SAFETY RULES
S Do not start cutting until you have a
WARNING: Always disconnect
spark plug wire when making repairs ex-
cept for carburetor adjustments. Be-
cause a chain saw is a high-speed
woodcutting tool, special safety precau-
tions must be observed to reduce risk of
accidents. Careless or improper use of
this tool can cause serious injury.
clear work area, secure footing, and
especially if you are felling a tree, a
retreat path.
OPERATE YOUR SAW SAFELY
S Do not operate with one hand. Seri-
ous injury to the operator, helpers, or
bystanders may result from one-
handed operation. A chain saw is in-
tended for two-handed use.
PLAN AHEAD
S Restrict the use of your saw to adult
users who understand and can fol-
low the safety rules, precautions,
and operating instructions found in
this manual.
S Wear protective gear. Always use
steel-toed safety footwear with non-
slip soles; snug-fitting clothing;
heavy-duty, non-slip gloves; eye pro-
tection such as non-fogging, vented
goggles or face screen; an approved
safety hard hat; and sound barriers
(ear plugs or mufflers) to protect your
hearing. Regular users should have
hearing checked regularly as chain
saw noise can damage hearing.
S Operate the chain saw only in a well-
ventilated outdoor area.
S Do not operate saw from a ladder or
in a tree.
S Make sure the chain will not make
contact with any object while starting
the engine. Never try to start the saw
when the guide bar is in a cut.
S Do not put pressure on the saw, es-
pecially at the end of the cut. Doing
so can cause you to lose control
when the cut is completed.
S Stop engine before setting saw down.
S Hand carry saw only when engine is
stopped. Carry with muffler away
from body; guide bar & chain project-
ing behind you; guide bar preferably
covered with a scabbard.
S Do not operate a chain saw that is
damaged, improperly adjusted, or not
completely and securely assembled.
Always replace bar, chain, hand
guard, chain brake, or other parts im-
mediately if they become damaged,
broken, or are otherwise removed.

MAINTAIN YOUR SAW IN GOOD
WORKING ORDER
S Have all chain saw service per-
formed by a qualified service dealer
except the items listed in the MAINTE-
NANCE section of this manual.
S Make certain the saw chain stops
moving when the throttle trigger is
released. For correction, refer to
CARBURETOR ADJUSTMENTS.
S Keep the handles dry, clean, and
free from oil or fuel mixture.
S Secure hair above shoulder length.
Do not wear loose clothing or jewelry;
they can get caught in moving parts.
S Keep all parts of your body away
from the chain when the engine is
running.
S Keep children, bystanders, and ani-
mals at least 30 feet (10 meters)
away from the work area when start-
ing and using the saw.
S Do not handle or operate a chain
saw when you are fatigued, ill, or up-
set, or if you have taken alcohol,
drugs, or medication. You must be in
good physical condition and mentally
alert. If you have any condition that
might be aggravated by strenuous
work, check with doctor before oper-
ating.
S Keep caps and fasteners securely
tightened.
S 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.
S Maintain chain saw with care.

WARNING: Avoid kickback which
can result in serious injury. Kickback
is the backward, upward or sudden for-
ward 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 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.
S 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.
S 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.
S Follow instructions for lubricating and
changing accessories.
S 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 Centre
unless otherwise indicated elsewhere
in the instruction manual.
S When not in use, chain saws should
be stored in a dry, high or locked-up
place out of the reach of children.
S When storing saw, use a scabbard or
carrying case.
HANDLE FUEL WITH CAUTION
S Do not smoke while handling fuel or
while operating the saw.
S Eliminate all sources of sparks or
flame in areas where fuel is mixed or
poured.
S 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.
S Move at least 10 feet (3 meters) from
fueling site before starting.
S 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.
S Store the unit and fuel in a cool, dry
well ventilated space where fuel va-
pors 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.
REDUCE THE CHANCE OF
KICKBACK
S Recognize that kickback can happen.
With a basic understanding of kick-
back, you can reduce the element of
surprise which contributes to acci-
dents.
S Never let the moving chain contact
any object at the tip of the guide bar.
S Keep working area free from obstruc-
tions 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.

