Does this have self leveling tilt with the push button on the tilt lever ****? Also, how about the height sensor switch on the top of the mast channels? I know there is a solenoid on the control valve that can shut off the tilt when SAS kicks in or the self leveler senses forks are level with the button pushed and the sensor on the right tilt cylinder senses the mast is level. Just some ideas, it's a very complicated system.
