. 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 failing tree.
o 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 ten-
sion 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 for-
eign objects that could cause injury or damage to your chain saw.
After striking a foreign object, stop the engine and thor- oughly inspect for damage. Repair as necessary.
Keep the handles dry, clean and free of the oil/fuel mix- ture.
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.
o 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
saw.
,, Always eliminate all sources of sparks or flame in areas
where fuel is mixed or poured.
. Always mix and pour fuel in an outdoor area and use an
approved, marked container for all fuels. Always wipe up all fuel spills before starting saw.
@
When a chain saw is being used, a fire extinguisher
should be available.
o
Always move at least 10 feet (3 meters) from fueling site
before starting saw.
Q
When re-fueling, turn the engine off and allow the saw to
cool in a non-combustible area, do not place on dry
leaves, straw, paper, etc. Slowly remove fuel cap and refuel unit.
Always store the unit and fuel in a cool, dry, well-venti-
lated space where fuel vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, etc.
All chain saw service, other that the items listed in this instruction manual maintenance instructions, should be
performed by a Sears or other qualified service dealer.
Use the right tool. Only use this chain saw for its intend- ed purpose, to cut wood.
Never touch the chain or attempt to service the saw while the engine is running. Make sure all moving parts have stopped. Allow the chain saw to cool, as the chain
can be hot. Check the bar and chain at frequent intervals for proper
adjustment. Make sure the bar and chain are properly tightened and sharpened. Visually inspect for damage.
Repair any damage before restarting or operating the
chain saw.
WARNING: KIOKBA©K 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 con-
tact in some cases may cause a lightning- fast reverse reaction, ktcking the guide bar
up and back towards the operator. Pinching the saw chain along the top of the guide bar
may push the .g.uide 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.

KICKBACK SPECIFICS
WARNING: Kickback can lead to
control of the chain saw and result in serious or fatal injury to the saw operator or to any-
one 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 SPECIFICS Pinch Kickback
Pinch kickback can occur when the saw chain is pinched along the bottom or top of the guide bat:
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.
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 opera-
tor.

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 instruc- tions carefully for the proper fuel/oil mixture.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and oxy_ genates such as ethanol, methanol, or MTBE (ether).
Alcohol-blended fuel absorbs water. As little as 1% water
in the fuel can make fue! and oil separate and lead to for- mation of acids during storage. When using alcohol- blended fuel, use fresh fuel.
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoid- able, follow recommended precautions:
Always use the fresh fuel mix explained in this opera- tor's manual
o Always shake the fuel mix before fueling the unit
Drain the tank and run the engine dry before storing the unit
See Storing Chain Saw in Maintenance and Repair sec- tion
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.

