Do not adjust the carburettor unless necessary.
To adjust the carburettor proceed as follows:
- Turn the low speed mixture adjuster (L) and high speed mixture adjuster (H)
anticlockwise to stop.
- Start engine and allow it to run at high idle until warm.
- Turn the idle speed adjuster (T) anticlockwise until the saw chain stops moving.
- Turn idle speed adjuster (T) anticlockwise an additional 1/2 turn.
- Accelerate to full throttle to check for smooth transition from idle to full throttle.
Cylinder fins (Cooling system)
Check periodically.
Clogged fins will result in poor engine cooling.
Remove dirt and dust from between fins to let cooling air pass easily.
