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:
Note: Be sure to adjust the carburetor with the bar chain
attached.
1.Stop engine and screw in both the H and L needles
until they stop.Never force them.Then set them back the
initial number of turns as shown below.
H needle:
3/4
±
3/8
L needle:
1
1/2
±
1/4
2.Start the engine and allow it to warm up at half-throttle.
3.Turn the L needle slowly clockwise to find a position
where idling speed is maximum, then set the needleback a
quarter (1/4) turn counterclockwise.
4.Turn the idle adjusting screw (T) counterclockwise so that
the saw chain does not turn. If the idling speed istoo slow,
turn the screw clockwise.
5. Make a test cut and adjust the H needle for best cutting
power, not for maximum speed.
