Limbing A Tree - Makita GCU04 Instruction Manual

As the felling gets close to the hinge, the tree should
begin to fall. If there is any chance that the tree may
not fall in 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 aluminium
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

CAUTION:
Limbing may only be performed by
trained persons. A hazard is presented by the risk
of kickback.
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
illustrated. Branches under tension should be cut from
the bottom up to avoid binding the chain saw.

Cross-cutting/bucking a log
Cross-cutting/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 possi-
ble, the log should be raised and supported by the use
of limbs, logs or chocks. Follow the simple directions for
easy cutting.
When the log is supported along its entire length as
illustrated, it is cut from the top (overbuck).
Fig.25
When the log is supported on one end, as illustrated,
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 illustrated,
cut 1/3 the diameter from the top (overbuck). Then
make the finished cut by underbucking the lower 2/3 to
meet the first cut.

When cross-cutting/bucking on a slope always stand on
the uphill side of the log, as illustrated. 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.
