OPERATING INSTRUCTIONS
Once your unit has been installed by a qualified serviceman and you have
completed the PRE-OPERATION CHECKLIST, you are ready for operation.
The following steps will help you operate your machine safely.
FLUSHING THE SYSTEM:
CAUTION RISK OF UNIT DAMAGE! BE CERTAIN THE GUN & DUAL
LANCE ASSY. ARE NOT CONNECTED TO THE UNIT WHILE
FLUSHING THE SYSTEM.
DEPOSITS TO BE RELEASED FROM THE SYSTEM WHICH
WOULD OBSTRUCT OR DAMAGE THE GUN AND NOZZLE
ASSEMBLY RESULTING IN COSTLY REPAIRS.
1. 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 gun and adjustable pressure dual lance installed.
a. Verify the water supply is on.
b. Move the pump switch to the "ON" position to start the pumping unit.
c. Run the unit for 3-5 minutes.
d. Turn off machine.
e. Once the system is flushed, connect the trigger gun and adjustable
pressure dual lance to the high pressure hose.
COLD WATER OPERATION:
1. Refer to the "Safety Precautions"before starting the unit.
2. Locate the Safety Decals on your unit and heed their warnings.
3. Ensure that the burner switch is in the "OFF" position.
DANGER RISK OF INJECTION CAUSING SEVERE INJURY! KEEP
CLEAR OF NOZZLE!
FRONT OF NOZZLE! DO NOT DIRECT DISCHARGE STREAM AT
PEOPLE OR PETS!
4. Pointing the trigger gun in a safe direction, unlock the trigger gun and
squeeze the trigger. Brace yourself for possible gun kickback when the
pump starts.
5. Move the pump switch to the "ON" position to start the pumping unit.
6. Once the unit has started, perform the following procedures with the gun
open:
a. Inspect for system water and oil leaks.
b. Inspect high pressure hoses for leaks. If a leak is found, DO NOT
TOUCH HOSE AT LEAK!!! TURN UNIT OFF IMMEDIATELY! Replace
hose before using the unit. See "Risk of Injection" warnings. Be sure
that all damaged parts are replaced and that the mechanical problems
are corrected prior to operation of the unit.
7. At this point, the unit is operating as a cold water pressure washer. Trigger
the gun several times and try adjusting the water pressure by rotating the
grip on the dual lance. NEVER place hand or fingers in front of the nozzle
or look directly into the nozzle! High pressure water creates a risk of severe
injury!
8. 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 packing seals, resulting in costly
pump repair.
9. 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 for the correct procedures.
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.
