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

following procedure, the engine must be

turned off.

Grip the rear handle w ith 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

Check chain tension before first use and af-

ter 1 minute of oper ation. See CH AIN TEN-

SION in the ASSEMBLY sectio n .

Cut w ood only. D o not cut metal, plastics,

masonry, non-wood building materials, etc.

Stop the saw if the chain strikes a foreign ob-

ject. Inspect the saw and repair or replace

parts as necessary.

Keep the chain out of dir t and sand. Even a

small amount of dir t will quickly dull a chain

and thus increa s e the possibility of kickback .

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 ar e cu tting .

Allow the chain to cut for you. Exert only

light downwar d pressure. If you force the

cut, damage to the bar, chain, or engine

can result.

Release the throttle trigger as soon as the

cut is completed, allowing the engine to

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

out a cutting load, unnecessar y wear can

occur to the chain, bar, and engine.

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

after c u ttin g .

TREE FELLING TECHNIQUES

WARNING:

Check for broken or

dead branches which can fall while cutting

causing serious injury. D o 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. If th e tree makes contact with a ny utility

line, the utility company should be notified im-

mediately.

Carefully plan your sawing operation in ad-

vance.

Clear the wor k area. You need a clear area

all around the tr ee so you can have secure

footing.

The chain saw operator should keep on

the uphill side of the terrain as the tree is

likely to roll or slide downhill after it is felled.

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. Use a plumb or level 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 branches which

can fall on you while cutting.

Make sure there is enough room for the tree to

fall. Maintain a dis ta n c e 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, sta-

ples, and wire from the tree where 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.

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.

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 to prevent dull-

ing of the chain.