increase the chance of kickback.
Follow manufacturer’s chain sharp-
ening 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 extreme caution when reenter-
ing a cut.
S Position your left hand on the front
handlebar so it is in a straight line
with your right hand on the rear han-
dle when making bucking cuts.
Stand slightly to the left side of the
saw to keep your body from being in
a direct line with the cutting chain.
S Stand with your weight evenly bal-
anced on both feet.
S Do not overreach. You could be
drawn or thrown off balance and lose
control.
S Do not cut above shoulder height. It
is difficult to maintain control of saw
above shoulder height.
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.
KICKBACK SAFETY FEATURES
WARNING: The following fea-
tures 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 re-
duce 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 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.
MAINTAIN CONTROL
Stand to the left of the saw
S Reduced-Kickback Guide Bar: de-
signed with a small radius tip which
reduces the size of the kickback dan-
ger zone. This type bar has been
demonstrated to significantly reduce
the number and seriousness of kick-
backs.

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

S Tip contact in some cases may cause
a lightning fast reverse REACTION,
kicking guide bar up and back toward
operator.
S Pinching the saw chain along the top
of the guide bar may push the guide
bar rapidly back toward the operator.
S Either of these reactions may cause
you to lose control of the saw which
could result in serious injury. Do not
rely exclusively upon safety devices
built into your saw.

CHAIN BRAKE & CKA ANGLE
S Chain Brake: designed to stop the
chain in the event of kickback.
WARNING: WE DO NOT REP-
RESENT AND YOU SHOULD NOT ASSUME
THAT THE CHAIN BRAKE WILL PROTECT
YOU IN THE EVENT OF A KICKBACK. Kick-
back is a lightning fast action whichthrows
the bar and rotating chain back and up to-
ward the operator. Kickback 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 con-
trol of the sawwhich could result in serious
injury or even death. DO NOT RELY UPON
ANY OF THE SAFETY DEVICES BUILT INTO
YOUR SAW. YOU SHOULD USE THE SAW
PROPERLY AND CAREFULLY TO AVOID
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 Stan-
dards 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, high-
er values indicate more angle and high-
er kick energies. Computed angle repre-
sented indicates total energy and angle
associated without activation of the
chain brake during kickback. In all cases
lower CKA values represent a safer op-
erating environment for the user.
KICKBACK.
Reduced--kickback guide
bars and low--kickback saw chains re-
duce the chance and magnitude of kick-
back and are recommended. Your saw
has a low kickback chain and bar as origi-
nal equipment. Repairs on a chain brake
should be made by an authorized Sears
Service Centre. Take your unitto the place
of purchase or to your nearest Sears Ser-
vice Centre.
The following guide bar and chain com-
binations meet kickback requirements
of CSA Z62.1 and Z62.3 when used on
saws listed in this manual. Use of bar
and chain combinations other than
those listed is not recommended and
may not meet the CKA requirements per
standard.

