Throttle trigger lockout
The throttle trigger lockout prevents accidental operation
of the throttle trigger. If you put your hand around
the handle and push the throttle trigger lockout (A),
it releases the throttle trigger (B). If you release the
handle, the throttle trigger and the throttle trigger lockout
move back to their initial positions. This function locks
the throttle trigger at idle speed.
