RULES FOR SAFE OPERATION
• Avoid accidental starting. Be in the starting position
whenever pulling the starter rope. The operator and unit
must be in a stable position while starting. See
Starting/Stopping Instructions.
• Before you start the engine, make sure the area around
the saw is clear. Never try to start the saw when the
guide bar is engaged in a cut.
• Do not start cutting until you have a clear work area,
secure footing, and a planned retreat path from the
falling tree.
• Do not operate a chain saw that is damaged, improperly
adjusted, or not completely and securely assembled. Be
sure that the saw’s chain stops moving when the throttle
control trigger is released.
• Shut off the engine before setting the chain saw down.
• Use extreme caution when cutting small-sized brush
and saplings because slender material may catch the
chain saw and whip towards you or cause you to lose
control.
• When cutting a limb that is under tension, be alert for
springback so that you will not be struck when the tension in the wood fibers is released.
• Do not cut through nails, rods in the tree, railroad ties or
pallets. Inspect a tree that you are going to cut for foreign objects that could cause injury or damage to your
chain saw.
• After striking a foreign object, stop the engine and thoroughly inspect for damage. Repair as necessary.
• Keep the handles dry, clean and free of the oil/fuel mixture.
• We do not recommend using the chain saw in a tree or
on a ladder.
MAINTAIN YOUR SAW IN GOOD WORKING ORDER
• All chain saw service, other than the items listed in this
instruction manual maintenance instructions, should be
performed by a Sears or other qualified service dealer.
• Make sure all fasteners are in place and secure.
• Unauthorized replacement parts or the removal of safety
devices may cause damage to the unit and possible
injury to the operator or bystanders. Use only Craftsman
accessories and replacement parts as recommended.
Never modify your saw.
• When not in use, saw should be stored in a dry, highly
secure location away from children.
• When storing saw use a scabbard or carrying case.
HANDLE FUEL WITH CAUTION
• Do not smoke while handling fuel or while operating the

tightened and sharpened. Visually inspect for damage.
Repair any damage before restarting or operating the
chain saw.
WARNING:
KICKBACK may
occur when the
nose or tip of the guide bar touches an
object, or when the wood closes in and
pinches the saw chain in the cut. Tip contact in some cases may cause a lightningfast reverse reaction, kicking the guide bar
up and back towards the operator. Pinching
the saw chain along the top of the guide bar
may push the guide bar rapidly back toward
the operator. Either of these reactions may
cause you to lose control of the saw, which
could result in serious personal injury. Do
not rely exclusively upon the safety devices
built into your saw. As a chain saw user,
you should take several steps to keep your
cutting jobs free from accident or injury.
KICKBACK SAFETY PRECAUTIONS
• With a basic understanding of kickback, you can reduce
or eliminate the element of surprise. Sudden surprise
contributes to accidents. Be alert to the potential for
kickback at all times.
• Keep a good firm grip on the saw with both hands, the
right hand on the rear handle and the left hand on the
front handle, when the engine is running. Use a firm grip
with thumbs and fingers encircling the chain saw handles.
A firm grip will help you reduce kickback and maintain
control of the saw. Don’t let go.
4
RULES FOR SAFE OPERATION
• Make sure that the area in which you are cutting is free
from obstructions. Do not let the nose of the guide bar
contact a log, branch, fence, or any other obstruction
that could be hit while you are operating the saw.
• Always cut with the engine running at full speed. Fully
squeeze the throttle trigger and maintain a steady cutting speed.
• Use only the correct original equipment manufacturer
replacement bars, chains and other parts and accessories. These are available from a Sears or other qualified service dealer. Use of any unauthorized parts or
accessories could lead to serious injury to the user, or
damage to the unit, and will void your warranty.
• Follow the manufacturer’s sharpening and maintenance
instructions for the saw chain.
• Use only the replacement guide bars and low kickback
chains specified for your saw to avoid injury.
• Watch for shifting logs or other forces that could pinch
or fall into chain.
• Always have saw at full speed when entering a previous
cut. Always use caution when entering a previous cut.
• Do not start a cut using the tip of the saw.
OTHER SAFETY PRECAUTIONS
• 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.
• Do not operate a chain saw if you are fatigued.
• Use safety footwear; snug-fitting clothing; protective
gloves; and eye, hearing, and head protection devices.
• Do not allow other persons to be near the chain saw
when starting or cutting with the chain saw. Keep
bystanders and animals out of the work area.
• Do not remove, damage or de-activate any of the safety
devices. Never use a damaged, modified, or improperly
repaired or assembled chain saw. Check their proper
operation regularly. Only use bars and chains of the
length indicated in the table herein.

