SAFETY RULES
S Always use approved hearing protection.
Regular users should have hearing
checked regularly as chain saw noise can
damage hearing. Long--term exposure to
noise can result in permanent hearing im-
pairment.
WARNING: Always disconnect
spark plug wire and place wire where it can-
not contact spark plug to prevent accidental
starting when setting up, transporting, ad-
justing or making repairs except carburetor
adjustments.
Because a chain saw is a high-speed wood-
cutting tool, special safety precautions must
be observed to reduce the risk of accidents.
Careless or improper use of this tool can
cause serious injury.
S Keep all parts of your body away from the
chain when the engine is running.
S Keep children, bystanders, and animals a
minimum of 10 Meters away from the work
area. Do not allow other people or animals
to be near the chain saw when starting or
operating the chain saw.
S Do not handle or operate a chain saw when
you are fatigued, ill, or upset, or if you have
taken alcohol, drugs, or medication. You
must be in good physical condition and men-
tally alert. Chain saw work is strenuous. If
you have any condition that might be aggra-
vated by strenuous work, check with your
doctor before operating a chain saw.
PLAN AHEAD
S Read this manual carefully until you com-
pletely understand and can follow all safety
rules, precautions, and operating instruc-
tions before attempting to use the unit.
S Restrict the use of your saw to adult users
who understand and can follow safety
rules, precautions, and operating instruc-
tions found in this manual.

with defective safety equipment. Safety
equipment must be inspected and main-
tained. If your chain saw does not pass in-
spection, take the saw to your nearest ser-
vice dealer for repair.
S Chain brake. Brush off any wood dust, res-
in and dirt from the chain brake and clutch
drum. Dirt and wear can impair operation of
the brake. For additional information, see
OPERATING YOUR UNIT section.
S Throttle trigger lock -out. Check that the
throttle trigger can not beoperated until the
throttle lock--out is pressed.
S Chain catcher. Check that the chain
catcher is not damaged and is firmly at-
tached to the body of the chain saw.

