Printmaster 46-2

Anybody familiar with how the vacuum is activated when you hit the production button on a PM46?
Press goes through its cycle of damps dropping, inkers dropping, blower activating, but no vacuum.
Not sure if it's a board issue or some sort of solenoid. Also, will not activate when setting the sheet thickness/length.

Hi sir

You need to check the pneumatic wiring to see what happens

I had the same problem.
I disassembled and rebuilt the vacuum compressor, freed the stuck vanes, and ordered and replaced the graphite inserts — it started working again.
