SERVICE AND ADJUSTMENTS
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 altitude in
excess of 5000 feet consult with your nearest Sears
Service Center regarding high altitude set changes.
A
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 to a Sears Authorized Service Center