CHAIN SAW SAFETY EQUIPMENT
NOTE: In this section, the safety features of
the chain saw and their function are explained.
For inspection and maintenance, see instruc-
tions in the CHECKING, MAINTAINING AND
SERVICING CHAIN SAW SAFETY EQUIP-
MENT section. See instructions under the
WHAT IS WHAT? section, to find where these
parts are located on your chain saw. The life
span of the machine can be reduced and the
risk of accidents can increase if machine main-
tenance is not carried out correctly and if ser-
vice and/or repairs are not carried out profes-
sionally. If you need further information, please
contact your nearest service dealer.
S Chain brake. Your chain saw is equipped
with a chain brake that is designed to stop
the chain from moving.
MAINTAIN YOUR SAW IN GOOD
WORKING ORDER
S 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. 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 fly-
wheel to burst.
WARNING: The chain brake is de-
signed to stop the chain immediately if you
get a kickback. The chain brake reduces the
risk of accidents, but only you can prevent
them. DO NOT ASSUMETHAT THE CHAIN
BRAKE WILL PROTECT YOU IN THE
EVENT OF A KICKBACK.
S Throttle trigger lock -out. The throttle
lock--out is designed to prevent accidental
operation of the throttle trigger.
S Chain catcher. The chain catcher is de-
signed to catch the saw chain if it breaks.
S Vibration damping system. Your chain
saw is equipped with a vibration damping
system that is designed to minimize vibra-
tion and make operation easier.
S Make certain the saw chain stops moving
when the throttle trigger is released. For
correction, refer to CARBURETOR AD-
JUSTMENTS.
S Never modify your saw in any way. Use
only attachments supplied or specifically
recommended by the manufacturer.
S Keep the handles dry, clean, and free of oil
or fuel mixture.
S Keep fuel and oil caps, screws, and fas-
teners securely tightened.
S Use only McCulloch accessories and re-
placement parts as recommended.
SAFETY NOTICE: Exposure to vibrations
through prolonged use of gasoline powered
hand tools could cause blood vessel or nerve
damage in the fingers, hands, and joints of peo-
ple prone to circulation disorders or abnormal
swellings. Prolonged use in cold weather has
been linked to blood vessel damage in other-
wise healthy people. If symptoms occur such
as numbness, pain, loss of strength, change in
skin color or texture, or loss of feeling in the fin-
gers, hands, or joints, discontinue the use of
this tool and seek medical attention. An anti-
vibration system does not guarantee the avoid-
ance of these problems. Users who operate
power tools on a continual and regular basis
must monitor closely their physical condition
and the condition of this tool.
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
the areas where fuel is mixed or poured.
There should be nosmoking, openflames,
or work that could cause sparks. Allow en-
gine to cool before refueling.
S Mix and pour fuel in an outdoor area on bare
ground; store fuel in a cool, dry, well venti-
lated place; and use an approved, marked
container for all fuel purposes. Wipe up all
fuel spills before starting saw.
S Move at least 10 feet (3 meters) from fuel-
ing site before starting engine.
S ON/STOP switch. The ON/STOP switch
should be used to stop the engine.
4
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.
Avoid obstructions
S Storetheunit and fuel in an area where fuel
vapors cannot reach sparks or open
flames from water heaters, electric motors
or switches, furnaces, etc.
Clear the
working area
REDUCE THE CHANCE OF
KICKBACK
KICKBACK
S Recognize that kickback can happen.
With a basic understanding of kickback,
you can reduce the element of surprise
which contributes to accidents.
WARNING: Avoid kickback which
can result in serious injury. Kickback is the
backward, upwardor sudden forwardmotion
of the guide bar occurring when the saw
chain near the upper tip of theguide bar con-
tacts any object such as a log or branch, or
when the wood closes in and pinches the
saw chain in the cut. Contacting a foreignob-
ject 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 up-
per 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 to-
ward 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 sudden 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 Never let themoving chain contact any ob-
ject at the tip of the guide bar.
S Keep the 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 you are cutting through a particular log
or branch.
S Keep your saw chain sharp and properly
tensioned. A loose or dull chain can increase
the chance of kickback occurring. Follow
manufacturer’s chain sharpening and main-
tenance instructions. Check tension at regu-
lar intervals with the engine stopped, never
with the engine running. Make sure the bar
clamp nuts are securely tightened after ten-
sioning the chain.
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 Cut one log at a time.
S Use extreme caution when re-entering a
previous 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 Reduced--Kickback Guide Bar and
Low--Kickback Chain specified for your saw.
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
stopping pulls the saw forward and away
from the operator and could easily cause the
operator to lose control of the saw.
MAINTAIN CONTROL
Stand to the lef
the saw
Avoid Pinch -Kickback:
S Be extremely aware of situations or obstruc-
tions 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 the saw as the bar is with-
drawn from an undercut when bucking.
Avoid Pull -In:
Never reverse
hand positions
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 Path
Elbow locked
Thumb on underside of

S Keep a good, firm grip on the saw with both
hands when the engine is running and don’t
let go. A firm grip will help you reduce kick-
back and maintain control of the saw. Keep
the fingers of your left hand encircling and
your left thumb under the front handlebar.
Keep your right hand completely around the
rear handle whether your are right handed or
left handed. Keep your left arm straight with
the elbow locked.
S Low--Kickback Chain, designed with a
contoured depth gauge and guard link
which deflect kickback force and allow
wood to gradually ride into the cutter.

