WARNING!
Always be aware of the possibility of
kickbacks that can occur if the bar en-
counters an obstacle.
Kickback occurs when the tip of the chain
touches an obstacle, or when wood
blocks the chain whilst cutting. This con-
tact with the tip of the chain can cause
the bar to be violently jerked backwards
in the opposite direction, throwing it up
toward the user. This also happens when
the chain is jammed along the top of the
bar. In both cases, kickback can lead to
a loss of control of the chain saw and the
potentially serious consequences.
Before beginning with work, please read the
"For your safety" section. We recommend
practising on thinner tree trunks first. This will
help you become accustomed to working with
the chain saw.
Always follow the safety instructions. Only
use the chain saw to cut wood. It is prohibited
to cut other materials. In this case, the vibra-
tions and kickback would be different and the
safety requirements would not be complied
with. Do not use the chain saw as a lever to
lift, move or split objects and do not block it
on firm ground. It is prohibited to attach tools
or parts to the power take-off of the chain saw
that were not specified by the manufacturer.
It is not necessary to apply force while cut-
ting. After the engine has reached its maxi-
mum speed, apply light pressure only.
If the chain becomes jammed while cutting,
do not try to free it with force but use a wedge
or lever.
If there is an obstacle between the piece
being cut and the chain saw, switch off the
chain saw and wait for it to come to a stand-
still. Put on safety gloves and remove the
obstacle. If the chain needs to be removed,
follow the instructions in the section on instal-
ling the chain saw. After the obstacles has
been removed and the chain reinstalled, per-
form a test run. If vibrations or mechanical
noises are perceived during the test, stop
working and contact your dealer.

Using the bumper spike (if intended, Fig. 12)
1. Force the bumper spike into the trunk and use
the bumper spike as a fulcrum about which to
move the chain saw in an arc, thereby cutting
into the wood.
2. Repeat the working procedure several times,
moving the point of contact of the bumper
spike if necessary.
Pruning a tree (Fig. 13)
DANGER!
Make sure that the area where the bran-
ches will fall is clear.
When pruning trees at heights using a
rope and climbing harness, the instruc-
tion in the "For your safety" section must
be following closely.
WARNING!
Do not stand on unstable ground or
rung ladders when working.
Do not stretch out too far.
Do not cut higher than shoulder le-
vel.
1. Position yourself on the opposite side of the
branch to be cut off.
2. Start with the lowermost branches and then
move on to cutting the higher ones.
3. Cut from the top of the branch to the bottom
so as to prevent the bar from getting jammed.
Felling a tree (Fig. 14)
WARNING!
On slopes, always work on the uphill side
of the tree, and check that the felled tree
cannot cause any damage by rolling.
1. Select the felling direction of the tree by taking
account of the wind, angle of the tree, position
of the heaviest branches, simplicity of working
after felling, etc.
2. Clear the area around the tree and make sure
that you have a good standing position.
3. Make sure that suitable escape routes are
available without obstacles; the escape rou-
tes must be approximately 45° opposite to the
felling direction of the tree, and must make it
possible for the worker to escape to a safe
area at a distance that is about 2.5 times the
height of the tree to be felled.
