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 engine is running too fast or
too slow, take your mower to a Sears or
other qualified service center for repair
and adjustment.
CARBURETOR
Your carburetor
is not adjustable.
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 adjustment.
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.
If you think
the 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.
