SAFETY RULES
OPERATE YOUR SAW SAFELY
• Do not operate a chain saw with one hand. Serious
injury to the operator, helpers, bystanders or any combina
tion of these persons rray result from one-handed opera
tion. A chain saw is intended for two-handed use.
• Oper^e flie chain saw only in well-ventifated 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 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 white starting the engine. Never try to start the
saw when the guide bar is in a cut or kerf.
' Use extreme caution when cutting small size brush
and saplings. Slender material can catch the 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
Aiplying pressure can cause you to lose control when the
cut is completed.
Stop ihe engine before setting the saw down.
Keep fuel and oil caps, screws, and fasteners securely
tightened.
MAINTAIN YOUR SAW IN GOOD WORKING 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 f^iwheel to burst.
• Make certain tiie 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 unit and repair or replace parts as necessaiy.
• Disconnect tfie spark plug before performing any
maintenance except for carburetor adjustrrwnts.
• Never modify your saw in any way. Use only SEARS '
accessories and replacement parts as recxDmrnended.
TRANSPORTING AND STORAGE
• stop the unit before transporting.
• Allow engirie to cool, cover the guide bar and chain, and
secure the unit before storing or trareporting in a trehide.
• Empty ftjel lank before storing or transporting tte unit. Use
up any fuel left in the carburetor by starting the engine and
letting ti^ 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 acddentally cause injury,
• Store the unit out of the reach of children.
GUARD AGAINST KICKBACK - Kickback is a dangerous reaction that can lead to serious injury.
KICKBACK WARNING;
A
KICKBACK CAN OCCUR WHEN THE MOV
ING CHAIN CONTACTS AN OBJECT AT THE
UPPER PORTION OFTHETIP OFTHE GUIDE
BAR OR WHEN THE WOOD CLOSES IN AND
PINCHES THE 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, 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, IF THE
CHAIN IS PINCHED ALONG THE TOP OF
THE GUIDE BAR, THE GUIDE BAR CAN BE
DRIVEN RAPIDLY BACK TOWARD THE
OPERATOR. EITHER OFTHESE REACTIONS
CAN CAUSE LOSS OF SAW CONTROL
WHICH CAN RESULT IN SERIOUS INJURY.
DO NOT RELY ONLY ON THE SAFETY
DEVICES PROVIDED WITH YOUR SAW. AS
A CHAIN SAW USER, YOU MUST TAKE
SPECIAL SAFETY PRECAUTIONS TO HELP
KEEP YOUR CUTTING JOBS FREE FROM
ACCIDENT OR INJURY.

REDUCE THE CHANCE OF KICKBACK
• Recognize ttiat kickback can happen. With a basic
understanding of kio№ack, you can reduce the element of
surprise which contributes to accidents.
• Never let the moving chain contact any object at the flp
of the guide bar. Figure 2.
• Keep ^ woiidng area free from obstructions such as
other trees, branches, roci<s, fences, stumps, etc. Figures.
Eiitninate or avoid any obstruction that your chain could hit
v/htie you are cutting through a particular log or branch.
• Keep your chain sharp and property tensioned. A loose
or dull chain can increase the chance of kic^cback to occur.
Follow TOnufacturer’s chain sharpening and mantenance
instructions. Check tension at regular intervals with the
engine slopped, never with the engine running. Make sure
the bar clamp nuts are securely tightened after tensioning
the chain.
• Begin and continue cutting at full ttirottle. If the chain is
mowng at a slower speed, there is greater chance for kfdcback to occur.
' Cut one log at a time.
' Use extreme caution when re-entering a previous cut.
’ Do not attempt plunge cuts.
' Watdi for shifting logs or other forces that could close a
cut and pinch or fall into chain.
Use the Reduced-Kickback Guide Bar and LowKtckbadc Chain speeded for your saw.

