KNOW YOUR SAW
• Read your operator's manual carefully until you completely understand and can follow all safety rules, precautions, and operating instructions before attempting to
operate the unit.
• Restrict the use of your saw to adult users who understand and can follow safety rules, precautions, and operating instructionsfound in this manual.
PLAN AHEAD
• Wear protective gear. Figure 1. Always use steel-toed
safety footwear with non-slfp soles; snug-fitting clothing;
heavy-duty, non-slip gloves, eye protection such as
non-fogging,
vented goggles Or face screen; an
approved safety hard hat; and sound barriers - ear
plugs or mufflers to protect your hearing. Regu,ar users
should have hearing checked regularly as chain saw
noise can damage hearing.
• Keep all parts of your body away from the chain
when the engine is running.
* Keep children, bystanders, and animals a minimum
of 30 feet (10 meters) away from the work area. Do
not allow other people or animals to be near the chain
saw when starting or operating the chain saw.
• Do not handle or operate a chain saw when you are
fatigued, ill, or upset, or if you have taken alcohol,
drugs, or medication. You must be in good physical
condition and mentally alert. Chain saw work is strenuous. If you have any condition which might be aggravated
by strenuous work, check with your doctor before operating a chain saw.
• Do not attempt to use your chain saw during bad
weather conditions such as strong wind, rain, snow, ice,
etc., or at night.
• Carefully plan your sawing operation in advance.Do
not start cutting until you have a clear work area, secure
footing, and, if you are felling trees, a planned retreat
path.
• Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Always replace the handguard immediately if it
becomes damaged, broken, or is otherwise removed.
• Keep the handles dry, clean, and free of oil or fuel
mixture.
• With the.engine stopped, hand cam/the chain saw
with the muffler away from your body, and the guide
bar and chain to the rear, preferably covered with a
scabbard.
HANDLE FUEL WITH CAUTION
• Eliminate all sources of sparks or flame in the areas
where fuel is mixed, poured, or stored. There should
be no smoking, open flames, or work that could cause
sparks.
• Mix and pour fuel in an outdoor area, on bare
ground; store fuel in a cool, dry, well-ventilated
place; and use an approve, marked container for fuel.
• Wipe up all spilled fuel before starting your saw.
• Move at least 10 feet (3 meters) away from fuel and
fueling site before starting the engine.
• Do not smoke while handling fuel or while operating
the saw.
• Turn the engine off and let your saw cool in a noncombustible area, not on dry leaves, straw, paper, etc.
Stowly remove fuel cap and refuel unit.
• 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
SAFETY NOTICE
Exposure to vibrations through prolonged use of gasoline powered hand units could cause blood vessel or nerve damage in the fingers, hands, and wrists of people prone to circulation disorders or abnormal swellings. Prolonged use in cold weatherhas been linked to blood vessel damage in otherwise healthy people. If
symptoms occur such as numbness, pain. loss of strength, change in skin color or texture, or loss of feeling in the fingers, hands or wrists, discontinue the use of
this unit and seek medical attention.An anti-vibrationsystem does not guaranteethe avoidanceof these problems. Users who operate power tools on a continual
_nd regular basis must monitor closely their physical condition and the conditionof this tool.

OPERATE YOUR SAW SAFELY
MAINTAIN YOUR SAW IN GOOD
• Do not operate a chain saw with one hand. Serious
injury to the operator, helpers, bystanders or any combination of these persons may result from one-handed
operation. A chain saw is intended for two-handed use.
WORKING
• Operate the chain saw only in outdoor areas.
• Do not operate saw from a ladder or in a tree, unless
specifically trained to do so.
• Position all parts of your body to the left of cut and
away from the saw chain when the engine is running.
• Cut wood only. Do not use your saw to pry or shove
away limbs, roots, or other objects.
• Make sure the chain will not make contact with any
object while starting the engine. Never try to start the
saw when the guide bar is in a cut or kerr.
• Use extreme caution when cutting small size brush
and saplings. Slender material can catch the saw chain
and be whipped toward you or pull you off balance.
• Be alert for springback when cutting a limb that is
under tension so you will not be struck by the limb or saw
when the tension in the wood fibers is released.
• Do not put pressure on the saw at the end of a cut.
Applying pressure can cause you to lose control when
the cut is compJeted.
• Stop the engine before setting the saw down.
• Keep fuel and oil caps, screws, and fasteners
securely tightened.

ORDER
• Have all chain saw service performed by your Sears
Service Center with the exception of the items listed in
the customer responsibilities section of this manual. For
example, if improper tools are used to remove or hold the
flywheel when servicing the clutch, structural damage to
the flywheel can occur and cause the flywheel to burst.
• Make certain the saw chain stops moving when the
throttle trigger is released. For correction, refer to
,'Carburetor Adjustments."
• Stop the saw if the chain strikes a foreign object.
Inspect the unit and repair or replace parts as necessary.
• Disconnect the spark plug before performing any
maintenance except for carburetor adjustments.
• Never modify your saw in any way. Use only attachments supplied or specifically recommended by the manufacturer.
TRANSPORTING
AND STORAGE
• Stop the unit before transporting.
• Allow the engine to cool, cover the bar and chain, and
secure the unit before storing or transporting in a vehicle.
• Empty the fuel tank before storing or transporting the
unit. Use up any fuel left in the carburetor by starting the
engine and letting the engine run until it stops.
• Store unit and fuel in an area where fuel vapors cannot
reach sparks or open flames from water heaters, electric
motors or switches, furnaces, etc.
• Store unit so the chain cannot accidentally cause injury.
• Store the unit out of the reach of children.

FEATURES
REACTIVE
FORCES
Pinch-Kickback and Pull-In occur when the chain is
suddenly stopped by being pinched, caught, or by contacting a foreign object in the wood. This sudden stopping of the chain results in a reversal of the chain force
used to cut wood and causes the saw to move in the opposite direction of the chain rotation, Either reaction can result
in loss of control and possible serious injury.
• Pinch-Kickback
- occurs when chain on top of guide bar is suddenly
stopped.
- rapidly drives saw straight back toward operator.
° Pull-In
- occurs when the chain on the bottom of the guide
bar is suddenly stopped.
- pulls the saw rapidly forward,

• Handguard, designed to reduce the chance of your left
hand contacting the chain if your hand slips off the front
handlebar.
• Position front and rear handlebars, designed with distance between handles and "in-line" with each other. The
spread and "in-line" position of the hands provided by this
design work together to give balance and resistance in
controlling the pivot of the saw back toward the operator
if kickback occurs.

THROTTLE
TRIGGER
& LOCKOUT
(Fig. 19)
• The throttle trigger controls engine speed. At idle, a
centrifugal clutch automatically disengages the chain.
• The throttle lockout prevents unintentional activation of
the throttle trigger. Also, the throttle lockout must be
depressed
before
the throttle
trigger
can be
depressed.

CUTTING
TECHNIQUES
USE/TIPS
• Cut wood only. Do not cut metal; plastics; masonry;
men-wood building materials; etc.
• Stop the saw if the chain strikes a foreign object.
Inspect the saw and repair or replace parts as necessary.
• Keep the chain out of dirt and sand. Even a small
amount of dirt will quickly dull a chain and thus
increase the possibility of kickback.
To get the "feel" of using your saw before you begin a
major sawing operation, practice cutting a few small logs
using the following technique:
• Accelerate engine to full throttle before entering cut by
squeezing the throttle trigger.
• Begin cutting with the saw frame against the tog.
- Keep.engine at full throttle during cutting procedure.
° Allow the chain to cut for you; exert only light downward pressure. If you force the cut, damage to the bar,
chain, or engine can result.
• Release the throttle trigger as soon as the cut is completed, allowing the engine to idle. If you run the unit at
full throttle without cutting, unnecessary
wear can
occur to the chain, bar, and engine.
°
To avoid losing control when completing the cut, do
not put pressure on the saw during the end of the cut.
Stop engine before setting unit down after operation.
(Fig. 20 & 21)
• Overcutting - begin on the top side of the log with the
bottom of the saw against the log; exert light pressure
downward.
• Undercutting - begin on the under side of the tog with
the top of the saw against the log; exert light pressure
upward. During undercutting, the saw will tend to push
back at you. Be prepared for this reaction and hold the
saw firmly to maintain control.