RULES FOR SAFE OPERATION
KICKBACK SPECIFICS
WARNING:
control of the chain saw and result in serious
or fatal injury to the saw operator or to anyone standing close by. Always be alert.
Rotational kickback and pinch-kickback are
major chain saw operational dangers and the
leading cause of most accidents.
KICKBACK may occur when the NOSE or TIP of the
guide bar touches an object, or when wood closes in and
pinches the saw chain in the cut.
Tip contact in some cases may cause a lightning-fast
reverse reaction, kicking the guide bar up and back
toward the operator.
Any of these reactions may cause you to lose control of
the saw, which could result in serious personal injury.
Kickback can lead to
dangerous loss of
Rotational Kickback
Rotational Kickback can occur when the moving
chain contacts an object at the upper tip of the guide
bar. This contact can cause the chain to dig into the
object, which stops the chain for an instant. The
result is a lightning fast, reverse reaction which kicks
the guide bar up and back toward the operator.
KICKBACK SPECIFICS
Pinch Kickback
Pinch kickback can occur when the saw chain is pinched
along the bottom or top of the guide bar.
When pinched on the bottom of the guide bar, it may pull
the saw forward, away from the operator
When pinched along he top of the guide bar, it may push
the guide bar rapidly back toward the operator.

OIL AND FUEL INFORMATION
OIL AND FUEL MIXING INSTRUCTIONS
Old and/or improperly mixed fuel are the main reasons for
the unit not running properly. Be sure to use fresh (less
than 60 days old) clean unleaded fuel. Follow the instructions carefully for the proper fuel/oil mixture.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and oxygenates such as ethanol, methanol, or MTBE (ether).
Alcohol-blended fuel absorbs water. As little as 1% water
in the fuel can make fuel and oil separate and lead to formation of acids during storage. When using alcoholblended fuel, use fresh fuel.
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoidable, follow recommended precautions:
• Always use the fresh fuel mix explained in your operator's manual
• Always shake the fuel mix before fueling the unit
• Drain the tank and run the engine dry before storing the
unit
Using Fuel Additives
The bottle of 2-cycle oil that came with your unit contains
a fuel additive which will help inhibit corrosion and minimize the formation of gum deposits. It is recommended
that you use our 2-cycle oil with this unit.
If unavailable, use a good 2-cycle oil designed for
air-cooled engines along with a fuel additive, such as
STA-BIL®Gas Stabilizer or an equivalent. Add 0.8 oz.
(23 ml.) of fuel additive per gallon of fuel according to the
instructions on the container. NEVER add fuel additives
directly to the unit's fuel tank.
CAUTION:
mum reliability, pay strict attention to the oil
and fuel mixing instructions on the 2-cycle
oil container. Using improperly mixed fuel
can severely damage the engine.
For proper engine
operation and maxi-
To Obtain Correct Fuel Mix:
Thoroughly mix the proper ratio of 2-cycle engine oil with
unleaded gasoline in a separate fuel can. Use a 40:1
fuel/oil ratio. Do not mix them directly in the engine fuel
tank. See the table below for specific gas and oil mixing
ratios.
NOTE: One gallon (3.8 liters) of unleaded gasoline mixed
with one 3.2 oz. (95 ml.) bottle of
2-cycle oil makes a 40:1 fuel/oil ratio.

