ADJUSTING CARBURETOR
The carburetor on your unit has been adjusted
by the
factory, but may require fine turning due to change in
operating conditions.
Before adjusting the carburetor, make sure that
provided are clean air/fuel filters and fresh, properly
mixed fuel.
When adjusting, take the following steps.
a. Stop engine and screw in both H and L needles until they stop. Never force.
Then set them back the initial number of turns as show below.
H needle:
1+-3/8
L needle:
5/4+-1/4
b. Start engine and allow it to warm up at half-throttle.
c. Turn L needle slowly clockwise to find a position where idling speed is
maximum, then set the needle back a quarter (1/4) turn counterclockwise.
d. Turn idle adjusting screw (T) counterclockwise so that saw chain does not
turn. If idling speed is to slow, turn the screw clockwise.
e. Make a test cut and adjust the H needle for best
cutting power, not for maximum speed.
