A good preventive maintenance program of regular inspection and care will increase life and improve performance of
your chain saw. This maintenance checklist is a guide for such a program.
Cleaning, adjustment, and part replacement may be required, under certain conditions, at more frequent intervals than
those indicated.

LIMBING
Limbing a tree is the process of removing the branches
from a fallen tree. Do not remove supporting limbs (A)
until after the log is bucked (cut) into lengths (Fig. 12).
Branches under tension should be cut from the bottom
up to avoid binding the chain saw.
BUCKING
Bucking is cutting a fallen log into lengths. Make sure
you have a good footing and stand uphill of the log when
cutting on sloping ground. If possible, the log should be
supported so that the end to be cut off is not resting on
the ground. If the log is supported at both ends and you
must cut in the middle, make a downward cut halfway
through the log and then make the undercut. This will
prevent the log from pinching the bar and chain. Be
careful that the chain does not cut into the ground when
bucking as this causes rapid dulling of the chain.

Fig. 13
Never cut tree limbs
while standing on a
tree trunk.
WARNING:
When bucking on a slope, always stand on the uphill side.
1. Log supported along entire length: Cut from top
(overbuck), being careful to avoid cutting into the
ground (Fig. 13).
2. Log supported on 1 end: First, cut from bottom
(underbuck) 1/3 diameter of log to avoid splintering.
Second, cut from above (overbuck) to meet first cut
and avoid pinching (Fig. 14).
3. Log supported on both ends: First, overbuck 1/3
diameter of log to avoid splintering. Second, underbuck
to meet first cut and avoid pinching (Fig. 15).
NOTE: The best way to hold a log while bucking is to use
a sawhorse. When this is not possible, the log
should be raised and supported by the limb
stumps or by using supporting logs. Be sure the
log being cut is securely supported.
BUCKING USING A SAWHORSE
For personal safety and ease of cutting, the correct
position for vertical bucking is essential (Fig. 16).
A. Hold the saw firmly with both hands and keep the
saw to the right of your body while cutting.
B. Keep the left arm as straight as possible.
C. Keep weight on both feet.

While the saw is
cutting, be sure the
chain and bar are being properly lubricated.
CAUTION:
