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.

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.

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.

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)

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).

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.

Your machine is equipped with a vibration damping system 
that is designed to reduce 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.

Use the stop switch to switch off the engine.

The muffler is designed to reduce noise levels and to direct 
exhaust fumes away from the user.

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 screen (A). (6)

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.

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.
