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 unit to a Sears or
other qualifi ed service center for repair
and/or adjustment.
CARBURETOR
Your carburetor has a nonadjustable fi xed
main jet for mixture control. If your engine
does not operate properly due to sus-
pect ed carburetor problems, take your unit
to a Sears or other qualifi ed service center
for repair and/or adjustment.
IMPORTANT:
Never tamper with the
engine governor, which is factory set
for proper engine speed. Over speed ing
the engine above the factory high speed
setting can be dangerous. If you think
the engine-governed high speed needs
adjusting, take your unit to a Sears or
other qualifi ed service center, which has
proper equip ment and experience to make
any nec es sary adjustments.

FUEL SYS TEM
IMPORTANT
: It is important to prevent
gum deposits from forming in essential fuel
system parts such as carburetor, fuel fi lter,
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 car bu re tor are empty.
• Never use engine or carburetor cleaner
prod ucts in the fuel tank or per ma nent
damage may occur.
• Use fresh fuel next season.
NOTE:
Fuel stabilizer is an acceptable
al ter na tive in minimizing the formation of fuel
gum deposits during stor age. Add stabilizer
to gasoline in fuel tank or storage con tain er.
Always follow the mix ratio found on stabilizer
container. Run engine at least 10 min utes
after adding stabilizer to allow the stabilizer
to reach the car bu re tor. Do not drain the gas
tank and carburetor if using fuel stabilizer.
EN GINE OIL
Drain oil (with engine warm) and replace
with clean engine oil. (See “ENGINE” in
the Maintenance section of this man ual).
CYLINDER
1. Remove spark plug.
2. Pour one ounce (29 ml) of oil through
spark plug hole into cylinder.
3. Pull starter handle slowly a few times
to dis trib ute oil.
4. Replace with new spark plug.
OTHER
• Do not store gasoline from one season
to another.
• Replace your gasoline can if your can
starts to rust. Rust and/or dirt in your
gasoline will cause problems.
• If possible, store your unit indoors and
cover it to protect it from dust and dirt.
• Cover your unit with a suitable protective
cover that does not retain moisture. Do
not use plastic. Plastic cannot breathe,
which allows con den sa tion to form and
will cause your unit to rust.
IMPORTANT
: Never cover trimmer while
en gine and exhaust areas are still warm.
CAUTION:
Never store the trimmer
with gaso line in the tank inside a build ing
where fumes may reach an open fl ame
or spark. Allow the engine to cool before
storing in any en clo sure.
