• Chainsaws are potentially dangerous tools.

Professional training is recommended before first

use.

• If you are not familiar with chainsaws and the

felling of trees, it is recommended that you

obtain further more detailed instructions and

information regarding chain-sawing in addition

to reading this manual fully. We also recommend

that inexperienced chainsaw users practice

cutting logs on a saw-horse or log cradle before

attempting to fell a tree.

• Keep work area clean.

• Do NOT start cutting until you have a clear work

area, secure footing and a planned, clear escape

path from the falling tree or limb.

• Use extreme caution when cutting small size

brush and saplings because the slender material

may catch the saw chain and be whipped toward

you or pull you off balance.

• Do NOT operate a chainsaw at height in a tree

or on a ladder unless specifically trained to do so.

• When cutting a limb that is under tension, be

alert for spring back so that you will not be

struck when the tension in the wood fibres is

released.

• Do NOT expose the chainsaw to rain.

• Do NOT use the chainsaw in damp or wet

conditions.

• Do NOT use the chainsaw in presence of

flammable liquids or gases.

• Keep children, bystanders and pets away from

the work area.

• When not in use, chainsaws should be stored in a

dry, secure location – well out of the reach of

children.

• Always fit the chain guard when not in use.

• Never force the chainsaw - it will do the job better and

safer when used correctly.

• Only suitable for use to cut wood with a diameter

smaller than the length of the guide bar.

• Do NOT use chainsaw for cutting plastic, masonry,

non-wood building materials.

• Do NOT use the chainsaw for any use other than the

intended use described in these instructions.

• Make sure you are suitably dressed when using the

chainsaw with correct standard Personal Protective

Equipment.

• Do NOT wear loose clothing or jewellery that can get

caught in moving parts. Heavy duty gloves and sturdy

non-slip work boots are recommended when working

outdoors.

• Wear a hairnet to contain long hair which can get

caught in moving parts.

• Always wear suitable head, ear and eye protection.

• Carry the chainsaw by the front handle with the saw

stopped, your finger off the trigger and the guide bar

and saw chain to your rear.

• Periodically inspect chainsaw for damage. Do NOT use

if damaged in any way.

• Always clean after use and replace worn parts when

performance becomes reduced.

• Do not smoke while handling fuel or while operating

the chainsaw.

• Follow instructions for lubricating and changing

accessories.

• Keep handles dry, clean and free from oil and grease.

• Turn off the chainsaw when not in use, before servicing

or cleaning, and when changing accessories and

attachments, such as saw chain and guard.

• Stay alert, watch what you are doing. Always use

common sense.

Warning

• Do NOT operate chainsaw when you are tired, ill

or under the influence of alchol or drugs.

• Using a chainsaw can be strenuous. Remember to

take regular breaks. Tiredness may result in loss of

control.

• Keep all parts of the body away from the chain

when the chainsaw is switched on.

• Before you start the saw, make sure the saw chain

is not in contact with anything.

• Always check for damaged parts before first and

every use or if the chainsaw is dropped. Do NOT

use if any part is damaged in any way. Check for

alignment of moving parts, binding of moving

parts, breakage of parts, mounting and any other

conditions that may affect operation. Any part that

is damaged should be properly repaired or replaced

by an authorised service centre unless otherwise

indicated elsewhere in this instruction manual.

• Regularly check that all the fixings are secure as

vibrations in use may cause them to loosen over

time.

• When servicing, use only identical replacement

parts.

• Do NOT use the chainsaw if the switch does not

turn it on and off.

• Do NOT operate a chainsaw that is damaged,

improperly adjusted, or is not completely and

securely assembled. Be sure that the saw chain

stops moving when the trigger is released before

using to cut wood.

• Guard against kickback.

• Only use replacement bars and chains specified by

the manufacturer or the equivalent.

• For outdoor domestic use only.

Warning

RESIDUAL RISKS

Despite the above warnings and due to the nature of

the product, there remains a residual risk, which

cannot be prevented when using a chainsaw. The

following potential hazards might apply:

• Contact with exposed saw teeth of the saw chain

(cutting hazards).

• Access to the rotating saw chain (cutting hazards).

• Unforeseen, abrupt movement of the guide bar

(cutting hazards.)

• Parts flung out from the saw chain (cutting/injection

hazards).

• Wood splinter ejection.

• Inhalation of wood particles and dust - there may

be health risks caused by breathing in dust,

especially dust generated from sawing oak, beech

and MDF.

• Skin contact with the lubricating oil.

• Loss of hearing, if ear protection is not worn.

INTENDED/UNINTENDED USE

When using the chainsaw, the user must arrange to

use personal protective equipment according to the

manual. Parts of the intended use are detailed in the

manual’s safety warnings and references for use by

those who work with the chain saw or maintain it,

therefore the user must be familiar with the manual.

