SERVICING THE AIR CLEANER
Your engine will not run properly and may be damaged
if you run it with a dirty air cleaner.
Replace 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 Authorized Service Center.
Important: Operating your pressure washer without
a complete air cleaner installed will allow dirt to enter
the engine, causing rapid engine wear. This type of
damage is not covered by warranty.
To clean or replace the air cleaner, follow these
steps:
• Press the latch tabs on fuel tank side of air cleaner
cover, and remove cover. Check filter to be sure it is
clean and in good condition.

Replace the filter if it is damaged.
If filter is dirty, clean it by tapping it several times
on a hard surface to remove any dirt. You may also
blow compressed air [(not exceeding 30 psi (207 kPa,
2.1 kg/cm"}] through the filter from the clean side that
faces the engine.
Never try to brush off dirt. Brushing will force dirt into
the filter fibers.
Wipe dirt from the air cleaner body and cover, using
a moist rag. Be careful to prevent dirt from entering
the air duct that leads to the carburetor.
insert a new or cleaned filter.
Replace cover. Push tabs into slots until they “click”.
CLEAN/REPLACE 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. Replace with
NGK: BPR6ES or equivalent type spark plug.
• Disconnect the spark plug cap and remove any dirt
from around the spark plug area.
• Remove the spark plug with a 13/16-inch spark plug
wrench.
• Inspect spark plug and replace if electrodes are worn
or if the insulator is cracked or chipped.
• Clean with a wire brush if you are going to reuse it.
• Measure the spark plug electrode gap with a suitable
gauge. Correct the gap, if necessary, by carefully
bending the side electrode. Set gap at 0.028-0.031 in,
(0.70-0.80mm).
• Install spark plug carefully, by hand, to avoid cross­
threading. Tighten with spark plug wrench to com­
press the washer. (Used plug -1/8 to 1/4 turn; New
plug -1/2 turn)
• Attach the spark plug cap.
NOZZLE MAINTENANCE
if the nozzle becomes restricted or clogged with foreign
materials, such as dirt, excessive pump pressure may
develop. A partially clogged nozzle can cause a pulsing
sensation during use. This generally is not pump related,
but rather due to a clogged or partially restricted nozzle.
If you feel this pulsing during use, it is recommended you
immediately clean the nozzle. Use the kit included with
your pressure washer, and follow these instructions:
• Shut off engine and turn off the water supply.
• Separate the nozzle from the nozzle extension.
• Rotate to the stream setting.
• Remove orifice from the end of the nozzle using the
alien wrench included with the kit or with a 2mm or
5/64 alien wrench.
