Setup

Starting the Washer

Never look directly into the nozzle. High pressure
water creates a risk for severe injury.
1. Engage trigger lock and point gun away from
yourself or anyone else. Make sure water supply is
fully turned on.
2. Verify pump is primed. See Priming the Pump,
page 12.
3. Turn the engine switch to the ON position, as well
as the fuel valve (if supplied with) and adjust choke
as needed. Then start engine by pulling recoil rope.
Brace yourself. Hold onto gun/wand firmly with both
hands. Gun will kick back from high pressure created
by pump once engine has started.
4. Disengage trigger lock and trigger gun several
times. Verify high pressure water is sprayed.
5. Make sure to engaged trigger lock whenever
changing nozzles and/or when not in use.
14
Do not allow unit to operate in bypass mode (with trig-
ger closed) for more than three minutes without trig-
gering gun. This can cause premature failure of pump
packing seals and result in costly pump repair.
This pressure washer delivers a high pressure spray
and a variety of spray patterns. There are many
cleaning jobs that can be done without the use of
detergents. If a cleaning agent is required, see
Cleaning with Detergents, page 15, for correct
procedures.
Do not allow spray pattern to remain on a fixed area
for an extended period of time. Possible damage to
that area may occur.

Unloader

Adjustment Knob
The unloader valve on your machine is equipped with an
adjustment knob to adjust the pressure. If less pressure
is needed, turn the adjustment knob counter-clockwise.
To set back to maximum, turn adjustment knob fully
clockwise. Do not over tighten.
Do not overtighten the unloader. Breakage could
result in immediate loss of water pressure and costly
repairs.
