Heidelberg SM52

[DonnaS]

Hi! I have a Speedmaster 52 - 2 which has been running well. It has stood for about a week and now there is air blowing out where it's supposed to suck up the paper!

We have checked our electricity supply (they have swopped the phases before) but the problem is not there, and we have checked out the compressor etc and it is blowing and sucking where it is supposed to. But it's doing the wrong thing at the actual point its supposed to suck.

Any ideas?

Thanks!

has the feeder head been apart for cleaning or repairs?

maintains the suction head, blow into the pipes, check the solenoid valve at the C.E margin if it is not dirty.

Check the hoses that go to the feeder head.
They are probably cracked by age, oil and grease.

Radial valve in suction head.