S Position your left hand on the front handle-
bar so it is in a straight line with your right
hand on the rear handle when making
bucking cuts. Never reverse right and left
hand positions for any type of cutting.
S Standwith your weight evenly balancedon
both feet.
S Handguard, 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, de-
signed 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 kick-
back occurs.
S Stand slightly to the left side of the saw to
keep your body from being in a direct line
with the cutting chain.
S Do not overreach. You could be drawn or
thrown off balance and lose control of the
saw.
S Do not cut above shoulder height. It is diffi-
cult to maintain control of saw above
shoulder height.
WARNING: DO NOT RELY UPON
ANY OF THE DEVICES BUILT INTO YOUR
SAW. YOU SHOULD USE 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
recommended. Your saw has a low kickback
chain and bar as original equipment. Re-
pairs on a chain brake should be made by an
authorized servicing dealer. Takeyour unit to
the place of purchase if purchased from a
servicing dealer, or to the nearest authorized
master service dealer.
S Tip contact in some cases may cause a
lightning fast reverse REACTION, kicking
the guide bar upand back toward theoper-
ator.
S Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly
back toward the operator.
KICKBACK SAFETY FEATURES
WARNING: The following features are
included on your saw to help reduce the hazard
of kickback; however, such features will not to-
tally eliminate this dangerous reaction. As a
chain saw user, do not rely only on safety de-
vices. You must follow all safety precautions,
instructions, and maintenance in this manual to
help avoid kickback and other forces which
can result in serious injury.
S Reduced--Kickback Guide Bar, designed
with a small radius tip which reduces the size
of the kickback danger zone on the bar tip. A
Reduced--Kickback Guide Bar has been
demonstrated to significantly reduce the
number and seriousness of kickbacks.

9. Fit chain drive links into bar groove.
10. Pull guide bar forward until chain is snug
in guide bar groove. Ensure all drive
links are in the bar groove.
3. An adjusting pin and screw is used to ad-
just the tension of the chain. It is very im-
portant when assembling the bar, that the
pin located on the adjusting screw aligns
into a hole in the bar. Turning the screw will
move the adjustment pin up and down the
screw. Locate this adjustment before you
begin mounting the bar onto the saw. See
illustration below.
11. Now, install chain brake making sure the
adjusting pin is positioned in the lower
hole in the guide bar. Remember this pin
moves the bar forward and backward as
the screw is turned.
12. Install chainbrake nuts and finger tighten
only. Once the chain is tensioned, you
will need to tighten chain brake nuts.

Adjusting the tension:
Chain tension is very important. Chain
stretches during use. This is especially true
during the first few times you use your saw.
Always check chain tension each time you
use and refuel your saw. You can adjust the
chain tension by loosening the chain brake
nuts and turning the adjusting screw 1/4 of a
turn while lifting up on the bar.

OPERATING YOUR UNIT
tem of an engine while in storage. To avoid
engine problems, empty the fuel system be-
fore storage 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. Never use engine or
carburetor cleaner products in the fuel tank
or permanent damage may occur.
BEFORE STARTING ENGINE
WARNING: Be sure to read the fuel
information in the safety rules before you be-
gin. If you donot understand the safety rules,
do not attempt to fuel your unit. Contact an
authorized service dealer.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubri-
cation. Lubrication is provided by the auto-
matic oiler system when the oil tank is kept
filled. 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.
CHAIN BRAKE
Ensure chain brake is disengaged by pulling
the front hand guard back toward the front han-
dle as far as possible. The chain brake must
be disengaged before cutting with the saw.
WARNING: The chain must not
move when the engine runs at idle speed. If
the chain moves at idle speed refer to CAR-
BURETOR ADJUSTMENT within this
manual. Avoid contact with the muffler. A hot
muffler can cause serious burns.
Only use Bar and Chain Oil for bar and chain
lubrication.
Oil Cap
Fuel mix cap
To stop the engine, move the ON/STOP
switch to the STOP position.
To start the engine, hold the saw firmly on
the ground as illustrated below. Make sure
the chain is free to turn without contacting
any object.
Use only 15″--- 1 8 ″ of rope per pull.
Hold saw firmly while pulling starter rope.
FUELING ENGINE
WARNING: 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 2-cycle air-cooled
engine oil designed to be mixed at a ratio of
40:1. A 40:1 ratio is obtained by mixing 0,125
liter of oil with 5 liters of unleaded gasoline. DO
NOT USE automotive or boat oil. These oils
will cause engine damage. When mixing fuel
follow the instructions printed on the container.
Always read and follow the safety rules relating
to fuel before fueling your unit.
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.
IMPORTANT
Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads
to separation and formation of acids during
storage. Acidic gas can damage the fuelsys-
NOTE:Do not cut material with the choke/fast
idle lever at the FULL CHOKE position.

