Hi

Anybody have any documents on the GRAM HC series?
Have a Gram HC 8075 from 1995 running a Svalbard icemachine, where the compressor loses oil pressure when i start the icemachine cycle. Starts at 2-2,5 bars, but drops to 0,5-1 bar after a couple of cycles.

Have no documents on icemachine either if anybody has that, Svalbard D16-R22

Has been overhauled, but has been sitting for approximately 2 years now. Uncertain if overhaul was done correctly/thouroughly.
