Braking function control

CAUTION:

The chain brake must be

checked several times daily. The engine

must be running when performing this proce-

dure. This is the only instance when the saw

should be placed on the ground with the en-

gine running.

Place the saw on firm ground. Grip the rear

handle with your right hand and the front han-

dle with your left hand. Apply full throttle by

fully depressing the throttle trigger. Activate

the chain brake by turning your left wrist

against the hand guard without releasing

your grip around the front handle. The chain

should stop immediately.

Inertia activating function control

WARNING

:

When performing the fol-

lowing procedure, the engine must be turned

off.

Grip the rear handle with your right hand and

the front handle with your left hand. Hold the

chain saw approximately 14” (35 cm) above

a stump or other wooden surface. Release

your grip on the front handle and use the

weight of the saw to let the top of the guide

bar fall forward and contact the stump.

When the tip of the bar hits the stump, the

brake should activate.

CUTTING METHODS

IMPORTANT POINTS

S

Check chain tension before first use and af-

ter 1 minute of operation. See CHAIN TEN-

SION in the ASSEMBLY section.

S

Cut wood only. Do not cut metal, plastics,

masonry, non-wood building materials, etc.

S

The bumper spike may be used as a pivot

when making a cut.

S

Stop the saw if the chain strikes a foreign

object. Inspect the saw and repair parts as

necessary.

S

Keep the chain out of dirt and sand. Even a

small amount of dirt will quickly dull a chain

and increase the possibility of kickback.

S

Practice cutting a few small logs using the

following techniques to get the “feel” of us-

ing your saw before you begin a major

sawing operation.

S

Squeeze the throttle trigger and allow the

engine to reach full speed before cutting.

S

Begin cutting with the saw frame

against the log.

S

Keep the engine at full speed the entire

time you are cutting.

S

Allow the chain to cut for you. Exert only

light downward pressure.

S

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 a cutting load, unneces-

sary wear can occur.

S

To avoid losing control when cut is com-

plete, do not put pressure on saw at end

of cut.

S

Stop the engine before setting the saw down.

TREE FELLING TECHNIQUES

WARNING

:

Do not cut near buildings

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:

S

The wind direction and speed.

S

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 de-

termine the direction of tree lean.

S

Weight and branches on one side.

S

Surrounding trees and obstacles.

Look 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

fall. Maintain a distance of

2-1/2

tree lengths

from the nearest person or other objects. En-

gine noise can drown out a warning call.

Remove dirt, stones, loose bark, nails, staples,

and wire from the tree where cuts are to be

made.

Direction of Fall

Plan a clear retreat path

FELLING LARGE TREES

(15 cm in diameter or larger)

The notch method is used to fell large trees.

A notch is cut on the side of the tree in the de-

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.

NOTCH CUT AND FELLING THE

TREE

S

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 cut-

ting the bottom of the notch. See illustra-

tion. Once the notch is cut remove the

notch of wood from the tree.
