with the motor running. use wedges to
free chain and chain bar.
When any other cutting operation and a
felling operation are being performed by
two or more persons at the same time, the
felling operation should be separated from
the cutting 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.
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.
Escape Route: An escape path should be
planned and cleared as necessary before any
cuts are started. Make sure to remove any low
hanging limbs up to shoulder height, as well
as all undergrowth around the base of the
tree that may prove to be an obstacle during
escape. Your escape paths should be roughly
135 degrees away from the intended felling
direction.
direction of Fall: 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.
Felling is a process of three cuts. First
you make your notch cuts, which
consist of a top and bottom cut. Finally,
you will make the felling cut.
Notching undercut: Make the notch (x-w)1/3
the diameter of the tree. The notch is cut on
the side of the tree in the desired direction of
the fall. Make the lower horizontal notching
cut first as this will help to avoid pinching
either the saw chain or the guide bar when
the second notch cut is being made.
waRNiNg: do not make the felling
back cut all the way through tree.
leave about two inches of tree diameter
uncut directly behind felling notch (See
Fig. m1, m2). this uncut portion acts
as a hinge(y). the hinge helps keep
tree from twisting and falling in wrong
direction.
Electric Chain Saw
After removing the wood from the notch
make the felling back cut on the opposite side
of the notch. This is done by making a cut
about two inches higher than the center of
the notch. This will leave enough uncut wood
between the felling cut and the notch to form
a hinge. This hinge will help prevent the tree
from falling in the wrong direction. Hinge
holds the tree on stump and helps control fall
(See Fig. M1).
As the felling back cut 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 cut before the felling back
cut is complete and use wedges (Z) of wood,
plastic, or aluminum 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, and then use the retreat path
planned. Be alert for overhead limbs falling
and watch your footing.
To complete the felling operation, drive a
wedge (Z) into the horizontal felling cut (See
Fig. M2).
limbiNg a tREE (See Fig. N)
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.
buCkiNg a lOg (See Fig. O)
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 possible, the log should be
raised and supported by limbs, logs or chocks.
Follow the simple directions for easy cutting.
When the log is supported along its entirety,
laying flat along the ground as illustrated, it is
cut from the top (overbuck) (See Fig. O).
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
