physical condition and mentally alert.
If you have any condition that might be
aggravated by strenuous work, check
with doctor before operating.
* Do not start cutting until you have a
clear work area, secure footing, and,
if you are felling trees, a planned re-
treat path.
OPERATE YOUR SAW SAFELY
es Do not operate a chain saw with one
hand. Serious injury to the operator,
helpers, bystanders or any combina-
tion of these persons may result from
one-handed operation. A chain saw
is intended for two-handed use.
Operate the chain saw only in a well-
ventilated outdoor area.
Do not operate saw from a ladder or
in a tree.
Make sure the chain will not make
contact with any object while starting
the engine. Never try to start the saw
when the quide bar is in a cut.
Do not put pressure on the saw at
the end of the cut. Applying pressure
can cause you to lose control when
the cutis completed.
Stop engine before setting saw down.
Hand carry saw only when engine is
stopped. Carry with muffler away
from body; guide bar and chain proj-
ecting behind you; guide bar covered
with a scabbard.
* Do not operate a chain saw thatis
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
& WARNING: 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 ciean 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 fo determine that it
will operate properly and perform its
intended function. Check for alignment
of moving pars, binding of moving
parts, breakage of paris, mounting and
any other conditions that may affect its
operation. A guard or other part that is
damaged should be propertly repaired
or replaced by a Sears Service Center
unless otherwise indicated elsewhere
in the operators 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.
» Always have fire extinguishing tools
available if you should need them.
Mix and pour fuel in an outdoor area
and use an approved, marked con-
tainer for all fuel purposes. Wipe up
all fuel spilis 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, efc.
GUARD AGAINST KICKBACK
Follow all safety rules to help avoid
kickback and other forces which can
result in serious injury.
Kickback Path
Clear The
Working Area
& 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 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
resultis 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 ofthe chain resulis 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.
Pulldn 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 ata
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 ata
time.
* Do not twist the saw as the baris
withdrawn from an undercut when
bucking.
Avoid Puli-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
of handlebar |
Never reverse hand positions
« À 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.
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.
Never reverse right and left hand
positions for any type of cutting.
Stand with your weight evenly bal-
anced on both feet.
Do not overreach. You could be
drawn or thrown off balance and lose
control of the saw.
Do not cut above shoulder height. |
is difficult to maintain control of saw
above shoulder height.
KICKBACK SAFETY FEATURES
A WARNING: 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. Foliow 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-
dies 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,
designed with a small radius tip which
reduces the size of the kickback dan-
ger zone on the bar tip. This type of
bar has been demonstrated to signifi-
cantly reduce the number and serious-
ness of kickbacks when tested in
accordance with ANSI B175.1.

ÁA WARNING: WE DO NOT REP-
RESENT AND YOU SHOULD NOT AS-
SUME THAT THE CHAIN BRAKE WILL
PROTECT YOU IN THE EVENT OF A
KICKBACK. Kickback is a lightning fast
action which throws the bar and rotat-
ing chain back and up toward the op-
erator. Kickback can be caused by al-
lowing 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 ofthese 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 SHOULD USE THE SAW
PROPERLY AND CAREFULLY TO AVOID
KICKBACK. Reduced-kickback guide
bars and low-kickback saw chains re-
duce the chance and magnitude of
kickback and are recommended. Your
saw has a low kickback chain and bar
as original equipment. Repairs ona
chain brake should be made by an au-
thorized Sears Service Center. Take
your unit to the place of purchase if
purchased from a servicing dealer, or
to your nearest Sears Service Center.
* Tip contact in some cases may cause
a lightning fast reverse REACTION,
kicking guide bar up and back toward
operator.
e 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 contral of the saw which
could result in serious injury. Do not
rely exclusively upon devices built into
your saw.
This unit is equipped with an anti-
vibration system and is intended for
occasional use only.
SAFETY NOTICE: Exposure to vibra-
tions through prolonged use of gasoline
powered hand tools could cause blood
vessel or nerve damage in the fingers,
hands, and joints of people prone to

