CUTTING METHODS

IMPORTANT POINTS

• Cut wood only. Do not cut metal, plastics,

masonry, noivwood building materials,

6tC.

• Stop the saw if the chain strikes a foreign

object. Inspect the saw and repair parts

as necessa^.

• Keep the chain out of dirt and sand. Even

a small amount of dirt will quickly dull a

chain and increase the possibility of kick

back.

• Practice cutting a few small logs using the

following techniques to get the “feel’ of

using your saw before you begin a major

sawing operation.

• Squeeze the throttle trigger and allow the

engine to reach full speed before cutting.

• Begin cutting with the saw frame against

the log. .

• Keep the engine at full speed the entire

time you are cutting.

• Allow the chain to cut for you. Exert only

light downward pressure.

• Release the throttle trigger as soon ^ the

cut is completed, allowing the engine to

idle. If you run the saw at full throttle with

out a cutting load, unnecessary wear can

occur.

• To avoid losing control when cut is com

plete, do not put pressure on saw at end

of cut.

• Stop the engine before setting the saw

down.

TREE FELLING TECHNIQUES

idk WARNING:Donotcutnearbuildings

or electrical wires if you do not know the di

rection of tree fall, at night since you will not

be able to see well, or during bad weather

such as rain, snow, or strong winds, as fall Is

unpredictable.

Carefully plan your sawing operation in ad

vance. You need a clear area all around the

tree so you can have secure footing. Check

for broken or dead branches which can fall

on you causing serious injury.

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. Use a plumb or level to

determine the direction of tree lean.

• Weight and branches on one side.

• Surrounding trees and obstacles.

Lx)ok for decay and rot If the trunk is

rotted, it can snap and fall toward the

operator.

Make sure there is enough room for the tree

to fail. Maintain a distance of 2-1/2 tree

lengttisfrom the nearest person or other ob

jects. Engine noise can drown out a warn

ing call.

Remove dirt, stones, loose bark, nails, sta

ples, and wire from the tree where cuts are

to be made.

Plan a clear retreat path

- Direction of Fall

FELLING LARGE TREES

(6 inches In diameter or larger)

The notch method is used to fell large trees.

A noteh is cut on the side of the tree in the

desired direction of fall. After a felling cut is

made on the opposite side of tree, the tree

will tend to fall into the notch.

NOTCH CUT AND FELUNG THE TREE

• Make notch cut by cutting the top of the

notch first Cut through 1 /3 of the diameter

of the tree. Next complete the notch by

cutting the bottom of the notch. See il

lustration. Once the notch is cut remove

the notch of wood from the tree.

• 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 ttie wrong direction.

Final cut here. 2 inches abov

NOTE: Before felling cut Is complete, use

wedges to open the cut when necessary to
