Using the chain saw
Always be sure of your footing and hold the chain
saw
firmly
with
both
hands
while
the
motor
is
running.
Felling
a
tree
When bucking and felling operations are being performed by
two
or more persons,
at
the
same time, the felling operation should be separated from the bucking operation by
a
distance of
at
least
twice
the height of the tree being felled. Trees should not be felled in
a
manner that would endanger any person, strike any utility line
or
cause any property
damage. If the tree does make contact with any utility line, the utility company should
be notified immediately.
The chain saw operator should keep on the uphill side of the terrain
as
the tree
is
likely
to roll or slide downhill after
it
is
felled.
A
retreat path should be planned and
cleared
as
necessary before cuts are started.
The retreat path should extend back and
diagonally to the rear of the expected line
of fall
as
shown in
Fig.
16.

Before felling
is
started, consider the natural lean of the tree, the location
of
larger
branches and the wind direction to judge which way the tree will fall. Remove dirt, stones,
loose bark, nails, staples, and wire from the tree where felling cuts are to be made.
Notching undercut
Make the notch
1/3
the diameter of the tree, perpendicular to the direction of fall
as
shown in Fig.
17.
Make the lower horizontal notching cut first. This will help to avoid
pinching of either the saw chain or the guide bar when the second notch
is
being made.
