GASOLINE
The two-cycle engine on this product requires a fuel mix-
ture of regular unleaded gasoline and a high quality en-
gine off for lubrication of the bearings and other moving
parts. The correct fue!!oil mixtureis 40:1 (see FuelMix-
furs Chart). Too little oil or the incon'ect oil type _ll
cause poor performance and may cause the engine to over-
heat and seize.
Gasoline and oil must be premixed in a clean approved fuel
container. Always use fresh regular unleaded gasoline.
IMPORTANt. Experience indicates that alcohol
blended fuels called gasohol (or using ethanol or metha-
nol) can attract moisture, which leads to oil]gas separa-
tion and formation of acids during storage. Acidic gas can
damage the fuel system of an engine while in storage. To
avoid engine problems, the fuel system should be emptied
before storage for 30 days or longer° Drain the gas tank,
then run the fuel out of the carburetor and fuel lines by
starting the engine and letting it run until it stops. Use
fresh fuel next season. See STORAGE instructions for
additional information. Never use engine or carburetor
cleaner products in the fuel tank or permanent damage
may occur.
FUEL STABILIZER
Fuel stabilizer is an acceptable alternative in minimizing
the formation of fuel gum deposits during storage. Add
stabRizer to gasoline in fuel tank or storage container.
Always follow the fuel mix ratio found on the stabilizer
container. Run engine at least 10 minutes after adding
stabilizer to allow the stabilizer to reach the carburetor.
You do not have to drain the fuel tank for storage ifyan are
using fuel stabilizer.
CRAFTSMAN 40:1 2cycle engine oil is speciany blended
with fuel stabi_ers. If you do not use this Sears off, you
can add a fuel stabilizer (such as Craftsman No. 33500) to
your fuel tank.
CRAFTSMAN 40:1 2 cycle off is strongly recommended.
This oil is specially blended with fuel stabilizers for
increased fuel stability (extends fuel life up to 5 times
longer) and reduced smoke.
If CRAFTSMAN 2 cycle oil is not available, use a good
quality 2 cycle AIR-COOLED engine oil that has a
recommended fuel mix ratio of 40:l.
IMPORTANTI Do not use:
• AUTOMOTIVE OIL
•BOAT OILS (NMMA, BIA. etc.)
These oils do not have proper additives for 2-cycle,
AIR-COOLED engines and can cause engine damage.
GASOLINE AND OIL MIXTURE
Mix gasoline and oil as follows:
° Consult chart for correct quantities.
• Do not mix gasoline and oil directly in the fuel tank.
FOR ONE GALLON:
• Pour 3.2 ounces of high quality, 2-cycle engine oil
into an empty, approved one gallon gasoline con-
tainer.
• Add one gallon of regular unleaded gasoline to the
gallon container, then securely replace the cap_
Shake the container momentarily.
• The mixture is now ready for use. Fuel stabilizer
can be added at this time if desired; follow mixing
instructions on the label,

hanging straps, ties, tassels, etc; they can be
caught in moving parts. Secure hair so it is
above shoulder length, Being fully covered will
help protect you from pieces of toxic plants
such as poison ivy thrown by the blade, which
could be more of a hazard than touching the
plant itself.
c. Keep hair, fingers, and all other parts of the
body away from openings and moving parts,
d Do not operate this tool when you are
tired, ill, or under the influence of alcohol,
drugs, or medication
e. Do not swing the tool with such force that
you are in danger of losing your balance.
f, Never start or run the engine inside a
closed room or building. Breathing exhaust
fumes can kill.
g, Keep handles free of oil and fuel.
2. TOOL
a. Inspect the entire tool before each use.
Replace damaged parts Check for fue! leaks
and make sure all fasteners are in place and se-
curely fastened.
b, Use only SEARS .080" diameter line.
Never use wire, rope, string, etc,
c, Be sure the shield is properly attached.
d. Make sure the trimmer head is properly
installed and securely fastened. Refer to
"Assembly"
e Make carburetor adjustments with the
drive shaft housing supported to prevent the
trimmer line from contacting any ol_ject.
f Keep others away when making carbure-
tor adjustments.
g Use only genuine Sears accessories or attach-
ments as recommended
3. CUTTING
a. Inspect the area to be cut before each
use. Remove ol_jects (rocks, broken glass,
nails, wire, string, etc.) which can be thrown or
become entangled in the trimmer head
b. Always keep the engine on the right-
hand side of your body.
c, Hold the tool firmly with both hands.
-11 -

