SAFETY

a WARNING! Always disconnect spark plug

wire and place wire where it cannot contact

spark plug to prevent accidental starting

when setting up, transporting, adjusting

or making repairs except carburettor

adjustments.

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-

hand encircling and your left thumb under the front

handlebar. Keep your right hand completely around

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.

be near the correct position.

2. Slide guide bar with chain on bar bolts until guide

bar stops against clutch drum sprocket. Cutters

must face in the direction of rotation.

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

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.

the log. The compression side of the log is where the

pressure of the log’s weight is concentrated.

BUCKING WITHOUT A SUPPORT

1. Overcut through 1/3 of the diameter of the log.

2. Finish with your second cut.

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

side.

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.

Check the condition of guide bar each time chain is

sharpened. A worn guide bar will damage the chain and

PDNHFXWWLQJGLI¿FXOW

After each use, push the ON/STOP switch down until the

engine stops, then clean all sawdust from the guide bar

and sprocket hole.

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).
