dealer clean the cooling system (A) per recommended
intervals (see Maintenance Schedule in beginning of
Maintenance section). Equally important is to keep top of
engine free from debris. See Clean Debris.
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. 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.
2. 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.
3. Empty pump of all pumped liquids by pulling recoil
handle about six times. This should remove most liquid
in pump.
4. Store unit in a clean, dry area.
5. If storing for more than 30 days, see Long Term
Storage on next page.
WARNING
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or
death.
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 can ignite fuel vapors.
WARNING
Contact with muffler area can result in serious
burns.
Exhaust heat/gases can ignite combustibles,
structures or damage fuel tank causing a fire.
• DO NOT touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 5 feet (1.5 m) of clearance on all sides of pressure
washer including overhead.
• Code of Federal Regulation (CFR) Title 36 Parks, Forests, and
Public Property require equipment powered by an internal
combustion engine to have a spark arrester, maintained in
effective working order, complying to USDA Forest service
standard 5100-1C or later revision. In the State of California a
spark arrester is required under section 4442 of the California
Public resources code. Other states may have similar laws.
WARNING
The high pressure stream of water that this
equipment produces can cut through skin and its
underlying tissues, leading to serious injury and
possible amputation.
Spray gun traps high water pressure, even when
engine is stopped and water is disconnected,
which can cause 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.