dKeep firm footing and balance. Do not
over-reach.
eKeep the trimmer head below waist level.
f_ Do not raise the engine above your waist.
g. Keep all parts of your bodyaway from the
trimmer line when the engine is running.
h Keep all parts of your body away from a
hot muffler.
i. Use only for jobs explained in this man-
ual.
• A WARN_G
Avmd any bodily contact with the muffler when
starting a warm engine. A hot muffler can cause
serious burns.
B. TRIMMER LINE ADVANCE
•The trimmer line will advance approxi-
mately 2 inches (5 cm) each time the bottom
of the trimmer head is tapped on the ground
with the engine running at full throttle.
• The most efficient line length is the maxL
mum length allowed by the line limiter.
oAlways keep the shield in place when the
tool is being operated• Figure 5.
•To Advance Line:
LOperate the engine at full throttle_
2 Hold the trimmer head parallel to and above a
grassy area.
3. Tap bottom of trimmer head lightly on ground
one time. See Figure 5 • Approximately 2" (5
cm) of line will be advanced with each tap.
NOTE: Always tap trimmer head on a grassy
area. Tapping on surfaces such as concrete or
asphalt can cause excessive wear to the trim-
mer hea4

Figure 5
If the line is worn down to 2 inches (5
cm) or less, more than one tap will be re-
quired to obtain the most efficient line length.
AWARN G
Use only Sears .080" diameter line. Other sizes
of line will not advance properly and can cause
serious injury. Do not use other materials such
as wire, string, rope, etc. Wire can break off dur-
ing cutting and become a dangerous mlssde that
can cause serious injury.
C. CUTTING METHODS
AWARNING ]
Use minimum speed and do not crowd the linel
when cutting around hard objects (rock, _ravel, I
fence posts, etc), which can damage the tmmmer I
head, become entangled in the hne, or be[
thrown causing a serious hazard. ]
• The tip of the line does the cutting. You will
achieve best performance and minimum line wear
by not crowdingthe line into the cutting area. The
right and wrong ways are shown in Figure 6.
•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 especially to delicate vegetation or trees
with tender bark, shorten line to 4-5 inches (10 -
12.5 cm) and use at less than full throttle.
•For trimming or scalping, use less than full
throttle to increase line life and decrease
head wear, especially:
- during light duty cutting.
- near objects around which the line can wrap
such as small posts, trees or fence wire.
•Formowingorsweeping, usefullthrottlefor
a good clean job.
WARNING I
Always wear eye protection. Never lean over the J
trimmer head. Rocks or debris can ricochet or
be thrown rote eyes .and face and cause bhnd-]
ness or other sermus injury. J
1. TRIMMING - Figure 7. Hold the bottom of
the trimmer head about 3inches (7.5 cm) above
the ground and at an angle. Allow only the tip of
the line to make contact, Do not force the trimmer

3. ADJUSTING PROCEDURE
a. PREPARATION
ePoor engine performance can be a result of
other causes such as dirty air filter, carbon
build-up on muffler outlets, etc. See
"Trouble Shooting Chart" before proceed-
ing with carburetor adjustments.
•For best results, it is recommended that you
have your SEARS Service Center/Depart-
ment make all carburetor adjustments. Your
dealer has the training, experience, and tools nec-
essary to properly adjust your unit to meet our
factory performance specifications. This service
is not covered by warranty. If it becomes necessary
for you to make carburetor adjustments yourself,
follow the described procedures very carefully.
•Very small adjustments can affect engine
performance. It is important to turn the screw a
very small amount per adjustment and test per-
formance before making further adjustments.
Each adjustment should be no more than the
width of the slot in the adjusting screw.
•This is a complicated task and it is impor-
tant to follow instructions in sequence as
indicated•
1. Use a fresh fuel mix. See "Fueling Your En-
gh_e? '
2. Make sure the line extends to the length al-
lowed by the line limiter to provide correct
load on engine.
3. Start the engine. Cut grass fbr 3 minutes to
warm engine. The engine must be at operat-
ing temperature before carburetor adjust-
ments can be peT)Cormed co_Tectly.
b. IDLE SPEED ADJUSTMENT
1. Allow engine to idle.
2. Adjust idle speed screw (Figure 21 ) until
engine continues to run without stalling.
-Turn screw clockwise to increase engine
speed if the engine stalls or dies.
-Turn screw counterclockwise to slow en-
gine down.
3. Follow instructions in '_cceleration
Check" and "Deceleration Check"
4. No further adjustments are necessary if
performance is satisfactory.
1. TROUBLE SHOOTING SUGGESTIONS
-Engine will not continue to run at idle posi-
tion. See "Idle Speed Adjustment" and "Mix°
ture Adjustment,'
- Engine dies or hesitates when it should accel-
erate. See '_cceleration Check."
- Loss of cutting power which cannot be cor-
iected by cleaning the air filter. See 'Mixture
Adjustment."
- Engine does not return to idle from full throt-
tle within 2 seconds_ See "Deceleration
Check."
- Engine will not run. See "Trouble Shooting
Chart?' Then if carburetor requires adjust-
ment, begin with "Basic Carburetor Settings'
p_roec A WARNING ....
trimmer head will be spinning during this
edure. Wear your protective equipment and
[observe all safety instructions.
c. ACCELERATION CHECK
1. Allow engine to idle.
2. Squeeze trigger fully.
a. If performance is satisfactor_ pro-
ceed to "d. Deceleration Check."
b. If the engine does not accelerate
smoothly, turn the mixture screw (Fig-
ure 21 ) counterclockwise a small
amount (no more than the width of the
slot in the adjusting screw).
3. Repeat step "2." until smooth acceleration
is obtained. Do not attempt to adjust the
screw beyond the stops as damage can occur.

