Vibration damping system
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
vibr
ation than cutting softw
oods (most conifers). Cutting
with cutting equipment that is blunt or faulty (wrong type
or badly sharpened) will increase the vibration level.
Stop switch
Use the stop switch to switch off the engine.
Muffler
The muffler is designed to keep noise levels to a minimum
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 go
v
ernment rules
requiring among other things the muffler must be
equipped with an approved type of 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.
General rules
Only use cutting equipment recommended by us!
See instructions under the heading Technical data.
Keep the chain’s cutting teeth properly
sharpened! Follow our instructions and use the
recommended file gauge.
A damaged or badly
sharpened chain increases the risk of accidents.
Maintain the correct depth gauge setting! Follow
our instructions and use the recommended depth
gauge clearance.
Too large a clearance increases
the risk of kickback.
!
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.
!
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!
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.
