INTRODUCTION
A chainsaw is a high-speed wood-cutting tool. Special
safety precautions must be observed to reduce the
risk of accidents.
Failure to follow all safety rules and precautions can
result in serious injury.
If situations occur which are not covered in this
manual, use care and good judgment. If you need
assistance, contact your authorized service dealer or
call customer support.
PLANNING AHEAD
• Read this manual carefully until you completely
understand and can follow all safety rules,
precautions, and operating instructions before
attempting to use the unit.
• Restrict the use of your saw to adult users who
understand and can follow safety rules, precautions,
and operating instructions found in this manual.
• Wear protective gear. Always use steel-toed safety
IRRWZHDUZLWKQRQVOLSVROHVVQXJ¿WWLQJFORWKLQJ
safety chaps; heavy-duty, non-slip gloves; eye
protection such as non-fogging, vented goggles
or face screen; an approved safety hard hat; and
VRXQGEDUULHUVHDUSOXJVRUPXIÀHUVWRSURWHFW\RXU
hearing. Regular users should have hearing checked
regularly as chainsaw noise can damage hearing.
Secure hair above shoulder length.
• Keep all parts of your body away from the chain
when the engine is running.
• Keep children, bystanders, and animals a minimum
RIPHWHUVIHHWDZD\IURPWKHZRUNDUHD'R
not allow other people or animals to be near the
chainsaw when starting or operating the chainsaw.
• Do not handle or operate a chainsaw when you are
fatigued, ill, or upset, or if you have taken alcohol,
drugs, or medication. You must be in good physical
condition and mentally alert. Chainsaw work is
strenuous. If you have any condition that might be
aggravated by strenuous work, check with your
doctor before operating a chainsaw.
• Carefully plan your sawing operation in advance.
Do not start cutting until you have a clear work
area, secure footing, and, if you are felling trees, a
planned retreat path.
OPERATING YOUR SAW
• Do not operate a chainsaw with one hand. Serious
injury to the operator, helpers, bystanders or any
combination of these persons may result from
one-handed operation. A chainsaw is intended for
two-handed use.
• Operate the chainsaw 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 guide 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 cut is completed.
• Stop the engine before setting the saw down.
• Do not operate a chainsaw that is damaged,
improperly adjusted, or not completely and securely
assembled. Always replace bar, chain, hand guard,
or chain brake immediately if it becomes damaged,
broken or is otherwise removed.
• Exposure to vibrations through prolonged use of
petrol powered hand tools could cause blood vessel
RUQHUYHGDPDJHLQWKH¿QJHUVKDQGVDQGMRLQWVRI
people prone to circulation disorders or abnormal
swellings. Prolonged use in cold weather has been
linked to blood vessel damage in otherwise healthy
people. If symptoms occur such as numbness,
pain, loss of strength, change in skin color or
WH[WXUHRUORVVRIIHHOLQJLQWKH¿QJHUVKDQGVRU
joints, discontinue the use of this tool and seek
medical attention. An anti-vibration system does not
guarantee the avoidance 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.
• With the engine stopped, hand-carry the chainsaw

• Make certain the saw chain stops moving when the
throttle trigger is released. For correction, refer to the
MAINTENANCE section for carburettor adjustment.
• Never modify your saw in any way.
• Keep the handles dry, clean, and free of oil or fuel
mixture.
• Keep fuel and oil caps, screws, and fasteners
securely tightened.
• Use only genuine accessories and replacement
parts as recommended.
• Certain regions require by law that many internal
combustion engines are to be equipped with a spark
arresting screen. If you operate a chainsaw in a
locale where such regulations exist, you are legally
responsible for maintaining the operating condition
of these parts. Failure to do so is a violation of
the law. Refer to the MAINTENANCE section for
maintenance of the spark arresting screen.

UNDERSTANDING KICKBACK
a 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 chainsaw
control.
ROTATIONAL KICKBACK
Rotational kickback can occur when the moving chain
contacts an object at the upper tip of the guide bar.
This contact can cause the chain to dig into the object,
which stops the chain for an instant. The result is a
lightning fast, reverse reaction which kicks the guide
bar up and back toward the operator.
PINCH KICKBACK
Pinch kickback can occur when 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.
PULL-IN
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.
REDUCING THE CHANCE OF KICKBACK
• Recognize that kickback can happen. With a basic
understanding of kickback, you can reduce the
element 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 obstructions 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 objects around it.
• 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 maintenance instructions. Check
tension at regular intervals with the engine stopped,
never with the engine running. Make sure the bar
nuts are securely tightened after tensioning the
chain.
• Begin and continue cutting at full speed. If the chain
is moving at a slower speed, there is greater chance
of kickback occurring.
• Use wedges made of plastic or wood. Never use
metal to hold the cut open.
• Cut one log at a time.
• Use extreme caution when re-entering a previous
cut.
• Do not attempt cuts starting with the tip of the bar
SOXQJHFXWV
• Watch for shifting logs or other forces that could
close a cut and pinch or fall into chain.
• Do not twist the saw as the bar is withdrawn from an
undercut when bucking.
• Use the reduced-kickback guide bar and low-

the rear handle whether you are right handed or left
handed. 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 balanced on both feet.
• Stand slightly to the left side of the saw to keep
your body from being in a direct line with the cutting
chain.
• Do not overreach. You could be drawn or thrown off
balance and lose control of the saw.

