Rotex RO150 Pad Wobble Question

[Skellyy]

Hey all, quick question on my Rotex 150.  I've been sanding my deck and all has been going well.

Using it today, and all of a sudden it felt like the sanding pad was loose.  So I shut the sander off, and there is some rotational slop in the pad (while in rotex mode).  I get about a 1/4'' wiggle if I rotate the pad back and forth before the rotex gears engage.

Is this normal or am I going insane?

Thanks

When you're in Rotex mode, the path is not truly round like a real orbital sander. There is some wiggle by design.
