compression side of the log is where the

Limbing and Pruning
WARNING: Be alert for and guard against
F
kickback. Do not allow the moving chain
to contact any other branches or objects at
the nose of the guide bar when limbing or
D
pruning. Allowing such contact can result in
serious injury.
E
· Work slowly, keeping both hands on the saw
with a firm and proper grip. Maintain secure
NL
footing and balance.
· Keep the tree between you and the chain while
P
limbing. Cut from the side of the tree opposite
the branch you are cutting.
· Do not cut from a ladder, this is extremely

professionals.
TR
· Do not cut above chest height as a saw held
higher is difficult to control against kickback.
· Be alert for springback. Watch out for branches
CZ
that are bent or under pressure. Avoid being
struck by the branch or the saw when the
SK
tension in the wood fibers is released.
· Keep a clear work area. Frequently clear
branches out of the way to avoid tripping over

them.

WARNING: Only persons especially
trained in tree service operations are
PL
allowed to climb into a tree to limb or
prune. Do not stand on ladders, platforms,
a log or in any position which can cause you
H
to lose your balance or control of the saw.

Limbing Operation (Fig. 22)
· Always limb a tree after it is cut down. Only
then can limbing be done safely and properly.
EST
· Leave the larger limbs underneath the felled
tree to support the tree as you work.
LT
· Start at the base of the felled tree and work
toward the top, cutting branches and limbs.
Remove small limbs with one cut.
RO
· 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
20
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 Operation
· When pruning trees it is important not to make
the flush cut next to the main limb or trunk
until you have cut off the limb further out to
reduce the weight. This prevents stripping the
bark from the main member.
· Underbuck the branch 1/3 through for your
first cut, your second cut should overbuck to
drop the branch off.
· Now make your finishing cut smoothly and
neatly against the main member so the bark
will grow back to seal the wound.
WARNING: If the limbs to be pruned are
above chest height, hire a professional to
perform the pruning.
Springpoles
A springpole is any log, branch, rooted stump, or
sapling which is bent under tension by other
wood so that it springs back if the wood holding
it is cut or removed. On a fallen tree, a rooted
stump has a high potential of springing back to
the upright position during the bucking cut to
separate the log from the stump. Watch out for
springpoles. They are potentially dangerous.
WARNING: Springpoles are dangerous
and could strike the operator, causing
the operator to lose control of the chain saw.
This could result in severe or fatal injury to
the operator.

8. MAINTENANCE

Chain Maintenance
Use only Dual Raker low-kickback chain on this
saw. This fast-cutting chain will provide kickback
reduction when properly maintained.
For smooth and fast cutting, raker chain needs to
be maintained properly. The chain requires
sharpening when the wood chips are small and
powdery, the chain must be forced through the
wood during cutting, or the chain cuts to one
side. During maintenance of your chain, consider