KICKBACK SAFETY FEATURES
a WARNING! The following features are
included on your saw to help reduce the
hazard of kickback; however, such features
will not totally eliminate this danger.
As a chainsaw user, do not rely only on
safety devices. 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.
REDUCED KICKBACK GUIDE BAR
The reduced-kickback guide bar is designed with a
small radius tip which reduces the size of the kickback
danger zone on the bar tip.
LOW-KICKBACK CHAIN
A low-kickback chain is designed with a contoured
GHSWKJDXJHDQGJXDUGOLQNZKLFKGHÀHFWNLFNEDFN
force and allow wood to gradually ride into the cutter.
FRONT HAND GUARD
The front hand guard is designed to reduce the
chance of your left hand contacting the chain if your
hand slips off the front handlebar.
The distance and “in-line” position of the hands
provided by the front and rear handles work together
to give balance and resistance in controlling the
pivot of the saw back toward the operator if kickback
occurs.
CHAIN BRAKE
The chain brake is designed to stop the chain in the
event of kickback.
NOTE: We do not represent and you should not
assume that the chain brake will protect you in the
event of a kickback. Do not rely upon any of the
devices built into your saw. You should use the saw
properly and carefully to avoid kickback.
Repairs on a chain brake should be made by an
authorized servicing dealer. Take your unit to the place
of purchase if purchased from a servicing dealer, or to
the nearest authorized master service dealer.
ASSEMBLY
a WARNING: If received assembled, repeat
all steps to ensure your saw is properly
assembled and all fasteners are secure.
Always wear gloves when handling the
chain. The chain is sharp and can cut you
even when it is not moving!
REMOVING THE CLUTCH COVER
NOTE: Chain brake must be unlocked before
clutch cover can be removed or reinstalled on the
chain saw. To unlock chain brake, pull the front
hand guard back toward the front handle as far as
SRVVLEOHVHHLOOXVWUDWLRQ
1. Check that the chain brake is in the unlocked
position by pulling the front hand guard towards
the front handle.
2. Loosen and remove guide bar retaining
knob completely by lifting lever and turning
counterclockwise.
3. Remove clutch cover.
NOTE: If clutch cover can not be easily removed
from the chain saw, ensure chain brake is unlocked
by pulling the front hand guard back toward the
front handle as far as possible.

ATTACHING THE BUMPER SPIKE
(if not already attached)
The bumper spike may be used as a pivot when
making a cut. Attach the bumper spike with the two
screws as illustrated.
ATTACHING THE GUIDE BAR
(If not already attached)
An adjusting pin and chain tensioning ring is used to
adjust the tension of the chain. It is very important
when assembling the bar that the adjusting pin
located on the adjusting screw aligns into a hole in
the bar. Turning the chain tensioning ring will move
the adjusting pin up and down the screw. Locate this
adjusting pin before you begin mounting the bar onto
the saw. See following illustration.

5. ,QVWDOOWKHJXLGHEDUUHWDLQLQJNQRE¿QJHUWLJKW
only. Once the chain is tensioned, you will need to
tighten guide bar retaining knob.
TENSIONING THE CHAIN
(Including units with chain already installed)
a WARNING: If the 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.
Chain tension is very important. Chains stretch during
XVH7KLVLVHVSHFLDOO\WUXHGXULQJWKH¿UVWIHZWLPHV
you use your saw. Always check chain tension each
time before you start the chain saw.
:KHQ¿WWLQJDQHZFKDLQWKHFKDLQWHQVLRQKDVWREH
checked frequently until the chain is run-in.
A correctly tensioned chain ensures good cutting
performance and long life.
CHECKING THE TENSION
Use a screwdriver to move chain around guide bar. If
the chain does not rotate, it is too tight. If the chain is
too loose, it will sag below the bar.
NOTE: The chain is tensioned correctly when
the weight of the chain does not cause it to sag
below the guide bar (with the chain saw sitting in
DQXSULJKWSRVLWLRQEXWWKHFKDLQVWLOOPRYHVIUHHO\
around the guide bar.
ADJUSTING THE TENSION
1. Lift lever on guide bar retaining knob and turn
counterclockwise 1 turn to loosen clutch cover.
NOTE: When adjusting chain tension, make sure
WKHJXLGHEDUUHWDLQLQJNQRELV¿QJHUWLJKWRQO\
Attempting to tension the chain when the guide bar
retaining knob is tight can cause damage.
2. Turn tensioning ring clockwise until chain solidly
contacts bottom of guide bar rail.