Only use original or approved spare parts (e.g. guide

bar; saw chain).

Warning

Vibration Warning!

Prolonged use of chainsaws or any other machine

that vibrates in use, may produce a medical condition

called “white finger disease”, “Raynaud’s

phenomenon”, or “carpal tunnel syndrome”.

These conditions can cause numbness, burning

sensations and circulation damage, and may reduce

the hand’s ability to feel and regulate temperature.

The factors that contribute to these conditions are

not fully known, but high vibrations may be a cause.

Users should take precautions to minimise the risks

which include:

• Wear gloves

• Keep hands warm

• Take breaks from prolonged use

• Keep the chain saw sharp so that it operates as

smoothly as possible

• Maintain a firm grip but do not squeeze too tight

and for too long at any one time.

Continual and regular users should monitor their

hands and fingers and if any symptoms occur, or if

you are worried at any time, cease use and consult

your medical practitioner for further advice.

Warning! Restriction of use.

Please check with your local authority before using a

chainsaw as there may be regulations in force that

restrict their use e.g. in times of drought.

Warning! Hearing protection.

It is recommended that safety ear/hearing protection

is worn at all times when operating this chain saw.

Chain saw noise may damage your hearing. Regular

users should have frequent hearing tests with their

medical practitioner.

The hearing protection should be suitable for

defending hearing for the following levels:

Sound pressure level according to ISO22868

LPA:108dB(A).

Sound pressure level according to ISO22868 LWA:

<116dB(A)

Inhalation Warning!

Using the chainsaw may generate dust, mist and

fumes containing chemicals that could be harmful to

the user. Dust alone may also be harmful and should

not be inhaled. Never use the chain saw to cut

anything that is known to contain a harmful

substance such as asbestos. Always operate the

chainsaw in a well-ventilated location, preferably

outdoors. Remember that the fuel and oil used to

power and lubricate this machine will give off

harmful fumes in use, and when filling – always

ensure there is sufficient ventilation as soon as you

start the engine. A dust mask or breathing apparatus

is recommended safety equipment, and anyone with

a respiratory or other breathing medical condition is

advised to consult their medical practitioner before

using the chainsaw.

KICKBACK SAFETY PRECAUTIONS FOR CHAINSAW USERS

WARNING

Kickback may occur when the nose or tip of the guide bar touches an

object, or when the wood closes in and pinches the saw chain in the cut.

Tip contact in some cases may cause a lightning fast reverse reaction,

kicking the guide bar up and back towards the operator. Pinching the saw

chain along the top of the guide bar may push the guide bar rapidly back

towards the operator. Either of these reactions may cause you to Iose

control of the chainsaw, which could result in serious personal injury.

Do not rely exclusively on the safety devices built into your chainsaw. As a

chainsaw user you should take several steps to keep cutting jobs free from

accident or injury.

(1) With a basic understanding of kickback you can reduce or eliminate the

element of surprise. Sudden surprise contributes to accidents.

(2) Keep a good grip on the saw with both hands, the right hand on the rear

handle, and the left hand on the front handle, when the engine is running.

Use a firm grip with thumbs and fingers encircling the chain saw handles.

A firm grip will help you reduce kickback and maintain control of the saw.

(3) Make certain that the area in which you are cutting is free from

obstructions. Do not let the nose of the guide bar make contact with a

log, branch, or any other obstruction which could be hit while you are

operating the saw.

(4) Cut at high engine speeds.

(5) Do not overreach or cut above shoulder height.

(6) Follow the manufacturer’s sharpening and maintenance instructions for

the saw chain.

(7) Only use replacement bars and chains specified by the manufacturer

or the equivalent.

AVOIDING PULL-IN

Pull-in can occur when the bottom of the chain is used for

cutting and is stopped suddenly by hitting a foreign object

or getting pinched. This pulls the chainsaw forwards and

may cause the user to lose control. Pull-in can also occur

when the chain is not running at full speed when contact is

made with the wood and if the bumper spike is not held

securely against the wood being cut.

• Ensure the chain is rotating at full speed and the bumper

spike is correctly positioned when making a cut.

AVOIDING PUSHBACK

Pushback can occur when the top of the chain is used for

cutting and is stopped suddenly by hitting a foreign object

or getting pinched. This pulls the chainsaw towards the

user and may cause the user to lose control.

• Take care not to twist the chainsaw as it is removed

when bucking from underneath the log.

• Do NOT cut more than one log at any one time.

• Be aware of situations that may cause the chain to pinch

or pull.

BUMPER SPIKE

This is used to help secure the tree or limb when cutting

and should be used at all times when positioning the

chainsaw. It will help prevent pull-in, pushback, kickback

and loss of control.

Fuel and chain oil

FUEL

• Petrol is flammable.

• Always turn off the engine and allow to cool fully

before refuelling.