STARTING/STOPPING INSTRUCTIONS
Operate this unit only
WARNING:
in a well-ventilated
outdoor area. Carbon
monoxide exhaust fumes can be lethal in a
confined area.
Never operate the saw
WARNING:
without the bar and
chain properly
installed.
BEFORE STARTING ENGINE
WARNING: Be sure to read the Oil and Fuel Information
Section of this manual before you begin. If you do not
understand the oil and fuel information, do not attempt
to fuel your unit. For more information contact your
local Sears service center at 1-800-4-MY-HOME®.
GUIDE BAR AND CHAIN OIL
The bar and chain require lubrication. The chain oiler
provides continuous lubrication to the chain and guide
bar. Be sure to fill the bar oil tank when you fill the fuel
tank. (Capacity = 6.8 fl. oz.). Lack of oil will quickly
ruin the bar and chain. Too little oil will cause overheating with smoke coming from the chain and discoloration of the bar. 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 the
Craftsman brand. The oil output is automatically
metered during operation. Your saw will use approximately one tank of bar oil for every tank of fuel mix.
Always fill the bar oil tank when you fill the fuel tank.
FUELING THE ENGINE
WARNING: Remove fuel cap slowly when refueling.
This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a
good quality synthetic 2-cycle air-cooled engine oil.
We recommend Craftsman brand synthetic oil. Mix
gasoline and oil at a ratio of 40:1. 40:1 ratio is
obtained by mixing 3.2 ounces of oil with 1 gallon of
unleaded gasoline. Included with this saw is a 3.2
ounce container of oil. Pour the entire contents of this
container into one gallon of gasoline to achieve the
proper fuel mixture. DO NOT use automotive oil or
boat oil. These oils will cause engine damage. When
mixing fuel, follow the instructions printed on the oil
container. Once oil is added to the 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 with fuels
(called gasohol or 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 when in storage. To avoid
engine problems, the fuel system should be emptied
before storage for 30 days or longer. Drain the gas
tank, start the engine and let it run until fuel lines and
carburetor are empty. Use fresh fuel next season.
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage can occur. See STORAGE instructions for additional information.
CHAIN BRAKE
Be sure the chain brake is disengaged by pulling the
front hand guard back toward the front handle as far
as possible. The chain brake must be disengaged
before cutting with the saw.
WARNING: The chain brake must not move when the
engine runs at idle speed. If the chain brake moves at
idle speed, refer to CARBURETOR ADJUSTMENT in
this manual. Avoid contact with the muffler. A hot muffler can cause serious burns.
IMPORTANT POINTS TO REMEMBER
When pulling the starter rope, do not use the full
extent of the rope as this can cause the rope to break.
Do not let starter rope snap back. Hold the handle and
let the rope rewind slowly. For cold weather starting,
start the unit at FULL CHOKE; allow the engine to
warm up before squeezing the throttle trigger.
DO NOT attempt to cut material with the choke/fast idle
lever in the FULL CHOKE position.

Chain Lubrication
Adequate lubrication of the saw chain is essential at all
times to minimize friction with the guide bar. Never starve
the bar and chain of oil. Running the saw with too little oil
will decrease cutting efficiency, shorten saw chain life,
cause rapid dulling of chain, and cause excessive wear of
bar from overheating. Too little oil is evidenced by smoke,
bar discoloration or pitch build-up.
Automatic Oiler
Your chain saw is equipped with an automatic gear driven
oiler system. The oiler automatically delivers the proper
amount of oil to the bar and chain. As the engine speed
increases, so does the oil flow to the bar pad. The amount
of oil flowing to the bar and chain may be changed by
turning the adjustment screw (D) with a small slotted
screwdriver as shown in Fig. 11. Turn the screw clockwise
to DECREASE oil flow and counterclockwise to INCREASE
the flow.

