OPERATING INSTRUCTIONS
8. Felling A Tree Hazardous Conditions
WARNING
• When felling a tree, it is important that you
heed the following warnings to prevent possible
serious injury.
• Do not fell trees during periods of high wind or
heavy precipitation. Wait until the hazardous
weather has ended.
• Do not fell trees that lean at extreme angles
or large trees with rotten limbs, loose bark,
or hollow trunks. Instead, have these trees
pushed or dragged down with heavy equipment
and then cut them up.
• Do not fell trees near electrical wires or buildings.
• Check the tree for damaged or dead branches
that could fall and hit you during felling.
• Periodically glance at the top of the tree during
the back cut to assure the tree is going to fall in
the desired direction.
• If the tree starts to fall in the wrong direction, or
if the saw gets caught or hung up during the fall,
leave the saw and save yourself!
Preparation for Tree Felling
• 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 chainsaw operator should stand on the uphill side of the terrain, as the tree is likely to
roll or slide downhill after it is felled.
• Before any cuts are started, pick your escape route (or routes, in case the intended route
is blocked). Clear the immediate area around the tree and make sure that there are no
obstructions in your planned paths of retreat. Clear a path of safe retreat approximately 135°
from the planned line of fall. The retreat path should extend back and diagonally to the rear
of the expected line of fall. See Figure 8a.
• 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 through 1/3 the diameter of the tree, perpendicular to the direction of fall,
as illustrated in Fig. 8b. 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.
