CONTENTS

Before using a new saw

• Read the instructions carefully.

• Check cutting equipment is correctly fitted and adjusted. See page 25.

• Refuel and start the saw. Check the carburetor settings. See pages 26-29.

• Do not use the saw until sufficient chain oil has reached the chain, see page 14.

IMPORTANT! If the carburetor mixture is tee lean it greatly increases the risk of engine failure. Poor maintenance of the air filter will cause carbon build-up on

the spark plug and lead to difficult starting.

If the chain is badly adjusted it will cause increased wear or

damage to the bar, drive sprocket and chain.

Maintenance, replacement, or repair of the emission

control devices and systems may be performed by any

nonroad engine repair establishment or individual.

WARNING

The engine exhaust from this product

contains chemicals known to the State

of California to cause cancer, birth

defects or other reproductive harm.

SAFETY INSTRUCTIONS

1 Chain brake and front hand guard

YOUR chain saw is equipped with a chain brake that is desig-

ned to stop the chain immediately if you get a kickback.

The chain brake reduces the risk of accidents, but only You can

prevent them.

Take care when using your saw and make sure the

kickback zone of the bar never touches any object.

The chain brake (A) can either be activated

manually (by your left hand) or automatically by

the inertia release

mechanism (a free-

swinging pendulum). On

most of our models the

front hand guard acts as a counterweight in case of

kickback.

2 The front hand guard is

not designed solely to activate the chain brake.

Another important safety feature is that it prevents

the chain from hitting your left hand if you lose your

grip on the front handle.

3a Starting

The chain brake must be engaged when starting.

b You can also use the

chain brake as a temporary brake when you

change position or if you put the saw down for a short time. You should

also apply the chain brake manually if there is a risk

of the chain accidentally hitting anyone or anything

close by.

The brake is applied when the front hand

guard (B) is pushed forwards.

This movement activates a spring-loaded

mechanism that tightens the Brake Band (C) around the engine drive system (D) (Clutch Drum).

4 To release the chain brake

pull the front hand guard backwards, towards the front handle.

5 As mentioned in section A,

kickback can be very sudden and violent.

Most kickbacks are minor and do not always

activate the chain brake. If this happens you

should hold the chain saw firmly and not let

go.

English = 5

SAFETY INSTRUCTIONS

The way the chain brake is triggered, either manually or automatically, depends on the force of the kickback and the position of the chain saw in relation to the object that the

kickback zone of the bar strikes.

If you get a violent kickback while the

kickback zone of the bar is farthest away from you

the chain brake will be activated by the

movement of the counterweight (INERTIA

ACTIVATED).

If the kickback is less violent or the kickback

zone of the bar is closer to you the chain brake will

be activated manually by the movement of your left

hand.

2 Throttle lock

The throttle lock is designed to prevent accidental opera-

tion of the throttle control. When you press the lock (A)

(i.e. when you grasp the handle) it releases the throttle trigger (B). When you release the handle the throttle trigger and the

throttle lock both move back to their original positions. This

movement is controlled by two independent return springs. This arrangement means that

the throttle control is automatically locked at the

idle setting when you release the handle.

3 Chain catcher

The chain catcher is designed to catch the chain if it snaps or

jumps off. This should not

happen if the chain is properly tensioned (see section on

"Assembly') and if the bar and

chain are properly serviced and maintained.

(See section on "General

working instructions').

During felling your left hand grasps the front handle in such a way that

it cannot activate the front hand guard. In this

position the chain brake can only be activated by

the inertia action of the counterweight.

The inertia activated chain brake increases

your safety but there are certain factors to

remember (see point 6 above).

4 Right hand guard

Apart from protecting your hand if the chain jumps or snaps, the right hand guard stops branches and twigs from interfering with your grip

on the rear handle.

6 = English

SAFETY INSTRUCTIONS

5 Vibration damping system

Your chain saw is equipped with a vibration damping system that is designed to

minimise vibrations and make

operation easier.

When you use a chain saw vibrations are generated by

the uneven contact between the chain and the wood you

are cutting.

Cutting hardwoods (most

broadleaf trees) creates more vibration than cutting softwoods (most conifers). Cutting with a chain that is

blunt or faulty (wrong type or

badly sharpened, see section

D) will increase the vibration

level

6 Stop switch

Use the stop switch to switch off the engine.

7 Muffler

The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user.

The vibration damping system

reduces the vibrations transmitted from the engine

and chain to the handles of the chain saw. The body of

the saw, including the cutting equipment, is insulated from the handles by vibration damping units.

In areas with a hot, dry climate there is a high risk of

forest fires. These areas are sometimes controlled by

legislation and requirements that among other things the muffler must be equipped with an approved type of spark

arrestor mesh.

For mufflers it is very important that you follow the instructions on checking, maintaining and servicing your saw (see the section on

"Inspecting, maintaining and

servicing chain saw safety equipment').

