Maintenance and care

7.3

Delimbing (16)

Heed the following points during this work:
■
Brace the chain saw against the tree trunk
and sequentially cut off the freely accessible
branches on the tree trunk, one after the oth-
er (16/a). When working on a slope, carry out
preparatory work from below to above.
■
Leave larger, downward-pointing branches
supporting the tree standing at first.
■
Cut off smaller branches with one cut.
■
Pay attention to branches under tension, and
first saw through them a little from above,
then from underneath upwards, in order to
prevent the chain saw becoming trapped (16/
b).
■
First saw free-hanging branches a little from
below, then saw entirely through them from
above downward (16/c).
■
Only experienced or trained people should
make plunge cuts, longitudinal cuts and bor-
ing cuts.
7.4

Cross-cutting (17, 18, 19)

Heed the following points during this work:
■
When working on a slope, always stand uphill
from the tree trunk, because it could roll
away.
■
Guide the chain saw so that there is no part
of your body in the extended sweep arc of
the saw chain.
■
Positioning the chain on the trunk:
■
Position the bumper spike directly adja-
cent to the cut edge and allow the chain
saw to pivot about this point.
■
The chain saw can slip sideways or jump
easily when it is positioned. This depends
on the wood and the condition of the saw
chain. For this reason, always hold the
chain saw firmly.
■
At the end of the cut, the chain saw swings
due to its own weight because it is no longer
supported in the cut. Counteract this in a con-
trolled way and do not apply pressure so the
saw chain does not touch the ground.
■
After finishing the cut, wait for the saw chain
to come to a halt before you switch off the
chain saw.
■
Always switch off the motor of the chain saw
before you go to the next tree.

The entire length of the tree trunk is in contact
with the ground:
■
Saw through the tree trunk from above, with-
out cutting into the ground (17/a).
Tree trunk is lying raised at one end:
■
To prevent the chain saw becoming trapped
and the wood splintering, first saw through
1/3 of the trunk diameter from below (18/a),
then saw through the remainder from above,
parallel to the cut made from below (18/b).
Tree trunk is lying raised at both ends:
To prevent the chain saw becoming trapped and
the wood splintering, first saw through 1/3 of the
trunk diameter from above (19/a), then saw
through the remainder from below, parallel to the
cut made from above (19/b).

Cutting converted timber

Heed the following points during this work:
■
Use a secure cutting surface (sawing trestle,
wedges, beams).
■
Make sure you are standing securely and
that your bodyweight is evenly distributed.
■
Secure logs to prevent them twisting.
■
Only start the cut once the saw chain is run-
ning. Never switch on the chain saw already
in the kerf.
■
Do not secure the wood with your foot and do
not get another person to hold it.
