. ) Finish with an undercut.
5. BUCKING —USING A STAND (Figure 27):
a. InareaA;
1. ) Undercut 1 3 of the way through the log.
2. ) Finish with an overcut.
b. In area B:

. ) Over cut 1/3 ofthe way through the log.
2. ) Finish with an undercut.
A warning
Do not Stand on the log being cut. Any portion can roll
causing loss of footing and control.
O. DEBRANCHING AND PRUNING
• Work slowly, keeping both hands on the saw
with a firm grip. Maintain secure footing and bal­
ance.
• Watch out for springpotes. Use extreme caution
when cutting smalt size limbs. Slender material
may catch the saw chain and be whipped toward
you or pull 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 bran­
ches out of the way to avoid tripping over them.
A WARNING
Never climb into a tree to debranch or prune. Do
not stand on ladders, platforms, a log or in any posi­
tion which can cause you to lose your balance or
control of the saw.
1. OEBRANCHING
a. Always debranch a tree after it is cut down.
Only then can debranching be done safely
and properly.
b. Leave the larger lower limbs to support the
tree as you work.
c. Start at the base of the felled tree and work
towards the top, cutting branches and
limbs.
Remove small limbs with one cut. Fig­
ure 28.
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 ) Start with an undercut.
2.) Finish with an overcut.
f. Always use an overcut to cut small and
freely hanging limbs. Undercutting could
cause limbs to fall 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 29 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 failing 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 guide bar
when debranching or pruning. Allowing such con­
tact can result in serious injury.