in serious injury to the operator and/or
damage the chain making it unusable,
BEFORE STARTING ENGINE
A 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.
& 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
fil the fuel tank (Capacity =6.8 fl. 0z.).
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 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
ÁA WARNING: Remove fuel cap
siowly when refueling.
This engine is certified to operate on
unieaded 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 at a ratio of 40:1. A 40:1 ratio is ob-
tained by mixing 3.2 fluid cunces of oil
with 1 gallon of unleaded gasoline. In-
cluded with this saw is a 3.2 ounce con-
tainer of oil. Pour the entire contents of
this container into 1 galion 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 fo the gasoline, shake
container momentarily to assure that
the fuel is thoroughly mixed. Always
read and follow the safety rules relat-
ing to fuel before fueling your unit.
CAUTION: Never use straight gasoline
in your unit. This will cause permanent
engine damage and void the limited
warranty.
FUEL REQUIREMENTS
This engine requires the use of
minimum 87 octane [R+M]/2 clean
gasoline.
IMPORTANT
Use of alcohol blended fuels (called
gaschol or using ethanol or methanol)
can cause major engine performance
and durability problems.
A WARNING: Altemative fuels (not
gasoline) such as E-15 (15% alcohol),
Е-20 (20% alcohol), E-85 (85% alcohol)
are NOT classified as gasoline and are
NOT approved for use in 2-stroke gaso-
line engines. Use of altemative fuels will
cause problems such as: improper
cluten engagements, overheating, vapor
lock, power loss, lubrication deficiency,
deterioration of fuel lines, gaskets and
internal carburetor components, etc. Al-
ternative fuels cause high moisture ab-
sorption into the fuel/oil mixture leading
to oil and fuel separation.
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.
& WARNING: 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
e 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.

