In all circumstances the operation of the chain
saw is a one-man job.
It is dif

cult at times to take care for your own

safety, so don’t assume the responsibility for a
helper as well.
After you have learned the basic techniques of
using the saw, your best aid will be your own
good common sense.
The accepted way to hold the saw is to stand
to the left of the saw with your left hand on
the front handle so you can operate the throttle
trigger with your right index

nger.

Before attempting to fell a tree, cut some small
logs or limbs.
Be familiar with the controls and the responses
of the saw thoroughly.
Start the engine, see that is running properly.
Squeeze the trigger to open the throttle wide
open, then start the cut. It is not necessary to
press down hard to make the saw cut. If the
chain is properly sharpened, the cutting should
be relatively effortless.
Pushing the saw too hard will slow the engine
and cutting will actually be more dif

cult.

DANGER

Do not let the nose or tip of the guide
bar touch anything while engine is
running to avoid kickback.

Some material may adversely affect the
housing of your chain saw.
(Example: palm tree acid, fertilizer etc.)
To avoid housing deterioration carefully
remove all packed saw dust around clutch and
guide bar area and wash with water.

Cutting Instruction

General

A falling tree can seriously damage anything it
may hit a car, a house, a fence, a powerline or
another tree.
There are ways to make a tree fall where you
want it, so

rst decide where that is!

Before cutting, clear the area around the tree.
You will need good footing while working and
you should be able to work the saw without
hitting any obstacles.
Next select a path of retreat.
When the tree begins to fall you should retreat
away from the direction of fall at a 45-degree
angle and at least 3 m from the trunk to avoid
the trunk kicking back over the stump. (See
above

gure)

Begin the cut on the side to which the tree is
to fall.
Cut a notch approximately 1

3 of the way into

the tree. (See

gure A)

The position of this notch is important since
the tree will try to fall “into” the notch. (See

gure A)

The felling cut is made on the side opposite
the notch.
Make the felling cut placing spiked bumper
2.5 cm to 5 cm above the bottom of the notch
and stop cutting at approximately 1

10 of

diameter to the inner edge of the notch (See

gure B) in order to leave the uncut portion of

the wood as a hinge.
Do not try to cut through to the notch with the
felling cut.
The remaining wood between the notch cut
and felling cut will act as a hinge when the
tree falls, guiding it in the desired direction.
When the tree starts to fall, kill the engine,
place the saw on the ground and make your
retreat quickly.
To fell big trees with a diameter exceeding
twice the bar length start the notching cuts
from one side and draw the saw through to the
other side of the notch.
Start the back cut on one side of the tree with
spiked bumper engaged, pivoting the saw
through to form the desired hinge on that side.

Then remove the saw for the second cut.
Insert the saw in the

rst cut very carefully so

as not to cause kickback.
The

nal cut is made by drawing the saw

forward in the cut to reach the hinge. (See

gure C)
