GUARD AGAINST KICKBACK
Follow all safety rules to help avoid
kickback and other forces which can
result in serious injury.
Kickback Path
Avoid Obstructions
Clear The
WorkingArea
WARNING:
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 result in
loss of chain saw control.
S
RotationalKickback 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 i n stant. The
result is a lightning fast, reverse
reaction which kicks the guide bar up
and back toward the operator.
S
Pinch-Kickbackcan 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 sudden stopping of the chain results in a
reversal of the chain force used to
cut wood and causes the saw to
move i n the opposite direction of the
chain rotation. The saw is driven
straight back toward the operator.
S
Pull-Incan 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 stopping pulls the saw forward and away
from the operator and could easily
cause the operator to lose control of
the saw.
REDUCETHE CHANCEOF
KICKBACK
S
Recognize that kickback can happen.
With a basic understanding of kickback, you can reduce the element of
surprise which contributes to accidents.
S
Never let the moving chain contact
any object at the tip of the guide bar.
S
Keep working area free from obstructions such as other trees, branches,
rocks, fences, stumps, etc. Eliminate
or avoid any obstruction that your
saw chain could hit while cutting.
S
When cutting a branch, do not let the
guide bar contact another branch or
other objects around it.
S
Keep saw chain sharp and properly
tensioned. A loose or dull chain can
4
Page 5
increase the chance of kickback.
Follow manufacturer’s chain sharpening and maintenance instructions.
Check tension at regular intervals,
but never with engine running. Make
sure chain brake nuts are securely
tightened.
S
Begin and continue cutting at full
speed. If the chain is moving at a
slower speed, there is greater
chance of kickback occurring.
S
Use extremecaution when reentering a cut.
S
Do not attempt cuts starting with the
tip of the bar (plunge cuts).
S
Watch for shifting logs or other forces
that could close a cut and pinch or
fall into chain.
S
Use the specified Reduced-Kickback
Guide Bar and Low-Kickback Chain.
Avoid Pinch-Kickback:
S
Be extremely aware of situations or
obstructions that can cause material
to pinch the top of or otherwise stop
the chain.
S
Do not cut more than one log at a
time.
S
Do not twist saw as bar is withdrawn
from an undercut when bucking.
Avoid Pull-In:
S
Always begin cutting with the engine
at full speed and the saw housing
against wood.
S
Use wedges made of plastic or
wood. Never use metal to hold the
cut open.
MAINTAINCONTROL
Stand to the left of the saw
Thumb on
underside
of handlebar
Elbow
locked
Never reverse hand positions
S
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.
S
Position your left hand on the front
handlebar so it is in a straight line
with your right hand on the rear handle when making bucking cuts.
Stand slightly to the left side of the
saw to keep your body frombeing in
a direct line with the cutting chain.
S
Stand with your weight evenly balanced on both feet.
S
Do not overreach. You could be
drawn or thrown offbalance and lose
control.
S
Do not cut above shoulder height. It
is difficult to maintain control of saw
above shoulder height.
KICKBACKSAFETY FEATURES
WARNING:
The following features are included on your saw to help
reduce 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.
S
Front Hand Guard: designed to reduce the chance of your left hand
contacting the chain if your hand
slips off the front handlebar.
S
Position of 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.
S
Reduced-Kickback Guide Bar: designed with a small radius tip which
reduces the size of the kickback danger zone. This type bar has been
demonstrated to significantly reduce
the number and seriousness of kickbacks.

built into your saw.
WARNING:
Computed kickback
angle (CKA) listed on your saw and
listed in the CKA table below represents
angle of kickback your bar and chain
combinations will have when tested in
accordance with CSA (Canadian Standards Association) standards. When
purchasing replacement bar and chain,
considerations should be given to the
lower CKA values. Lower CKA values
represent safer angles to the user, higher values indicate more angle and higher kick energies. Computed angle represented indicates total energy and angle
associated without activation of the
chain brake during kickback. In all cases
lower CKA values represent a safer operating environment for the user.
The following guide bar and chain combinations meet kickback requirements
of CSA Z62.1 and Z62.3when used on
saws listed in this manual. Use of bar
and chain combinations other than
those listed is not recommended and