GENERAL
SAFETY
AVOID REACTIVE
Pinch-Kickback
WARNING:
IF SAW BECOMES PINCHED OR HUNG IN A
LOG, DO NOT TRY TO FORCE IT OUT. YOU
CAN LOSE CONTROL
OF THE SAW
RESULTING IN INJURY AND/OR DAMAGE
TO THE SAW. STOP THE SAW, DRIVE A
WEDGE OF PLASTIC OR WOOD INTO THE
CUT UNTIL THE SAW CAN BE REMOVED
EASILY.
RESTART
THE SAW AND
CAREFULLY
RE-ENTER THE CUT. TO
AVOID KICKBACK AND CHAIN DAMAGE,
DO NOT USE A METAL WEDGE. DO NOT
ATTEMPT
TO RE-START
YOUR SAW
WHEN IT IS PINCHED OR HUNG IN A LOG.
KICKBACK
CAN OCCUR WHEN THE
MOVING CHAIN CONTACTS AN OBJECT
AT THE UPPER PORTION OF THE TIP OF
THE GUIDE BAR OR WHEN THE WOOD
CLOSES IN AND PINCHES THE SAW CHAIN
IN THE CUT. CONTACT AT THE UPPER
PORTION OF THE TIP OF THE GUIDE BAR
CAN CAUSE THE CHAIN TO DIG INTO THE
OBJECT AND STOP THE CHAIN FOR AN
INSTANT. THE RESULT IS A LIGHTNING
FAST, REVERSE REACTION WHICH KICKS
THE GUIDE BAR UP AND BACK TOWARD
_THE OPERATOR. IF THE SAW CHAIN IS
PINCHED ALONG THE TOP OF THE GUIDE
BAR, THE GUIDE BAR CAN BE DRIVEN
RAPIDLY BACK TOWARD THE OPERATOR. EITHER OF THESE REACTIONS CAN
CAUSE LOSS OF SAW CONTROL WHICH
CAN RESULT IN SERIOUS INJURY.
PINCH FORCES
and Pull-in occur when the chain is sud-
denly stopped by being pinched, caught, or by contacting a foreign object in the wood. This sudden stopping of
the chain results in a reversal of the chain force used to
cut wood and causes the saw to move in the opposite
direction of the chain rotation. Pinch-Kickback drives the
saw straight back toward the operator. Pull-In pulls the
saw away from the operator. Either reaction can result in
loss of control and possibly serious injury.
TO AVOID PINCH-KICKBACK:
• Be extreme_ aware of situations or obstructions that
can cause material to pinch the top of or otherwise
stop the chain.
° Do not cut more than one log at a time.
° do not twist the saw as the bar is withdrawn from an
under-cut when bucking.

THEY CAN FALL UNEXPECTEDLY AND
CAUSE SERIOUS INJURY.
AS YOU MAKE YOUR FELLING CUT, IF
THE SAW APPEARS TO BE BINDING,
THE TREE IS STARTING
TO FALL IN
THE WRONG DIRECTION. iMMEDIATELY
STOP THE SAW AND USE A FELLING
WEDGE
AND MAUL (HAMMER)
TO
FORCE THE FELLING CUT OPEN. THE

• Wind - A tree evenly balanced will fatl in the same direction the wind is blowing.
• Lean - Use a carpenter's level or ptumb bobto determine
if tree has a natural lean. A leaning tree will tend to fal! in
direction of lean.
• Shape - A tree will tend to fall towards side that is more
heavily branched.
• Other Factors - Contacting or nearby trees, buildings, or
wires can influence the direction the tree will fall.

