Service Spark Plug
Change the spark plug every 100 hours of operation or once
each year, whichever comes first. This will help your engine
to start easier and run better.
1. Clean area around spark plug.
2. Remove and inspect spark plug.
3. Check electrode gap with wire feeler gauge and set
spark plug gap to .030 inch (.76 mm) if necessary.
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.
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.
• 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 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.
Keep areas within heavy line clear of debris.
Clean Combustion Chamber
We recommend you have a qualified service dealer remove
combustion deposits from the cylinder, cylinder head, top of
piston and around valves per recommended intervals (see
Maintenance Schedule in beginning of Maintenance section).
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. 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.
2. Place the spray gun, nozzle extension, floor brush,
utility brush, brush extension and high pressure hose in
the accessory storage bag.
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.