MAINTAIN CONTROL
• Keep a good, finn grip on the saw with both hands
when the engine is running and don’t let go. Rgure 4.
A firm grip can neutralize kickback and he^ you maintain
control of the saw. Keep the fingers of your left hand encirding and your left thumb under the front handlebar. Keep
your right hand comptetety around the rear handle whether
you are right handed or left handed. Ifeep >our left arm
straight vrith the elbow locked.
• Position your left hand on the front handlebar so it is
in a sbaight line with your right hand on the rear han
dle when mafdng bucMng cuts. Figure 4. Never reverse
right and left hand positions for any tjpe of cutting.
• Stand with your weight evenly taianced on both feet
• Stand slightly to the left side of toe saw to keep your
body from being in a direct line vnth toe cutting chain.
Figure 4.
• Do not overreach. You could be drawn or thrown off bal
ance and tose control of the saw.
• Do not cut above shoulder he^ht It is difflojft to main
tain control of saw above shoulder height
UNDERSTANDING REACTIVE FORCES
Pindi-Kickback and Pull-In occur when tire chain is sud-
derdy stopped by being pinched, caught, or by contact
ing a foreign object in the wood. This 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 tiie chain
rotation. Either reaction can resuit in toss of control and pos
sible serious injury.
• PindvKickbadc
- occurs when chain on lop of guide bar is suddenly
stopped.
- rap/y/y drives saw straight bad< toward operator.
• PulHn

OPERATION
BEFORE STARTING ENGINE
WARNING:
A
GUIDE BAR AND CHAIN OIL
For maximum guide bar and chain life, we recommend you
use Craftsman chain saw bar oil. If Craftsman bar oil is hot
available, you may use a good grade SAE30 oil until you are
able to obtain Craftsman brand. The oil output is automati
cally metered during operation. Your saw wifi use approxF
rnately one tank of bar oil for every tank of fuel mix. Always
fill the bar oil lank when you fill the fuel tank.
GASOLINE
The two-cycle engine on this product requires a fuel mixture
of regular unleaded gasoline and a quality 40:1
2-cycle engine oil (AIR-COOLED) for lubrication of the bear
ings and other moving parts. The correct fuel/oit mixture is
40:1 (see Fuel Mixture Chart).Too little oil or the irxxjtrect oil
ti^e will cause poor performance and may cause the engine
to overheat and seize.
Gasoline and oil must be piemixed in a clean approved fuel
container. Always use fresh regular unleaded gasoline.
This engine is certified to operate on unieaded 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 for
mation of acids during storage. Actdfc 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 starling the engine
and letting it run until it stops. Use fresh fuel next season.
BE SURE TO READ THE FUEL HANDLING
INFORMATION IN THE SAFETY RULES
SECTION ON PAGE 2 OF "mis MANUAL
BEFORE YOU BEGIN.
IF YOU DO NOT UNDERSTAND THE FUEL
HANDLING SECTION DO NOT ATTEMPT TO
FUEL YOUR UNIT; SEEK HELP FROM
SOMEONE THAT DOES UNDERSTAND THE
FUEL HANDLING SECTION OR CALL THE
CUSTOMER ASSISTANCE HOTLINE AT
1-800-235-5878.
FUEL STABIUZER
Fuel stabilizer is an acceptable alternative in minimizing the
formation of fuel gum deposits during storage. Add stabiliz
er to gasoline in fuel lank or storage container. Always fol
low the fuel mix ratio found on the staMlizer container. Run
eni^ne at least 5 minutes after adding stabilizer to allow the
stabilizer to reach the carburetor. Yju do not have to drain
the fuel tank for storage if you are using fuel stabilizer.
CRAFTSMAN 40:1 2-cycte engine oil (AIR-COOLED) is
specially blended with fuel stabilizers. It you do not use this
Sears oil, can add a fuel stabilizer to your fuel tank.
40:1 2-CYCLE AIR-COOLED ENGINE OIL
CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is
strongly recommended. This oil is specificaily blended vwth
fuel stabilizers for increased fuel stability (extends fuel life
up to 5 times longer) and reduced smoke.
If CRAFTSMAN 40.T 2-cyde engine oil (AIR-COOLED) is
not available, use a good quality 2-cyc!e engine oil (AIR
COOLED) that has a recommended fuel mix ratio of 40:1.
IMPORTANT! 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 unit’s fuel tank.
