WORKING WITH THE CHAIN SAW
Bucking
006913
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 rear 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.
006914
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
006915
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
006916
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 serrated rail cannot be used.
Felling
CAUTION:
• Felling work may only be performed by trained persons. The work is
hazardous.
