Operation Instructions

Before Starting
1. Read all manuals provided with this pressure
washer. Become familiar with location and function
of all operating and safety controls.
WARNING: Make sure all switches and controls are
in the OFF position prior to plugging in electrical
cord.
DANGER: Do not stand in water while plugging or
unplugging electrical cord.
CAUTION: This pressure washer is equipped with a
UL approved ground fault circuit interrupter (GFCI)
power cord. Use UL grounded type receptacles of
proper voltage and amperage ratings. Where a
properly grounded receptacle is not available, it is
the personal responsibility of the owner to have
one installed. Always disconnect power before
servicing your pressure washer.
CAUTION: This machine is equipped with a 35 foot
long power cord protected by a ground fault circuit
interrupter (GFCI). DO NOT use extension cords
because of possible severe electrical shock and/or
damage to the machine.
DANGER: This equipment is designed to run on
vapor fuel. DO NOT use liquid fuel. Have a
qualified serviceman install and service your
equipment.
2. Connect electrical cord to an overload protected
230VAC/60Hz/1PH grounded circuit, minimum 15
ampere rated. Test the GFCI using the reset and
test procedure located on the GFCI device. Do not
use machine if GFCI fails test. The GFCI must be
reset and tested with every use.
WARNING: Check hoses, fittings, wand, trigger gun
and fuel connections daily for signs of wear, cracks
and looseness, and replace as required.
3. Connect water supply hose to the garden hose
connector located on machine's front. The water
faucet and supply hose must be capable of
providing a minimum of 3.0 gallons per minute
(GPM).
4. Connect proper gas supply. See instructions under
Using LP Vapor Fuel and Converting to Natural
Gas.
5. Check pump oil level.
6. If detergents are to be used, only use detergents
intended for pressure washers. Follow instructions
on the detergent container.

IMPORTANT: Before installing nozzle on initial
start-up, turn on the water supply and pump switch
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
nozzle from the end of the wand and turn on water
supply and pump switch. Allow water to run from
the end of the wand until clear.
7. Install the pressure nozzle on end of wand.
NOTE: To prevent damage to the pressure nozzle,
only place the wrench on hex area when tightening.
IMPORTANT: The trigger gun provided with this
pressure washer is equipped with a manual trigger
lock to prevent accidental operation of the trigger
gun. The trigger lock should be used whenever the
trigger gun is not in use.
IMPORTANT: Pump may require priming the first
time the pressure washer is run.
8. If you are running the machine for the first time, or
the machine has been sitting for a period of time,
the pump may require priming. To prime the pump,
run pressure washer with only the pump switch on.
IMPORTANT: On initial start up or if a new gas
bottle is installed it is necessary to bleed the air
from the gas line before the pilot will light.
9. If you are running the machine for the first time,
have changed the gas bottle, or have performed
maintenance to the burner assembly, there will be
air in the gas line. To bleed out the air from the gas
line, run pressure washer with pump and burner
switch on and thermostat on highest setting.
Squeeze trigger gun for 15 seconds. If the burner
has not ignited, release trigger for 5 seconds and
re-squeeze. If the burner has not ignited after 10
tries, see the Troubleshooting Guide in this
manual.
