ENGLISH
When supported along its whole length:
Make a downward cut, but avoid cutting the earth as this
u
will blunt your saw chain quickly.
When supported at both ends:
First, cut one third down to avoid splintering and second,
u
cut up to meet the first cut.
When supported at one end:
First cut one third up to avoid splintering and second, cut
u
down to prevent splintering.
When on a slope:
Always stand on the uphill side.
u
When attempting to cut a log on the ground (fig. M):
Secure the workpiece using chocks or wedges. The user
u
or a bystander should not steady the log by sitting or
standing on it. Make sure that the saw chain does not
contact the ground.
When using a saw horse (fig. N):
This is strongly recommended whenever possible.
Position the log in a stable position. Always cut on the
u
outside of the saw horse arms. Use clamps or straps to
secure the workpiece.
Limbing (fig. O)
Removing the branches from a fallen tree. When limbing,
leave larger lower limbs to support the log off the ground.
Remove the small limbs in one cut. Branches under tension
should be cut from the bottom of the branch towards the top to
avoid binding the chain saw.
Trim limbs from opposite side keeping tree stem between you
and saw. Never make cuts with saw between your legs or
straddle the limb to be cut.
