PRESSURE WASHER MAINTENANCE
Check and Clean Inlet Screen: Remove quick-con­
nect and examine inlet screen on the female connec­
tor. Clean if it is clogged or replace if it is torn.
Check High Pressure Hose: High pressure hose
can develop leaks from wear, kinking, abuse. Inspect
hose each time before using it. Check for cuts, leaks,
abrasions or bulging of cover, or damage or move­
ment of couplings. If any of these conditions exist,
replace hose immediately.
▲ DANGER: Water spraying from a leak is
capable of injecting material into skin.
NEVER repair high pressure hose.
Replace with hose №at meets minimum
^ pressure rating of your pressure washer.
Check Detergent Hose: Examine the filter on the
detergent hose and clean if clogged. Hose should fit
tightly on barbed fitting. Examine hose for leaks or
tears. Replace the filter or hose if either is damaged.
Check Gun and Wand: Examine hose connection to
gun and make sure it is secure. Test trigger by press­
ing it and making sure it springs back into place when
you release it. Put safety latch in UP position and test
trigger. You should not be able to press trigger.

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 main­
tained.
CHANGING ENGINE OIL
Change engine oil every 25 hours. 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 run­
ning, as follows:
• Before you tip the pressure washer to drain oil,
drain fuel tank by running pressure washer until
fuel tank is empty.
• Clean area around oil fill, remove oil fill cap/dip-
stick. Wipe dipstick clean.
• Tip your pressure washer to drain oil completely
from the oil fill tube into a suitable container.
When crankcase is empty, return the pressure
washer to upright position.
• Fill engine crankcase with recommended oil until
oil level is at FULL point on dipstick. Do not over­
fill above that mark. POUR SLOWLY.
• When engine crankcase is filled to proper level,
install and tighten oil cap/dipstick.
SERVICE AIR CLEANER
Your engine will not run properly and may be dam­
aged if you run it with a dirty air cleaner.
Clean or replace the air cleaner once every 25 hours
of operation or once each year, whichever comes
first. Clean or replace more often if operating under
dirty or dusty conditions. Replacements are available
at your local Sears Authorized Service Center.
To clean or replace the air cleaner, follow these
steps:
• Remove screw on the air cleaner cover.
• Remove air cleaner carefully to prevent debris
from falling into carburetor.
• Take air cleaner apart and clean all parts and ser­
vice the foam element.
• Wash foam element in liquid detergent and water.
If the element is damaged or very dirty, replace
the element.
• Squeeze the element dry in a clean cloth.
• Saturate the foam element in engine oil. Squeeze
the saturated element in a clean cloth to remove
excess oil.
• Reassemble all parts and fasten securely to the
carburetor with the screw.