disengaged by pulling the front hand
guard back toward the front handle
as far as possible.
* When cutting with the saw, the chain
brake must be disengaged.
Disengaged Tu
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.
Place the saw on firm ground. Grip the
rear handle with your right hand and
the front handle with your left hand.
Apply full throttle by fully depressing
the throttle trigger. Activate the chain
brake by turning your left wrist against
the hand guard without releasing your
grip around the front handle. The chain
should stop immediately.
OPERATING TIPS
* Check chain tension before first use
and after 1 minute of operation, and
each time before you start the chain
saw. See CHAIN TENSION in the
MAINTENANCE section.
* Cut wood oniy. Do not cut metal, plas-
tics, masonry, non-wood building ma-
terials, etc.
e Stop the saw if the chain strikes a
foreign object. Inspect the saw and
repair or replace parts as necessary,
If the chain jumps off the guide bar,
inspect the chain for damaged drive
links before reinstalling. Burrs on
drive links, which prevent them from
entering the groove of the guide bar,
can be removed with a flat file.
11
* Keep the chain out of dirt and sand.
Even a small amount of dirt will dull a
chain, increase the possibility of kick-
back, and require chain sharpening or
replacement.
Practice cutting a few small logs us-
ing the following techniques to get
the “feel” of using your saw before
you begin a major sawing operation.
Squeeze the throttle trigger and allow
the engine to reach full speed before
cutting.
* Begin cutting with the saw frame
against the log.
* Keep the engine at full speed the
entire time you are cutting.
« Allowthe chain to cut for you. Exert
only light downward pressure. If
you force the cut, damage to the
bar, chain, or engine can result.
* Release the throttle trigger as soon
as the cut is completed, aliowing
the engine to idle. fyourunthe saw
at full throttle without a cutting load,
unnecessary wear can occur fo the
chain, bar, and engine. To maxi-
mize operating efficiency, do not
run the engine for longer than 30
seconds at a time at full throttle.
To avoid losing control when cutis
complete, do not put pressure on
saw at end of cut.
* Stop the engine before setting the
saw down after cutting.
TREE FELLING TECHNIQUES
A WARNING: Check for broken or
dead branches which can fali while cut-
ting 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. If
the tree makes contact with any utility
line, the utility company should be noti-
fied immediately.
» Carefully plan your sawing operation
in advance.
* Clear the work area. You need a clear
area all around the free so you can
have secure fooling.
* 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.
* Study the natural conditions that can
cause the tree to fall in a particular di-
rection.
Natural conditions that can cause a tree
to fall in a particular direction include:
* The wind direction and speed.
* The lean of the tree. The lean ofa
tree might not be apparent due to un-
even or sloping terrain. Use a plumb
or level to determine the direction of
tree lean.
* Weight and branches on one side.
e Gurrounding trees and obstacles.
Look for decay and rot. If the trunk is
rotted, it can snap and fall toward the
operator. Check for broken or dead
branches which can fall on you while
cutting. Make sure there is enough
room for the free to fall. Maintain a dis-
tance of 2-1/2 free lengths from the near-
est person or other objects. Engine
noise can drown out a warning call.
Remove dirt, stones, loose bark, nails,
staples, and wire from the tree where
cuts are to be made.
Plan a clear retreat path to the rear
and diagonal to the line of fall.
Plan a clear retreat path
%. P
FELLING LARGE TREES
(6 inches (15 em) 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 into
the notch.
NOTE: If the free has 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 THE
TREE
* Make notch cut by cutting the top of
the notch first. Cut through 1/3 ofthe
diameter of the tree. Next complete
the notch by cutting the bottom of the
notch. See illustration. Once the
notch is cut remove the notch of
wood from the tree.
12
Final (felling) cut here, 2 inches
(5 cm) above center of notch.
First cut
« After removing the wood from the
notch, make the felling cut on the op-
posite side of the notch. This is done
by making a cut about two inches (5
em) higher than the center of 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 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 cutifnecessary
to control the direction of fall. To avoid
kickback and chain damage, use wood
or plastic wedges, butneversteel oriron
wedges.
* 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.
* As tree starts to fall, stop saw, put it
down, and get away quickly on your
planned retreat path.
* DO NOT cut down a partially fallen tree
with your saw. Be extremely cautious
with partially fallen trees that may be
poorly supported. When a tree doesnt
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 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.
IMPORTANT POINTS
es Cut only one log at a time.
se Cut shattered wood very carefully;
sharp pieces of wood could be flung
toward operator.
» 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.
* Do not cut in an area where logs,
limbs, and roots are tangled such as in
a blown down area. Drag the logs into
a clear area before cutting by pulling
out exposed and cleared logs first.
TYPES OF CUTTING USED FOR
BUCKING
A 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. To avoid kickback and chain
damage, 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 pinched saw
Turn saw ‚OFF and dusca 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.
Undercutting involves 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.
13
& WARNING: Never turn saw up-
side down to undercut. The saw can-
not be controlled in this position.
Always make your first cut on the com-
pression side of the log. The compres-
sion side of the log is where the pres-
sure of the log's weight is
concentrated.
First cut on compression side of log
First cut on compression side of log
BUCKING WITHOUT A SUPPORT
* Overcut through 1/3 of the diameter
of the log.
e Roi the log over and finish with a
second overcut.
* Watch for logs with a compression
side to prevent the saw from pinch-
ing. See illustrations for cutting logs
with a compression side.
BUCKING USING ALOG OR
SUPPORT STAND
* Remember your first cut is always on
the compression side of the log.
{Refer to the illustrations below for
your first and second cut)
* Your first cut should extend 1/3 of the
diameter of the log.

