FELLING OR BACK CUT
4. The felling or back cut is made on the side opposite
and at least 2 inches above the hori zontal undercut
(the felling cut is made higher as the size of the tree
increases). Place the saw so the hand guard is close
to the tree trunk and the bucking cleat is dug in.
5. Start the cut horizontally. Pivot the bar in until the cut
is being made parallel to the notch cut. Cut until the
saw is about 1 or 2 inches from the notch. Do not cut
through the notch.
NOTE:
The uncut wood between the felling and notch cuts
is called the hinge. The hinge controls the fall of the
tree and should be of uniform thick ness.
6. As the saw nears the back cut, watch the treetop
and the cut for signs of movement. Be alert as soon
as the tree starts to move, turn off the saw, pull it
from the tree and move away quickly on your es-
cape route.
7. For trees larger than bar length, make two felling
cuts. Cut in as far as the bar will go, move to the
other side and start the second cut in the same man-
ner as the rst while pivoting the saw to complete
the felling cut.
BUCKING
Bucking is the sawing of a log or fallen tree into smaller
pieces.
1. Observe all safety precautions.
2. Use both hands. Grip the saw rmly.
3. Stand uphill. A log that is cut loose may role down-
hill.
4. Keep the chain out of the dirt. Dirt will dull the chain.
A dull chain is unsafe.
5. Stand to the left of the saw.
CROSSCUTTING
NOTE:
Before starting to cut through a log try to imagine
what is going to happen. Look out for stresses in the
log and cut through the log in such a manner that
the guide bar will not get pinched.
6. The saw chain should cut with very little pres sure
applied to the handle. If you have to force the saw to
cut or if the cut is not straight, cease cutting immedi-
ately to prevent further saw chain and bar damage.
See the Maintenance and Adjustments section of
the Service Manual for chain replacement or adjust-
ment procedures.
7. Underwater models require daily preventive mainte-
nance. See the Maintenance and Adjust ments sec-
tion of the Service Manual for these mainte nance
procedures.

NOTCHING OR UNDERCUTTING
1. The notching or undercutting cut is made on the side
you want the tree to fall. Place the saw so the hand
guard is close to the tree trunk and the bucking cleat
is dug in.
2. Start the cut horizontally. Pivot the nose of the bar in
last. Cut to about one-quarter of the tree’s diameter.
3.
WARNING
Watch out for falling limbs.
Make a diagonal cut down to meet the hori zontal cut
and remove the wood from the notch.
