OPERATING INSTRUCTIONS
PRIMING THE PUMP:
It is essential to prime the pump and ush the unit each time the water supply
has been disconnected from the unit OR whenever the unit has set for any
period of time. 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 contaminated water must be ushed from the system before start-up. This
procedure should be performed without the high pressure hose, gun and dual
lance assembly installed.
DIRECT FEED: All units.
1. Turn on the water supply.
2. Low pressure water will begin owing from the water outlet. This allows the
unit to prime and purge any air from the system. The unit is primed when
water ow is uninterrupted by air.
3. Once the unit is primed, turn off the water supply and connect the high
pressure discharge hose to the water outlet of the unit. (Note: The trigger
gun and dual lance assembly should already be connected to the high
pressure discharge hose at this time.)
4. Turn on the water supply.
SUCTION FEED: These models have the ability to draw water from a static source
and can provide a suction lift of 5' with a 3/4" inlet hose. We recommend
the following for suction feed.
1. Immerse a 3/4" x 5' long inlet hose into 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.
NOTE: This may take up to 3-5 minutes. Adjust the engine throttle back to
full RPM.
4. Once the unit is primed, stop the engine and connect the high pressure
discharge hose to the water outlet of the unit.
NOTE: The trigger gun and dual lance assembly should already be connected
to the high pressure discharge hose at this time.
START-UP/COLD WATER OPERATION:
1. Refer to the "Safety Precautions" pgs. 4-7 before starting the unit.
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 manufacture's instructions in the engine manual accompanying this
unit.
5. Once the engine has started, ensure the engine throttle is adjusted to full
RPM and perform the following procedures with the trigger gun open:
a. Inspect for system water leaks, oil leaks and fuel leaks. If a fuel
leak is found, TURN UNIT OFF IMMEDIATELY! See "Risk of Fire",
pg. 4. Be sure that all damaged parts are replaced and that the
mechanical problems are corrected prior to operation of the unit. If you
require service, contact Customer Service.
b. Inspect high pressure hoses for kinking, cuts and leaks. If a cut or
leak is found, DO NOT TOUCH HOSE AT LEAK!!! TURN UNIT OFF
IMMEDIATELY! Replace hose before starting the unit. See "Risk of
Injection", pg. 5. Be sure that all damaged parts are replaced and that
the mechanical problems are corrected prior to operation of the unit. If
you require service, contact Customer Service.
6. At this point, the unit is operating as a cold water pressure washer. Trigger
the gun several times and try adjusting the water pressure. NEVER place
hand or ngers in front of the nozzle or look directly into the nozzle! High
pressure water creates a risk of severe injury!
7. Do not allow unit to operate in bypass mode (with trigger closed) for more
than three minutes without triggering the gun. Failure to follow this simple
rule can cause premature failure of pump packings, resulting in costly pump
repair.
8. Your pressure washer can deliver high pressure spray and a variety of spray
patterns using cold water. If you wish to use the Hot Water application or
Cleaning with Detergents, see page 17 for the correct procedures.
CAUTION
RISK OF UNIT DAMAGE.
BE CERTAIN THE HOSE, GUN
& DUAL LANCE ASSY. ARE
NOT CONNECTED TO THE
UNIT WHILE PRIMING THE
PUMP. PRIMING ALLOWS
MINERAL DEPOSITS TO BE
RELEASED FROM THE SYSTEM
WHICH WOULD OBSTRUCT
OR DAMAGE THE GUN AND
NOZZLE ASSEMBLY RESULTING
IN COSTLY REPAIRS.
