Felling back cut
Make the felling back cut at least 2 inches (50.8 mm) higher
than the horizontal notching cut as shown in Fig. B. Keep the
felling back cut parallel to the horizontal notching cut. Make
the felling back cut so enough wood is teft to act as a hinge.
The hinge wood keeps the tree from twisting and falling in the
wrong direction. Do not cut through the hinge.
As the felling cut gets close to the hinge the tree should begin
to fall. If there is any chance that the tree may not fall in the
desired direction or it may rock back and bind the saw chain,
stop cutting before the felling back cut is complete and use
wedges of wood, plastic or aluminum to open the cut and drop
the tree along the desired line of fall. When the tree begins to
fall remove the chain saw from the cut, stop the motor, put the
chain saw down, then use the retreat path planned. Be alert
for overhead limbs falling and watch your footing.
Limbing a tree
Limbing is removing the branches from a fallen tree. When
limbing, leave larger lower limbs to support the log off the
ground. Remove the small limbs in one cut as shown in Fig.
C. Branches under tension should be cut from the bottom up
to avoid binding the chain saw.
Bucking a log
Bucking is cutting a log into lengths. It is important to make
sure your footing is firm and your weight is evenly distributed
on both feet. When possible, the log shoutd be raised and
supported by the use of limbs, logs or chocks. Follow the sim-
ple directions for easy cutting.
When the log is supported along its entire Iength as shown in
Fig. D, it is cut from the top (overbuck).
When the log is supported on one end, as shown in Fig. E,
cut 1/3 the diameter from the underside (underbuck ). Then
make the finished cut by overbucking to meet the first cut.
When the log is supported on both ends, as shown in Fig. F,
cut 1/3 of that diameter from the top overbuck. Then make the
finished cut by underbucking the lower 2/3 to meet the first
cut.
When bucking on a slope, always stand on the uphill side of
the log, as shown in Fig. G. When "cutting through", to maintain
complete control, release the cutting pressure near the end
of the cut without relaxing your grip on the chain saw handles.
Don't let the chain contact the ground. After completing the
cut, wait for the saw chain to stop before you move the chain
saw. Always stop the motor before moving from tree to tree.
Carrying tool
Carry the tool by the front handle with the tool turned off,
finger off the switch. Use the chain protection cover to cover
the guide bar and the saw chain.
LIMB CUT
Keep work off ground
Leave support limbs until log is cut
C
Cut from top (overbuck)
avoid cutting earth
D
2nd cut overbuck (2/3 diameter)
to meet 1st cut (to avoid pinching)
Tension side
Pressure side
1st cut underbuck (1/3 diameter)
to avoid splintering
E
1st cut overbuck (1/3 diameter)
to avoid splintering
2nd cut underbuck (2/3 diameter)
to meet 1st cut (to avoid pinching)
F
G
Pressure side
Tension side
Stand on uphill side when
cutting because log may roll.
