We often get a message regarding the oscillation not working, over time the link bar can loosen and come away from the main spindel making your oscillation inoperative.
A simple fix is to slide the link bar back over the spindel and tighten it with a small allen key (usually 3/4mm). Make sure that the flat side of the spindel (keyway) is facing the allen key bolt so as it sits flush. This is a simple quick fix and will save you some money!
