- If the guide bar and the chain are stuck in the wood during the cutting operation, proceed as
follows:
1)
with the engine off, tie the chain saw to the tree (towards the trunk) by using an
additional, separate rope;
2)
remove the chain saw from the cut by moving and lifting the branch;
3)
if necessary, use a hand saw or a second petrol chain saw by making a cut at least
30cm (from the stuck chain saw) towards the end of the branch in order to stop the
branch from falling with the chain saw and therefore to cause additional problems.
WARNING
Using a mechanical basket (where possible) is still the safest solution to ensure the optimal
operation of the chain saw (see fig.18).
Additional instructions for the use of land to chainsaw
The operation of tree felling requires professionally trained and qualified personnel.
Reading of these instructions is always necessary, but is not a substitute for adequate expe-
rience in performing this delicate operation.
- Before felling. Ensure that:
1)
There are no other people or animals within the range of the fallen tree.
2)
Select the direction in which the tree is to fall in such a way that you can move away in
the opposite direction (fig.38).
3)
Check that the escape rout is free of obstacles.
4)
Select the direction of fall taking account of the following variables.
Branches weighted towards one side.
-
Slant of the tree.
-
Direction of the wind (do not fell when the wind is strong)
-
-
Damaged wood
5)
Carefully observe the environmental conditions described in "GENERAL SAFETY
REGULATIONS POINT A6".
6)
Free the base of the trunk, cutting branches and big roots.
7)
To decide the direction of fall:
Cut a notch (fig.40) on the side of the trunk towards which you want it to fall.
-
Penetrate to about 1/3 of the trunk diameter.
Make the felling cut from the opposite side from the notch (fig.41) about 5 cm higher
-
up.
-
ATTENTION ! Do not complete the cut but leave enough wood to act as a hinge
when the tree falls, controlling the direction of fall (fig.41 part.1).
Use a wedge to start the fall (fig.42).
-
As soon as the tree starts to fall, move away in the direction decided on previously
-
(fig.38).
Cutting of branches and the trunk on the ground
Trunk resting on its ends:
1)
Make a cut from above to 1/3 of the diameter (fig.43).