English = 7

SAFETY INSTRUCTIONS

Inspecting, maintaining and servicing chain saw safety equipment

Chain brake and front hand guard

Checking brake band wear

Brush off any sawdust, resin and dirt from the

chain brake and clutch drum. Dirt and wear can

impair operation of the brake.

3 Checking the inertia brake release

Hold the chain saw over a stump or other firm object.

Let go of the front handle so that the bar falls onto

the stump.

Whenthe bar hits the stump the brake should

be applied.

4 Checking the brake trigger

Regularly check that the brake band is at least 0.6

mm thick at its thinnest point.

Checking the front hand guard

A Make sure the

FRONT HAND GUARD is not damaged and

that there are no visible defects such as cracks.

Start the chain saw and place it on firm ground.

Make sure the chain does not touch the ground or

any other object.

Grasp the saw firmly, wrapping your fingers and

thumbs around the handles.

Apply full throttle and activate the chain brake

by tilting your wrist forward onto the front

hand guard. Do not let go of the front handle.

B Move the front hand

guard forwards and back to make sure it

runs freely and that it is securely anchored to

the clutch cover.

8 = English

The chain should stop

immediately.

SAFETY INSTRUCTIONS

2 Throttle lock

1 Make sure the throttle

control is locked at the

idle setting when you release the throttle lock.

2 Press the throttle lock and

make sure it returns to its

original position when you

release it.

3 Check that the throttle

control and throttle lock

move freely and that the return springs work properly.

4 Right hand guard

Check that the right hand guard is not damaged and

that there are no visible defects, such as cracks.

5 Vibration damping system

Regularly check the

vibration damping units for cracks or deformation

Make sure the vibration

damping units are securely attached to the engine unit and handles.

4 Start thesaw and apply

full throttle. Release the throttle control and check

that the chain stops and

remains stationary. If the

chain rotates when the throttle is on idle setting

you should check the carburetor idle

adjustment. See the section on "Maintenance".

3 Chain catcher

Check that the CHAIN CATCHER is not

damaged and is firmly attached to the body of

the saw.

6 Stop switch

Start the engine and

make sure the engine stops when you move the stop switch to the stop setting.

English = 9

Muffler

Never use a chain saw that has a faulty muffler.

Regularly check that the muffler is securely

attached to the chain saw.

If the muffler on your saw is fitted with a spark

arrestor mesh this must be cleaned regularly. A

blocked mesh will cause the engine to overheat

and may lead to serious damage.

Never use a muffler if

the spark arrestor mesh

is missing or defective.

SAFETY INSTRUCTIONS

CUTTING EQUIPMENT

This section describes how to choose and maintain your cutting equipment in order to:

• Reduce the risk of kickback.

• Reduce the risk of the chain breaking or jumping.

• Obtain maximum cutting performance.

• Extend the life of cutting equipment.

The 5 basic rules

1 Only use cutting

equipment

recommended by us!

See the "Technical data" section.

2 Keep the chain cutting

teeth properly

sharpened! Follow our instructions and use the

recommended file gauge. A damaged or

badly sharpened chain increases the risk of

accidents.

3 Maintain the correct

raker clearance! Follow our instructions and use the recommended

raker gauge. Too large a clearance increases the

risk of kickback.

O ©

4 Keep the chain properly

tesioned! If the chain is

slack it is more likely to

jump off and lead to

increased wear on the bar, chain and drive

sprocket.

5 Keep cutting equipment

well lubricated and properly maintained!

A poorly lubricated chain is more likely to break and

lead to increased wear on the bar, chain and drive sprocket.

SAFETY INSTRUCTIONS

1 Cutting equipment designed to minimise

kickback

The only way to avoid kickback is to make sure that the kick-

back zone of the bar never touches anything. By using cutting equipment with "built-in" kickback protection

and keeping the chain sharp and well-maintained you can

reduce the effects of kickback.

A Bar

The smaller the tip radius the smaller the kickback zone and the lower the chance of

kickback.

B Saw chain

A saw chain is made up of a number of links, which are available in standard and low-kickback versions.

None Standard Low-kickback

CUTTING LINK

C Some terms that describe the bar and chain When the cutting equipment supplied with your saw becomes

worn or damaged you will need to replace it. Use only the type of bar and chain recommended by us. See the "Technical data" section to find out which equipment is recommended for your

saw.

Bar

• LENGTH (inches/cm)

• NUMBER OFTEETH ON BAR TIP SPROCKET (T).

Small number = small tip radius = low-kickback

• CHAIN PITCH (inches)

The spacing between the drive links of the chain must

match the spacing of the teeth on the bar tip sprocket and drive sprocket.

• NUMBER OF DRIVE LINKS

The number of drive links is determined by the length of

the bar, the chain pitch and the number of teeth on the

bar tip sprocket.

• BAR GROOVE WIDTH

(inches/mm) The groove in the bar must

match the width of the chain drive links.

pITCH= D

DRIVE LINK

SIDE LINK

Combining these links in different ways gives different degrees of kickback reduction. In terms of kickback reduction alone, four

different types of link are available.
