When cutting with the saw, the chain brake

must be disengaged.

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. 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.

Inertia activating function control

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 parts as

necessary.

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.

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 cut-

ting.

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 as

the cut is completed, allowing the engine

to idle. If you run the saw at full throttle

without a cutting load, unnecessary

wear can occur to the chain, bar, and en-

gine. It is recommended that the en-

gine not be operated for longer than

30 seconds at full throttle.

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

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 able to see well, nor during bad

weather such as rain, snow, or strong winds,

etc. If the tree makes contact with any utility

line, the utility company should be notified

immediately.
S

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.

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 direc-

tion.

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.

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 distance of

2-1/2

tree

lengths from the nearest person or other ob-

jects. Engine 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.
