How to confi rm:
1) Tu rn off the engine.
2) Holding the chain saw horizontally, release your hand from the
front handle, hit the tip of the guide bar to a stump or a piece
of wood, and confi rm brake operation. Operating level varies by
bar size.
Fig. 13
In case the brake is not eff ective, ask our dealer for inspection and
repairs. If the engine keeps rotating at high speed with the brake
engaged, the clutch will overheat causing trouble.
When the brake engages during operation, immediately release the
throttle lever to stop the engine.
WARNING
Do not carry the machine with the engine running.
Stopping (Fig. 14)
Decrease engine speed, and push ignition switch (14) to stop
position.

WARNING
KICKBACK DANGER (Fig. 15)
One of the most severe dangers when working with a chain saw
is the possibility of kickback. Kickback may occur when the upper
tip of the guide bar touches an object, or when the wood closes in
and pinches the saw chain in the cut. Tip contact
in some cases
may cause a lightning fast reverse reaction, kicking the guide bar
up and back toward you. Pinching the saw chain along the top of
the guide bar may also push the guide bar rapidly back towards you.
Either of these reactions may cause you to lose control
of the saw
which could result in serious personal injury. Even though your saw
has safety built into its design, you should not rely on these safety
features exclusively. Know where your bar tip is at all times. Kickback
does occur if you allow the kickback zone (17) of the bar
to touch an
object. Do not use that area. Kickback from pinching is caused by a
cut closing and pinching the upper side of the guide bar. Study your
cut and make sure it will open as you cut through. Maintain control
when the engine is running by always keeping
a fi rm grip on the saw
with your right hand on the rear handle, your left hand on the front
handle and your thumbs and fi ngers encircling the handles. Always
hold the saw with both hands during operation and cut at high engine
speed.

WARNING
○ Do not overreach or cut above shoulder height.
○ Use extra caution when felling, and do not use the saw in a nose-
high position or above shoulder height.
CHAIN CATCHER
The chain catcher is located on the power head just below the chain
to further prevent the possibility of a
broken chain striking the chain
saw user.
WARNING
Do not stand in-line with chain when cutting.
BASIC TECHNIQUES FOR MAKING FELLING, LIMBING AND
BUCKING CUTS
The intention of the following information is to provide you with the
general introduction to wood cutting techniques.
WARNING
○ This information does not cover all specifi c situations, which
may depend on diff erences in terrain, vegetation, kind of wood,
form and size of trees, etc. Consult your servicing dealer,
forestry agent or local forestry schools for advice on specifi c
woodcutting problems in your area. This will
make your work
more effi cient and safer.
○ Avoid cutting in adverse weather conditions, such as dense fog,
heavy rain, bitter cold, high winds, etc.
Adverse weather is often tiring to work in and creates potentially
dangerous conditions such as slippery ground.
High winds may force the tree to
fall in an unexpected direction
causing property damage or personal injury.
CAUTION
Never use a chain saw to pry or for any purpose for which it is not
intended.
WARNING
○ Avoid stumbling on obstacles such as stumps, roots, rocks,
branches and fallen trees. Watch out for holes and ditches. Be
extremely cautious when working on slopes or uneven ground.
Shut off the saw when moving from one work place to another.
Always cut at wide open throttle. A slow
moving chain can easily
catch and force the saw to jerk.
○ Never use the saw with only one hand.
You cannot control the saw properly and you may lose control
and injure yourself severely.
Keep the saw body close to your body to improve control and
reduce strain.
○ When
cutting with the bottom part of the chain the reactive
force will pull the saw away from you towards the wood you are
cutting.
The saw will control the feeding speed and sawdust will be
directed towards you. (Fig. 16)

○ When cutting with the upper part of the chain the reactive force
will push the saw towards you and away from the wood you are
cutting. (Fig. 17)
