Internal switch in a AS196 twin cylinder compressor?

Is there an internal switch in a AS196 twin cylinder compressor (capacitors)


I've replaced the POWER ON/OF switch, not sure about the capacitors. When switch on the motor hums and tries to turn very slowly but doesn't do a full revolution. My son got the AS196 from his works because it was not working. The unit was tested in 2014 and passed.

Nice little machine!

Well, yes there is a pressure switch.
Do you have the manual? Get it here:

But you should check item 33, condenser (AKA capacitor).

If that's OK, then, if it still has trouble starting, check item 45, "none return valve".

Most likely one or both those are the problem.

Let us know, and good luck.
