Always use common sense (2)
It is not possible 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. 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.
Personal protective equipment
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.
• Approved protective helmet
• Hearing protection
• Protective goggles or a visor
• Gloves with saw protection
• Trousers with saw protection
• 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.
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.
Machine' ' ' ' 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

GENERAL SAFETY PRECAUTIONS
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! 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.
• The chain brake (A) can either be activated manually
(by your left hand) or automatically by the inertia
release mechanism. (3)
• The brake is applied when the front hand guard (B) is
pushed forwards. (3)
• This movement activates a spring-loaded
mechanism that tightens the brake band (C) around
the engine drive system (D) (clutch drum). (4)
• 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 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.
• To release the chain brake pull the front hand guard
backwards, towards the front handle.
• 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 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.
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
of the front hand guard, the chain brake can only be
activated by the inertia action.
