model H30D serial H2X393T01644. I received this Linde H30D diesel at no cost. Secured starter that was hanging by one bolt, installed a new battery. Unit fired up but had no travel. Come to find out, the potentiometer was taken out. Probably to use on another unit in their fleet. Installed a new one. Must this be calibrated by software? I have been a tech for 14 years but have never serviced a Linde. Seems to be a great machine. I am currently learning about the hydrostatics. Problem is it seems as though the "brakes" are dragging. I understand that upon acceleration the brakes are released and then applied when decelerating. It has single accel and brake pedal. Hopefully it is a simple service call for calibration.
