• Remove dirt,stones, loose bark,
nails,staples, and wire fromthe tree
where cuts are to be made.
Plan a clear retreatpath
. ....-,"- .,-

A retreat path should be planned and
cleared as necessary before cuts are
started. The retreat path should extend
back and diagonally tothe rear ofthe
e_-'ted rm offallas illusl_ed abeve.
FELLING LARGE TREES
_6hinchesin diameter or larger)
e notchmethod ksused tofell large
trees. A notch is cuton the side ofthe
tree inthe desired directionof fall. After
a fellingcut is made on the opposite
side of tree, the tree will tend to fall in
the directionofthe notch.
NOTE: Iftree has large buttress roots,
removethem before making the notch.
NOTCH CUT AND FELLING TREE
• Make notchcut by cuffingthe top of
the notch first. Cut through 1/3 otthe
diameter ofthe tree. Next complete
the notch by cuffingthe bottom. See
illustration.Once notchiscut, remove
the wedge of wood fromthe tree.
• After removingthe wood, make the
fellingcut on the opposite side ofthe
• notch. This is done by making a cut
about twoinches higherthan the cen-
ter ofthe notch. Thkswillleave
enough uncutwood between the fell-
ing cut and the notchto form a hinge.
This hinge willhelp prevent the tree
from fallingin the wron direction.

Notching Undercut - Make the notch
1/3 the diameter ofthe tree, perpendic-
ularto the directionoffall as illustrated.
Make the lower horizontal notchingcut
fl..rs.LThis will help to avoid pinchingof
eithe.r,the saw chain or the guide bar
when tllrSecond notch isbeing made.
Felling Back Cut - Make the felling
back cut at least 2 inches (50.Bmm)
higherthan the horizontalnotchingcut
as illustrated.Keep the fellingback cut
parallel tothe horizontalnotchingcut.
Make the felling backcut so enough
wood isleft to act as a hinge.The hinge
wood helpsthe tree fromtwistingand
fallingin the wrong direction. Do notcut
through the hinge.

NOTE: Before fellingcut is complete,
use wedges to open the cut when
necess.aryto controlthe direction offall.
Toavoid kickback and chaindamage,
use wood or plasticwedges, but never
steel or ironwedges.
• Be alertto signsthat the tree is ready
tofall: crackingsounds,widening of
the fellingcut, or movement in the up-
. per branches.
As tree startsto fall,stop saw, put it
down, and get away quicklyonyour

• Be extremaly sautious with partially
fallen trees that may be poorlysup-
ported. When a tree doesn'tfall com-
pletaiy,set the saw aside and pull
downthe tree witha cable winch,
blockand taclde, or tractor.Do not
useyour saw to cut downa partially
