the tilt sensor is normally located on the base unit (turntable) inside the access doors, maybe on the hyd tank side. They are usually a cylindrical looking device mounted on a 3 spring pedistal. It will have a glass/clear top bubble indicator on top of it.
As for the 2nd (high) speed?
ANY boom or sizzor lift will not operate in high speed unless it is fully stowed away. If it is fully stowed then you have a switch malfunctioning.
