If it is 40T then if you follow the smaller airline going to the right it will lead you to a regulator. Net to the regulator is a manifold with a couple of solenoids mounted to it. If your facing the back of the machine the solenoid on the left is the pre-charge.
First you'll need to remove the small air line and see if your piston retracts correctly.
If your switch is all out of adjustment, your switches and tool release piston are not set up correctly and you could end up ripping your tool changer off or crashing due to tools hanging up in the spindle. Be carefully.

Loose Nut,
I found the snap ring from on top of the piston spring was cupped and finally busted off. This was the reason the unclamp (lower) switch was not getting a proper contact. I installed a new snap ring and removed the switch shim, and all was fine for 3 days. Now, I have am seeing a new symptom. When I push the tool unclamp button(s), I am not seeing a proper pre-chage, but rather a full blast of air coming through the spindle.
This is making it hard to insert a tool holder into the spindle. I am going to try to inspect the solenoid today. Maybe it has a frozen contact or spool??? Any other ideas?
