Air Filter Maintenance:
1. Remove the Air Filter Cover and the air
filter(s) and check for dirt. Clean as
described below.
2. Cleaning:
• For paper filters: To prevent injury from
dust and debris, wear ANSI-approved safety
goggles, NIOSH-approved dust
mask/respirator, and heavy-duty work
gloves. In a well-ventilated area away from
bystanders, use pressurized air to blow
dust out of the filter. If this does not get the
filter clean, replace it.
• For foam filters: Wash the filter in warm
water and mild detergent several times.
Rinse. Squeeze out excess water and allow
it to dry completely. Soak the filter in
lightweight oil briefly, then squeeze out the
excess oil.
3. Install the cleaned filter(s). Secure the Air
Filter Cover before use.
Long-term Storage
When the equipment is to remain idle for
longer than 20 days, prepare the Engine
for storage as follows:
1. Cleaning. Wait for Engine to cool, then
clean Engine with dry cloth.
WARNING: Fire / Explosion
Hazard
Fuel and its vapors are
extremely flammable and
explosive which could cause burns, fire
or explosion resulting in death or serious
injury. Fill tank only in a well-ventilated
area away from ignition sources. If the
engine is hot from use, shut down and
wait for it to cool before adding fuel. Do
not smoke, or have open flame near fuel,
or area when refueling.
1. Fuel. Gasoline fuel can become stale
when stored over 30 days, which
will cause acid and gum deposits
to form in the fuel system or crucial
carburetor parts. To keep fuel fresh, add
fuel stabilizer to the fuel tank. Draining
gasoline is unnecessary if the fuel
stabilizer is used according to the
instructions that come with it. Run Pressure
Washer engine for a minimum of five
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.
NOTICE: Be sure to have the water connected
to the pump when running the engine for any
purpose.
Lubrication:
1. To protect against rust formation during
storage, oil the cylinder bore:
2. Change engine oil.
3. Clean out area around spark plug.
Remove spark plug and pour approximately
1/2 oz (15 ml) of clean engine oil into cylinder
through spark.
4. Replace spark plug, but leave spark plug
cap disconnected.
5. Pull Starter Handle to distribute oil in cylinder.
Stop after one or two
revolutions when you feel the piston start the
compression stroke (when you start to feel
resistance).
Disconnect spark plug wire from spark plug
and cover tip of spark plug wire with insulating
tape and place wire where it cannot come in
contact with spark plug or Pressure Washer
frame.
WARNING: Fire / Electrical Shock
Unintentional sparking can
cause fire or electrical shock.
Failure to observe this
warning can cause severe property
damage, severe burns and even death.
