GENERAL SAFETY PRECAUTIONS
Before using a new chain saw please read this manual
carefully.
WARNING! Under no circumstances may the
design of the machine be modied without
the permission of the manufacturer. Always
use genuine accessories. Non-authorized modica-
tions and/or accessories can result in serious personal
injury or the death of the operator or others.
WARNING! A chain saw is a dangerous tool if
used carelessly or incorrectly and can cause
serious, even fatal injuries. It is very impor-
tant that you read and understand the contents of this
operator’s manual.
WARNING!Runninganengineinaconned
or badly ventilated area can result in death
due to asphyxiation or carbon monoxide poi-
soning.
PERSONAL PROTECTIVE 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
Generally clothes should be close-tting without re-
stricting your freedom of movement.
MACHINE'S SAFETY EQUIPMENT
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 service work-
shop.
WARNING! Never use a machine with defec-
tive safety components. Safety equipment
must be inspected and
maintained. See instructions under the heading Check-
ing, maintaining and servicing chain saw safety equip-
ment. 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 can either be activated manually
(by your left hand) or automatically by the inertia re-
lease mechanism.
● The brakeis appliedwhenthefronthand guardis
pushed forwards.
● This movement activates a spring-loaded mecha-
nism that tightens the brake band around the engine
drive system (clutch drum).
● The fronthand guardisnotdesignedsolely toac-
tivate 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 rotat-
ing.
● 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rmlyandnotletgo.
● Thewaythechainbrakeisactivated,eithermanu-
ally or automatically by the inertia release mecha-
nism, 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.
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 insu-
lated 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 vi-
bration level.
