B. TREE FELLING TECHNIQUES
1. PLAN YOUR SAWING OPERATION CARE-
FULLY IN ADVANCE
a. Clear the work area. Youneeda clear area all
around the tree where you can have secure
footing.
b. Study the natural conditions thatcan cause
the'tree to fall in a particular direction:
1.) The WIND direcfionandspeed.
2.) The LEANofthetree.
3.) WEtGHTED withBRANCHES ononeside.
•4.) ,_urroundingTREES andOBSTACLES.
c. Loolcfordecayandrot. Iftheteankisrotted,itcan
snapand fall towardtheoperator.
.d., Check for broken or dead branches which
couldfall on you whilecutting.
e. Make surethereis enough room for the tree
to fall. Maintain a distance of 2_/_ tree
lengths from the nearest person or other ob-
jects. Engine noisecan drown out a warning
Call.
f. Remove dirt, stones, loose bark, nails,
staples, and wire from the tree where cuts
are to be made.
g. Plan to stand on the up-hill side when cut-
ting on a slope.
h. Plan a clear retreat path to the rear and

WARNING ....
DO NOT CUT:
--=near electrical wires or buildings.
ifyou do not know the direction oftree fall
at night since you will not beable tosee well.
_during bad weather -- strong wind, snow, rain,
etc.
2. FELLING SMALL TREES -- LESS THAN 6"
IN DIAMETER
3.
a. If youknowthe directionoffalh
1.) Make a sing{e felling cut on the side away
from the direction of fall.
2.) Cut _Jfthewaythrough.
3.) Stop the saw, put itdown, and get away
quicklyon your planned retreat path.
b. tf you arc notsure whichway the tree wil!fall,
use the notch method described for felling
large trees.
FELLING LARGE TREES-- 6" DIAMETER
OR MORE
The notch method is used to cut large trees. A
notchis cuton the side of the tree in the desired
directionof fall. After a felling cutis made onthe
oppositeside ofthe tree, the tree will tendto fall
intothe notch.
NOTE: If the tree has large buttress roots, re-
move before making the notch. Cut intothebut-
tressesvertically,then horizontally.Figure24.
a. Make thenotchcut.Figure25.
1:) Cut the bottom ofthe notch first, through
1/.3ofthediameter ofthetree.
2.) Complete the notch by making the slant
cut.
3.) I_emovethe notchofwood.
b. Makethefellingcutontheoppositesideofthe
notchabout 2" higherthan the bottom of the
notch.
DON'T PUT YOURSELF IN THESE POSITIONS
Check the lean,
Don'tcut on lean side.
Check the balance.
Don't cutonweighted s_de.