Starting could require pulling the starter rope
handle many times depending on how badly
the unit is flooded. If engine fails to start, re-
fer to the TROUBLESHOOTING TABLE.
STARTING A COLD ENGINE (or a
warm engine after running out of
fuel)
NOTE:Inthefollowing steps, when the cho-
ke/fast idle lever is pulled out to the full ex-
tent, the correct throttle setting for starting is

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
should be replaced by an authorized service
dealer if any part is worn to less than 0,02″ (0,5
mm) thick. Repairs on a chain brake should be
made by an authorized service dealer. Take
your unit to the place of purchase if purchased
from a servicing dealer, or to the nearest autho-
rized master service dealer.

made.
S Check chain tension before first use and af-
ter 1 minute of operation. See CHAIN TEN-
SION in the ASSEMBLY section.
Plan a clear retreat path
S Cut wood only. Do not cut metal, plastics,
masonry, non-wood building materials, etc.
S The bumper spike may be used as a pivot
when making a cut.
S Stop the saw if the chain strikes a foreign
object. Inspect thesaw and repair parts as
necessary.
Direction of Fall
45_
S Keep the chain out of dirt and sand. Evena
small amount of dirt will quickly dull a chain
and increase the possibility of kickback.
S Practice cutting a few small logs using the
following techniques to get the “feel” of us-
ing your saw before you begin a major
sawing operation.
FELLING LARGE TREES
(15 cm in diameter or larger)
The notch method is used to fell large trees.
A notch is cut on the side of the tree in thede-
sired direction of fall. After a felling cut is
made on the opposite side of tree, the tree
will tend to fall into the notch.
S

S
S
S
Squeeze the throttle trigger and allow the
engine to reach full speed before cutting.
Begin cutting with the saw frame
against the log.
NOTCH CUT AND FELLING THE
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 cut-
ting the bottom of the notch. See illustra-
tion. Once the notch is cut remove the
notch of wood from the tree.
Keep the engine at full speed the entire
time you are cutting.
Allow the chain to cut for you. Exert only
light downward pressure.
Release the throttle trigger as soon as
the cut is completed, allowing the en-
gine to idle. If you run the saw at full
throttle without a cutting load, unneces-
sary wear can occur.

TREE FELLING TECHNIQUES
WARNING: Do not cut near buildings
or electrical wires if you do not know the di-
rection of tree fall, at night since you will not
be able to see well, or during bad weather
such as rain, snow, or strong winds. as fall is
unpredictable.
Carefully plan your sawing operation in ad-
vance. You need a clear area all around the
tree so you can have secure footing. Check
for broken or dead branches which can fall
on you causing serious injury.
Natural conditions that can cause a tree to
fall in a particular direction 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 de-
termine the direction of tree lean.
S Weight and branches on one side.
S Surrounding trees and obstacles.
Look for decay and rot. If the trunk is rotted,
it can snap and fall toward the operator.
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. En-
gine noise can drown out a warning call.
Remove dirt, stones, loose bark, nails, staples,
Second cut
S After removing the wood from the notch,
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 be-
tween the felling cut and the notch to form a
hinge. This hinge will help prevent the tree
from falling in the wrong direction.
Hinge holds tree on stump and helps
control fall

NOTE: Before felling cut is complete, use
wedges to open the cut when necessary to
controlthedirectionof fall. To avoid kickback
or chain damage, use wood or plastic
wedges, but never steel or iron wedges.
10
S Be alert to signs that the tree is ready to fall:
cracking sounds, widening 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 re-
treat path.
WARNING: Never turn saw upside
down to undercut. The saw cannot be con-
trolled in this position.
First cut on pressure side of log
S DO NOT cut down a partially fallen tree with
your saw. Be extremely cautious with par-
tially fallen trees that may be poorly sup-
ported. 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.

CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a fallen
tree to the desired log length.
First cut on pressure side of log
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.
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 Give special attention to logs under strain
to prevent the saw from pinching. Make
the first cut on the pressure side to relieve
the stress on the log.
Important points
S Cut only one log at a time.
S Cut shattered wood very carefully; sharp
pieces of woodcould beflung towardoper-
ator.
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.
BUCKING USING A LOG OR SUP-
PORT STAND
S Remember your first cut is always on the
pressure side of the log.
S Do not cut in an area where logs, limbs,
and roots are tangled. Drag the logs into a
clear area before cutting by pulling out ex-
posed and cleared logs first.
S Your first cut should extend 1/3 of the
diameter of the log.
S Finish with your second cut.