After determining the Natural Fa_l Direction, the tree should
be cut as follows:
IMPORTANT:BEFORE FELLING A TREE, MAKE SURE
YOU HAVE AT LEAST 3 FELLING WEDGES AND A
MAUL (HAMMER) AVAILABLE FOR USE IF NEEDED.
• Use some means to visually mark the Natural Fall
Direction.
• Mark your notch cut on the Natural Fall Direction side of
the tree approximately 18-24 inches above the ground.
• Cut top of the notch first at a 45 degree angle. Saw
through 1/3 of the width of the tree.
• Cut bottom of the notch at a 45 degree angle until you
meet the top notch cut. Remove notch of wood.
• On the side of the tree opposite the notch cut, make the
telling cut. The felling cut should be 2 inches above the
center point of the notch cut. Before the felling cut is
complete, use wedges to open the cut when necessary to
control the direction of the fall. Use wood or plastic
wedges, buI never steel or iron, to avoid kickback and
chain damage.
• Cracking sounds, widening of the felling cut, movement
in the upper branches are all signs that the tree is ready
to fall
.
• As tree begins to fall, move ON/STOP switch to "Stop"
position, set it down, and move quickly away from
direction of fall.
If your chain saw binds in the felling cut, you have three
options:
• If the wrong direction of fall is acceptable, carefully
remove the felling wedge. Cut deeper in the notch side of
the tree until tree starts to fall.
-12-
Figure 22
• If the wrong direction of fall is not acceptable, attempt to
use one or more felling wedges to force the tree in the
original direction of fal!. Do so by driving the wedges
deeper into the felling cut.
• Keep everyone away from the tree in aFIdirections and
then seek professional help!
NOTE: For trees less than 6 inches in diameter, make a
single feilingcut on the side away from the direction of fall.
Cut through until tree begins to fall. Then turn off saw, set it
down, and move quickly away from direction of fall.
OPERATION
USE/TIPS
• Clear the work area of debris where you can have secure
footing.
• Make sure there is enough room for the tree to fall.
Maintain a distance of 2 !/2 tree lengths from the nearest
person or other objects. Engine noise can drown out a
warning call.
• Remove dire, stones, loose bark, nails, staples, and wire
from the tree where cuts are to be made.
• Plan to stand on the up-HI side when cutting on a slope.
° Plan a clear retreat path to the rear and diagonal to the
line of fall.
• If unsure about which way a tree will fal!, use the notch
cutting method.
• Large buttress roots should be removed prior to notch
cut.
, Use a wedge if there is any chance that the tree will not
fall in the desired direction.
• We recommend you cut branches below shoulder height
before felling tree. (See Limbing and Pruning).

Another log or a stand, such as a sawhorse, may be
used as supports when bucking.
• Area A- Undercut 1/3 of the way through the log.
- Finish with an overcut.
• Area B - Overcut 1/3 of the way through the log.
- Finish with an undercut.
Bucking is cutting a fallen tree to the desired log size.
TYPES
OF CU'I-rlNG
(Fig. 23)
• Overcutting - begin on the top side of the log with the
bottom of the saw against the log; exert light pressure
downward.
• Undercutting - begin on the under side of the log with
the top of the saw against the log; exert light pressure
upward. During undercutting, the saw will tend to push
back at you. Be prepared for this reaction and hold the
saw firmly to maintain control.

OIL
For maximum guide bar and chain life, we recommend
you use Craftsman chain saw bar oil. If Craftsman bar
oil is not available, you may use a good grade SAE 30
oil until you are able to obtain Craftsman brand. The oil
output is automatically metered during operation. Your
saw will use one tank of bar oil for every tank of fuel mix.
Always fill the bar oil tank when you fill the fuel tank.