ON/STOP SWITCH
CHAIN BRAKE
The ON/STOP SWITCH is used to stop
the engine.
The CHAIN BRAKE is a device de-
signed to stop the chain if kickback oc-
curs. The chain brake activates auto-
matically in the event of kickback. The
chain brake activates manually if the
front hand guard is pushed forward.
The chain brake is disengaged by pull-
ing the front hand guard back toward
the front handle as far as possible.
THROTTLE TRIGGER
The THROTTLE TRIGGER controls en-
gine speed.
THROTTLE LOCK--OUT
The THROTTLE LOCK--OUT must be
pressed before you can squeeze the
throttle trigger. This feature prevents
you from accidentally squeezing the
trigger.
CHAIN TENSION
It is normal for a new chain to stretch
during first 30 minutes of operation. You
should check your chain tension fre-
quently. See CHAIN TENSION under the
SERVICE AND ADJUSTMENTS section.
CHOKE/FAST IDLE LEVER
The choke and fast idle are set by pull-
ing the CHOKE/FAST IDLE LEVER out
fully for cold or after refueling. The
choke provides additional fuel to the
engine during cold starting.
WARNING: 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.
BEFORE STARTING ENGINE
line must be mixed with a good quality
synthetic 2-cycle air-cooled engine oil.
We recommend Craftsman brand syn-
thetic oil. Mix gasoline and oil at a ratio
of 40:1. A 40:1 ratio is obtained by mix-
ing 3.2 ounces (95 ml) of oil with 1 gal-
lon (4 litres) of unleaded gasoline. In-
cluded 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. DO NOT
USE automotive oil or marine oil. These
oils will cause engine damage. When
mixing fuel follow the instructions printed
on the container. Once oil is added to
the gasoline, shake container momen-
tarily to assure that the fuel is thoroughly
mixed. Always read and follow the safe-
ty rules relating to fuel before fueling
your unit.
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 contact your Sears Ser-
vice 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 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.
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 sys-
tem of an engine while in storage.
To avoid engine problems, the fuel
system should be emptied before stor-
age for 30 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
OPERATING TIPS
S Check chain tension before first use
and after 1 minute of operation. See
CHAIN TENSION in the MAINTENANCE
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 us-
ing the following steps. This will help
you get the “feel” of using your saw
before you begin a major sawing op-
eration.
S Squeeze the throttle trigger and al-
low 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.
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. Take your unit to the place of pur-
chase 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 ac-
tivated 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 dis-
engaged by pulling the front hand guard
back toward the front handle as far as
possible.
S When cutting with the saw, the chain
brake must be disengaged.
Disengaged
d
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 wear can occur.
S To avoid losing control when cut is
complete, do not put pressure on
saw at end of cut.
Braking function control
CAUTION: The chain brake must be
checked several times daily. The engine
must be running when performing this
procedure. This is the only instance
when the saw should be placed on the
ground with the engine running.
S Stop engine before setting saw down.
TREE FELLING TECHNIQUES
Place the saw on firm ground. Hold the
handles with both hands and apply full
throttle. Activate the chain brake by turn-
ing your left wrist against the hand guard
without releasing your grip around the
front handle. The chain should stop imme-
diately.
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.
Inertia activating function control
WARNING: When performing the
following procedure, the engine must
be turned off.
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.
Hold the chain saw approximately 14”
(35 cm) above a stump or other wood-
en surface. Release your grip on the

Felling cut here
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 include:
S The wind direction and speed.
S The lean of the tree. The lean of a
tree might not be apparent due to
uneven or sloping terrain. Use a
plumb or level to determine the di-
rection 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 wire from the tree
where cuts are to be made.
First cut
Notch
Hinge
Second cut
S After removing the wood, make the
felling cut on the opposite side of the
notch. This is done by making a cut
about two inches higher than the
center of the notch. This will leave
enough uncut wood between the fell-
ing cut and the notch to form a hinge.
This hinge will help prevent the tree
from falling in the wrong direction.

but never steel or iron wedges.
Plan a clear retreat path
Direction of Fall
45_
S Be alert to signs that the tree is
ready to fall: cracking sounds, widen-
ing of the 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 retreat path.
S DO NOT 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.
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 to fall in
the direction of the notch.
NOTE: If tree has large buttress roots,
remove them before making the notch.
If using saw to remove buttress roots,
keep saw chain from contacting

fallen tree to the desired log size.
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, re-
move the wedge of wood from tree.
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.

