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. 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! Under no circumstances may the design of the machine be modified without the permis­sion of the manufacturer. Always use genuine spare parts/accessories. Non-authorized modifications and/or accessories can result in serious personal injury or the death of the operator or others.
Your warranty may not cover damage or liability caused by the use of non-authorized accessories or replacement parts.
A chain saw is a dangerous tool if used carelessly or incorrectly and can cause serious, even fatal injuries. It is very important that you read and understand these instructions.

SAFETY INSTRUCTIONS

PERSONAL PROTECTIVE EQUIPMENT
MOST CHAIN SAW ACCIDENTS HAPPEN WHEN THE CHAIN TOUCHES THE OPERA­TOR. You must wear approved safety equipment whenever you use a chain saw. Personal safety equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your chain saw dealer for help in choosing the right equipment.

SAFETY INSTRUCTIONS
1 Chain brake and front hand guard
YOUR chain saw is equipped with a chain brake that is desig­ned 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.
1 The chain brake (A) can
either be activated manually (by your left hand) or automatically by the inertia release mechanism (a free­swinging pendulum). On most of our models the front hand guard acts as a counterweight in case of kickback.
A
B
3a Starting
The chain brake should be activated 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).
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.
C
D
B
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
6 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 opera­tion 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
chain are properly serviced and maintained. (See section on
workinginstructions
) and if the bar and
General
).
A
B
7 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.
Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. These symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the fingers, hands or wrists.
The exhaust fumes from the engine are very hot and may contain sparks which can start a fire. Never start the saw indoors or near combustible material!
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
).
The muffler gets very hot in use and remains so for a short time afterwards. DO NOT TOUCH THE MUFFLER IF IT IS HOT!
WARNING! The catalytic converter muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when handling the saw near flammable substances or vapours.

SAFETY INSTRUCTIONS
Inspecting, maintaining and servicing chain saw safety equipment
SPECIAL TRAINING IS REQUIRED to service and repair chain saws. This is especially true of chain saw safety equipment. If your chain saw fails any of the checks described below take it to your SERVICE AGENT. When you buy any of our products we guarantee the availability of professional repairs and service. If the retailer who sells your saw is not a SERVICING DEALER, ask him for the address of your nearest SERVICE AGENT.
1 Chain brake and front hand guard
1 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.
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.
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.
4 Checking the brake trigger
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.
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
4 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
3 Chain catcher
Check that the CHAIN CATCHER is not damaged and is firmly attached to the body of the saw.
Make sure the vibration damping units are securely attached to the engine unit and handles.
6 Stop switch
.
Start the engine and make sure the engine stops when you move the stop switch to the stop setting.

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
1 Only use cutting
equipment recommended by us!
See the 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.
Technical data
NEVER USE A CHAIN SAW WITH FAULTY SAFETY EQUIPMENT. CARRY OUT THE CHECKS AND MAINTENANCE MEASURES DESCRIBED IN THIS SECTION. IF YOUR CHAIN SAW FAILS ANY OF THESE CHECKS CONTACT YOUR SERVICE AGENT TO GET IT REPAIRED.
3 Maintain the correct
raker clearance! Follow our instructions and use the recommended raker gauge. Too large a
clearance increases the risk of kickback.
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.
10 – English
SAFETY INSTRUCTIONS
1 Cutting equipment designed to minimise
kickback
Faulty cutting equipment or the wrong combination of bar and chain increases the risk of kickback. Use only the bar and chain combinations recommended in the
section.
data
The only way to avoid kickback is to make sure that the kick­back 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.