• Mix regular unleaded petrol and a quality 2-stroke

motor oil for air-cooled engines at a ratio of 25:1.

• Do not use 4-stroke oil.

• Do not mix fuel and oil in the petrol tank of the

chainsaw. Always use the mixing bottle supplied,

secure the lid and shake to mix.

• Keep naked flames away from where petrol is stored

or handled.

• Do not use petrol/oil mix more than 1 month old.

• Always use caution when handling fuel. Wipe up all

spills and then move the chainsaw at least 3m from

the fueling point before starting the engine.

• Eliminate all sources of sparks or flame (i.e. smoking,

open flames, or work that can cause sparks) in the

areas where fuel is mixed, poured or stored.

CHAIN OIL

Use motor oil SAE 10W-30 all year round or

SAE 30 ~ 40 in summer and SAE 20 in winter.

Warning

It is very dangerous to run a chainsaw that has any broken

or moving parts or lacks any parts. Before starting the

engine, make sure that all the parts including bar and

chain are installed properly. Check the chainsaw before

every use and do not use if damaged in any way

Do not allow other persons to be near the chain saw when

starting or cutting. Keep bystanders and animals out of the

work area. Children, pets and bystanders should be a

minimum of 10m away when you start or operate the

chainsaw.

Never start cutting until you have a clear work area, secure

footing, and a planned retreat path from the falling tree.

Before you start the engine, make sure the saw chain is not

contacting anything including the ground.

Keep the handles dry, clean and free of oil or fuel mixture.

STARTING THE ENGINE

1. Fill fuel and chain oil tanks respectively, and tighten the

caps securely (F5).

CHECKING THE OIL SUPPLY

Warning

Make sure the bar and the chain are set

up when checking the oil supply. If not,

the rotating parts may be exposed and

this is very dangerous. After starting the

engine, run the chain at medium speed

and see if chain oil is scattered off as

shown (F10).

The chain oil flow can be changed by

inserting a screwdriver in the hole on

bottom of the clutch side. Adjust

according to your work conditions (F11).

(1) Heavy flow

(2) Light flow

(3) Chain oil flow adjusting hole

Note

The oil tank should become nearly

empty by the time fuel is used up. Be

sure to refill the oil tank every time

when refueling the chainsaw.

ADJUSTING THE CARBURETOR (F12)

The carburetor on your unit has been

factory adjusted but may require fine

tuning due to a change in operating

conditions. Before adjusting the

carburetor, make sure that the provided

air/fuel filters are clean and fresh and

the fuel properly mixed.

L needle: 1

+ or –

2. Start the engine and allow it to warm up in low

speed for a few minutes.

3. Turn L needle slowly clockwise to find a position

where the idling speed is maximum then move

the needle back a quarter turn anti-clockwise.

4. Turn the idle adjusting screw T anti-clockwise so

that the saw chain does not turn. If the idling

speed is too slow, turn the screw clockwise.

5. Make a test cut and adjust the H needle for best

cutting power, not for maximum speed.

CHAIN BRAKE

This machine is equipped with an automatic brake

to stop saw chain rotation upon occurrence of

kickback during saw cutting. The brake is

automatically operated by inertial force, which acts

on the weight fitted inside the front guard.

This brake can also be operated manually with the

front guard turned down to the guide bar.

To release the brake, pull up the front guard toward

the front handle till “click” sound is heard (F13).

Operation

(F12)

(F13)

CLUTCH

To check the operation of the clutch run the saw at idle

speed and there shoud be no movement of the chain. If

chain moves there may be clutch wear or idle is

adjusted too high.

Important

[Caution]

Check brake operation before each use.

How to confirm:

1) Turn on the engine.

2) Holding the chain saw horizontally, release your hand from the front

handle, hit the tip of the guide bar to a stump or a piece of wood, and

confirm brake operation. Operating level varies by bar size (F14).

If the engine is kept running at high speed whilst the brake is engaged,

the clutch will overheat and become damaged.

Always hold the chainsaw firmly with both hands when the engine is

running. Use a firm grip with thumb and fingers encircling the chain saw

handles.

Keep all parts of your body away from the saw chain when the engine is

running.

All chainsaw service, other than the items listed in the Instructions, should

be performed by competent chainsaw service personnel. (e.g., if improper

tools are used to remove the flywheel, or if an improper tool is used to

hold the flywheel in order to remove the clutch, structural damage to the

flywheel could occur which could subsequently cause the flywheel to

disintegrate.)

Always turn off the engine before putting the chainsaw down.

Use extreme caution when cutting small size brush and saplings because

slender material may catch the saw chain and be whipped toward you or

pull you off balance, or stop the chain.

When cutting a limb that is under tension, be alert for spring-back so that

you will not be struck when the tension in the wood fibres is released.

