Store tool and fuel in an area where fuel vapors
cannot reach sparks or open flames from water
heaters, electric motors or switches, furnaces,
etc.
3. USE THE _'_LLOWINtG :
(16 parts gasoline to I part oil)
WARNING: Alcohol blended fuels, called gasohot
(using ethanol or methanol), can attract moisture
which teads to separation and formation of acids
during storage. Acidic gas can damage the fuel
system of an engine while in storage, To avoid
engine problems, empty the fuel tank before stor-
ing for' :30 days or' longer. Use up fuel teft in the
carburetor by star_:ing the engine and letting it run
until it stops, Use flesh fuel after taldng your unit
out of storage_ Never use engine or' carburetor
cteane_ products in the fuel tank or permanent
engine damage may occm_ See the Storage section
for additional information
_,. FUEL MXXTU_E
Your tool is powered by a two-cycle engine which
requires a fuel mixture of regular unleaded
gasoline and a high quality engine oil specially
made for 2-cycle, air cooled engines. The internal
design of the 2-cycle engine requires lubrication of
moving parts Lubrication is provided when the
recommended mixture of gasoline and oil is used
Gasoline must be clean and fresh.After a short
period of time, gasoline wilt chemically break
down and form compounds that cause hard
starling and damage in 2-cycle engines,
o The correct measure of gasoline to oil is very
important. Too much oi! in the mixture wilt fnul the
spark plug
IcA_ Too little oil or incorrect oil will
cause the engine to overheat and seize.
o Always mix the fuel thoroughly in a container
since gasoline andoil do not readily combine Do not
mix gasoline and oil directly in the fuel tank
4. DO NOT riSE:
o BIA OIL (Boating Institute of America) --
-- Does not have proper additives for aii-cooled
2-cycle engines and can cause engine damage
o AIYrOMO'I IVE OIL --
-- Does not have proper additives for2-cycle engines
and can cause damage
5. HOW TO MLX FUEL AND FNLIL T_K
a Pour 1/2 of the regular unleaded gasoline to be used
into an approved, marked container'. Do not mi_:
gasoline and oil directly in the fuel tank
b Add entire measure of engine oil
c Cover container tightly and shake for one minute
d Slowly remove fuel container cover
e Add remainderofgasoline
fl Cover container tightly and shake again
g Slowly remove fuel container cover
h Slowly remove fuel cap See "Specifications"
for location
i Fill the tank using a spout or funnel
j Reinstall the fuel cap securely

1, Bring the engine to cutting speed beforeentering the
material to be cut°
a Do not run the engine at a higher speed than
necessary. The cuaing line will cut efficiently when
the engine is run at less than flail throttle, At lower
speeds, there is less engine noise and vibration. The
trimmer line will last longer and will be less likely
to "weld" on the spool.
b, If the Trimmer Head does not turn when the
engine is running, make sure the Drive Shaft
Housing is properly seated in the Engine Shloud
Refer' to "Assembly-Drive Shaft Housing."

which can be thrown or become entangled in the
trimmer head

and securely fastened. Refer to "Assembly _
c Hold the tool l'trmly with both hands.

Do not raise the engine above your v,aist.
g Keepali partsofyourbody away from the trim-
mer line and muffler when the engine is runnhag,
h Use only for jobs explained in this manual.
_R _ ADVA__CE
o The line will advance approxhnately 2 inches each
time the bottom of the trimmer head is tapped on the
ground with the engine running at full throttle.
o The most eWmient line length is the maximum length
allowed by the line limiter,
o Airways keep the shield in place when the tool is being
operated.
To ad_ance line:
1 Operate the engine at full throttle
NOTE: Always tap the trimmer head on a grassy area Tapping
on surfaces such as concrete or asphaltcan cause excessive wear
to the trimmer head
d_WA_MD_G
Use only .080" diameter Sears Laser Line ®. Do not
use other materials such as rope, wire string, etc. Wwe
can break during cutting and become a dangerous
missile.
2 Hold trimmer head parallel to and above the grassy
area
14
3
Lightly tap the bottom of the trimmer head on the
ground one time, See Figure 15 Approximately
2 inches of line will be advanced with each tap°
NOTE: If the line is worn down to two inches or
less, more than one tap will be required toobtain the
most efficient line length
NOTE: Scalping can occur when tapping the bot-
tom of the trimmer head on the ground. To avoid
scalping in critical locations, tap the bottom of the
trinamer head in an inconspicuous area when
advancing the trimmer line.

The tip of the line does the cutting. Allow the line to
trim at its own pace, You will achieve better results by
not crowding the line into the cutting area, The right and
wrong way are shown in Figure 16.
The line will easily remove grass and weeds from
around walls, fences, trees and flower beds, but it
also can cut the tender bark of trees or shrubs and scar
fences. To help avoid damage to vegetation or trees with
tender bark, shorten line to 4-5 inches and use less than
full throttle
O
The li_ will wear fas_r and will need tobe advanced
more frequently when you are cutting against rocks,
bricks, concrete, metal fences, etc., than when cut-
ting against trees or wooded fences.
Fortnmming or _calping, use less than full throttle
to increase line life and decrease head wear°
--during light duty cutting
-- next to rocks, bricks, concrete, metal fences, etc
Formowingorsweeping, use full throttle for a good
clean job.
o Avoid letting the trimmer head continuously contact
the ground during normal cutting. Constant contact
will cause trimmer head damage and premature wear
Always wear eye pro_ction. Never lean over the trim-
met head. Rocks or debris can rict_chet or be _ into
eyes and face and cause blindness or o_ber serious injury.

spools or line can iesult in excessive breakage, line
welding and improper line feed,
--Pre-wound spools offer the most convenient
method for replacing line as well as optimum per-

o Always clean dirt and debris from thespool and hub
when performing any type maintenance
o To avoid line welding, keep trimmer line at a max-
