RELEASE THE CHAIN BRAKE
• When front hand guard is fully pulled towards
the operator, chain brake is released.
• If the chain does not stop immediately, bring
the saw to your dealer to repair.
WARNING DANGER
Most hazardous is the kickback motion of the
guide bar such that, in an instant the tip of the
bar touches a wood or the like. Chain brake
reduced the possibility of injury due to kickback.
You must always check that chain brake works
properly before use.
NON-MANUAL CHAIN BRAKE
The non-manual chain brake stops the operation
of the saw chain in such a manner that kickback
action produced at the end of the guide bar non-
manually actuates the chain brake.
To make sure that the non-manual chain brake
operates properly, proceed as follows:
a.
Stop the engine of the chain saw.
b.
Operate the front and rear handles with hands
(grip them lightly), so that the guide bar may be
placed at the height of about 35cm as shown in
Fig.
NOTE
• For practice, while cutting a small tree, push
the front guard forward to engage the brake.
•
At all times, confirm whether the brake works
properly before each work.
• If the chain brake is clogged with wood chips,
function of the brake deteriorates a little.
Always keep the device clean.
• Do not increase engine revolution while the
chain brake is engaged.
• When using throttle latch at starting, keep the
chain brake position. And after starting the
engine, release the brake immediately.
• Never test the brake in an area where petrol
fumes are present.
• Softly detach the left hand from the front
handle, and touch the end of the guide bar
against the wood or the like placed below so
that the machine receives an impact. (*at this
time the rear handle should be gripped lightly
with right hand).
• The impact is propagated to the brake lever,
which actuates the chain brake.
PRECAUTION
When checking the operation of the non-manual
chain brake, use a soft surface substance like
wood to provide the impact so the saw chain is
not damaged.
GENERAL CUTTING INSTRUCTIONS
In all circumstances the operation of the chain
saw is a one-man job. It is difficult at times to
take care for your own safety, so don’t assume
the responsibility for a helper as well. After you
have learned the basic techniques of using
the saw, your best aid will be your own good
common sense.
The accepted way to hold the saw is to stand to
the left of the saw with your left hand on the front
handle so you can operate the throttle trigger
with your right index finger.
Before attempting to fell a tree, cut some small
logs or limbs. Before thoroughly familiar with the
control and the responses of the saw.

THE BRAKE
NON-MANUAL CHAIN BRAKE
•Release throttle trigger and turn ignition switch down.
NOTE
When engine does not stop, pull choke control knob
all the way out to stop engine.
Check and repair ignition switch before starting the
engine again.
•Chain tension should be checked frequently during
work and corrected if necessary.
•Tension the chain as tight as possible, but so it can
still be pulled easily along the bar by hand.
WARNING ▲ DANGER
MAKE SURE THAT THE ENGINE IS SHUT OFF
WHEN CHECKING CHAIN TENSION.
1) Place the chain saw on the ground.
2) Hold the handle with both hands and accelerate the
engine to high speed by throttle trigger.
3) Operate the chain brake by turning your left wrist
against the front hand guard during your grip on the
front handle.
4) The chain stop immediately.
5) Release the throttle trigger.
•Familiarize yourself with your chain saw before you
start actual cutting.
•For this purpose it may be wise to practice by cutting
some small logs or limbs several times.
•Do not allow either people or animal into the work
area. Multiple operators - Keep a safe distance
between two or more operators when working
together simultaneously.
Hold the chain just above a dry surface and open the
throttle to half speed for 30 seconds
A thin line of “thrown” oil should be seen on the dry
surface.
•When front hand guard is fully pulled towards the
operator, chain brake is released.
If the chain does not stop immediately, bring the saw to
your dealer to repair.
WARNING ▲ DANGER
MOST HAZARDOUS IS THE KICKBACK MOTION OF
THE GUIDE BAR SUCH THAT, IN AN INSTANT THE
TIP OF THE BAR TOUCHES A WOOD OR THE LIKE.
CHAIN BRAKE REDUCES THE POSSIBILITY OF
INJURY DUE TO KICKBACK.
YOU ALWAYS CHECK THAT CHAIN BRAKE WORKS
PROPERLY BEFORE USE.

Start the engine, see that is running properly. Squeeze
the trigger to open the throttle wide open, then start the
cut. It is not necessary to press down hard to make the
saw cut. If the chain is properly sharpened, the cutting
should be relatively effortless.
Pushing the saw too hard will slow the engine and
cutting will actually be more difficult.
Some material may adversely affect the housing of your
chain saw.
(Example: palm tree acid, fertilizer etc.)
To avoid housing deterioration carefully remove all
packed saw dust around clutch and guide bar area and
wash with water.
