1.H and L needles are restricted within the number of turn 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.

WARNING

•	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 trouble.
•	At machine inspection prior to each job, check the
	operating condition of the brake following the steps. G
1.	Start the engine and grasp the handle securely with	B
	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.

WARNING

•Before proceeding to your job, read the section “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 regu- lations. The chain saw must only be used for cutting wood. It is forbidden to cut other types of material. Vibrations and kickback vary with differ- ent materials and the require- ments of the safety regulations would not be respected. Do not use the chain saw as a le- ver for lifting, moving or split- ting objects. Do not lock it over fixed stands. It is forbidden to hitch tools or applications to the PTO other than those specified by the manufacturer.

•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.
