Using The Chain Saw; Felling A Tree; Notching Undercut - Makita 5014NB Instruction Manual

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,
a t
the
same time, the felling operation should be separated from the bucking operation by
a
distance of a t 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 i s 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 i s being made.
