NOTE: Be sure to adjust the carburetor with the
bar chain attached.
When adjusting, take the following steps:
1. Stop engine and screw in both the H and L
needles until they stop. Never force them. Then
set them back the initial number of turns as
shown below.
H needle:
3/4 ± 3/8 •
L needle:
1 1/2 ± 1/4
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 coun-
terclockwise.
4. Turn the idle adjusting screw (T) counterclock-
wise so that the saw chain does not turn. If the
idling speed is too slow, turn the screw clock-
wise.
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 saw chain rotation upon occur-
rence of kickback during saw cutting.
The brake is automatically 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 turned down to the guide bar.
To release the brake, pull up the front guard
toward the front handle till a “click” sound is
heard.
CAUTION:
Be sure to confirm brake ope-
ration during daily inspection.
How to confirm?
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 slump or a piece of wood, and
confirm brake operation. Operating level varies
by bar size.
In case the brake is not effective, ask your 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, immedi-
ately release the throttle lever to stop the en-
gine.
STOPPING THE ENGINE
1. Release the throttle lever to allow the engine
to idle for a few minutes.
2. Set the switch to the “O” (STOP) position.
OPERATION
ATTENTION!
• Before proceeding to your job, read the sec-
tion “For Safe Operation”. It is recommended
to first practice sawing easy logs. This also helps
you get accustomed to your unit.
• Always follow the safety regulations. The chain
saw must only be used for cutting wood. It is
forbidden to cut other types of material. Vibra-
tions and kickback vary with different materials
and the requirements of the safety regulations
would not be respected. Do not use the chain
saw as a lever for lifting moving or splitting ob-
jects. Do not lock it over fixed stands. It is for-
bidden to hitch tools or applications to the PTO
other than those specified by the manufacture.
• 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 de way.
GUARD AGAINST KICKBACK
This saw is equipped with a chain brake that will
stop the chain in the event of kickback if oper-
ating properly. You must check the chain brake
operation before each usage by running the
saw at full throttle for 1-2 seconds and pushing
the front hand guard forward. The chain should
stop immediately with the engine at full speed.
If the chain is slow to stop or does not stop, re-
place the brake band and clutch drum before
use.
It is extremely important that the chain brake be
checked for proper operation before each use
and that the chain be sharp in order to maintain
the kickback safety level of this saw. Removal of
the safety devices, inadequate maintenance, or
incorrect replacement of the bar or chain may
increase the risk of serious personal injury due
to kickback.
FELLING A TREE
1. Decide the felling
direction considering
the wind, lean of the
tree, location of heavy
branches, ease of com-
pleting the task after
felling and other fac-
tors.
2. While clearing the area around the tree, ar-
range a good foothold and retreat path.
3. Make a notch cut one-third of the way into
the tree n the felling side.
