WARNING:
Before making the final cut, always
recheck the area for bystanders, animals or
obstacles.
FELLING CUT:
1. Use wooden or plastic wedges (A) to prevent
binding the bar or chain (B) in the cut. Wedges
also control felling (Fig. 14A).
2. When diameter of wood being cut is greater than
the bar length, make 2 cuts as shown (Fig. 14B).
WARNING
: As the felling cut gets close to the
hinge, the tree should begin to fall. When tree begins
to fall, remove saw from cut, stop engine, put chain
saw down, and leave area along retreat path (Fig.
12).
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. 15). Branches under tension should
be cut from the bottom up to avoid binding the chain
saw.
WARNING
: Never cut tree limbs while standing on
tree trunk.
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.
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. 16A).
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. 16B).
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. 16C).
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. 17).
VERTICAL CUTTING:
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.
CAUTION:
When working with the saw, always
make sure that the saw chain and chain bar are
sufficiently lubricated.
