So, the Dyna DM4400m uses a different presser assembly for the spindle than the SKIP based DM4400. The 'm' is based on hydraulics and I think the SKIP is a mechanical presser. Anyhow, I was curious if anyone knows the proper oil for the presser. I thought I would ask before I find some generic hydraulic oil. Or, perhaps, you just use the same Vactra 2 that you use on the way oiler????
