ENGINE
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 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 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.
Immediately prepare your lawn mower for
storage at the end of the season or if the
unit will not be used for 30 days or more.
LAWN MOWER

period of time, clean it thoroughly, remove
all dirt, grease, leaves, etc. Store in a
clean, dry area.