OPERATING INSTRUCTIONS
FELLING
Felling is the term for cutting down a tree. Small trees up
to 6-7 inches (15-18cm) in diameter are usually cut in a
single cut. Larger trees require notch cuts. Notch cuts
determine the direction the tree will fall.
WARNING:
and cleared as necessary before cuts are
started. The retreat path should extend back
and diagonally to the rear of the expected
line of fall, as illustrated in Fig. 12.
CAUTION:
chain saw operator should keep on the
uphill side of the terrain, as the tree is likely
to roll or slide downhill after it is felled.
NOTE: Direction of fall (B) is controlled by the notching
cut. Before any cuts are made, consider the location of larger branches and natural lean of the tree
to determine the way the tree will fall.

lengths away from your fellow workers.
Make the felling cut (D) from the other side of the tree and
1.5 - 2.0 inches (3-5 cm) above the edge of the notch (C)
(Fig. 13).

Never saw completely through the trunk. Always leave a
hinge. The hinge guides the tree. If the trunk is completely
cut through, control over the felling direction is lost.
WARNING:

Insert a wedge or felling lever in the cut well before the
tree becomes unstable and starts to move. This will prevent the guidebar from binding in the felling cut if you
have misjudged the falling direction. Make sure no
bystanders have entered the range of the falling tree
before you push it over.
Never walk in front of

WARNING:
changing winds or if there is a danger to
property. Consult a tree professional.Do not
cut down a tree if there is a danger of striking utility wires; notify the utility company
before making any cuts.
Normally felling consists of 2 main cutting operations,
notching (C) and making the felling cut (D) (Fig. 13).
Start making the upper notch cut (C) on the side of the
tree facing the felling direction (E). Be sure you don t make
the lower cut too deep into the trunk (Fig. 13).
The notch (C) should be deep enough to create a hinge (F)
of sufficient width and strength. The notch should be wide
enough to direct the fall of the tree for as long as possible
(Fig. 13).
Do not cut down a
tree during high or
Felling Cut:
1. Use wooden or plastic wedges (G) to prevent binding
the bar or chain (H) in the cut. Wedges also control
felling (Fig. 14).
2. When diameter of wood being cut is greater than the
bar length, make 2 cuts as shown (Fig. 15).
As the felling cut
gets close to the

LIMBING
Limbing a tree is the process of removing the branches
from a fallen tree. Do not remove supporting limbs (A) until
after the log is bucked (cut) into lengths (Fig. 16).
Branches under tension should be cut from the bottom up
to avoid binding the chain saw.
When bucking on a slope, always stand on the uphill side.
1. Log supported along entire length: Cut from top (overbuck), being careful to avoid cutting into the ground
(Fig. 17).
2. Log supported on 1 end: First, cut from bottom
(underbuck) 1/3 diameter of log to avoid splintering.
Second, cut from above (overbuck) to meet first cut
and avoid pinching (Fig. 18).
3. Log supported on both ends: First, overbuck 1/3 diameter of log to avoid splintering. Second, underbuck to
meet first cut and avoid pinching (Fig. 19).
NOTE: The best way to hold a log while bucking is to use
a sawhorse. When this is not possible, the log
should be raised and supported by the limb
stumps or by using supporting logs. Be sure the
log being cut is securely supported.

BUCKING
Bucking is cutting a fallen log into lengths. Make sure you
have a good footing and stand uphill of the log when cutting on sloping ground. If possible, the log should be supported so that the end to be cut off is not resting on the
ground. If the log is supported at both ends and you must
cut in the middle, make a downward cut halfway through
the log and then make the undercut. This will prevent the
log from pinching the bar and chain. Be careful that the
chain does not cut into the ground when bucking as this
causes rapid dulling of the chain.

BUCKING USING A SAWHORSE
For personal safety and ease of cutting, the correct position for vertical bucking is essential (Fig. 20).
A. Hold the saw firmly with both hands and keep the saw
to the right of your body while cutting.
B. Keep the left arm as straight as possible.
C. Keep weight on both feet.
CAUTION:
