from body; guide bar & chain project-
ing behind you; guide bar preferably
covered with a scabbard.
• Do not operate a chain saw that is
damaged, improperly adjusted, or
not completely and securely as-
sembled. Always replace bar, chain,
hand guard, or chain brake immedi-
ately if it becomes damaged, broken
or is otherwise removed.
MAINTAIN YOUR SAW IN GOOD
WORKING ORDER
,_LWARNING: Disconnect the
spark plug before performing mainte-
nance except carburetor adjustments.
• Have all chain saw service performed
by a qualified service dealer with the
exception of the items listed in the
MAINTENANCE section of this manual.
• Make certain the saw chain stops
moving when the throttle trigger is
released. For correction, refer to
CARBURETOR ADJUSTMENT.
• Keep the handles dry, clean, and
free from oil or fuel mixture.
• Keep caps and fasteners securely
tightened.
• Nonconforming replacement compo-
nents or the removal of safety devices
may cause damage to the unit and
possible injury to the operator or by-
standers. Use only Craftsman acces-
sories and replacement parts as rec-
ommended. Never modify your saw.
• Maintain chain saw with care.
• Keep unit sharp and clean for better
and safer performance.
• Follow instructions for lubricating and
changing accessories.
• Check for damaged parts. Before fur-
ther use of the chain saw, a guard or
other part that is damaged should be
carefully checked to determine that it
will operate properly and perform its
intended function. Check for alignment
of moving parts, binding of moving
parts, breakage of parts, mounting and
any other conditions that may affect its
operation. A guard or other part that is
damaged should be properly repaired
or replaced by a Sears Service Center
unless otherwise indicated elsewhere
in the operator's manual.
• When not in use, chain saws should
be stored in a dry, high or locked-up
place out of the reach of 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.
• Eliminate all sources of sparks or
flame in the areas where fuel is
mixed or poured.
• Mix and pour fuel in an outdoor area
and use an approved, marked con-
tainer for all fuel purposes. Wipe up
all fuel spills before starting saw.
• Move at least 10 feet (3 meters) from
fueling site before starting engine.
• Turn the engine off and let saw cool
in a non-combustible area, not on
dry leaves, straw, paper, etc. Slowly
remove fuel cap and refuel unit.
• Empty the fuel tank before storing or
transporting the unit. Use up fuel left in
the carburetor by starting the engine
and letting it run until it stops.
• Store the unit and fuel in an area
where fuel vapors cannot reach
sparks or open flames from water
heaters, electric motors or switches,
furnaces, etc.
GUARD AGAINST KICKBACK
Follow all safety rules to help avoid
kickback and other forces which can
result in serious injury.
_'_\ j_; Kickback Path
.
,_kWARNING: Avoid kickback
which can result in serious injury.
Kickback is the backward, upward or
sudden forward motion of the guide
bar occurring when the saw chain near
the upper tip of the guide bar contacts
any object such as a log or branch, or
when the wood closes in and pinches
the saw chain in the cut. Contacting a
foreign object in the wood can also re-
sult in loss of chain saw control.
• 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.
• Pinch-Kickback can occur when the
the wood closes in and pinches the
moving saw chain in the cut along
the top of the guide bar and the saw
chain is suddenly stopped. This sud-
den 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. The saw is driven
straight back toward the operator.
• Pull-In can occur when the moving
chain contacts a foreign object in the
wood in the cut along the bottom of
the guide bar and the saw chain is
suddenly stopped. This sudden stop-
ping pulls the saw forward and away
from the operator and could easily
cause the operator to lose control of
the saw.
REDUCE THE CHANCE OF
KICKBACK
• Recognize that kickback can hap-
pen. With a basic understanding of
kickback, you can reduce the ele-
ment of surprise which contributes to
accidents.
• Never let the moving chain contact
any object at the tip of the guide bar.
• Keep the working area free from ob-
structions such as other trees,
branches, rocks, fences, stumps,
etc. Eliminate or avoid any
obstruction that your saw chain could
hit while you are cutting.
• When cutting a branch, do not let the
guide bar contact branch or other ob-
jects around it.
• Keep saw chain sharp and properly
tensioned. A loose or dull chain can
increase the chance of kickback. Fol-
low manufacturer's chain sharpening
and maintenance instructions. Check
tension at regular intervals, but never
with the engine running. Make sure
the bar nuts are securely tightened.
• Begin and continue cutting at full
speed. If the chain is moving at a
slower speed, there is greater
chance of kickback occurring.
• Use extreme caution when re-enter-
ing a previous cut.
• Do not attempt cuts starting with the
tip of the bar (plunge cuts).
• Watch for shifting logs or other forces
that could close a cut and pinch or
fall into chain.
• Use the Reduced-Kickback Guide
Bar and Low-Kickback Chain speci-
fied for your saw.
Avoid Pinch-Kickback:
• Be extremely 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 undercut when
bucking.
Avoid Pull-In:
• Always begin cutting with the engine
at full speed and the saw housing
against wood.
• Use wedges made of plastic or wood.
Never use metal to hold the cut open.
MAINTAIN CONTROL
Stand to the left of the saw
Thumb on
underside t
of h_ \
Never reverse hand positions
• A good, firm grip on the saw with both
hands will help you maintain control.
Don't let go. Grip the rear handle with
your right hand whether you are right
or left handed. Wrap the fingers of
your left hand over and around the
front handlebar, and your left thumb
under the front handlebar. Keep your
left arm straight with the elbow locked.

