4. Pre-tighten the chain (5) by
turning the tensioning plate (22)
clockwise.
5. Position the sprocket chain
wheel covering (15). First place
the tab (24) on the cover into the
corresponding notch on the plate
(15). Only lightly tighten the fas-
tening bolt (14), as you will still
have to tension the saw.
Refer to the start-up section on
how to tension the saw chain.

Sawing techniques

General

• You have better control when you saw
with the bottom side of the chain bar
(with pulling saw chain) and not to
with the top side of the chain bar (with
pushing saw chain).
• The saw chain must not contact either
the ground or another object during
sawing through or after sawing com-
pletion.
• Make sure that the saw chain does
not become jammed in the wood. Do
not let the tree trunk break or split off.
• Consider also the precautions against
spring-back (see notes on safety).
• When removing branches, leave
larger, downward facing limbs that are
supporting the tree at their place for
the moment. Remove smaller branch-
es with a single cut (see
If the saw chain jams, you
do not attempt to pull out the
electric chainsaw using power.
There is a danger of injury here.
Switch off the motor and use a
lever or wedge to free the elec-
tric chainsaw.

This refers to sawing up a felled tree trunk
into smaller sections.
Ensure that you are in a secure position
and that your body weight is distributed
evenly on both feet. If possible, under-
pin and support the stem with branches,
beams or wedges.

Ensure that the saw chain does not
come in contact with the ground dur-
ing sawing.
Make sure you have a secure stance
and, in the case of sloping ground,
stand above the log.
To maintain full control at the mo-
ment of "sawing through", reduce the
contact pressure at the end of the
cut, without releasing the firm grip on
the chain saw handles. Once cutting
is complete, wait for the saw chain
to come to a standstill before remov-
ing the chain saw from there. Always
switch off the chain saw before chang-
ing from tree to tree.
1. Log is lying on the ground:
Saw through the log completely
from above and ensure at the
end of the cut not to contact the
ground.
If you can turn the tree trunk,
saw two-thirds of the way
through it. Then turn the trunk
around and saw the rest of the
way through from above.
2. Log is supported at one end:
Start sawing from the bottom
and work your way up (with the
upper edge of the bar) a third of
the way into the diameter of the
trunk to prevent splitting. Then
saw from the top downwards
