For bucking cuts, rest the spike bumper shown in the
figure on the wood to be cut.
With the saw chain running, saw into the wood, using
the rear handle to raise the saw and the front one to
guide it. Use the spike bumper as a pivot.
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.
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.
006914
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.
014390
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.