Kickback is the upward motion of the guide bar which occurs when the

saw chain at the nose of the guide bar makes contact with an object.

Kickback can lead to dangerous loss of control of the chainsaw.

STOPPING THE ENGINE

1. Release the throttle lever to allow the engine to idle for a few minutes.

2. Set the switch to the "O" (STOP) position (F15).

3. Be aware that the chain will continue to move for a short time after the

engine has stopped.

Warning

Before proceeding to your job, read For Safe

Operation section p7-8. It is recommended to first

practice sawing easy logs. This also helps you get

accustomed to your unit. Always follow the safety

regulations. The chainsaw must only be used for

cutting wood. It is not suitable for cutting any other

type of material. Vibrations and kickback vary with

different types of woods. Do not use the chainsaw

as a lever for lifting, moving or splitting objects. It is

not necessary to force the saw into the cut. Apply

only light pressure while running the engine at full

throttle. When the saw chain is caught in the cut,

do not attempt to pull it out by force, but use a

wedge or a lever to open the way. Do not fit any

other tools to the chainsaw or use for any other

purpose other than those specified in these

instructions.

GUARD AGAINST KICKBACK (F15)

This saw is equipped with a chain brake that will stop

the chain in the event of kickback if operating

properly. You must check the chain brake operation

before each usage by running the saw at full the

throttle for I – 2 seconds and pushing the front hand

guard forward. The chain should stop immediately

with the engine at full speed. If the chain is slow to

stop or does not stop, replace the brake band and

clutch drum before use.

It is extremely important that the chain brake be

checked for proper operation before each use and

that the chain be sharp in order to maintain the

kickback safety level of this saw. Removal of the

safety devices, inadequate maintenance, or incorrect

replacement of the bar or chain may increase the risk

of serious personal injury due to kickback and will

invalidate your warranty (F15).

Sawing

Once the direction of fall is determined, clear two

escape routes. These should be in the opposite

direction to the planned direction of fall and

approximately at 45° to the position of the undercut.

Ensure that tools and equipment do not block the

escape routes at any time.

Further precautions to be taken when felling trees:

• Take extra care when felling in the vicinity of power

lines, railway lines and roads. If the tree felling is

too dangerous to perform due to these hazards, do

NOT proceed with the felling and seek professional

advice from a qualified arborist.

• Always ensure a work area of 2½ tree lengths is

clear of people around the tree.

• Trees with large buttress roots may require the

buttress root to be cut before felling. To do this cut

vertically into the buttress root and then

horizontally until the buttress root becomes loose

and can be removed.

Felling:

• The chainsaw must be running before it comes into

contact with the wood. Switch on the chainsaw.

Saw a notch (remove a 45° wedge of trunk) up to

¼ of the depth of the trunk into a low part of the

tree trunk in the direction of the fall and then

remove the loose piece.

FELLING TREES

To fell a tree, observe all the safety regulations and

proceed as follows:

The chainsaw may be used to fell only trees with

trunks which are smaller in diameter than the length

of the guide bar. If the saw chain gets jammed,

release it using a wooden wedge. Do not try to lever

the saw out of the cut. When felling on a slope,

always stand uphill of the tree.

Check the tree for signs of damage or decay before

felling. Decayed trees can split during felling and dead

or loose branches could free themselves through the

vibrations of the sawing action. Felling trees is

dangerous and requires practice. If you are a beginner

or inexperienced using chainsaws seek professional

training.

First determine the likely direction of fall using the

following criteria:

• The intended direction of fall.

• The wind direction and wind speed.

• The natural lean of the tree.

• Slope of the ground.

• Any surrounding tree or building which may

obstruct, deflect or cause the falling tree to change

direction.

• Any other factors, such as uneven branch

configuration which could cause the tree to be

heavier on one side than the other.

Bucking and Limbing

Bucking is cutting a fallen log into smaller

lengths. Limbing is the removal of branches

from a fallen tree.

Warning

Always ensure you have a firm foothold. Do not

stand on the log. Be alert to the rolling over of a cut

log. Especially when working on a slope, stand on

the uphill side of the log. Follow the instructions in

For Safe Operation p.7-8 to avoid kickback of the

chainsaw.

Before starting work, check the direction of bending

force inside the log to be cut. Always finish cutting

from the opposite side of bending direction to prevent

the guide bar from being caught in the cut.

Sawing

(F17)

(F18)

(F19)

Felling: (continued)

• Make a horizontal cut on the side opposite to the

notch; ensuring approximately a tenth of the

diameter of the trunk is not sawn, forming a hinge

which will allow the tree to fall in a controlled

manner. Do NOT cut all the way through the

hinge as this could de-stabilise the falling tree.

• Always stand to the side of the falling tree, never

behind it.

• When the tree begins to fall, remove the chainsaw,

switch the chainsaw off, call a warning of “Timber!”,