BEFORE STARTINGENGINE
WARNING:
Be sure to read the
fuel handling information in the safety
rules section of this manual before you
begin. Ifyou do not understand the
fuel handling information do not attempt to fuel your unit. Seek help from
someone that does understand the information or contact your Sears Service Centre.
GUIDE BAR AND CHAIN OIL
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 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 Craftsmanbar oil
is not available, you may use a good
grade SAE 30 oil until you are able to
obtain Craftsmanbrand. The oil output
is automatically meteredduring 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 ENGINE
WARNING:
Remove fuel cap
slowly when refueling.
This engine is certified to operate on unleaded gasoline. Before operation, gaso-
line 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. A 40:1 ratio is obtained by mixing 3.2 ounces (95 ml) of oil with 1 gallon (4 litres) of unleaded gasoline. Included with this saw is a 3.2 ounce (95
ml) container of Craftsman brand oil.
Pour the entire contents of this container
into 1 gallon (4 litres)of gasoline to
achieve the proper fuel mixture.
USE
automotive oil or marine oil. These
DO NOT
oils will cause engine damage. When
mixing fuel follow the instructions printed
on the 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 fuels (called gasohol or using
ethanol or methanol) can attractmoisture 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 for30 days or longer. Drain the
gas tank, start the engine and let it run
until the fuel lines and carburetor are
empty. Use fresh fuel next season.
See
STORAGE
instructions for addition-
al information.

CHAIN BRAKE
WARNING:
If the brake band is
worn too thin it may break when the chain
brake is triggered. With a broken brake
band, the chain brake will not stop the
chain. The chain brake must be replaced
if any part is worn to less than 0.020 inch
(0.5 mm) thick. Repairs on a chain brake
should be made by your Sears Service
Centre.Takeyour unit to the place of purchase or to the nearest Sears Service
Centre.
S
This saw is equipped with a chain
brake. The brake is designed to stop
the chain if kickback occurs.
S
The inertia--activated chain brake is activated if the front hand guard is pushed
forward, either manually (by hand) or
automatically (by sudden movement).
S
If the brake is already activated, it is disengaged by pulling thefronthandguard
back toward the front handle as far as
possible.
S
When cutting with the saw, the chain
brake must be disengaged.

WARNING:
When performing the
following procedure, the engine must
be turned off.
Hold the chain saw approximately 14”
(35 cm) above a stump or other wooden surface. Release your grip on the
front handle and use the w eight of the
saw to let the tip of the guide bar fall
forward and contact the stump. When
the tip of the bar hits the stump, the
brake should activate.
OPERATINGTIPS
S
Check chain tension before first use
and after 1 minute of operation. See
CHAIN TENSION
MAINTENANCE
in the
section.
S
Cut wood only. Do not cut metal,
plastics, masonry, non-wood building
materials, etc.
S
Stop the saw if the chain strikes a
foreign object. Inspect the saw and
repair parts as necessary.
S
Keep the chain out of dirt and sand.
Even a small amount of dirt will
quickly dull a chain and increase the
possibility of kickback.
S
Practice cutting a few small logs using thefollowing steps.This will help
you get the “feel” of using your saw
before you begin a major sawing operation.
S
Squeeze the throttle trigger and allow the engine to reach full speed
before cutting.
S
Begin cutting with the saw frame
against the log.
S
Keep the engine at full speed the
entire time you are cutting.
S
Allow the chain to cut for you. Exert
only light downward pressure.
S
Release the throttle trigger as soon
as the cut is completed, allowing
the engine to idle. If you run the
saw at full throttle without a cutting
load, unnecessary wearcan occur.
S
To avoid losing control when cut is
complete, do not put pressure on
saw at end of cut.
S
Stop engine before setting saw down.
TREE FELLING TECHNIQUES
WARNING:
Check for broken or
dead branches which can fall while
cutting causing serious injury.Do not
cut near buildings or electrical wires if
you do not know the direction of tree
fall, nor cut at night since you will not
be able to see well, nor during bad
weather such as rain, snow,or strong
winds, etc.
S
Carefully plan your sawing operation
in advance.
S
Clear the work area. You need a
clear area all around the tree so you
can have secure footing.
10
Page 11
S
The 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.
S
Study the natural conditions that can
cause the tree to fall in a particular
direction. These conditions i nclude:
S
The wind direction and speed.
S
The lean of the tree. The lean of a
tree might not be apparentdue to
uneven or sloping terrain. Use a
plumb or level to determine the direction of tree lean.
S
Weight and branches on one side.
S
Surrounding trees and obstacles.
S
Look for decay and rot. If the trunk is
rotted, it can snap and fall toward the
operator.
S
Make sure there is enough room for
the tree to fall. Maintain a distance of
2-1/2
tree lengths from the nearest
person or other objects. Engine
noise can drown out a warning call.
S
Remove dirt,stones, loose bark,
nails, staples, and w ire from the tree
where cuts are to be made.

FELLING LARGE TREES
(6 inches in diameter or larger)
The notch method is used to fell large
trees. A notch is cut on the side of the
tree in the desired direction of fall. After
a felling cut is made on the opposite
side of tree, the tree will tend tofall in
the direction of the notch.
NOTE: If treehas large buttress roots,
remove them before making the notch.
If using saw to remove buttress roots,
keep saw chain from contacting
ground to prevent dulling of the chain.
NOTCH CUT AND FELLING TREE
S
Make notch cut by cutting the top of
the notch first. Cut through
1/3
of the
diameter of the tree. Next complete
the notch by cutting the bottom. See
illustration. Once the notch is cut, remove the wedge of wood from tree.

