OPERATION INSTRUCTIONS
BEFORE OPERATION
ADD ENGINE OIL
Place pressure washer on a flat, level surface.
Clean area around oil fill and remove yellow
oil fill cap. Using oil funnel (optional), slowly
pour contents of provided oil bottle into oil fill
opening. Replace oil fill cap and fully tighten.
NOTE: Improper treatment of pressure washer
can damage it and shorten its life. DO NOT at-
tempt to crank or start the engine before it has
been properly serviced with the recommended
oil. This may result in an engine failure.
ADDING FUEL
WARNING: Failure to use fuel as recom-
mended in this manual will void the warranty.
· DO NOT use unapproved gasoline such as E85
(85% ethanol/15% gasoline).
· DO NOT mix oil with gasoline.
· DO NOT modify engine to run on alternate
fuels. Mix in a fuel stabilizer when adding fuel
to pressure washer (at least 1 time every 6
months) to protect fuel system from forming
gum deposits. The engine is certified to run on
gasoline.
WARNING: Fuel and fuel vapor are ex-
tremely flammable and explosive. Fire or ex-
plosion from misuse of fuel can cause severe
burns and even death.
WHEN ADDING FUEL TO PRESSURE WASHER,
OBSERVE THE FOLLOWING STEPS:
· Turn pressure washer
OFF and let it cool for
at least two minutes
before removing fuel
cap. Loosen fuel cap
slowly to release pres-
sure.
· Fill fuel tank outdoors.
· DO NOT overfill fuel
tank. Leave room for
fuel to expand.
· Wait for spilled fuel to evaporate before
cranking engine.
· Keep fuel away from sparks, open flames, pi-
lot lights, heat and other ignition sources.
· DO NOT light a cigarette or smoke near open
fuel tank or container.
· Clean area around fuel fill cap and slowly re-
move cap to allow any pressure to escape.
· Slowly add unleaded
gasoline (A) to fuel
tank (B). Use extreme
caution not to fill fuel
above baffle (C). This
will allow appropriate space for fuel expansion.
· Install fuel cap and allow any spilled fuel to
evaporate before starting engine.
CONNECT HOSE AND WATER SUPPLY TO PUMP
· Similarly, attach oth-
er end of high pres-
sure hose to high pres-
sure outlet on pump.
Connect one end of
the pressure hose to
pump outlet and se-
cure the plastic nut.
Pull on hose to be sure of tight connection.
· Before connecting garden hose to water inlet,
inspect inlet screen. Clean screen if it contains
debris or have it replaced if damaged. DO NOT
run pressure washer if inlet screen is damaged.
· Run water through your garden hose for 30
seconds to clean out any debris.
IMPORTANT: DO NOT siphon standing wa-
ter for the water supply. Use ONLY cold water
(less than 37º C).
