Tree Felling Techniques - Craftsman 358.355060 Operator's Manual

b. Begin
cutting with the saw frame against the
Iog_. F igure 24.
c. Keep the engine at full throttle the entire time
you are cutting.
d. Allow the chain to cut for you; exert only light
downward pressure. If you force the cut, dam-
age to the bar, chain or engine can result.
e. Release the throttle trigger as soon as the cut
is completed, allowing the engine to idle. Ifyou
run the saw at full throttle without a cutting
load, unnecessary wear can occur to the
chain, bar, and engine.
f. Do not put pressure on the saw at the end of
the cut to avoid losing control when the cutis
complete.

g. Stop the engine before setting the saw down

1. PLANYOUR SAWING OPERATION CARE-:
FULLY IN ADVANCE
a. Ctear the workaraa. You need a clear areaali
around .the tree where you can have secure •
footing.
b. Studythe naturaiconditionsthat can cause -
thetree to fall in a particular direction:
1.) The WIND direction and speed
2.) The LEAN ofthetree .............
3.) WBGHTED with BRANCHES on one side
4.) Surrounding TREES and OBSTACLES
c. Look for decay and rot. If the trunk is rotted,
it could snap aridfall toward the operator.
d. Check for broken or dead branches which
could fall on you while cuffing.
e. Make sure there is enough room for the tree
to fall. Maintaining a distance of 21,_ tree
lengths from the nearest person or other ob-
jects. Engine noise may drown out warning
call -
f. Remove dirt, stones, loose bark, nails,
staples, and wire from the tree where cuts
areto be made.
g. Plan to stand on the up-hill side when cut-
ring on a slope.
h. Plan a .c.lcar retreat path to the rear. and
diagonalto the line of fall. Figure 26.
WARNING!
DONOTCUT:
-- near electrical wires or buildings.
uif you do not knowthe direction of tree fall.
at night since you will not be ableto see well.
_during bad weather-- strong wind, snow, rain,
etc.

2..FELLING SMALL TREES-- LESS THAN 6"
........ IN DIAMETER
a. lfyou knowthe direction offall:
1.) Ma$'.ea single felling:cut on the side away- ....
from the direct{onof fall .... "
b.
2.) Cut allthe waythrough.
3.) Stop the saw, put it down, and get away
quickly on your planned retreat path.
If you are not sure which way the tree will fall,
use the notch method described for felling
large trees.
3. FELLING LARGE TREES m 6" DIAMETER
• OR MORE
The notch method is used to cut large trees: A
notch is cut on the side of the tree in the desired
direction of fall. After a felling cut ismade on the
opposite side of the tree, the tree will tend to fall
intothe notch.
NOTE: If the tree has large buttress roots, re-
move before making the notch. CUt into the but-
tresses vertically, then hodzontaily. FKjure25
a. Make the notch cut. Figure27.
,
1.) Cut the bottom of the notch first, through
1/3 ofthe diameter of the tree.
2.) Complete the notch by making the slant
cut.
3.) Removethe notch ofwood.
b. Make the felling cut onthe oppositeside ofthe
notch about 2" higher than the bottom of the
notch.
