OPERATING INSTRUCTIONS
1. Read all manuals provided with this pressure washer.
Become familiar with location and function of all op-
erating and safety controls.
WARNING: Check hoses, fittings, wand, trigger gun
and fuel connections daily for signs of wear, cracks
and looseness, and replace as required.
2. Connect water supply hose to the garden hose con-
nector located on pump. The water faucet and sup-
ply hose must be capable of providing a minimum of
3.0 gallons per minute.
WARNING: Do not fill engine fuel tank while engine
is running or hot. Let engine cool before refueling
or spontaneous fire may result. Fuel spillage or va-
pors could ignite if engine is hot.
3. Fill the engine fuel tank. It may be necessary to use
a funnel or long spout to clear the chassis if filling
with a gas can. Do not overfill, fill to the bottom of
filler neck only. Use lead free gasoline minimum 86
octane. Do not use gasoline containing more than
5% methanol, 10% ethanol or 15% MTBE. Refer
to the provided gasoline engine manual for additional
details.
4. Check pump and engine oil levels.
IMPORTANT: Before installing pressure nozzle on
initial start-up, turn on the water supply and allow
water to run from the end of the wand until clear to
prevent the nozzle from clogging.
IMPORTANT: If the pressure washer has not been
used for an extended period of time, remove the pres-
sure nozzle from the end of the wand and turn on
water supply. Allow water to run from the end of the
wand until clear.
5. Install the proper pressure nozzle for your cleaning
needs on end of wand. Refer to illustration below.
IMPORTANT: The trigger gun provided with this pres-
sure washer is equipped with a manual trigger lock
to prevent accidental operation of the trigger gun.
The trigger lock should be used whenever the trig-
ger gun is not in use.
To Start:
IMPORTANT: The water must be turned on before
starting. Running the pump dry will cause damage

ger of the trigger gun released for more than 10 min-
utes at any one time or damage to pump may occur.
1. Turn on water supply.
2. Hold wand firmly, release trigger of trigger gun.
3. Place engine ON/OFF switch to ON position.

5. Pull the rope starter slowly until resistance is felt,
then pull briskly. Do not allow the rope starter to snap
back against the engine. Return it gently to prevent
damage to the starter.
