Two switches are necessary to start the spindle. Turn one to high or low and at the same time turn the second one to enable.
High or low reverses rotation in case you are in back gear.
There is the outside chance that the float switch in the way oil tank could be stuck or bad.
a wire could be broken, etc. need to follow a schematic with a meter.
