Operations
Operating Instructions
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
coupler, then secure by pushing
collar forward. CAUTION: Never
replace nozzles without
engaging the safety 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
pressurized cold water spray.
STEP 2: Turn on water at faucet
and pull trigger on spray gun
allowing 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 clockwise to enable water to
flow out of the high pressure
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
temperature valve counterclock-
wise. This lowers the pressure and
raises the temperature. NOTE: Do
not start machine with burner
switch on.
STEP 3: Read engine manual; turn
engine gas shutoff valve (if
equipped) and choke to run
position. 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 return 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.
CAUTION: Small engines may
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 acces-
sible 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.
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.
