What exactly are you referring to? OP has a drum (if i'm not mistaken) machine. Are you referring to a crank (off topic)? If so, yes, you should be cleaning the gripper plates every so often, and making sure it's adjusted properly when you string. Don't go too crazy, though, there are ball bearings in many linear grippers that might not roll so well with cleaner residue on them.
