PRUNING
See Figure 23.
Pruning is trimming limbs from a live tree.
■ Work slowly, keeping both hands on the chain saw
with a firm grip. Always make sure your footing is
secure and your weight is distributed evenly on
both feet.
■ Do not cut from a ladder, this is extremely danger-
ous. Leave this operation for professionals.
■ Do not cut above chest height as a saw held higher
is difficult to control against kickback.
■ When pruning trees it is important not to make the
finishing cut next to the main limb or trunk until you
have cut off the limb further out to reduce the
weight. This prevents stripping the bark from the
main member.
1. Underbuck the branch 1/3 through for your first
cut.
2. Your second cut should overbuck to drop the
branch off.
3. Now make your finishing cut smoothly and
neatly against the main member so the bark will
grow back to seal the wound.
FINISHING CUT
WARNING:
If the limbs to be pruned are above chest height,
hire a professional to perform the pruning.

SPRINGPOLES
See Figure 24.
A springpole is any log, branch, rooted stump, or
sapling which is bent under tension by other wood so
that it springs back if the wood holding it is cut or
removed. On a fallen tree, a rooted stump has a high
potential of springing back to the upright position
during the bucking cut to separate the log from the
stump. Watch out for springpoles, they are dangerous.
WARNING:
Springpoles are dangerous and could strike the
operator, causing the operator to lose control of
the chain saw. This could result in severe or
fatal injury to the operator.
