2. Start the engine and allow it to warm up at half-throttle.
3. Turn the ‘L’ needle slowly clockwise to find a position
where idling speed is maximum, then set the needle back a
quarter (1/4) turn counterclockwise.
4. Turn the idle adjusting screw ‘T’ counterclockwise so that
the saw chain does not turn. If the idling speed is too slow,
turn the screw clockwise.
5. Make a test cut and adjust the ‘H’ needle for best cutting
power, not for maximum speed.
Chain Brake
This machine is equipped with an
automatic brake to stop the saw
chain rotating should kickback
occur while the saw is being used
for cutting. The brake is automati-
cally operated by inertial force
which acts on the weight fitted
inside the front guard. This brake
can also be operated manually with the Front guard push
forward to the guide bar. To release brake, pull up the Front
guard toward the Front handle till ‘click’ sound is heard.
WARNING!
The kickback reaction happens so quickly that you will not be
able to react in time to avoid serious injury, even if the chain
brake works. The saw must never be in line with your face,
but should be to the right of your body. Never be distracted.
IMPORTANT!
Be sure to confirm brake operation is functioning correctly by
inspecting daily.
How to confirm brake is functioning correctly.
1. Turn 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, to confirm brake opera-
tion. The Front guard should move away
from you, to the ‘On’ position. Operating
level varies by bar size. If the brake is not effective, ask
your dealer to inspect and repair.
IMPORTANT!
If the engine is kept rotated at high speed while the brake
is engaged, it will overheat the clutch, causing damage.
When the brake is operated while the engine is running,
immediately release your fingers from the throttle lever and
drop the engine speed to idle.
Sawing
WARNING!
• Before proceeding to your job, read the ‘Safety Instruc-
tions’ section at the beginning of this Manual. It is recom-
mended to first practice sawing easy logs. This also helps
you get accustomed to your machine.
• Always follow the safety regulations. The chainsaw must
only be used for cutting wood. Never attempt to cut other
types of material due to vibrations and kickback which will
vary with different materials and the requirements of the
safety regulations would not be followed. Do not use the
Brake onBrake off
chain saw as a lever for lifting, moving or splitting objects.
Do not lock it over fixed stands. Never hitch tools or devic-
es to the P.T.O. that are not specified by the manufacturer.
• It is not necessary to force the saw into the cut. Apply only
light pressure while running the engine at full throttle.
• When the saw chain is caught in the cut, do not attempt to
pull it out by force, but use a wedge or a lever to open the
cut.
GUARDING AGAINST KICKBACK
This saw is equipped with a chain
brake that will stop the chain in the
event of kickback when operating
properly. You must check the chain
brake operation before each usage.
Run the saw at full the throttle for
twelve seconds and push the Front
guard forward. The chain should
stop immediately with the engine
at full speed. If the chain is slow
to stop or does not stop, you must
replace the brake band and clutch drum before use. See your
chainsaw dealer.
WARNING!
It is extremely important that the chain brake is checked for
proper operation before each use and that the chain is sharp
in order to maintain the Kickback safety function of this saw.
Removal of safety devices, inadequate maintenance, or
incorrect replacement of the bar or chain may increase the
risk or serious personal injury or death due to kickback.
FELLING A TREE
1. Decide the felling direction. Consider the wind, lean of the
tree, location of heavy branches, ease of work after felling
and other factors
2. While clearing the area around the
tree, arrange a good foothold and
retreat path.
3. Make a notch cut one third of the
way into the tree on the felling side,
1.
4. Make a felling cut from the oppo-
site side of the notch and at a level
slightly higher than the bottom of
the notch, 2.
WARNING!
When you fell a tree, be sure to warn your neighbouring
workers of the danger.
Bucking and Limbing
WARNING!
•Always ensure your footing. Do not stand on the log.
•Be alert to the rolling over of a cut log. Especially when
working on a slope, stand on the uphill side of the log.
•Follow the instructions in ‘Safe Operation’ to avoid kickback
of the saw.
Before starting work, check the direction of bending force
inside the log to be cut. Always finish cutting from the
oposite side of bending direction to prevent the guide bar
from being jammed in the cut.
Cutting a log lying on the ground.
Saw down halfway,then roll the log over
and cut from the opposite side.
Cutting a log hanging off the ground.
In area ‘A’ saw up from the bottom one
third and finish by sawing down from
the top. In area ‘B’ saw down from the
