PRESSURE WASHER MAINTENANCE
Check and Clean inlet Screen: Remove quick-connect

Clean if it is clogged or replace if it is torn.
Check High Pressure Hose: High pressure hose can
develop leaks from wear, kinking, atHise. Inspect hose
each time before using it. Check for cuts, leaks, abra­
sions or bulging of cover, or damage or movement of
couplings. If any of these conditions exist, replace hose
immediately.
A
DANGER: Water spraying from a leak is
capable of injecting material into skin.
NEVER repair high pressure hose. Replace
with hose that meets minimum pressure rat­
ing of your pressure washer.
Check Detergent Hose: Examine the filter on the deter­
gent 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.

gun and make sure it is secure. Test trigger by pressing
it and making sure it springs back into place when you
release it. Put safety latch in ON position and test trig­
ger. You should not be able to press trigger.

ENGINE MAINTENANCE
A CAUTION: Disconnect spark plug wire from

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 ENGINE OIL
Change oil after first 8 hours of operation. Change oil
every 50 hours thereafter. If you are using your pressure
wrasher 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:
• 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/dipstick.
Wipe dipstick clean.
• Tip your pressure washer as shown to drain oil com-
plelety into a suitable container. When crankcase is
empty, return the pressure washer to its upright posi­
tion.
Fill engine crankcase with recommended oil until oil
level is at FULL point on dipstick. Do not overfill
above that mark. About 20 ounces is required. POUR
SLOWLY. _
When engine crankcase is filled to proper level,
install and tighten oil cap/dipstick.
