2.
With the saw chain running, saw into the wood while using
the rear handle to raise the saw and the front one to guide it. Use
the spike bumper as a pivot.
3.
Continue the cut by applying slight pressure to the front
handle, easing the saw back slightly. Move the spike bumper
further down the timber and raise the front handle again.
NOTICE: When making several cuts, switch the chain saw off
between cuts.
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.
When you cut a wood under tension, cut the pressured side (B)
first. Then make the final cut from the tensioned side (A). 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 kickback.
When limbing, support the chain saw on the trunk if possible. Do
not cut with the tip of the bar, as this presents 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. Take an
extra caution when carrying out the cut 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. Before starting felling work, ensure that:
Only persons involved in the felling operation are in the vicinity;
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;
The base of the trunk is free of foreign objects, roots and ranches;
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 swellings. Make the vertical cut first, then
the horizontal cut.
— Stand to the side of the falling tree. Keep an area clear to the
rear of the falling tree up to an angle of 45° either side of the tree
axis (refer to the “felling area” figure). Pay attention to falling
branches.— An escape path should be planned and cleared as
necessary before cuts are started. The escape path should extend
back and diagonally to the rear of the expected line of fall as
illustrated in figure.
