GENERAL SAFETY PRECA UTIONS
Al ways use common sense
It is not possib le to cover every conceivable situation you can face 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.
• Boots with saw protection, steel toe-cap and non-slip sole
• Always have a first aid kit nearby.
• Fire Extinguisher and Shovel
Generally clothes should be close-fitting without restricting your freedom of movement.
Work is constantly in progress to improve the design and technology - improvements that increase your safety and efficiency. Visit your dealer regularly to see whether you can benefit from new features that have been introduced.
P ersonal protective equipment
IMPORTANT! Sparks can come from the muffler, the bar and chain or other sources. Always have fire extinguishing tools available if you should need them.
Help prevent forest fires.

′′′′s safety equipment
In this section the machine’s safety features and their function are explained. For inspection and maintenance see instructions under the heading Checking, maintaining and servicing chain saw safety equipment. See instructions under the heading, What is what?, to find where these parts are located on your machine.
The life span of the machine can be reduced and the risk of accidents can increase if machine maintenance is not carried out correctly and if service and/or repairs are not carried out professionally. If you need further information please contact your nearest servicing dealer.
!
WARNING! Most chain saw accidents happen when the chain touches the operator. You must use approved personal protective equipment whenever you use the machine. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your dealer for help in choosing the right equipment.
!
WARNING! Never use a machine with defective safety components. Safety equipment must be inspected and maintained. See instructions under the heading Checking, maintaining and servicing chain saw safety equipment. If your machine does not pass all the checks, take the saw to a servicing dealer for repair.
Chain brake and front hand guard
Your chain saw is equipped with a chain brake that is designed to stop the chain 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.
• Approved protective helmet
• Hearing protection
• Protective goggles or a visor
• Gloves with saw protection
• Trousers with saw protection

GENERAL SAFETY PRECAUTIONS
• The chain brake (A) can either be activated manually
(by your left hand) or automatically by the inertia release mechanism.
• The brake is applied when the front hand guard (B) is pushed forwards.
• To release the chain brake pull the front hand guard backwards, towards the front handle.
• This movement activates a spring-loaded mechanism that tightens the brake band (C) around the engine drive system (D) (clutch drum).
• 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.
• The front hand guard is not designed solely to activate the chain brake. Another important feature is that it reduces the risk of your left hand hitting the chain if you lose grip of the front handle.
• The way the chain brake is activated, either manually or automatically by the inertia release mechanism, 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 is designed to be activated by the inertia in the kickback direction.
• The chain brake must be engaged when the chain saw is started to prevent the saw chain from rotating.
• Use the chain brake as a ”parking brake” when starting and when moving over short distances, to reduce the risk of moving chain accidentally hitting your leg or anyone or anything close by.
If the kickback is less violent or the kickback zone of the bar is closer to you the chain brake is designed to be activated manually by the movement of your left hand.
• In the felling position the left hand is in a position that makes manual activation of the chain brake impossible. With this type of grip, that is when the left hand is placed so that it cannot affect the movement

GENERAL SAFETY PRECAUTIONS
of the front hand guard, the chain brake can only be activated by the inertia action.
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 grasp 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.
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 may 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 activate the chain brake; for example, when the saw chain is held in felling position.
Will my inetria activated chain brake always activate during kickback in the event of a kickback?
No. First your brake must be in working order. Testing the brake is simple, see instructions under the heading
Checking, maintaining and servicing chain saw safety equipment. We recommend you do before 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.
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 may be activated but 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.
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.
