PUMP OIL MAINTENANCE
Changing Pump Oil
Change oil after first 50 hours of operation and
then every 200 hours or 3 months, whichever
occurs first.
NOTE: When changing pump oil, use only high
quality non-detergent 30 weight oil. Use no
special additives.
Change pump oil as follows:
1. Clean area around brass oil drain plug at
bottom of pump.
2. Remove oil drain plug. Drain oil completely
into an approved container.
3. When oil has completely drained, install oil
drain plug and tighten firmly.
4. Clean area around pump oil dipstick. Re-
move dipstick and fill pump with recommend-
ed oil to full mark on dipstick.
5. Install pump oil dipstick.
6. Wipe up any spilled oil.
Engine Maintenance
See the engine operator’s manual for instruc-
tions on how to properly maintain the engine.
WARNING: Avoid prolonged or repeated
skin contact with used motor oil. Used motor
oil has been shown to cause skin cancer in cer-
tain laboratory animals. Thoroughly wash ex-
posed areas with soap and water.
STORAGE
Long Term Storage Instructions (Fuel in tank)
Gasoline fuel can become stale when stored
over 30 days. Stale fuel causes acid and gum
deposits to form in the fuel system or crucial
carburetor parts. To keep fuel fresh, add a fuel
stabilizer liquid additive to fuel. The fuel stabi-
lizer is available at most auto parts stores.
Draining gasoline is unnecessary if the fuel sta-
bilizer is used according to the instructions that
come with it.
Run pressure washer engine for a minimum of
two minutes, after stabilizer is added to fuel,
to allow it to circulate throughout the engine.
The engine and fuel can be stored up to 24
months.
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.
To Protect Against Rust Formation During Stor-
age, Oil the Cylinder Bore:
1. Remove spark plug and pour approximately
1/2oz (15 ml) of clean engine oil into the cyl-
inder.
2. Install spark plug and pull starter handle
slowly to distribute oil. DO NOT start engine
at this time.
3. Slowly pull the recoil starter 2 to 3 times to
distribute and coat the cylinder bore with oil.
WARNING: Unintentional sparking can
cause fire or electrical shock. Failure to observe
this warning can cause severe property dam-
age, severe burns and even death.
Disconnect spark plug wire from spark plug
and cover tip of spark plug wire with insulat-
ing tape and place wire where it cannot come
in contact with spark plug or pressure washer
frame.
Storage of Pressure Pump
1. Drain all water from high pressure line, coil
it and store it in cradle of pressure washer
handle.
2. Drain all water from spray gun and spray
wand by holding spray gun in vertical position
with nozzle pointed downward. Squeeze trig-
ger to remove fluids from spray gun and spray
wand. Store in spray gun/hose holder.
3. Store chemical hose, high pressure hose and
spray wand so they are protected from dam-
age, such as being run over.
It is RECOMMENDED that you follow these
steps to protect the internal seals of pressure
washer when storing unit for more than 30
days and/or when freezing temperatures are
expected.
1. Obtain a funnel, six ounces of RV antifreeze
and approximately 36 inches of garden hose
with a male hose connector on one end.
CAUTION: Use only RV antifreeze. Any oth-
er type of antifreeze is corrosive and can dam-
age pressure pump.
2. Disconnect spark plug wire. Ensure it cannot
touch any metal on pressure washer.
3. Connect 36 inch length of garden hose to
water inlet of pressure pump.
4. Add RV antifreeze.
5. Pull engine starter rope slowly several times
until antifreeze comes out of pressure hose
connection of pressure pump.
