AWARNING
Do not stand on the log being cut. Any portion can roll causing loss of footing and control.

2,) Finish with an overcut,
b.In areaB:
1_) Overcut, 1/3 of the way through the tog, 2,) Finish with an undercut.

D. DEBRANCHING AND PRUNING
•Work slowly, keeping both hands on the saw with a firm grip. Maintain secure footing and bal- ance.
•Watch out for springpoles. Use extreme caution when cutting small size limbs, Slender material can catch the saw chain and be whippedtoward 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 isreleased.
•Keep a clear work area. Frequently,clear branches out ofthe way to avoidtripping over them.
WARNING
Never 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 thencan debranching be done safely and properly.
b. Leave the larger lower limbs to support the
tree as you work.
cStart at the base of the felled tree and work towards the top, cutting branches and limbs. Remove small limbs with one cut. Figure 25.
d.Keep the tree between you and the chain. Cut from the side of the tree opposite the branch you are cutting
eRemove larger, supporting branches with the t/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. Undercuttingcancause limbs to fall and pinch the saw.
b.In area B:
1,) Over cut 1/3 of the way through the log. 2.) Finish with an undercut.
USE COMMON SENSE | MAINTAIN SECURE FOOTING |
. PRUNING
a, Limit pruning to limbs shoulder height or
below. Do not cut if branches are higher than your shoulder. Get a professional lo do the job.
b.Refer to Figure 26 for the pruning technique.
1.) Undercut ! 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 hmb.
4.) Cut the stump flush near the trunk of the tree.
_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 contact can result in serious injury,
