Overcutting Undercutting
Undercutting involves cutting on the un-
derside of the log with top of saw against
the log. When undercutting use light up-
ward pressure. Hold s aw firmly and main-
tain control. The saw w ill tend to push
back toward you.

down to undercut. The saw cannot be
controlled in this position.
Always make your first cut on the com-
pressions side of the log. The compres-

LIMBING AND PRUNING
WARNING:
Be alert for and guard
against kickback. Do not allow the mov-

or objects at the nose of the guide bar
when limbing or pruning. Allowing such

ders, platforms, a log, or in any position

branches that are bent or under pres-

or the saw when the tension in the w ood
fibers is released.
S
Frequently clear branches out of the
way to avoid tripping over them.

Limb a tree only after it is cut down.
S
Leave the larger limbs underneath the
felled tree to support the tree as you

Start at the base of the felled tree and
work toward the top, cutting branches
and limbs. Remove sm all limbs with one
cut.

Keep tree between you and the chain.
