8. ADJUSTING THE CARBURETOR
The carburetor on your unit has been factory adjusted,
but may require fine tuning due to a change in operating
conditions. Before adjusting the carburetor, make sure that the
provided air/fuel filters are clean and fresh and the fuel properly
mixed.
When adjusting, take the following steps:
Adjust the carburetor with the bar chain attached.
1) L needle
2) H needle
3) Idle adjusting screw
1. H and L needles should only be turned 1/4 at a time.
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.
