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 too 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.

Ifthe 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.

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.

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.

Starting The chain brake must be

engaged when starting.

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).

To release the chain brake pull the front hand guard

backwards, towards the front handle.

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 ifthe 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.

When the 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.

2 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

Make sure the throttle control is locked at the idle setting when you

release the throttle lock.

Press the throttle lock and

make sure it returns to its original position when you

release it.

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.

Start the saw 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".

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

SAFETY INSTRUCTIONS

7 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.

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

Only use cutting equipment

recommended by us!

See the "Technical data"

section.

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.

Maintain the correct

raker clearance! Follow our instructions and

use the recommended

raker gauge. Too large a

clearance increases the

risk of kickback.

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.

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.

10- English

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

SAFETY INSTRUCTIONS

2 Sharpening your chain and adjusting

raker clearance

A General information on sharpening cutting teeth

• Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the cuttings will be very small. If the chain is very blunt it will not produce any cuttings at all, just wood powder.

• A sharp chain eats its way through the wood and produces long, thick cuttings.

• The cutting part of the chain is called the CUTTING LINK

and this consists of a CUTTING TOOTH (A) and

the RAKER LIP (B). The cutting depth is determined

by the difference in height between the two.

It is very difficult to sharpen a

chain correctly without the

right equipment. We recommend you use a file

gauge. This will help you obtain the maximum kickback

reduction and cutting performance from your chain.

B Sharpening cutting teeth

• When you sharpen a cutting tooth there are five important factors to remember.

FILING ANGLE

CUTTING ANGLE

FILE POSITION

ROUND FILE DIAMETER

FILE DEPTH

To sharpen cutting teeth you will need a ROUND FILE and

a FILE GAUGE. See the

"Technical data" section for

information on the size of file

and gauge that are

recommended for your saw

chain.

Check that the chain is correctly tensioned. A

slack chain is difficult to sharpen correctly.

Always file cutting teeth from the inside face,

reducing the pressure on

the return stroke.

File all the teeth on one side first, then turn the saw over and file the teeth on the other side.

File all the teeth to the same length. When the

length of the cutting teeth

is reduced to 4 mm

(0,16") the chain is worn out and should be

replaced.

___°_°_

min 4 mm

See the "Technical data"section for information about

sharpening your saw chain.

12 - English

SAFETY INSTRUCTIONS

C General advice on setting raker clearance

• When you sharpen the

cutting teeth you reduce the RAKER CLEARANCE

(cutting depth). To maintain cutting performance you

must file back the raker

teeth to the recommended

height. See the "Technical data"

section to find the raker clearance for your saw

chain.

• On a low-kickback cutting link the front edge of the raker lip is rounded. It is very important that you

maintain this radius or bevel

when you adjust the raker

clearance.

• We recommend the use of a raker gauge to achieve the

correct clearance and bevel on the raker lip.

D Setting the raker clearance

Before setting the raker clearance the cutting teeth should be newly sharpened. We recommend that you adjust the raker clearance every

third time you sharpen the chain. NOTE! This

recommendation assumes that the length of the cutting teeth is not reduced excessively.

To adjust the raker clearance you will need a

FLAT FILE and a RAKER GAUGE.

• Place the gauge over the raker lip.

Place the file over the part of the lip that protrudes

through the gauge and file

off the excess. The clearance is correct when

you no longer feel any resistance as you draw the

file over the gauge.

3 Tensioning the chain

The more you use a chain the longer it becomes. It is

therefore important to adjust the chain regularly to take up the

slack.

Check the chain tension every time you refuel. NOTE! A new saw chain has a running-in period during which you should check the tension more frequently.

Tension the chain as tightly as possible, but not so tight

that you cannot pull it round freely by hand.

English - 13

SAFETY INSTRUCTIONS

Undo the bar nuts that hold the clutch cover and

chain brake, using the combination spanner. Then tighten the nuts by

hand as tight as you can.

Raise the tip of the bar and stretch the chain by tightening the chain tensioning screw using the combination spanner. Tighten the chain until it

not hang slack on the

underside of the bar.

3 Use the combination

spanner to tighten the bar

nuts while lifting the tip of the bar at the same time.

Check that you can pull the chain round freely by

hand and that it is not slack on the bottom of the

bar.

The position of the chain tensioning screw varies from

model to model. See the" What is what" section to find out where it is on your saw.

4 Lubricating cutting equipment

A Chain oil

• Chainsaw chain oil must demonstrate good adhesion to the chain and also maintain its flow caracteristics regardless of

whether it is warm summer or cold winter weather.

As a chainsaw manufacturer we have developed an optimal chain oil which has a vegetable oil base. We recommend the

use of our own oil for both maximum chain life and to minimise environmental damage.

• If our own chain oil is not available, standard chain oil is recommended.

• In areas where oil specifically for lubrication of saw chains is unavailable, ordinary EP 90 transmission oil may be used.

• Never use waste oil! This is dangerous for yourself, the saw and the environment.

B Filling with chain oil

• All our chain saws have an automatic chain lubrication

system. On some models the oil flow is also

adjustable.

The sizes of the chain oil tank and fuel tank have been chosen so that the saw will run out of fuel

before running out of oil. This means that you should never run with a dry chain.

However, this safety feature requires that you use the right sort of chain oil (if the

oil is too thin it will run out before the fuel), and that

you adjust the carburetor as recommended (a weak

mixture may mean that the fuel lasts longer than the

oil). You should also use the recommended cutting

equipment (a bar that is too long will use more chain oil).

The above conditions also apply to models with an

adjustable oil pump.
