OPERATING INSTRUCTIONS
FLUSHING THE SYSTEM:
This unit has a steel coil which, after setting, will cause the water remaining in
the coil from the previous usage to turn brown or black. This water must be
flushed from the system before start-up. This procedure should be performed
WITHOUT the high pressure hose, gun and lance assembly installed.
. Turn on the water supply.
2. Start engine on unit. Low pressure water will begin flowing from the water
outlet. This allows the unit to flush any particles from the system. The unit
is flushed when the water is clear.
3. Once the system is flushed, turn off engine and connect the high pressure
hose to the water outlet of the unit.
4. Connect the trigger gun and dual lance assembly to the high
pressure hose.
5. Install desired nozzle into dual lance assembly.
START-UP/COLD WATER OPERATION:
. Refer to the Safety Warnings on pages 4-8 before starting the machine.
2. Locate the Safety Decals on your unit and heed their warnings.
3. Ensure the Burner Switch is in the
OFF
position.
4. Pointing the trigger gun in a safe direction, unlock the trigger gun and squeeze
the trigger. Hold the trigger gun open while starting the engine according
to the manufacturer’s instructions in the engine manual accompanying
the machine. Brace yourself for possible gun kickback when the engine
starts.
5. Once the engine has started, perform the following procedures with the gun
open:
a. Inspect for system water leaks, oil leaks, and fuel leaks. If
a fuel leak is found, TURN MACHINE OFF IMMEDIATELY!
See “Risk of Explosion or Fire” warnings. Be sure that all
damaged parts are replaced and that all mechanical
problems have been corrected prior to operation of the
unit. Contact Customer Service if necessary.
b. Inspect high pressure hoses for kinks, cuts, and leaks. If a
cut or leak is found, TURN MACHINE OFF IMMEDIATELY!
Replace hose before starting the machine. See “Risk of
Injection” warnings. Be sure that all damaged parts are
replaced and that all mechanical problems have been
corrected prior to operation of the unit. Contact Customer
Service if necessary.
6. The unit is now operating as a cold water pressure washer. Trigger the gun
several times. Rotate adjustable grip on the dual lance for high and low
pressure application. NEVER place hand or fingers in front of the nozzle
or look directly into the nozzle!
7. Do not allow the machine to operate in the bypass mode (with the trigger gun
closed) for more than three minutes without triggering the gun. Failure to
follow this simple rule can cause premature failure of the pump packings.
HOT WATER OPERATION:
. Follow preceding steps -7 for “Start-up / Cold water operation”.
2. Move the Burner switch to the
ON
position.
3. Recheck the system for fuel leaks. If a fuel leak is found, TURN MACHINE
OFF IMMEDIATELY! See “Risk of Explosion or Fire” warnings. Be sure
that all damaged parts are replaced and that all mechanical problems have
been corrected prior to operation of the unit. Contact Customer Service if
necessary.
Note: Upon initial start-up, water will begin turning hot in approximately 20
seconds and will reach maximum temperature within 2-1/2 minutes providing
that the trigger gun remains open. The burner will not fire when the trigger
is released.

TIME. POSSIBLE DAMAGE MAY
OCCUR TO THE AREA.
CAUTION
RISK OF UNIT DAMAGE.
BE CERTAIN THE HOSE, GUN
AND NOZZLE ASSEMBLY ARE
NOT CONNECTED TO THE
UNIT WHILE FLUSHING THE

MINERAL DEPOSITS TO BE
RELEASED FROM THE SYSTEM
WHICH WOULD OBSTRUCT
OR DAMAGE THE GUN AND
NOZZLE ASSEMBLY RESULTING
IN COSTLY REPAIRS.