CHAIN BRAKE
a 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 0.5 mm (0.020 in) 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 authorized master service dealer.
This saw is equipped with a chain brake. The brake is
designed to stop the chain if kickback occurs.
The inertia-activated chain brake is locked if the front
hand guard is pushed forward, either manually (by
KDQGRUDXWRPDWLFDOO\E\VXGGHQPRYHPHQW
If the brake is already locked, it is unlocked by pulling
the front handguard back toward the front handle as
far as possible.
When cutting with the saw, the chain brake must be
unlocked.
BRAKING FUNCTION CONTROL
NOTE: 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.

wooden surface.
3. Release your grip on the front handle and use the
weight 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.
WORKING TECHNIQUES
PRACTICING YOUR CUTS
Practice cutting a few small logs using 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.
• Allow the chain to cut for you. Exert only light
downward pressure. If you force the cut, damage to
the guide bar, chain, or engine can result.
• 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 to the chain, guide
bar, and engine. It is recommended that the engine
not be operated for longer than 30 seconds at full
throttle.
• To avoid losing control when cut is complete, do not
put pressure on saw at end of cut.
• Stop the engine before setting the saw down after
cutting.
FELLING A TREE
PLANNING
a 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. If the tree makes
contact with any utility line, the utility
FRPSDQ\VKRXOGEHQRWL¿HGLPPHGLDWHO\
Carefully plan your sawing operation in advance.
Clear the work area. You need a clear area all around
the tree so you can have secure footing.
The chainsaw 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 direction.
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 of a tree might not be
apparent due to uneven or sloping terrain. Use a
plumb or level to determine the direction of tree lean.
• Weight and branches on one side.
• Surrounding 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 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.
Remove dirt, stones, loose bark, nails, staples, and
wire from the tree where cuts are to be made.

USING THE NOTCH METHOD
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 tree 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.
Make the notch cut by cutting the top of the notch
¿UVW&XWWKURXJKRIWKHGLDPHWHURIWKHWUHH1H[W
complete the notch by cutting the bottom of the notch.
Once the notch is cut remove the notch of wood from
the tree.
After removing the wood from the notch, make the
felling cut on the opposite side of the notch. This is
GRQHE\PDNLQJDFXWDERXWFHQWLPHWHUVLQFKHV
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.
NOTE: Before felling cut is complete, use wedges to
open the cut if necessary to control the direction of
fall. To avoid kickback and chain damage, use wood
or plastic wedges, but never steel or iron wedges.
Be alert to signs that the tree is ready to fall: cracking
sounds, widening 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 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 size.
a 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:
• Cut only one log at a time.
• Cut shattered wood very carefully; sharp pieces of
ZRRGFRXOGEHÀXQJWRZDUGRSHUDWRU
• 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
RXWH[SRVHGDQGFOHDUHGORJV¿UVW
• Make sure the chain will not strike the ground or
any other object during or after cutting.
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.
TYPES OF BUCKING CUTS
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
111111
log with top of saw against the log. When undercutting
XVHOLJKWXSZDUGSUHVVXUH+ROGVDZ¿UPO\DQG
maintain control. The saw will tend to push back
toward you.
a WARNING! Never turn saw upside down to
undercut. The saw cannot be controlled in
this position.

LIMBING AND PRUNING
a 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 position which can cause you
to lose your balance or control of the saw.

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 caution 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
LQWKHZRRG¿EHUVLVUHOHDVHG
• Keep a clear work area. Frequently clear
branches out of the way to 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.
Keep the tree between you and the chain. Cut from
the side of the tree opposite the branch you are
cutting.
Remove larger, supporting branches with the cutting
techniques described in BUCKING WITHOUT A
SUPPORT.
Always use an overcut to cut small and freely hanging
limbs. Undercutting could cause limbs to fall and pinch
the saw.
PRUNING
a 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.

CARBURETTOR ADJUSTMENT
a WARNING: The chain will be moving
during most of this procedure. Wear your
protective equipment and observe all safety
precautions. The chain must not move at idle
speed.
Indications for idle speed adjustment
The carburetor has been carefully set at the factory.
Adjustments may be necessary if you notice any of the
following conditions:
• The chain moves at idle. See IDLE SPEED-T
ADJUSTMENT procedure.
• The saw will not idle. See IDLE SPEED-T
ADJUSTMENT procedure.
Idle speed-T adjustment
Allow the engine to idle. If the chain moves, the idle is
too fast. If the engine stalls, the idle is too slow.
Adjust the speed until the engine runs without chain

TO SHARPEN THE SAW CHAIN
The cutter
The cutting part of the saw chain is called the cutter and
consists of a cutting tooth (A) and the depth gauge (B).
The cutters cutting depth is determined by the difference
in height between the two, the depth gauge setting (C).
When you sharpen a cutting tooth there are four important
factors to remember:
• Filing angle.
• Cutting angle.
• File position.
• 5RXQG¿OHGLDPHWHU

4. File all the teeth to the same length. When the length
of the cutting teeth is reduced to 4 mm (5/32”) the saw
chain is worn out and must be replaced.
To adjust the depth gauge setting
Sharpen the cutting teeth before you adjust the depth
gauge setting. When you sharpen the cutting tooth (A), the
depth gauge setting (C) will decrease. To maintain optimal

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.

To maintain guide bar:
1. Loosen and remove bar nuts and clutch cover.
Remove bar and chain from saw.
2. Clean the oil holes (A) and bar groove (B).
