OPERATING INSTRUCTIONS

Start-up/Cold Water Operation

Refer to the "Safety Precautions" pgs. 3-5 before start-
ing the unit.
Locate the Safety Decals on your unit and heed their
warnings.
Never place hand or fingers in front of nozzle or look
directly into the nozzle. High pressure water creates a
risk of severe injury.
1. Ensure the burner switch is in the "OFF" position.
2. 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.
3. Once the engine has started, ensure the engine throttle
is adjusted to full RPM and perform the following
procedures with the trigger gun open:
Inspect for system water leaks, oil leaks and fuel leaks.
If a fuel leak is found, TURN UNIT OFF IMMEDIATELY!
See "Fire & Ventilation Precautions", 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.
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 "Spray Precautions", pg.
3-4. 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.
4. At this point, the unit is operating as a cold water
pressure washer. Trigger the gun several times and
try adjusting the water pressure.
Note: Be certain to lock the trigger gun in the "OFF"
position whenever changing the quick connect nozzles.
5. 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 13-14 for the correct
procedures.
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.
Do not allow spray pattern to remain on a fixed area
for an extended period of time. Possible damage
may occur to the area.
