FLUSHING THE SYSTEM:
This unit has a steel coil which, after sitting, 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 per-
formed WITHOUT the high pressure hose, gun and lance assembly installed.
1. 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.
WARNING: CAUTION RISK OF UNIT DAMAGE. BE CERTAIN THE HOSE, GUN AND NOZZLE ASSEMBLY
ARE NOT CONNECTED TO THE UNIT WHILE FLUSHING THE SYSTEM.
MINERAL DEPOSITS TO BE RELEASED FROM THE SYSTEM WHICH WOULD OBSTRUCT OR
DAMAGE THE GUN AND NOZZLE ASSEMBLY RESULTING IN COSTLY REPAIRS.
START-UP/COLD WATER OPERATION:
1. Refer to the Safety Warnings 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.
WARNING: CAUTION RISK OF DAMAGE. DO NOT ALLOW SPRAY PATTERN TO REMAIN ON A FIXED
AREA FOR AN EXTENDED PERIOD OF TIME. POSSIBLE DAMAGE MAY OCCUR TO THE AREA.
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!
ADJUSTABLE GRIP
DANGER RISK OF INJECTION CAUSING SEVERE INJURY! KEEP CLEAR OF NOZZLE! NEVER PLACE
HAND OR FINGERS IN FRONT OF NOZZLE! DO NOT DIRECT DISCHARGE STREAM AT PEOPLE OR
PETS!
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.
