BEFORE STARTING ENGINE
WARNING: Be sure to read the fuel
information in the safety rules before
you begin. If you do not understand
the safety rules, do not attempt to fuel
your unit. Call the 1-800 number listed
on the front ofthis manual.
FUELING ENGINE
This engine is certified to0perate on
unleaded gasoline. Before operation,
gasoline must be mixed with a good
quality 2-cycle air-cooled engine oil.
We recommend Craftsman brand oil.
Mix gasoline and oil at a ratio of 40:1
(A 40:I ratio is obtained by mixing 3.2
ounces of oil with 1 gallon of unleaded
gasoline). DO NOT USE automotive oil
or boat oi!.These oilswill cause
engine damage. When mixing fuel,
follow instructions printed on container.
Once oil is added to gasoline, shake
Container momentarily to assure that
the fuel is thoroughly mixed. Always
read and follow the safety rules
relating to fuel before fueling your unit.
IMPORTANT
Experience indicates that alcohol
blended fuels (called gasohol or using
ethanol or methanol) can attract mois-
ture which leads to separation and
formation ofacids during storage.
Acidic gas can damage the fuel sys-
tem of an engine while in storage.
Toavoid engine problems, empty fuel
system before storage for 30 days or
longer. Drain gas tank, start engine and
let it run until fuel lines and carburetor
are empty. Use fresh fuel next season.
Never use engine or carburetor clean-
er products in the fuel tank or perma-
nent damage may occur.

less likely to "weld" onto the spool.
Always release the throttle trigger and
allow the engine to return to idle speed
when not cutting.
To stop engine:
• Release the throttle trigger.

• For trimming or scalping, use less
than full throttle to increase line life ;
and decrease head wear, especially:
• During light duty cutting.
• Near 0bjectsaround which the line
can wrap such as small posts,
trees or fence wire.
• For mowingor sweeping,use full

WARNING::AIways wear eye protec-
tion. Never lean over the trimmer head.
Rocks or debris can ricochet or be
thrown into eyes and face and cause
blindness or other serious injury.
TRIMMING - Hold the bottom of the
trimmer head about 3 in. (8 cm) above
the ground and at an angle. Allow only
the tip of the line to make contact. Do
not force trimmer line into work area.

SCALPING - The scalping technique
removes unwanted vegetation. Hold
the bottom of the trimmer head about 3
in. (8 cm) above the ground and at an
angle. Allow the tip of the line to strike
the ground around trees, posts, monu-
ments, etc. This technique increases
line wear.
MOWING - Your trimmer is ideal for
mowing in places conventional lawn
mowers cannot reach. In the mowing
position, keep the line parallel to the
ground. Avoid pressing the head into
the ground as this can scalp the
ground and damage the too!.
