D. DEBRANCHING AND PRUNING
• Work slowly, keeping both hands firmly
gripped on the saw. Maintain secure footing and
balance.
• Watch out for springpoles. Use extreme caution
when cutting small size limbs. Slender material
may catch the saw chain and be whipped toward you
or puli you off balance,
• Be alert for springback. Watch out for branches
that are bent or under pressure as you are cutting to
avoid being struck by the branch or the saw when
. the tension in the wood fibers^is released.
• Keep a clear work area? Frequently clear
branches out of the way to avoid tripping over them.
A WARNING
iiever climb into a tree to debranch or prune.
Do not stand on ladders, platforms, a log, or in
any position which can cause you to lose your
balance or control of the saw.
1. DEBRANCHING
a. Always debranch a tree after it is cut
down. Only then can debranching be done safe­
ly and properly.
b. Leave the larger limbs underneath the
felled tree to support the tree as you work.
c. Start at the base of the felled tree and
work toward the top, cutting branches and
limbs. Remove small umbs with one cut. Fig­
ure 27 .
d. Keep the tree between you and the chain.
Cut from the side of the tree opposite the branch
you are cutting.
e. Remove larger, supporting branches with
the 1/3,2/3 cutting techniques described in
the bucking section.
1. ) Undercut 1/3 of the way through the log.
2. ) Finish with an overcut.
f. Always use an overcut to cut small and
freely hanging limbs. Undercutting could
cause limbs to fail and pinch the saw.
2. PRUNING
a. Limit pruning to limbs shoulder height or
below. Do not cut if branches are higher than
your shoulder. Get a professional to do the job.
b. Refer to Figure 28 for the pruning tech­
nique.
1. ) Undercut 1/3 of the way through the limb
near the trunk of the tree.
2. ) Finish with an overcut farther out from the
trunk.
3. ) Keep out of the way of the falling limb.
4. ) Cut the stump flush near the trunk of the
tree.
A WARNING
Be alert for and guard against kickback. Do not
allow the moving chain to contact any other
branches or objects at the nose of the g|uide bar
when debranching or pruning. Allowing such
contact can result in serious ixyury.
