Thanks for taking the time to review my problem. I currently looking into a Milltronics Partner I 1988. The device has a couple of problems, a secondary monitor is utilized because the original is burned out, the tool changer is not functioning: the air piston does not engage the half moon slot located under the pulleys.
Question: Is there any electronically available manuals I might get a hold of for electronic, mechanical and pneumatic repairs?
Question: What powers the pneumatics, is it self generated or does this machine need to be connected to an air supply?

Thank you for your expertise