KICKBACKSAFETYFEATURES
_IkWARNING: The following fea-
tures are included on your saw to help
reduce the hazard of kickback; however,
such features will not totally eliminate
this danger. Do not rely only on safety
devices. Follow all safety rules to help
avoid kickback and other forces which
can result in serious injury.
• Front Hand Guard, designed to reduce
the chance of your left hand contact-
ing the chain if your hand slips off the
front handlebar.
• Position of front and rear handlebars,
designed with distance between han-
dles 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 resis-
tance in controlling the pivot of the
saw back toward the operator if kick-
back occurs.
• Reduced-Kickback Guide Bar, de-
signed with a small radius tip which
reduces the size of the kickback
danger zone on the bar tip. This type
of bar has been demonstrated to sig-
nificantly reduce the number and se-
riousness of kickbacks when tested
in accordance with ANSI B175.1.

CHAIN BRAKE
• Chain Brake, designed to stop the
chain in the event of kickback.
_ILWARNING: WE DO NOT REP-
RESENT AND YOU SHOULD NOT AS-
SUME THAT THE CHAIN BRAKE WILL
PROTECT YOU INTHE EVENTOF A KICK-
BACK. Kickback is a lightning fast action
which throws the bar and rotating chain
back and up toward the operator. Kick-
back can be caused by allowing contact
of the bar tip in the danger zone with
any hard object. Kickback can also be
caused by pinching the saw chain along
the top of the guide bar. This action may
push the guide bar rapidly back toward
the operator. Either of these events may
cause you to lose control of the saw
which could result in serious injury or
even death. DO NOT RELY UPON ANY OF
THE DEVICES BUILT INTO YOUR SAW.
YOU SHOULDUSE THE SAW PROPERLY
AND CAREFULLY TO AVOID KICKBACK.
Reduced-kickback guide bars and low-
kickback saw chains reduce the chance
and magnitude of kickback and are rec-
ommended. Your saw has a low kick-
back chain and bar as original equip-
ment. Repairs on a chain brake should
be made by an authorized Sears Ser-
vice Center. Take your unit to the place
of purchase if purchased from a servic-
ing dealer, or to your nearest Sears Ser-
vice Center
• Tip contact in some cases may cause
a lightning fast reverse REACTION,
kicking guide bar up and back toward
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 injury. Do not
rely exclusively upon devices built into
your saw.

to stop the chain if kickback occurs. The
chain brake activates automatically in
the event of kickback. The chain brake
activates manually if the front hand
guard is pushed forward. The chain
brake is disengaged by pulling the front
hand guard back toward the front handle
as far as possible.
CHAIN TENSION
It is normal for a new chain to stretch
during the first 15 minutes of operation.
You should check your chain tension
each time before you start the chain
saw. See CHAIN TENSION under the
MAINTENANCE section.
,_WARNING: Ifthe saw is oper-
ated with a loose chain, the chain

BEFORESTARTINGENGINE
_LWARNING: Muffler is very hot
during and after use. Do not touch the
muffler or allow combustible material
such as dry grass or fuel to do so.
_,WARNING: Be sure to read the
fuel handling information in the safety
rules section of this manual before you
begin. If you do not understand the
fuel handling information do not at-
tempt to fuel your unit. Seek help from
someone that does understand the in-
formation or call the customer assis-
tance help line at 1-800-235-5878.
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 overheat-
ing shown by smoke coming from the
chain and/or 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 Craftsman brand. The oil output
is automatically metered during opera-
tion. 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 ENGINE
_LWARNING: 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 en-
gine oil. We recommend Craftsman
brand synthetic oil. Mix gasoline and
oil ata ratio of 40:1. A40:1 ratio is ob-
tained 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 con-
tainer into 1 gallon of gasoline to
achieve the proper fuel mixture.
DO NOT USE automotive or boat oil.
These oils will cause engine damage.
When mixing fuel follow the instruc-
tions printed on the oil container.
Once oil is added to the gasoline,
shake container momentarily to assure
that the fuel is thoroughly mixed. Al-
ways read and follow the safety rules
relating to fuel before fueling your unit.
IMPORTANT
Experience indicates that alcohol-
blended fuels (called gasohol or using
ethanol or methanol) can attract mois-
ture which leads to separation 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, start the en-
gine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel
next season. Never use engine or car-
buretor cleaner products in the fuel tank
or permanent damage may occur.
See the STORAGE section for additional
information
CHAIN BRAKE
Ensure 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.
_LWARNING: The chain must not
move when the engine runs at idle
speed. If the chain moves at idle
speed refer to CARBURETOR ADJUST-
MENT within this manual. Avoid contact
with the muffler. A hot muffler can
cause serious burns.
STOPPING YOUR ENGINE
• Release the throttle trigger.
• Move ON/STOP switch to the STOP
position.
STARTING POSITION
• To start the engine, hold the saw
firmly on the ground as illustrated.
Make sure the chain is free to turn
without contacting any object.
