LIMBING AND PRUNING
WARNING:
Never climb into a tree to limb
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.
I MPORTANT POINTS
S Watch out for springpoles. Use extreme
caution when cutting small size limbs. Slen-
der material may catch saw chain and be
whipped toward you or pull you off balance.
S Be alert for springback. Watch out for
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.
S 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 base of the 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
as much as possible.
S
Remove larger, supporting branches with
the 1/3 , 2/3 cutting techniques described
in the bucking section.
S
Always use an overcut to cut small and
freely hanging limbs. Undercutting could
cause limbs to fall and pinch saw.
PRUNING
WARNING: Limit pruning to limbs shoul-
der height or below. Do not cut if branches
are higher than your shoulder. Get a profes-
sional to do the job.
S
Make your first 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 trunk of the
tree.
