GENERAL SAFETY PRECAUTIONS

Will my inertia 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.

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. (5)

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′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine′s handle unit. The body of the chain saw, including the cutting equipment, is insulated from the handles by vibration damping units.

Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers). Cutting

with cutting equipment that is blunt or faulty (wrong type or badly sharpened) will increase the vibration level.

!	WARNING! 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. 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.

Muffler

The muffler is designed to reduce noise levels 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 government rules requiring among other things the muffler must be equipped with an approved type of spark arrestor mesh (A). (6)

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.
