Limbing and pruning
a
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 limbing or
pruning. Allowing such contact can result in
serious injury.
a
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.
Important points:
• Work slowly, keeping both hands firmly gripped on
the saw. Maintain secure footing and balance.
•
Watch out for springpoles. Springpoles are small
size limbs which can catch the saw chain and
whip toward you or pull you off balance. Use
extreme caution when cutting small size limbs or
slender material.
•
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.
•
Keep a clear work area. Frequently clear
branches out of the way to avoid tripping over
them.
Limbing
Always limb a tree after it is cut down. Only then can
limbing be done safely and properly.
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.
Keep the tree between you and the chain. Cut from
the side of the tree opposite the branch you are
cutting.
Remove larger, supporting branches with the cutting
techniques described in BUCKING WITHOUT A
SUPPORT.
Always use an overcut to cut small and freely hanging
limbs. Undercutting could cause limbs to fall and pinch
the saw.
Pruning
a
WARNING! 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.
1.
Make the first cut one-third of the way through the
bottom of the limb.
2. Make the second cut all the way through the limb.
3. Make the third overcut leaving a 2.5 to 5
centimeter (1 to 2 inch) collar from the trunk of the
tree.
