■ ADJUSTING CARBURETOR (OP8)
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.
■ CHAIN BRAKE
The chain brake is a device designed to stop the
saw chain quickly when kickback occured.
The brake system equipped on the G3100T units is
designed to work automatically by sensing reaction
force. It can also be activated manually by pushing
the brake lever (front hand guard) down forward.
A yellow cone popping up from the base of the
brake lever indicates that the brake is on.
Releasing the Brake
Pull the brake lever up toward the front handle until
it clicks. (OP9)