STABILIZER
Fuel stabilizer is an acceptable alternative in minimizing
the formation of fuet gum deposits during storage. Add
stabilizer to gasoline in fuel tank or storage container.
Always follow the fuel mix ratio found on the stabilizer
container, run engine at least 5 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. You
do not have to drain the fuel tank for storage if you are
using fuel stabilizer.
CRAFTSMAN 40:1 2-cycle AIR-COOLED engine oil is
specially blended with fuel stabilizers. If you do not use
this Sears oil, you can add a fuel stabilizer (such as
Craftsman No. 33500) to your fuel tank.
40:1 2-CYCLE
AIR-COOLED
ENGINE
OIL:
CRAFTSMAN 40:1 2-cycle AIR-COOLED engine oil 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 40:1 2-cycle AIR-COOLED engine oi! is
not available, use a good quality 40:1 2-cycle AiRCOOLED engine oi_ that has a recommended fuel mix
ratio of 40:1.
IMPORTANT! Do not use:
GASOLINE
The two-cycle engine on this product requires a fuel mixture of regular unleaded gasoline and a high quality 40:1
2-cycle AIR-COOLED
engine oil for lubrication of the
bearings and other moving parts. The correct fueVoi!
m_xture is 40:1 _see Fue! Mixture Chart). Too little oil- or
the incorrect oil type will cause poor performance and
may cause the engine to overheat and seize.
Gasoline and oil must be premixed in a clean approved
fuel container. Always use fresh regular unleaded gasoline.
* AUTOMOTIVE OIL
. BOAT OILS (NMMA, BIA etc.)
These oils do not have proper additives for 2-cycle AIRCOOLED 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 directty in the unit's fuel
tank.
This engine is certified to operate on unleaded gasoline.
IMPORTANT: Experience indicates that alcohol blended
fuels called gasohol (or using ethanol or methanol) can
attract moisture, which leads to oil/gas separation and
formation of acids during storage. Acidic gas can damage the fue! 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.
FOR ONE GALLON:
° Pour 3.2 ounces of high quality, 40:1 2-cycted AIRCOOLED engine oil into an empty, approved one gallon
gasoline container.
• Add one galion of regular unleaded gasoline to the
gallon container, then securely replace the cap.
• Shake the container.
• The mixture is now ready for use. Fuel stabilizer can be
added at this time if desired; follow mixing instructions
on the label.

ADJUSTMENTS
Carburetor adjustment is critical and if done improperly can permanently damage the engine as well as the carburetor. Please read all instructions and consultthe Troubleshooting section of this manual before beginning
this process.
If the engine does not start, it may be flooded. If in
doubt, read the section on flooded engine in the starting
section of this manual prior to beginning any adjustments.
If you are unsure about adjusting the carburetor or experience any problem while attempting this process, please
call the 1-800 number listed on the front cover of this
manual for further assistance.
The carburetor has been adjusted at the factory for sea
level conditions. Adjustments may become necessary if
the unit is used at significantly higher altitudes or if you
notice any of the following conditions:
° Chain moves when.the engine runs at idle speed. See
"Idle Speed Adjustment."
• Saw will not idle. See "Idle Speed Adjustment" and
"Low Speed Mixture Adjustment."
• Engine dies or hesitates when it should accelerate.
See "Acceleration Adjustment."
• Loss of cutting power which is not corrected by air filter
cleaning. See "High Speed Mixture Adjustment."
CARBURETOR
CAUTION:
DO NOT TURN SCREWS TOO TIGHT;
THIS WILL RESULT IN DAMAGE TO
NEEDLE TIPS AND NEEDLE SEATS.
IF CHAIN MOVES WHEN ENGINE IDLES,
TURN IDLE SPEED SCREW COUNTERCLOCKWISE UNTIL CHAIN STOPS.
° Turn

• Turn
THE CHAIN WILL BE MOVING DURING
MOST OF THIS PROCEDURE.
WEAR
YOUR PROTECTIVE EQUIPMENT AND
OBSERVE ALL SAFETY PRECAUTIONS.
(Fig. 58)
Very small adjustments can affect engine performance.
It is important to turn the screw a very small amount per
adjustment and test performance before making further
adjustments. Each adjustment should be no more than
the width of the slot in the adjusting screw.
NOTE: Do not attempt to adjust the screw beyond the
stops as damage can occur.
WARNING:
PRESETS
If your engine will not start due to suspected improper
carburetor adjustment, the following presets may be
required. If used, it is recommended that all steps within
the adjustment
procedure be completed in order to
assure a propedy set carburetor. If presets are not needed, proceed to section "tdle Speed Adjustment."

