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.
1. Turn on the water supply.
2. Start the engine following the start-up procedures given in the Engine Manual
accompanying this unit.
3. Adjust the engine to a low speed until you see water exiting the water
outlet. (This may take 3-5 minutes.) Adjust the engine throttle back to full
RPM.
4. Once the system is flushed, stop the engine and connect the high pressure
discharge hose to the water outlet of the unit.
5. Connect the trigger gun/dual lance assembly to the high pressure discharge
hose. Connect the desired nozzle to the dual lance assembly.

START-UP/COLD WATER OPERATION:

1. 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 and Auxiliary 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. If use of the auxiliary outlet is desired, plug in auxiliary equipment and move
auxiliary switch to the ON position.
8. 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.
