duced--kickback guide bars and low--kick-

back saw chains reduce the chance and

magnitude of kickback and are recom-

mended. Your saw has a low kickback chain

and bar as original equipment. If the brake

band is worn too thin it may break when the

chain brake is triggered. With a broken brake

band, the chain brake will not stop the chain.

The chain brake should be replaced by an

authorized service dealer if any part is worn

to less than 1/32” thick. Repairs on a chain

brake should be made by an authorized ser-

vice dealer. Take your unit to the place of pur-

chase if purchased from a servicing dealer,

or to the nearest authorized master service

dealer.
S

This saw is equipped with a chain brake.

The brake is designed to stop the chain if

kickback occurs.

The inertia--activated chain brake is

activated if the front hand guard is pushed

forward, either manually (by hand) or

automatically (by sudden movement).

If the brake is already activated, it is

disengaged by pulling the front hand guard

back toward the front handle as far as

possible.

When cutting with the saw, the chain brake

must be disengaged.

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. Hold the han-

dles with both hands and apply full throttle.

Activate the chain brake by turning your left

wrist against the hand guard without releas-

ing your grip around the front handle. The

chain should stop immediately.

WARNING:

When performing the

following procedure, the engine must be

turned off.

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

after 1 minute of operation. See CHAIN

TENSION in the ASSEMBLY section.

Cut wood only. Do not cut metal, plastics,

masonry, non-wood building materials,

etc.

Stop the saw if the chain strikes a foreign

object. Inspect the saw and repair or re-

place parts as necessary.

Keep the chain out of dirt and sand. Even a

small amount of dirt will quickly dull a chain

and thus increase the possibility of kick-

back.

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.

Squeeze the throttle trigger and al-

low the engine to reach full speed

before cutting.

Begin cutting with the saw frame

against the log.

Keep the engine at full speed the en-

tire time you are cutting.

Allow the chain to cut for you. Exert

only light downward 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 without a cutting load, un-

necessary wear can occur to the

chain, bar, and engine.

To avoid losing control when cut is

complete, do not put pressure on

saw at end of cut.

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 plan your sawing operation in ad-

vance.

Clear the work area. You need a clear area

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:
S

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.