• Allow the warn engine to idle.
• Adjust idle speed screw 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 engine down
and/or to keep the chain from turning.
• No further adjustments are necessary if the chain does
not move at idle speed and if performance is satisfactory.
LOW SPEED MIXTURE ADJUSTMENT
• Allow engine to idle.
• Turn the Low Speed Mixture Screw slowly clockwise until
the RPM starts to drop. Note the position.
• Turn the Low Speed Mixture Screw slowly counterclockwise until the RPM speeds up and starts to drop again,

• Set the Low Speed Mixture Screw at the midpoint
between the two positions,
HIGH SPEED MIXTURE ADJUSTMENT
IMPORTANT:DO
NOT OPERATE ENGINE AT FULL
THROTTLE
FOR PROLONGED
PERIODS WHILE
MAKING HIGH SPEED ADJUSTMENTS AS DAMAGE
TO THE ENGtNE CAN OCCUR.
• Make a test cut.
• Based on performance of the saw while cutting, adjust
the High Speed Mixture Screw in 1/16 turn increments
as follows:
- Clockwise ff saw smokes or loses power in the cut.
Do not adjust for best power by sound or speed, but
judge by how well the saw performs in the cut.
- Counterclockwise if the saw has speed while out of the
cut, but dies in the cut or lacks poser while cutting,
• Repeat the test cut.
• Continue with 1/16 turn adjustments until the saw
performance is acceptable while cutting.
° After completing adjustments, check for acceleration.
ACCELERATION CHECK
• If the engine dies or hesitates instead of accelerating,
turn the Low Speed Mixture Screw 1/16 of a turn at a
time counterclockwise until you have smooth acceleration.
• Check the idle speed for stability and no chain movement, Adjust as necessary.
° Recheck for smooth acceleration
and stable idle.
Repeat
process
as necessary
for acceptable
performance.
- 26 -
A CARBURETOR SETTING THAT IS TOO
LEAN (CLOCKWISE
ADJUSTMENT
ON
HIGH SPEED SCREW FOR MAXIMUM
SPEED) WILL CAUSE ENGINE DAMAGE
TO ANY 2-CYCLE ENGINE FROM OVERHEATING AND LACK OF LUBRICATION.
NEVER SET THE HIGH SPEED SCREW
SO FAR CLOCKWISE THAT YOU HAVE
ENGINE SPEED LACKING POWER TO CUT.
AN EFFECTIVE APPROACH FOLLOWS:
- TURN HIGH SPEED SCREW COUNTERCLOCKWISE UNTIL ENGINE LOSES
POWER WHILE CUTTING.
-TURN
HIGH SPEED SCREW CLOCKWISE USING 1/16 TURN INCREMENTS
ONLY UNTIL THE ENGINE HAS POWER
WHILE CUTTING.

FUEL SYSTEM
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur to fuel system components.
Follow these instructions:
• Drain the fuel from the unit into an approved fuet container.
• Drain the fuel lines and carburetor by starting the
engine and letting it run until it stops.
• Allow the engine to coot before storage.
IMPORTANT: It is important to prevent gum deposits
from forming in essential fuel system parts such as the
carburetor, fuel filter, fuel hose or tank during storage.
Also, experience 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 longer.
Immediately prepare your unit for storage at the end of
the season or if it will not be used for 30 days or more.
WARNING:
ALLOW THE ENGINE TO COOL, AND
SECURE THE UNIT BEFORE STORING
OR TRANSPORTING IN A VEHICLE.
STORE UNIT AND FUEL IN AN AREA
WHERE FUEL VAPORS CANNOT REACH
SPARKS
OR OPEN FLAMES
FROM
WATER HEATERS, ELECTRIC MOTORS
OR SWITCHES, FURNACES, ETC.
Fuel stabilizer is an acceptable alternative in minimizing
the formation of fuel gum deposits during storage. Add
stabilizer to the gasoline in the fuel tank or fuel storage
container. AIways follow the mix instructions found on
stabilizer containers. Run engine at least 5 minutes after
adding stabilizer to allow the stabilizer to reach the carburetor.
CRAFTSMAN 40:1 2-cycle AIR-COOLED engine oil is
specially blended with fuel stabilizer. If you do not use
this Sears oil, you can add a fuel stabilizer (such as
CRAFTSMAN No. 33500) to your fuel tank.
