ARNING! Under no circumstances may the design of the machine be modified without the permission of the manufacturer. Always use original accessories. Non-authorized modifications and/or accessories can result in serious personal injury or the death of the operator or others.
ARNING! 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 the contents of this operator’s manual.
ARNING! The inside of the muffler contain chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged muffler.
ARNING! Long term inhalation of the engine’s exhaust fumes, chain oil mist and dust from sawdust can represent a health risk.
ARNING! This machine produces an electromagnetic field during operation. This field may under some circumstances interfere with active or passive medical implants. To reduce the risk of serious or fatal injury, we recommend persons with medical implants to consult their physician and the medical implant manufacturer before operating this machine.

ways use common sense
It is not possib le to cover every conceivab le situation you can f
ace when using a chain saw. Always exercise care and use your common sense. Avoid all situations which you consider to be beyond your capability. If you still feel uncertain about operating procedures after reading these instructions, you should consult an expert before continuing. Do not hesitate to contact your dealer or us if you have any questions about the use of the chain saw. We will willingly be of service and provide you with advice as well as help you to use your chain saw both efficiently and safely. Attend a training course in chain saw usage if possible. Your dealer, forestry school or your library can provide information about which training materials and courses are available.

• To release the chain brake pull the front hand guard bac

• Kickback can be very sudden and violent. Most
kbacks are minor and do not always activate the
kic chain brake. If this happens you should hold the chain saw firmly and not let go.
• This movement activates a spring-loaded mechanism that tightens the br drive system (D) (clutch drum).
• The front hand guard is not designed solely to activate the chain br reduces the risk of your left hand hitting the chain if you lose grip of the front handle.

GENERAL SAFETY PRECAUTIONS
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 y our left hand.
• In the felling position the left hand is in a position that es manual activation of the chain brake
mak impossible. With this type of grip, that is when the left hand is placed so that it cannot affect the movement of the front hand guard, the chain brake can only be activated by the inertia action.

Will my chain brake always protect me from injury in the event of a kickback?

No. First, the chain brake must be in working order to provide the intended protection. Second, it must be activated during the kickback as described above to stop the saw chain. Third, the chain brake ma y be activated b ut if the bar is too close to you the brake might not have enough time to slow down and stop the chain before the chain saw hits you.
Only you and proper working technique can eliminate kickback and its danger.

Throttle lockout

The throttle lockout is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you g rasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. This arrangement means that the throttle control is automatically locked at the idle setting.
A

Will my hand always activate the chain brake during a kickback?

No. It takes a certain force to move the hand guard forward. If your hand only lightly touches the front guard or slips over it, the force ma y not be enough to trigger the chain brake. You should also maintain a firm grip of the chain saw handles while working. If you do and experience a kickback, your hand may never leave the front handle and will not activate the chain brake, or the chain brake will only activate after the saw has swung around a considerable distance. In such instances, the chain brake might not have enough time to stop the saw chain before it touches you.
There are also certain positions in which your hand cannot reach the front hand guard to activ brake; for example, when the saw chain is held in felling position.
ate the chain

Will my inertia activated chain brake always activate during kickback in the event of a kickback?

No. First y our brak e m ust be in w orking order . Testing the brake is simple, see instructions under the heading Checking, maintaining and servicing chain saw safety equipment. We recommend you do bef ore you begin each work session. Second the kickback must be strong enough to activate the chain brake. If the chain brake is too sensitive it would activate all the time which would be a nuisance.
B

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 instructions under the heading Assembly) and if the bar and chain are properly serviced and maintained (see instructions under the heading General working instructions).

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.

Vibration damping system

Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier.
The machine transfer of vibration between the engine unit/cutting equipment and the machine chain saw, including the cutting equipment, is insulated from the handles by vibration damping units.
Cutting hardwoods (most broadleaf trees) creates more vibr with cutting equipment that is blunt or faulty (wrong type or badly sharpened) will increase the vibration level.

Muffler
The muffler is designed to keep noise levels to a minim um and to direct exhaust fumes away from the user.
WARNING! The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material!
In areas with a hot, dry climate there is a high risk of fires. These areas are sometimes subject to go requiring among other things the muffler must be equipped with an approved type of spark arrestor mesh.

damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such 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. These symptoms may be increased in cold temperatures.

Stop switch

Use the stop switch to switch off the engine.
CAUTION! The muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when working near flammable substances and/or vapours.
WARNING! Never use a saw without a muffler, or with a damaged muffler. A damaged muffler may substantially increase the noise level and the fire hazard. Keep fire fighting equipment handy. If a spark arrestor screen is required in your area, never use the saw without or with a broken spark arrestor screen.

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 saw chain breaking or jumping off the bar
• Obtain optimal cutting performance.
• Extend the life of cutting equipment.
• Avoid increasing vibration levels.

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 chips will be very small. If the chain is very blunt it will produce wood powder and no chips or shavings.
