CARBURETOR •
The carburetor of your high pressure washer is pre-set at
the factory. The carburetor should not be tampered with. If
your pressure washer is used at an altititude in excess of
5000 feet consult with your nearest Sears Service Center
regarding high altitude set changes.
ENGINE SPEED
CAUTION: Engine speed was properly
adjusted at the factory and should require
no additional adjustment, Do NOT attempt
to change engine speed. If you believe the
engine is running too fast or too slow, take
your pressure washer to a Sears Authorized
Service Center for repair and adjustment,
Changing engine governed speed will void
engine warranty.
Your pressure washer runs at a constant speed. This con-
stant operating speed is maintained by a mechanical, fly-
weight type, fixed speed governor. DO NOT tryto adjust
the governed speed setting for the following reasons:
• High engine speeds are dangerous and increase the
risk of persona! injury or damage to equipment.
° Low engine speeds impose a heavy toad on the
engine when sufficient.engine power is not available
and may shorten engine life.
NOZZLE MAINTENANCE
If the nozzle becomes restricted or clogged with foreign
materials, such as dirt, excessive pump pressure may
develop. A partially clogged nozzle can cause a pulsing
sensation during use. This generally is not a pump related
problem, but rather a clogged or partially restricted nozzle.
If the nozzle becomes clogged or partially restricted,
immediately clean the nozzle with the kit included with
your pressure'washer by following these instructions:
° Shut off the engine and turn off the water supply.
* Separate the wand from the gun.
• Open to stream spray.
Remove nozzle from the end of the wand using a 2mm
or 5/64 allen wrench (like the one included in the kit).
Use the wire included in the kit or small paper clip to
free foreign materials clogging or restricting the nozzle.
Move the wire back and forth to clear obstruction.
Remove additional debris by back flushing Water sup-
ply through wand. Back flush between 30 to 60 sec-
onds. Turn wand to stream spray and move nozzle
from tow to high pressure while flushing.
• Reinstall nozzle into wand. DO NOT overtighten.
° Reconnect wand extension to spray gun.
° Reconnect the water supply, turn ONthe water, and
start the engine.
• Test the pressure washer by operating with nozzle in
the high and the tow pressure positions.
