If you try to cut off thick branches from the top without a
shallow undercut, the branch may splinter.

If you cannot cut the timber right through with a single
stroke:
Apply light pressure to the handle and continue sawing
and draw the chain saw back a little; then apply the spike
a little lower and finish the cut by raising the handle.
Bucking
010941
For bucking cuts, rest the serrated rail shown in the figure
on the wood to be cut.
With the saw chain running, saw into the wood, using the
top handle to raise the saw and the front one to guide it.
Use the serrated rail as a pivot.
Continue the cut by applying slight pressure to the front
handle, easing the saw back slightly. Move the serrated
rail further down the timber and raise the front handle
again.
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.

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
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.
010942
Perform parallel-to-grain cuts at as shallow an angle as
possible. Carry out the cut as carefully as possible, as
the serrated rail 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.
