1. When bucking and felling operations are being performed by two
or more persons at the same time, the felling operations 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 company
should be notified immediately.
2. The product operator should keep on
the uphill side of the terrain as the tree
is likely to roll or slide downhill after it is
felled.
3. An escape path should be planned and
cleared as necessary before cuts are
started. The escape path should extend
back and diagonally to the rear of the
expected line of fall (Fig. 28).
• Always use a low kickback chain.
• Apply the metal gripping teeth for leverage.
• Ensure correct chain tension.
4. 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.
5. Remove dirt, stones, loose bark, nails, staples and wire from the
tree.
Notching undercut
Makethe notch (Fig. 29, B) 1/3 the diameter of the tree,
perpendicular to the direction of falls (Fig. 29). Make the lower
horizontal notching cut first. This will help to avoid pinching either the
saw chain or the guide bar when the second notch is being made.
