About the only way to check is to put a gauge on the Aux valve or plug up an implement to see if it works. The lever is two position so if you move the lever forward one valve is energized, move it back and the other one works. Let the juice set a while, add more, try to move it but not too much pressure. It's probably just seized up from no use. BTW it has a "cut-off" feature that will kick the lever to 'neutral' when you reach the end of the cylider movement, as when using a wheel type harrow, BTDT too many times.
