STeP 1: Read operator’s manual
before operating. Before installing
nozzle, turn on water supply and
run machine allowing water to flush
through the system until clear. Pull
wand coupler collar back, insert
desired pressure nozzle into cou-
pler, then secure by pushing collar
forward.
CAUTION: Never replace
nozzles without engaging the safe-
ty latch on the spray gun trigger.
STeP 4: With spray nozzle pointed
away from you or anyone else, press
trigger on spray gun to obtain pres-
surized cold water spray.
STeP 2: Turn on water at faucet
and pull trigger on spray gun al-
lowing water to flow until all air has
discharged from system. Check
for water leaks; tighten as needed.
NOTe: Variable pressure control
wand handle must be turned clock-
wise to enable water to flow out of
the high pressure nozzle.
STeP 3: Read engine manual;
turn engine gas shutoff valve (if
equipped) and choke to run posi-
tion. Turn the engine switch to the
START position and hold it there
until the engine starts.
NOTe: Do not
use the electric starter for more than
five seconds at a time. If the engine
fails to start, release the switch and
wait ten seconds before operating
the starter again. When the engine
starts, allow the engine switch to re-
turn to the ON position. If the engine
is to be started without the battery,
turn switch to start position and pull
rope to start. Turn off choke.

kick back. Do not hold pull rope
tightly in hand.
The four color-coded quick connect nozzles provide a
wide array of spray widths from 0° to 40° and are easily
accessible when placed in the convenient rubber nozzle
holder, which is provided on the front of the machine.
NOTe: For a more gentle rinse, select the white 40°
or green 25° nozzle. To scour the surface, select the
yellow 15° or red 0° nozzle.

STeP 5: For hot water, turn the
burner switch ON when a steady
stream of water flows out of the
spray gun. Burner will light auto-
matically. For steam, open temper-
ature valve counterclockwise. This
lowers the pressure and raises the
temperature.
NOTe: Do not start
machine with burner switch on.
Selection of high or low pressure is accompanied by
turning the handle.
NOTe: High pressure nozzle must
be inserted at end of wand to obtain high pressure. To
apply soap, read washing techniques section.
