CAUTION:
•
If the upper edge of the bar is used for cutting,
the chain saw may be deflected in your direction
if the chain becomes trapped. For this reason,
cut with the lower edge, so that the saw will be
deflected away from your body.
Cut wood under tension on the pressure side (A) first.
Then make the final cut on the tension side (B). This
prevents the bar from becoming trapped.
Limbing
CAUTION:
•
Limbing may only be performed by trained
persons. A hazard is presented by the risk of
kick-back.
When limbing, support the chain saw on the trunk if
possible. Do not cut with the tip of the bar, as this pres-
ents a risk of kickback.
Pay particular attention to branches under tension. Do
not cut unsupported branches from below.
Do not stand on the felled trunk when limbing.
Burrowing and parallel-to-grain cuts
CAUTION:
•
Burrowing and parallel-to-grain cuts may only
be carried out by persons with special training.
The possibility of kickback presents a risk of
injury.

Perform parallel-to-grain cuts at as shallow an angle as
possible. Carry out the cut as carefully as possible, as
the spike bumper cannot be used.
Felling
CAUTION:
•
Felling work may only be performed by trained
persons. The work is hazardous.
Observe local regulations if you wish to fell a tree.
► 1. Felling area
—
Before starting felling work, ensure that:
(1)
Only persons involved in the felling operation
are in the vicinity;
(2)
Any person involved has an unhindered path
of retreat through a range of approximately 45
° either side of the felling axis. Consider the
additional risk of tripping over electrical cables;
(3)
The base of the trunk is free of foreign
objects, roots and ranches;
(4)
No persons or objects are present over a
distance of 2 1/2 tree lengths in the direction
in which the tree will fall.
—
Consider the following with respect to each tree:
•
Direction of lean;
•
Loose or dry branches;
•
Height of the tree;
•
Natural overhang;
•
Whether or not the tree is rotten.
—
Consider the wind speed and direction. Do not
carry out felling work if the wind is gusting strongly.
—
Trimming of root swellings: Begin with the largest swell-
ings. Make the vertical cut first, then the horizontal cut.