GAS TRIMMER/BRUSHCUTTER STORAGE
INSTRUCTIONS
If your trimmer/brushcutter is to be stored for a period of
time, clean it thoroughly prior to storage. Remove any dirt,
sawdust, leaves, oil, grease, etc. Store in a clean dry area.
Clean the entire unit.
Clean air filter. Refer to "Customer Responsibilities",
Open the line head assembly and clean any dirt, grass
or debris that has collected. Inspect the cutting line, if
old (chalky look and sticky to the touch), remove and
discard Install fresh new line the next time product is to
be used.
• Lightly oi! external metal surfaces to prevent rust from
forming.
CAUTION: Wear protective gloves when
handling blade. The blade is sharp and
can cut you even when it is not moving. _
If your unit is equipped with a blade, remove it from the
unit. Refer to "Assembly". Apply a coating of oil to the
entire surface of the blade and wrap it in heavy paper,
cloth, or plastic. Also apply a light coat of oil to gear
housing threads, then tighten blade nut securely for
storage,
Reassemble all loose parts, being sure that all handles
and guards are inplace and are securely fastened. Re-
place any aamaged parts_
ENGINE
Never use engine or carburetor cleaner products in the fuel
tank or permanent damage may occur to fuel system com-
ponents,,
Follow these instructions:
1. Drain the fuel from the unit intoan approved
fuel container,
2. Drain the fuel lines and carburetor by starting
the engine and letting it run until it stops.
3. Allow the engine to cool before storage°
IMPORTANT: It isimportantto prevent gum deposits from
forming in essential fuel system parts such as the carbure-
tor, fuel filter, fuel line or tank during storage. Also, experi-
ence indicates that alcohol blended fuels, those that use
ethanol or methanol (called gasohol or oxygenated fuel),
can attract moisture and form acidic gas which will damage
your engine. To avoid engine problems, the fuel system
should be emptied before storage of 30 days or Iongerr
Fuel stabilizer is an acceptable alternative in mini-
mizing the formation of fuel gum deposits during storage.
Add stabilizer to the gasoline in the fuel tank or fuel storage
container. Always follow the mix instructions found on sta-
bilizer container. Run engine at least 5 minutes after ad-
ding stabilizer to allow the stabilizer to reach the carbure-
tor.
Craftsman 40:1 2-cycle engine oil is specially
blended with fuel stabilizers. If you de not use this SEARS
oil, you can add a fuel stabilizer (such as Craftsman
#33500) to your fuel tank.
Remove spark plug and pour 1teaspoon of40:1 oil mix
through the spark plug opening_ Slowly pull the starter
rope 8 to 10 times to distribute oil to inner engine sur-
faces_
Replace spark plug with a new one of the recom-
mended type and heat range Referto "Product Speci-
fications".
•Clean air filter. Refer to"Customer Responsibilities",
° Reinstall all covers and hardware removed for access;
tighten atl screws and fasteners.
•Check entire unit for loose screws, nuts, and bolts, Re-
place any damaged, broken, or worn parts.
• Use fresh fuel having the proper gasoline to oil ratio at
the beginning of the next season.
OTHER
•Do not store gasoline from one season to another.
°Replace your gasoline can if your can starts to rusL
Rust and/or dirt in your fuel system will cause prob-
lems_
•Store your unit in a well ventilated area and covered, if
possible, to prevent dust and dirt accumulation. Do not
cover with plastic. Plastic cannot breathe and will in-
duce condensation and eventual rust or corrosion.
IMPORTANT: Never cover unit while engine and exhaust
areas are still warm.
