You are completely wrong. If this is the Gauntlet you purchased from you know who the press should run extremely smooth and putting any kind of dampers under the feet would be a big mistake. You should hire a M&R technician to install the press properly to see how it's really supposed to work or continue wasting time and money as well as possibly causing expensive damage to your press. If you want the best results contact our service department and get it done right!
It's a Gauntlet and it clatters when the carousel lifts or has bounce back from the index shock. Very common and Very easy fix as the index and lift need to be fine tuned.
