Hi, This is my first post. I recently bought a Vermeer BC1400, my first chipper. It sat around for a while before I bought it and I had to solve some problems to get it running and chipping. It does chip now! But, I brought it to a job and was chipping some pretty big stems, probably max capacity 14". Now, the (vertical) infeed rollers have about a 3" gap between them and I can't get them to spring together again. I tightened the springs to max tightness, and cleaned under the infeed rollers as best as I could. The machine still chips OK, but I would prefer the infeed rollers to be closed so they can grab small branches, and just to keep it in proper order. Can anyone help me with advice or troubleshooting tips? How do I tighten these rollers together again? Thanks!
