CHAIN BRAKE

a WARNING: 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 0.5 mm (0.020 in) thick. Repairs

on a chain brake should be made by an

authorized service dealer.

Take your unit to the place of purchase if

purchased from a servicing dealer, or to the

nearest authorized master service dealer.

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 locked if the front

hand guard is pushed forward, either manually (by

KDQGRUDXWRPDWLFDOO\E\VXGGHQPRYHPHQW

If the brake is already locked, it is unlocked by pulling

the front handguard back toward the front handle as

far as possible.

When cutting with the saw, the chain brake must be

unlocked.

BRAKING FUNCTION CONTROL

NOTE: The chain brake must be checked several

times daily. The engine must be running when

performing this procedure.

This is the only instance when the saw should be

placed on the ground with the engine running.

with your right hand and the front handle 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.

CHECKING THE INERTIA ACTIVATING FUNCTION

CONTROL

a WARNING! When performing the following

procedure, the engine must be turned off.

1. Grip the rear handle with your right hand and the

front handle with your left hand.

2. Hold the chainsaw approximately 40-45

wooden surface.

3. Release your grip on the front handle and use the

weight of the saw to let the tip of the guide bar fall

forward and contact the stump. When the tip of the

bar hits the stump, the brake should activate.

WORKING TECHNIQUES

PRACTICING YOUR CUTS

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 are

cutting.

• Allow the chain to cut for you. Exert only light

downward pressure. If you force the cut, damage to

the guide 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,

unnecessary wear can occur to the chain, guide

bar, and engine. It is recommended that the engine

not be operated for longer than 30 seconds at full

throttle.

• 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.

FELLING A TREE

PLANNING

a WARNING! Check for broken or dead

branches which can fall while cutting

causing serious injury. Do not cut near

buildings 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

Carefully plan your sawing operation in advance.

Clear the work area. You need a clear area all around

the tree so you can have secure footing.

The chainsaw 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 determine 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 objects. Engine 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.

Plan a clear retreat path to the rear and diagonal to
