SERVICE AND ADJUSTMENT
CARBURETOR
Your carburetor has a non-adjustable fixed main jet
for mixture control. It has been completely adjusted at
the factory. If your engine does not operate properly
due to suspected carburetor problems, take your
mower to an authorized Sears Service Center for
repair and adjustment.
ENGINE SPEED
Your engine slow and fast speeds have been factory
set. Do not attempt to increase engine speed or it
may result in personal injury. If you believe that the
engine is running too fast or too slow, take your
mower to an authorized Sears Service Center for
repair and adjustment.
REAR TRAIL SHIELD
The rear trail shield, attached between the rear
wheels of your mower, is provided to minimize the
possibility that objects will be thrown out the rear of
the mower toward the operator.
If the shield becomes damaged, it should be replaced.
