Undercutti_',_s
Undercutting
involves
cutting on the
underside
of the log with top of saw
against the log. When undercutting
use light upward pressure.
Hold saw
firmly and maintain control. The saw
will tend to push back toward you.
WARNING:
Never turn saw up-
side down to undercut.
The saw can-
not be controlled
in this position.
Always make your first cut on the com-
pression
side of the log. The compres-
sion side of the log is where the pres-
sure of the log's weight is
concentrated.

BUCKING WITHOUT
A SUPPORT
• Overcut through
1/3 of the diameter
of the log.
• Roll the log over and finish with a
second overcut.
• Watch for logs with a compression
side to prevent the saw from pinch-
ing.
See illustration
above for cut-
ting logs with a compression
side.

WARNING:
Be alert for and guard
against
kickback.
Do not allow the mov-
ing chain to contact
any other branches
or objects at the nose of the guide bar
when limbing or pruning.
Allowing such
contact can result in serious injury.
WARNING:
Never climb into a
tree to limb or prune. Do not stand on
ladders, platforms, a log, or in any po-
sition which can cause you to lose
your balance
or control of the saw.
IMPORTANT
POINTS
• Watch out for springpoles.
Springpoles
are small size limbs
which can whip toward you, or pull
you off balance.
Use extreme
cau-
tion when cutting small size limbs.
• Be alert for springback
from any
branches that are bent or under
pressure. Avoid being struck by the
branch or the saw when the tension
in the wood fibers is released.
• Frequently
clear branches out of the
way to avoid tripping over them.
LIMBING
• Limb a tree only after it is cut down.
• Leave the larger limbs underneath
the felled tree to support the tree as
you work.
• Start at the base of the felled tree
and work toward the top, cutting
branches and limbs. Remove small
limbs with one cut.