Using Fuel Additives
The bottle of 2-cycle oil that came with your' unit contains a fuel additive which will help inhibit corrosion and mini- mize 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" For proper engine
mum reliability, pay strict attention to the oil and fuel mixing instructions on the 2-cycle oil containelt Using improperly mixed fuel
can severely damage the 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 ft. oz.). Lack of oil will quickly ruin the bar and chain, Too little oil will cause over-
heating with smoke coming from the chain and discol- oration 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 approxi- mately 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 gaso-
line. 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 oi!. 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 thor- oughly mixed. Always read and follow the safety rules
relating to fuel before fueling your unit.
monoxide exhaust fumes can be lethal in a confined area.
WARNING: Never operate the saw
without the bar and chain properly installed,
IMPORTANT:
Gasoline blended with alcohols such as ethanol or
methanol (called gasohol) can attract moisture which leads to separation and formation of acids during stor-
age. 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. See Storing Chain Saw in
Maintenance and Repair section.
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 muf- fler 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.
10
STOPPING INSTRUCTIONS
1, Release the trigger and allow the engine to return to
the idle speed.
2, Move the STOP switch up to the STOP position (Fig. 4).
NOTE; For emergency stopping, push the lever of the
chain brake lever/hand guard (C) forward and move the
STOP switch up (Fig, 3, 4),
STARTING A COLD ENGINE
Be sure to add the correctly mixed fuel to the fuel tank (A) and to add bar and chain oil to the oil tank (B), Make sure the chain brake is disengaged (C) before starting the unit,
1, Slide the STOP switch down (Fig. 4). The red choke
lever (H) has 3 positions: Positions 1, 2 and 3 (Fig. 6),
2. Fully press and release the primer bulb (G) 10 times, slowly. Some amount of fuel should be visible in the
primer bulb (Fig. 5). If you can't see fuel in the bulb, press and release the bulb as many times as it takes
before you can see fuel in it.
3, Move the red choke lever (H) to Position 1 (Fig. 6).
NOTE: This unit will not run with the lever in Position 1,
4. Place the saw on a firm flat surface. Hold saw firmly as shown (Fig. 7).
5. Hold down safety trigger (E)and squeeze the throttle trigger (D), With thumb, press down on the throttle
latch (F). Release trigger (D) first, This will lock the throttle into wide open position (Fig. 3). Pull the rope with a controlled and steady motion 4 times.
NOTE: The unit uses the INCREDI-PULL TM starting system with MAX FIRE IGNITION TM, which significantly
reduces the effort required to start the engine. You must putl the starter rope out far enough to hear the engine attempt to start. There is no need to pull the rope briskly-- there is no harsh resistance when pulling, Be aware that this starting method is vastly different from (and much
easier than) what you may be used to,
6. Then move the red choke lever (H) to Position 2, being sure to keep the throttle trigger locked. Hold saw firmly and pull rope until saw starts. This could take 4 more
pulls.
7. Let the saw warm up for 10 seconds, Depress and release throttle trigger (D) for idle,
8. Move red choke lever (H) to Position 3, Press throttle trigger to begin sawing.
9. If engine fails to start, repeat these instructions. If engine does start, begin chain brake test described on
next page,
10. If unit idles roughly, there is an idle adjustment access hole (L) (Fig, 8), Using a Phillips or flat head screwdriver,
turn screw 1/4 to 1/2 turn clockwise (to the right), Unit should then idle properly (Fig, 9).
NOTE: If chain turns while idling - turn screw back to the left until chain stops and unit continues to idle,

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. The amount of
oil flowing to the bar and chain may be changed by turn-
ing the adjustment screw (D) with a small flat head screw-
driver as shown in Fig. 11. Turn the screw clockwise to
DECREASE oil flow and counterclockwise to INCREASE
the flow,

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 wil! fall.
WARNING: A retreat path (A)

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 notch 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).

LIMBING
First remove the limbs that are not supporting the fallen
tree (A) (Fig, 16) before bucking the tree into shorter length. When removing the non-supporting limbs make
sure that when cut they will not fall towards the operator or the saw, Once the tree has been bucked into shorter
length (see BUCKING), remove the supporting limbs (B), Atl supporting limbs under significant tension (C) should
be cut from the bottom up to avoid binding the saw.
A
When bucking on a slope, always stand on the uphill side.
1. Log supported along entire length: Cut from top (over-
buck), 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 tog 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 diame-
ter 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 tog when cut-
ting on sloping ground. If possible, the log should be sup-
ported 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 posi-
tion 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.

1. Spread chain out in a loop with cutting edges (E, Fig,
24) pointing CLOCKWISE around loop.
2. Slip the chain around the sprocket (F) behind the clutch (G), Make sure the links fit between the sprock-
et teeth (Fig. 25).
3, Place the slotted end of the guide bar over the two
bar bolts (D, Fig. 23), Be sure adjusting tang (J, Fig. 23) is in lower adjusting hole of the bar.
4. Guide the drive links into the groove (H) and around the end of the bar (Fig. 25).
5. The chain will be tight so you will have to rotate the clutch clockwise by gloved hand so the chain engages the bar sprocket.
6. Replace the outer guide bar plate (I)so the bent edges (top and bottom) are directed away from the chain (Fig, 27).
7. lnstall the Chain Brake s cover (C, Fig. 27). Make sure the chain does not slip off of the bar. Install the 2 bat" retaining nuts hand tight and follow instructions in Saw Chain Tension Adjustment.
NOTE: The guide bar retaining nuts are installed only
hand tight at this point because saw chain adjust- ment is required. Follow instructions in Saw Chain
Tension Adjustment.
