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 5 hours and every
50 hours or annually thereafter. If you are using your
pressure washer under extremely dirty or dusty
conditions, or in extremely hot weather, change oil
every 25 hours.
Change oil while engine is still warm from running, as
follows:
• Remove drain plug from the bottom of engine.
• Drain oil into a suitable container. When crankcase
is empty, replace drain plug in engine.
• Slowly pour oil into oil fill opening. Replace and
tighten dipstick, remove and check oil level. Oil
level should be at "Full" mark on dipstick. Do Not
overfill above that mark.
• When engine crankcase is filled to proper level,
install and tighten oil cap/dipstick.
• 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.
Service the air cleaner once every 100 hours of
operation or once each year, whichever comes first.
Service more often if operating under dirty or dusty
conditions. Replacements are available at your local
Sears service center.
To service the air cleaner, follow these steps:
• Remove screws and lift cover.
• Carefully remove pre-cleaner and cartridge
assembly.
• After servicing pre-cleaner and cartridge, assemble
pre-cleaner on cartridge.
• Install pre-cleaner/cartridge in base.
• Place cover on air cleaner and tighten screws
securely to base.
Replace Spark Plug
Replace the spark plug yearly or every 100 hours of
operation.
,_ CAUTION: Disconnect spark plug wire from
spark plug and keep wire away from spark plug.
• Clean area around spark plug and remove.
• For replacement use Champion RJ19LM or
equivalent.
• 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 4000 feet. For
operation at higher elevations, contact your nearest
Sears service center.
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 Sears service center. For the part number call
1-800-366-PART.
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 the
spark arrester.
• Remove spark arrester screen for cleaning and
inspection.
• Replace if screen is damaged.
