Anyone else have problems turning the adjustment wheels on the Pro Flesher? I'm trying to adjust the left guard backwards so I can expose more blade. I loosen the bolt, then turn the adjustment wheel. At first they didn't want to turn at all, then I took a rag and gripped against them (so I wouldn't rip my finger skin off) and it moved a wee bit but barely. This machine is new, never been used (I know someone said that flesh and dirt can build up in them and made it hard to turn ... but that is obviously not what happened ) I heard such great things about this "micro adjustment" system and it looks like it would work great .. if I could get the adjustment wheels to turn freely. I know they shouldn't be this hard to turn!! I tried oiling them with some WD-40. Any suggestions? I'm wondering if they weren't deburred well and there might be something holding it up in there. If I can get it loose enough I'll try to take the whole adjustment system apart, so I can inspect it and oil it.
