ENGINE MAINTENANCE
Checking Oil Level
Oil level should be checked prior to each use or at
least every 5 hours of operation. Keep oil level
maintained.
Changing Oil
Change engine oil after the first 2 hours and every 25
hours thereafter. If you are using your pressure
washer under extremely dirty or dusty conditions, or in
extremely hot weather, change oil more often.
Change oil while engine is still warm from running, as
follows:
• Drain fuel tank by running pressure washer until
fuel tank is empty.
• Clean area around oil fill, remove oil fill
cap/dipstick. Wipe dipstick clean.
• Tip your pressure washer to drain oil from the oil fill
into a suitable container making sure you tip your
unit away from the spark plug. When crankcase is
empty, return the pressure washer to upright
position.
• Wipe dipstick clean, insert it into oil fill hole and
tighten securely, remove dipstick. Add
recommended oil up to "Full" mark on dipstick.
Pour slowly. Wipe dipstick clean each time oil level
is checked. Do Not overfill.
• Install oil fill plug and dipstick, tighten securely.
• Wipe up any remaining oil.
Service Air Cleaner
Your engine will not run properly and may be
damaged if you run it with a dirty air cleaner.
Replace the air cleaner once every 100 hours of
operation or once each year, whichever comes first.
Replace more often if operating under dirty or dusty
conditions. Replacements are available at your local
Sears service center.
To replace the air cleaner, follow these steps:
• Remove cover by pulling tab away from body while
lifting cover upward.
• Remove dirty air filter element carefully to prevent
debris from falling into carburetor. Discard.
• Clean inside of cover and body thoroughly.
• Install new air filter elements in body. You can
purchase new air filter elements by calling
1-800-366-PART.
• Install cover by hooking slot of cover over tab on
body. Push cover down, snapping cover onto body.
Service Spark Plug
Service the spark plug every 100 hours of operation or
yearly, whichever occurs first.
_ CAUTION: Disconnect spark plug wire from
spark plug and keep wire away from spark plug
while servicing engine.
• Clean area around spark plug.
• Remove and inspect spark plug.
• Replace spark plug if the electrodes are worn, or if
the insulator is cracked or chipped. For
replacement use Champion RJ-19LM.
• Check electrode gap with wire feeler gauge and set
gap at 0.030 inches (0.76mm), if necessary.
• Install spark plug, tighten securely.
Carburetor
If you think your carburetor needs adjusting, see your
nearest Sears service center. Engine performance
may be affected at altitudes above 7000 feet. For
operation at higher elevations, contact your nearest
Sears service center.
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:
• Flush detergent siphoning tube by placing the filter
into a pail of clean water while running pressure
washer in low pressure mode (adjustable nozzle in
the forward position). Flush for one to two minutes.
• Shut off the engine and let it cool, then remove all
hoses.
• Disconnect spark plug wire from spark plug.
• Empty the pump of all liquids by pulling recoil
handle about 6 times. This should remove most of
the liquid in the pump.