TYPES OF CUTTING USED FOR
BUCKING
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. Restart
the saw and carefully reenter the cut. Do not
attempt torestart your saw whenit is pinched
or hung in a log.

11
S Start at base of the felled tree and work to-
ward the top, cutting branches and limbs.
Remove small limbs with one cut.
LIMBING AND PRUNING
WARNING: Be alert for and guard
against kickback. Do not allow the moving
chain to contact any other branched or objects
at the nose of the guide bar when limbing or
pruning. Allowing such contact can result in
serious injury.
S Keep the tree between you and the chain
as much as possible.
S Remove larger, supporting branches with
the cuttingtechniques described in BUCK-
ING WITHOUT A SUPPORT.
S Always use an overcut to cut small and
freely hanging limbs. Undercutting could
cause limbs to fall and pinch saw.
WARNING: Never climb into a tree to
limb or prune. Do not stand on ladders, plat-
forms, a log, or in any position which can cause
you to lose your balance or control of 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.
IMPORTANT POINTS
S Watch out for springpoles. Use extreme
caution when cutting small size limbs. Slen-
der material may catch the saw chain and be
whipped toward you or pull you off balance.
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 Make your fist cut 1/3 of the way through
the bottom of the limb.
S Next make a 2nd cut all the way through
the limb. Then cut a third overcut leaving
a1 to 2inchcollar fromthetrunk of thetree.
S Keep a clear work area. Frequently clear
branches out of the way to avoid tripping
over them.

LIMBING
S Always limb atreeafter it is cut down. Only
then can limbing be done safely and prop-
erly.
S Leave the larger limbs underneath the

BAR MAINTENANCE
CHAIN SHARPENING
If your saw cuts to one side, has to be forced
through the cut, or been run with an improper
amount of bar lubrication it may be neces-
sary to service your bar.
Chain sharpening is a complicated task that
requires special tools. We recommend that
you refer chain sharpening to a professional
chain sharpener.
A worn bar will damage your chain andmake
cutting difficult.
CARBURETOR ADJUSTMENTS
After each use, ensure ON/STOP switch is
in the STOP position, then clean all sawdust
from the guide bar and sprocket hole.
To maintain guide bar:
WARNING: The chain will be moving
during most of this procedure. Wear your pro-
tective equipment and observe all safety pre-
cautions. The chain must not move at idle
speed.
The carburetor has been carefully set at the
factory. Adjustments may be necessary if
you notice any of the following conditions:
S Chain moves at idle. See IDLE SPEED--T
adjusting procedure.
S Saw will not idle. See IDLE SPEED--T ad-
justing procedure.
S Move ON/STOP switch to the STOP posi-
tion.
S Loosen and remove chain brake nuts and
chain brake. Remove bar and chain from
saw.
S Clean the oil holes and bar groove after each
5 hours of operation.
Remove Sawdust From
Guide Bar Groove
Idle Speed---T
Allow engine to idle. If the chain moves, idle
is too fast. If the enginestalls, idle is tooslow.
Adjust speed until engine runs without chain
movement (idle too fast) or stalling (idle too
slow). The idle speed screw is located in the
area above the primer bulb and is labeled T.
S Turn idle speed screw (T) clockwise to in-
crease engine speed.
Oil Holes
S Burring of guide bar rails is a normal
process of rail wear. Remove these burrs
with a flat file.
S Turn idle speed screw (T) counterclock-
wise to decrease engine speed.
STORAGE
S When rail top is uneven, use a flat file to re-
store square edges and sides.

S The guide bar and chain must always be
covered with a scabbard when the machine
is being transported or in storage in order to
prevent accident contact with the sharp
chain. Even a non--moving chain can cause
serious cuts to yourself or persons you
bump into with an exposed chain.
Worn Groove
Correct Groove
Replace guide bar when the groove is worn,
the guide bar is bent or cracked, or when
excess heating or burring of the rails occurs.
If replacement is necessary, use only the guide
bar specified for your saw in the repair parts list
or on the decal located on the chain saw.
