a Use only recommended fuel mixtures.

b MLxand pour fue! outdoors and where there are

no sparks or flames.

c Use a container approved for fuel,
d, Do not smoke or allow smoking near fuel or the

tool or while using the tool,

e Wipeupallfuelspillsbeforestartingengine,
f Moveatleas_ 10feetawayfromfuelingsitebefore

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 and oil 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."

J. CUTTING

Inspect the area to be cut before each use. Remove

objects (rocks. broken glass, nails, wire. string, etc )

which can be thrown or become entangled in the
trimmer head

b Al_ays keep the engine on the right side of your

bod_,.

a Inspect the entire tool before each user Replace

damaged parts Check for fuel leaks and make sure
all fasteners are in place and securely fastened

b Use only .080" diameter Sears Laser Line ®.

d Make sure the trimmer head is properly installed

and securely fastened. Refer to "Assembly _

c Hold the tool l'trmly with both hands.
d Keep firm footing and balance. Do not over-reach
e Keep the trimmer head below waist level.

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 to be 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 inexcessive breakage, line
welding and improper line feed,

--Pre-wound spools offer the most convenient

method for replacing line as well as optimum per-

NOTE: It is important to prevent gum deposits flora

forming in essential fuel system parts such as the car-
buretor; fuel filter, fuel hose, or tank during storage.

Alcohol blended fuels, called Gasohol (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.
