OPERATION
Before Starting
1. Read all manuals provided with this pressure washer.
Become familiar with location and function of all
operating and safety controls.
Grounding Instructions: This product must be electrically
grounded. If it would malfunction or break down,
grounding provides a path of least resistance for electric
current to reduce the risk of electric shock. This machine
must be wired into an appropriate outlet that is properly
installed and grounded in accordance with all local codes
and ordinances.
DANGER: Improper wiring connections of the equip-
ment can result in a risk of electrocution. Check with
a qualified electrician or service personnel if you are
in doubt as to whether the outlet is properly grounded.
WARNING: Make sure all switches and controls are
in the OFF position prior to plugging in electrical cord.
WARNING: 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 prop-
erly 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 due
to possible severe electrical shock and/or damage to
the machine.
2. Connect electrical cord to an overload protected
115VAC/60Hz/1Ph grounded circuit, minimum 18 am-
pere 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 con-
nector, see Figure 1 for location. The water faucet
and supply hose must be capable of providing a mini-
mum of 2.2 gallons per minute (GPM).
4. This machine was factory built for either LP vapor fuel
or Natural Gas. See instructions under Fuel Supply.
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 pressure nozzle on ini-
tial start-up, turn on the water supply, start the pump
by pressing the pump ON switch, and hold the trig-
ger gun trigger open until water appears at the end
of the wand. 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 trigger gun and turn
on water supply, and start the pump by pressing the
pump ON switch. Hold the trigger gun trigger open
and allow water to run from the end of the wand until
clear.
7. Install the adjustable pressure nozzle on end of wand,
refer to Figure 6.
NOTE: To prevent damage to the pressure nozzle, only
place the wrench on hex area when tightening.
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,
refer to Figure 6. 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. See step 8.
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 maintenance has
been performed on the burner assembly, it will be nec-
essary to bleed the air from the gas line before the
pilot will light.
9. If you are running the machine for the first time 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
switches ON and thermostat on highest setting.
Squeeze the trigger of the trigger gun for 15 seconds.
If the burner has not ignited, release the trigger for 5
seconds then squeeze for 15 seconds. If the burner
has not ignited after 10 tries, see the Troubleshoot-
ing Guide in this manual.
CAUTION: Have a qualified gas serviceman install
and service your equipment.
DANGER: Never expose a spark or flame where there
may be unburned gas present.