Afterremoving the wood, make the
Felling cut here
Hinge
felling cut on the opposite side of the
notch. This is done by making a cut
about two inches higher than the
centerof the notch. This will leave
enough uncut wood between the felling cut and the notch to form a hinge.
This hinge will help prevent the tree
fromfalling in thewrong direction.
Hinge holds tree on
stump and helps
control fall

felling cut
NOTE: Before felling cut is complete,
use wedges to open the cut when
necessary to control the direction of
fall. To avoid kickback and chain
damage, use wood or plastic wedges,
but never steel or iron wedges.
S
Be alert to signs that the tree is
ready to fall: cracking sounds, widening ofthe felling cut, or movement in
the upper branches.
S
As tree starts to fall, stop saw,put it
down, and get away quickly on your
planned retreatpath.
DO NOT
S
use your saw to cut down a
partially fallen tree.Be extremely
cautious with partially fallen trees
that may be poorly supported. When
a tree doesn’t fall completely,set the
saw aside and pull down the tree
with a cable winch, block and tackle,
or tractor.
CUTTINGA FALLENTREE
(BUCKING)
Bucking is the term used for cutting a
fallen tree to the desired log size.
WARNING:
Do not stand on the
log being cut. Any portion can roll
causing loss of footing and control. Do
not stand downhill of the log being cut.
11
Page 12
IMPORTANTPOINTS
t
S
Cut only one log at a time.
S
Cut shattered wood very carefully;
sharp pieces of wood could be flung
toward operator.
S
Use a sawhorse to cut small logs.
Never allow another person to hold
the log while cutting and never hold
the log with your leg or foot.
S
Do not cut in an area where logs,
limbs, and roots are tangled. Drag logs
into a clear area before cutting them.
BUCKINGTECHNIQUES
WARNING:
If saw becomes
pinched or hung in a log, don’t tryto
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 saw and carefully reenter the cut.
Do not use a metal wedge. Do not attempt to restart your saw when it is
pinched or hung in a log.
Use a wedge to remove pinchedsaw
Turnsaw OFF and use a plastic or
wooden wedge to force cut open.
Overcutting begins on the top side of
the log with the bottom of the saw
against the log. When overcutting use
light downward pressure.

Undercuttinginvolves cutting on the
underside of the log with top of saw
against the log. When undercutting
use light upward pressure. Hold saw
firmly and maintain control. The saw
will tend to push back toward you.
WARNING:
Never turn saw upside down to undercut. The saw cannot be controlled in this position.
Always make your first cut on the
compression side of the log. The compression side of the log is where the
pressure of the log’s weight is concentrated.

LIMBINGAND PRUNING
WARNING:
Be alert forand
guard against kickback. Do not allow
the moving chain to contact any other
branches or objects at the nose of the
guide bar when limbing or pruning. Allowing such contact can result in serious injury.
WARNING:
Never climb into a
tree to limb or prune. Do not stand on
ladders, platforms, a log, or in any position which can cause you to lose
your balance or control of the saw.
IMPORTANTPOINTS
S
Watch out for springpoles.
Springpoles are small size limbs
which can whip towardyou, or pull
you offbalance. Use extreme caution when cutting small size limbs.
S
Be alert forspringback. Watch out for
branches that are bent or under
pressure. Avoid being struck by the
branch or the saw when the tension
in the wood fibers is released.
S
Frequently clear branches out of the
way to avoid tripping over them.
LIMBING
S
Limb a tree only after it is cut down.
S
Leave the larger limbs underneath
the felled tree to support the tree as
you work.
S
Startat the base of the felled tree
and work toward the top, cutting
branches and limbs. Remove small
limbs withone cut.
S
Keep the tree between you and the
chain.
S
Remove larger,supporting branches
with the cutting techniques described
BUCKING WITHOUT A SUPPORT.
in
S
Always use an overcut to cut small
and freely hanging limbs. Undercutting could cause limbs to fall and
pinch the saw.
PRUNING
WARNING:
Limit pruning to limbs
shoulder height or below. Do not cut if
branches are higher than your shoulder.Get a professional to do the job.
S
Make your first cut
1/3
of the way
through the bottom of the limb. This
cut will make the limb sag so that it
falls easily on the second cut.
S
Next make a second cut an overcut
all the way through the limb.
S
Finish the pruning operation by using
an overcut so that the stump of the
limb protrudes 1 to 2 inches from the
trunk of the tree.
