■ ADJUSTING CARBURETOR (OP9)
The carburetor on your unit has been factory
adjusted, but may require fine tuning 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:
Be sure to adjust the carburetor with the bar chain
attached.
1. H and L needles are restricted within the number
of turn as shown below.
H needle –1/4
L needle –1/4
2. Start engine and allow it to warm up in low
speed for a few minutes.
3. Turn idle adjusting screw (T) counter-clockwise
so that saw chain does not turn. If idling speed is
too slow, turn the screw clockwise.
4. Make a test cut adjust the H needle for best
cutting power, not for maximum speed.
(1) L needle
(2) H needle
(3) Idle adjusting screw
■ CHAIN BRAKE (OP10)
The chain brake is a device which stops the chain
instantaneously if the chain saw recoils due to
kickback.
Normally, the brake is activated automatically by
inertial force. It can also be activated manually by
pushing the brake lever (left-hand guard) down
toward the front.
When the brake operates, a yellow cone pops up
from the base of the brake lever.
Releasing the Brake
Pull the brake lever up toward the left-hand handle
until it clicks into place.
