When adjusting, take the following prompts: 

 

Make sure to adjust the carburetor with the bar 

chain attached. 

 
H and L needles are adjusted by authorized 

persons. The authorized range within the turn 

number as shown below. 

Needle H –1/4 

Needle L –1/4

 

 
2. Start the engine and let it warm up at low 

speed for a few minutes. 

3. Turn the idle speed adjusting screw (T) counterclockwise ○ b so that 

the saw chain does not rotate. If the idle speed is too slow, turn the screw 

clockwise ○ a.

 

4. Make a test cut to adjust the H needle for best cutting power, not 

maximum speed. 
(T) Idle adjusting screw (L) Low speed needle (H) High speed needle 
 

 

CHAIN BRAKE

 

The chain brake is a device that stops 

the chain instantly if the chain saw 

backs up due to kickback. 

 

Normally, the brake is activated 

automatically by inertial force. Can also 

be activated manually 
Pushing the brake lever (front 

handlebar guard) down. When the 

brake works, a white cone comes out of the base of the brake lever. To 

release the brake, lift the front handle shield toward the front handle until 

a clicking sound is heard. 

When the brake comes on, release the throttle trigger to reduce engine 
speed. Continuous operation with the brake engaged will generate heat 
from the clutch and can cause problems. 
 

Be sure to check the operation of the brake in the daily inspection.
