Activate the brake
Release
Switch
• When the brake operates, release the throttle lever
to slow down the engine speed. Continuous opera-
tion with the brake engaged will generate heat from
the clutch and may cause overheating or clutch fail-
ure.
• At machine inspection prior to each job, check the
operating condition of the brake following these
steps.
1. Start the engine and grasp the handle securely with
both hands.
2. Pulling the throttle lever to maintain the chain opera-
tion, push the brake lever (left-hand guard) down
toward the front using the back of your left hand.
3. When the brake operates and the chain is stopped,
release the throttle lever.
4. Release the brake.
■ 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.
1. H and L needles are restricted within the number of
turns as shown below.
H needle : -1/4
L needle : -1/4
2. Start the engine and allow it to warm up in low speed
for a few minutes.
3. 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.
4. Make a test cut and adjust the H needle for best
cutting power, not for maximum speed.
■ CHAIN BRAKE
The chain brake is a device which stops the chain in-
stantaneously if the chain saw recoils due to kickback.
Normally, the brake is activated automatically by inertial
force. It can also be activated manually by pushing the
brake lever (left-hand guard) down toward the front.
When the brake operates, a yellow cone pops up from
the base of the brake lever.
Releasing the Brake
Pull the brake lever up and back toward the left-hand
handle until it clicks into place.
• Before proceeding to your job,
read the section “For Safe
Operation”. It is recommended
to first practice sawing small
logs. This also helps you get
accustomed to your unit.
• The chain saw must only be
used for cutting wood. It is for-
bidden to cut other types of
material. Vibrations and kick-
back vary with different mate-
rials. Do not use the chain saw
as a lever for lifting, moving or
splitting objects. Do not lock it
over fixed stands. It is forbid-
den to hitch tools or applica-
tions to the PTO other than
those specified by the manu-
facturer.
• It is not necessary to force the saw into the cut. Ap-
ply 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 way.
