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 1-800-235-5878.
FUELING ENGINE
This engine is certified to operate 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 40:1 ratio is obtained by mixing 3.2
ounces of oil with 1 gallon of unleaded
gasoline). DO NOT USE automotive oil
or boat oil. These oils will cause
engine damage. When mixing fuel,
follow instructions printed on container.
allowing it to return to its original form.
CHOKE
The choke helps to supply fuel to the
carburetor during starting. This allows
you to start a cold engine. Activate the
choke by moving choke lever to the Full
position. After the engine has started,
move the choke to the Off position.
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 of acids during storage.
Acidic gas can damage the fuel sys-
tem of an engine while in storage.
To avoid engine problems, empty the
fuel system before storage for 30 days
or longer. Drain the gas tank, start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh
fuel next season.

OPERATING INSTRUCTIONS
OPERATING POSITION
To advance line, tap bottom of trimmer
head on ground one time.
ALWAYS WEAR: _ _. _
j_ Eye Protection
H_°;gY _t_s __
Cut from your right to your left.
Bring the engine to cutting speed be-
fore entering the material to be cut.
Do not run the engine at a higher
speed than necessary. The cutting line
will cut efficiently when the engine is
run at less than full throttle. At lower
speeds, there is less engine noise and
vibration. The cutting line will last
longer and will be less likely to "weld"
onto the spool.
If the trimmer head does not turn when
the engine is in operation, make sure
the drive shaft housing is properly
seated in engine shroud.
Always release the throttle trigger and
allow the engine to return to idle speed
when not cutting.
To stop engine:
• Release the throttle trigger.
• Push and hold down the on/stop
switch until the engine has stopped
completely.
TRIMMER LINE ADVANCE
The trimmer line will advance approxi-
mately 2 in. (5 cm) each time the bot-
tom of the trimmer head is tapped on
the ground with the engine running at
full throttle.
The most efficient line length is the
maximum length allowed by the line
limiter.
Always keep the shield in place when
the tool is being operated.
To Advance Line:
• Operate the engine at full throttle.
• Hold the trimmer head parallel to and
above the grassy area.
• Tap the bottom of the trimmer head
lightly on the ground one time. Ap-
proximately 2 in. (5 cm) of line will be
advanced with each tap.
Llrnplei_e rg_hU.ts line t° "_
Always tap the trimmer head on a
grassy area. Tapping on surfaces such
as concrete or asphalt can cause ex-
cessive wear to the trimmer head.
Ifthe line is worn down to 2 in. (5 cm)
or less, more than one tap will be re-
quired to obtain the most efficient line
length.
WARNING;Use only .080" (2 mm)
diameter line. Other sizes of line will
not advance properly and can cause
serious injury. Do not use other materi-
als such as wire, string, rope, etc. Wire
can break off during cutting and be-
come a dangerous missile that can
cause serious injury.
CUTTING METHODS
WARNING:Use minimum speed and
do not crowd the line when cutting
around hard objects (rock, gravel,
fence posts, etc.), which can damage
the trimmer head, become entangled
in the line, or be thrown causing a seri-
ous hazard.
• The tip of the line does the cutting.
You will achieve the best perform-
ance and minimum line wear by not
crowding the line into the cutting
area. The right and wrong ways are
shown below.
Tip of the Line Line Crowded Into
Does The Cutting Work Area
Right_' Wrong " _'=.
• 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 dam-
age especially to delicate vegetation
or trees with tender bark, shorten line
to 4-5 in. (10-13 cm) and use at less
than full throttle.

CARBURETOR ADJUSTMENT
WARNING:The trimmer head will be
spinning during most of this procedure.
Wear your protective equipment and
observe all safety precautions. After
making mixture adjustments, recheck
idle speed.
Carburetor adjustment is critical and if
done improperly can permanently
damage the engine as well as the car-
buretor. If you require further assis-
tance or are unsure about performing
this procedure, call our customer as-
sistance help line at 1-800-235-5878.
Old fuel, a dirty air filter, a dirty fuel fil-
ter, or flooding may give the impres-
sion of an improperly adjusted carbu-
retor. Check these conditions before
adjusting the carburetor.
The carburetor has been carefully set
at the factory. Adjustments may be
necessary if you notice any of the fol-
lowing conditions:
• Engine will not idle. See "Idle Speed"
under adjusting procedure.
• Engine dies or hesitates instead of
accelerating. See "Acceleration
Check" under adjusting procedure.
• Loss of cutting power. See "Mixture
Adjustment" under adjusting
procedure.
There are two adjustment screws on
the carburetor.

• Turn clockwise to increase engine
speed if engine stalls or dies.
• Turn counterclockwise to decrease
speed.
No further adjustments are necessary
if performance is satisfactory.
Mixture Adjustment "H"
DO NOT operate engine at full throttle
for prolonged periods while making ad-
justments. Damage to the engine can
occur. Extend line to the length allow
by the line limiter and cut some grass.
Based on performance while cutting,
turn the mixture adjustment in
1/16-turn increments as follows:
• Clockwise until the engine has good
power while cutting with no hesita-
tion.
Do not adjust by sound or speed, but
judge by how well the engine per-
forms while cutting.
• Counterclockwise if the engine has
speed but dies or lacks power while
cutting.
After completing adjustments, check
for acceleration. Reset if necessary.
Acceleration Check
If engine dies or hesitates instead of
accelerating, turn mixture adjustment
counterclockwise until you have
smooth acceleration. Recheck and ad-
just as necessary for acceptable per-
formance.
