ENGINE SPEED
Your engine speed has 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 lawn mower to a
Sears or other qualified service center for
repair and adjustment.
CARBURETOR
Your carburetor has a non-adjustable
fixed main jet for mixture control. If your
engine does not operate properly due to
suspected carburetor problems, take your
lawn mower to a Sears or. other qualified
service
center for repair and/or adjust-
ment.
IMPORTANT:
Never tamper with the
engine governor, which is factory set for
proper engine speed.
Overspeeding
the
engine above the factory high speed
setting can be dangerous.

engine-governed
high speed needs
adjusting, contact
a Sears or other
qualified service
center, which has
proper equipment and experience
to
make any necessary adjustments.
