Begin cutting with the saw frame

against the log.

Keep the engine at full speed the entire

time you are cutting.

Allow thechaintocutforyou. Exert only

light downward pressure. If you force

the cut, damage tothe bar,chain, oren-

gine can result.

Release the throttle trigger as soon as

the cut is completed, allowing the en-

gine to idle. If you run the saw at full

throttle without acutting load, unneces-

sary wear can occur to the chain, bar,

and engine.

Toavoid losing control whencut iscom-

plete, donotputpressure onsawatend

Stop the engine before setting the saw

down after cutting.

TREE FELLING TECHNIQUES

WARNING:

Check for broken or

dead branches which can fall while cutting

causing serious injury. Do not cut near build-

ings or electrical wires if you do not know the

direction of tree fall, nor cut at night since you

will not be ale to see well, nor during bad

weather such as rain, snow, or strong winds,

etc.

Carefully planyoursawing operation inad-

vance.

Cleartheworkarea. You need acleararea

all around the tree so you can have secure

footing.

Study the natural conditions that can cause

the tree to fall in a particular direction.

Natural conditions that can cause a tree to

fall in a particular direction include:

The wind direction and speed.

The lean of the tree. The lean of a tree

might not be apparent due to uneven or

sloping terrain. Useaplumb orlevel to de-

termine the direction of tree lean.

Weight and branches on one side.

Surrounding trees and obstacles.

Look for decay and rot. If the trunk is rotted, it

can snap and fall toward the operator. Check

for broken or dead br anches which can fall on

you while cutting.

Make sure there is enough room for the treeto

fall. Maintain a distance of

2-1/2

tree lengths

from the near est person or other objects. En-

gine noise can dr ow n out a warning call.

Removedirt, stones, loose bark, nails, staples,

and wire from the tree wher e cuts are to be

made.

Plan a clear retreat path to the rear and diag-

onal to the line of fall.

FELLING LARGE TREES

(6 inches in diameter or larger)

The notch method is used to fell large trees.

Anotch is cut on the side ofthe treeinthede-

sired direction of fall. After a felling cut is

made on the opposite side of tree, the tree

will tend to fall into the notch.

NOTE:

If the tree has large buttress roots,

remove them before making the notch. If us-

ing saw to remove buttress roots, keep saw

chain from contacting ground toprevent dull-

ing of the chain.

NOTCH CUT AND FELLING THE

TREE

Make notch cut by cutting the top of the

notch first. Cut through

1/3

of the diameter

ofthe tree. Nextcomplete thenotch bycut-

ting the bottom of the notch. See illustra-

tion. Once the notch is cut remove the

notch of wood from the tree.

Final (felling) cut here. 2 inches

above center of notch.

Hinge

After removing the cutout of wood, make

the felling 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 tree on stump and helps

control fall

NOTE:

Before felling cut is complete, use

wedges to open the cut when necessary to

control the direction of fall. Toavoid kickback

and chain damage, use wood or plastic

wedges, but never steel or iron wedges.

Be alert to signs that the tree is ready to fall:

crack ing sounds, widening of the felling cut,

or movement in the upper branches.

As tree starts to fall, stop saw, put it down,

and get away quickly on your planned re-

treat path.