LIMBING AND PRUNING
ÁA 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.
Allowing such contact can result in
serious injury.
A WARNING: Never climb into a
tree to limb or prune. Do not stand on
ladders, platforms, a log, or in any posi-
tion which can cause you fo lose your
balance or control of the saw.
IMPORTANT POINTS
« Work slowly, keeping both hands firmly
gripped on the saw. Maintain secure
footing and balance.
* Watch out for springpoles. Springpoles
are small size limbs which can catch
the saw chain and whip toward you or
pull you off balance. Use extreme cau-
tion when cutting small size limbs or
slender material.
« 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.
e Keep a clear work area. Frequently
clear branches out of the way 10 avoid
tripping over them.
LIMBING
* Always limb a tree after it is cut
down. Only then can limbing be done
safely and properly.
« Leave the larger limbs underneath the
felled tree to support the tree as you
work.
» Start at the base of the felled tree and
work toward the top, cutting branches
and limbs. Remove small limbs with
one cut.

* Always use an overcut to cut small
and freely hanging limbs. Undercut-
ting could cause limbs to fall and
pinch the saw.

CHECK CHAIN TENSION
A 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 especially true
during the first few times you use your
saw. Always check chain tension each
time before you start the chain 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.

2. Loosen bar nuts until they are
finger tight against the clutch cover.
3. Turn adjusting screw clockwise
until chain solidly contacts bottom
of guide bar rail.
4. Using bar tool, roll chain around
guide bar to ensure all links are in
bar groove.
5. Lift up tip of guide bar to check for
sag. Release tip of guide bar, then
turn adjusting screw 1/4 turn clock-
wise. Repeat until sag does not
exist.
Adjusting Screw - 1/4 Turn
DS
6. While lifting tip of guide bar, tighten
bar nuts securely.
7. Use the screwdriver end of the bar
tool to move chain around guide bar.
8. If chain does not rotate, it is too
tight. Slightly loosen bar nuts and
loosen chain by turning the adjust-
ing screw 1/4 turn counterclock-
wise. Retighten bar nuts.
9. If chain is too loose, it will sag be-
low the guide bar. DO NOT operate
the saw if the chain is loose.
NOTE: The chain is tensioned correctly
when the weight of the chain does not
cause it fo sag below the guide bar
(with the chain saw silting in an upright
position), but the chain still moves freely
around the guide bar.
A WARNING: Ifthe saw is operated
with a loose chain, the chain could jump
off the guide bar and result in serious
injury to the operator and/or damage the
chain making it unusable. If the chain
jumps off the guide bar, inspect each
drive link for damage. Damaged chain
must be repaired or replaced.
CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A dull
chain makes a sawdust powder and
cuts slowly. See CHAIN SHARPENING.
16
CHECK GUIDE BAR
Conditions which require guide bar
maintenance:
* Saw cuts to one side or at an angle.
* Saw has to be forced through the cut.
* inadequate supply of oil to bar/chain.
Check the condition of quide bar each
time chain is sharpened. A worn guide
bar will damage the chain and make
cutting difficult.
After each use, ensure ON/STOP
switch is in the STOP position, then
ciean ali sawdust from the guide bar
and sprocket hole.
To maintain guide bar:
* Move ON/STOP switch to STOP,
* Loosen and remove bar nuts and
clutch cover. Remove bar and chain
from saw,
* Ciean the oil holes and bar groove
after each 5 hours of operation.
* Burring of guide bar rails is a normal
process of rail wear. Remove these
burrs with a flat file.
* When rail top is uneven, use a flat file
to restore square edges and sides.
« File Rail Edges ——

serious injury.
A WARNING: Wear protective
gloves when handling chain. The chain
is sharp and can cut you even when it is
not moving.
Conditions which indicate the need for
chain sharpening:
e Reduction in size of wood chips. The
size ofthe wood chip will decrease
as the chain gets duller until it be-
comes more like a powder than a
chip. Note that dead or rotted wood
will not produce a good chip.
* Saw cuts to one side or at an angle.
* Saw has to be forced through the cut.
Tools required:
e 7/32 inch (5 mm) diameter round file
and file holder
