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 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 thinkthe 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.

"CLEANING" in the Maintenance sec-
tion of this manual).
2. Lubricate as shown in the Maintenance
section of this manual.
3. Be sure that all nuts, bolts, screws, and
pins are securely fastened. Inspect
moving parts for damage, breakage
and wear. Replace if necessary.

surfaces; sand lightly before painting.

FUEL SYSTEM
Storage
position
IMPORTANT: It is important to prevent
gum deposits from forming in essential
fuel system parts such as carburetor, fuel
filter, fuel hose, or tank during storage.
Alcohol blended fuels (called gasohol or
using ethanol or methanol) can attract
moisture which leads to separation and
formation of acids during storage. Acidic
gas can damage the fuel system of an
engine while in storage.
• Empty the fuel tank by starting the en-
gine and letting it run until the fuel lines
and carburetor are empty.
• Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
• Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable
alternative in minimizing the formation of
fuel gum deposits during storage. Add
stabilizer to gasoline in fuel tank or stor-
age container. Always follow the mix ratio
found on stabilizer container. Run engine
at least 10 minutes after adding stabilizer
to allow the stabilizer to reach the car-
buretor. Do not empty the gas tank and
carburetor if using fuel stabilizer.
ENGINE OIL
Drain oil (with engine warm) and replace
with clean engine oil. (See "ENGINE" in
the Maintenance section of this manual).
