4. Vibration damp-
ing system
Your machine is equipped
with a vibration damping
system, which is designed to
give as vibration-free and
comfortable use as possible.
The machine's vibration
system reduces the transfer
of vibrations between the
engine unit and the harness.
The harness is also well
padded at the hip section
and has wide shoulder belts
to distribute the weight and
vibrations.
The vibrations you are
exposed to originate from
the "irregular" contact
which occurs between the
chain and the wood during
the sawing.
Sawing in "hard" wood
(most deciduous trees) gives
more vibrations than sawing
in "soft" wood (most
conifers).
Sawing with unsharp or
incorrect (wrong type or
incorrectly filed) cutting
equipment increases the
level of vibrations.
!
WARNING!
Over exposure to vibrations can result in
blood-vessel or nerve injury to persons
suffering with blood circulation problems.
Seek medical attention if you experience
physical symptoms that can be related to
over exposure to vibrations. Examples of
such symptoms are "numbness", lack of
feeling, "tickling", "pricking", "pain", lack
of or a reduction in normal strength,
changes in the colour of the skin or its
surfaces. These symptoms normally
appear in the fingers, hands or wrists.
SAFETY INSTRUCTIONS
5. Silencer
The silencer is designed to
give the lowest possible noise
level and to direct the
engine's exhaust fumes away
from the operator.
In countries that have a warm
and dry climate the risk of
fire is obvious. We have
therefore fitted certain
silencers with a spark arrest
screen. Check if your silencer
is fitted with this kind of
screen.
It is extremely important that the instructions for checking,
maintaining and servicing the silencer are followed. (See the
section "Control, maintenance and service of the machine's
safety equipment")
!
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!
!
WARNING!
During use and for some time after the
silencer is very hot. Do not touch the
silencer if it is hot!
6. Cutting equip-
ment
Observe care when using,
and make sure that the
blade's pitch sector never
comes into contact with
objects.
NOTE!
The guard should always be
fitted over the cutting
equipment during trans-
port and storage.
