REMOVING A PINCHED SAW
(A SAW HUNG IN THE LOG)
S If saw becomes pinched or hung in a log,
don’t try to force it out. You can lose con-
trol of the saw resulting in personal injury
and/or damage to the saw. Stop the saw
and drive plastic or wooden wedge into
the cut until saw can be removed easily.
S Restart the saw and carefully reenter the
cut. To avoid kickback and chain dam-
age, do not use a metal wedge. Do not at-
tempt to restart your saw when it is
pinched or hung in a log.

Turn saw OFF and use a plastic or
wooden wedge to force cut open.
LIMBING AND PRUNING
WARNING : Never climb into a tree to
limb or prune. Do not stand on ladders, plat-
forms, a log, or in any position which can
cause you to lose your balance or control of
the saw.
IMPORTANT POINTS
S Work slowly, keeping both hands firmly
gripped on the saw. Maintain secure foot-
ing and balance.
S Watch out for springpoles. Use extreme
caution when cutting small limbs. Slender
material may catch saw chain and be
whipped toward you or pull you off bal-
ance.
S Be alert for springback. Watch out for
branches that are bent or under pressure.
Avoid being struck by the branch or saw
when tension in wood fibers is released.
S Keep a clear work area. Frequently clear
branches out of the way to avoid tripping
over them.
LIMBING
S Always limb a tree after it is cut down.
Only then can limbing be done safely and
properly.
S
Leave the larger limbs underneath the
felled tree to support the tree as you work.
S
Start at the base of felled tree and work to-
ward the top, cutting branches and limbs.
Remove small limbs with one cut.
S
Keep the tree between you and the chain.
Cut from the side of the tree opposite the
branch you are cutting.
S Remove larger, supporting branches with
the 1/3 , 2/3 cutting techniques described
in the bucking section.
S
Undercut 1/3 of the way through log.
S Finish with an overcut.
S Always use an overcut to cut small and
freely hanging limbs. Undercutting could
cause limbs to fall and pinch the saw.
PRUNING
WARNING : Be alert for and guard
against kickback. Do not allow the moving
chain to contact any other branches or ob-
jects at the nose of the guide bar when limb-
ing or pruning. Allowing such contact can
result in serious injury.
S 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.
S See illustration for the pruning
technique.
S Make your fist cut 1/3 of the way
through the bottom of the limb.
S Next make a 2nd cut all the way
through the limb. Then cut a third
overcut leaving a 1 to 2 inch collar
from the truck of the tree.
