The carburetor on your unit has been factory adjusted, but may require fine tuning due to a change in operat- ing conditions.
Before adjusting the carburetor, make sure that the pro- vided air/fuel filters are clean and fresh and the fuel prop- erly mixed.
When adjusting, take the following steps:
Note: Be sure to adjust the carburetor with the bar chain attached.
1.H and L needles are restricted within the number of turn as shown below.

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
This machine is equipped with an automatic brake to stop saw chain rotation upon occurrence 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 operation during daily inspec- tion.
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 stump or a piece of wood, and confirm brake op- eration. Operating level varies by bar size.
In case the brake is not effective, ask our 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, immediately release the throttle lever to stop the engine.
■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.