First cut on compression side of log
IMPORTANT POINTS
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.
BUCKING TECHNIQUES
Frst cut ocompression side of log
WARNING: If saw becomes
pinched or hung in a log, don’t try to
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. Re-
start saw and carefully reenter the cut.
Do not use a metal wedge. Do not at-
tempt to restart your saw when it is
pinched or hung in a log.
BUCKING WITHOUT A SUPPORT
S Overcut through 1/3 of the diameter
of the log.
S Roll the log over and finish with a
second overcut.
S Watch for logs with a compresion
side. See illustration for cutting logs
with a compression side.
BUCKING USING A LOG OR
SUPPORT STAND
S Remember your first cut is always on
the compression side of the log. (Re-
fer to the illustration below for your
first and second cut).
Use a wedge to remove pinched saw
S Your first cut should extend 1/3 of the
diameter of the log.
S Finish with your second cut.
Turn saw OFF and use a plastic or
wooden wedge to force cut open.
Using a log for support
Overcutting begins on the top side of
the log with the bottom of the saw
against the log. When overcutting use
light downward pressure.

Cut
S Start at the base of the felled tree
and work toward the top, cutting
branches and limbs. Remove small
limbs with one cut.
S Keep the tree between you and the
chain.
nd
2
Cut
S Remove larger, supporting branches
with the cutting techniques described
in BUCKING WITHOUT A SUPPORT.
S Always use an overcut to cut small
and freely hanging limbs. Undercut-
ting could cause limbs to fall and
pinch the saw.
LIMBING AND PRUNING
WARNING: Be alert for and
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. Al-
lowing such contact can result in seri-
ous injury.
PRUNING
WARNING: Limit pruning to limbs
shoulder height or below. Do not cut if
branches are higher than your shoul-
der. 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.
WARNING: Never climb into a
tree to limb or prune. Do not stand on
ladders, platforms, a log, or in any po-
sition which can cause you to lose
your balance or control of the saw.
IMPORTANT POINTS
S Watch out for springpoles.
S Next make a second cut an overcut
all the way through the limb.
Springpoles are small size limbs
which can whip toward you, or pull
you off balance. Use extreme cau-
tion when cutting small size limbs.
S Be alert for springback. 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.
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.

GENERAL RECOMMENDATIONS
The warranty on this unit does not cov-
er items that have been subjected to
operator abuse or negligence. To re-
ceive full value from the warranty, the
operator must maintain unit as instruct-
ed in this manual. Various adjustments
will need to be made periodically to
properly maintain your unit.
S Once a year, replace the spark plug,
air filter element, and check guide bar
and chain for wear. A new spark plug
and air filter element assures proper
air-fuel mixture and helps your engine
run better and last longer.
S Fuel Tank -- Do not use saw if fuel
tank shows signs of damage or leaks.
S Oil Tank -- Do not use saw if oil tank
shows signs of damage or leaks.

CHECK CHAIN TENSION
Contact your Sears Service Centre for
replacement of damaged or worn parts.
NOTE: It is normal for a small amount
of oil to appear under the saw after en-
gine stops. Do not confuse this with a
leaking oil tank.
S ON/STOP Switch -- Ensure ON/STOP
switch functions properly by moving
the switch to the STOP position.
Make sure engine stops; then restart
engine and continue.
WARNING: Wear protective
gloves when handling chain. The
chain is sharp and can cut you even
when it is not moving.
Chain tension is very important.
Chains stretch during use. This is es-
pecially true during the first few times
you use your saw. Always check
chain tension each time you use and
refuel your saw.

1. Use the screwdriver end of the
chain adjustment tool (bar tool) to
move chain around guide bar to
ensure kinks do not exist. The
chain should rotate freely.
WARNING: If the saw is operated
with a loose chain, the chain could
jump off the guide bar and result in se-
rious injury.
CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A
dull chain makes a sawdust powder
and cuts slowly. See CHAIN SHARP-
ENING in the SERVICE AND ADJUST-
MENTS section.
CHECK GUIDE BAR
Conditions which require guide bar
maintenance:
S Saw cuts to one side or at an angle.
S Saw has to be forced through the cut.
S Inadequate supply of oil to bar/chain.
Check the condition of guide bar each
time chain is sharpened. A worn guide
bar will damage the chain and make
cutting difficult.
