What happens when you have a pad on and is flat on paint? Does it still rock?

I love Rupes pads especially the yellow. But I can pretty much get my mk2 to work with any pad product combo while keeping the smoothness of the machine in tact.
Possibly try lowering the speed.
I can't stand the Rupes blue pads myself. No matter what I do I always wind up with sling. I use Meg's microfiber cutting pads to get the job done with zero sling.
Sounds like you may have a bad unit. Contact Rupes directly to confirm. They have outstanding customer service.
The back to back motion is a function of the oscillation and the soft start. Until enough torque is available to the pad to break it loose (think a drag car and traction) the tool will drive against you. It is usually very very minor and noticeable for a split second...
However, if the shroud has worn, it could lock against the backing plate (again until enough torque is available to override it) which will only increase the initial steering.
The function of the shroud is to limit pad rotation in free air. When the pad is applied to the paint and the forces that induce rotation are increased, a properly lubricated shroud will become almost invisible.
As far as which lubricant to use you have a few options.
1) Pneumatic Tool Oil or similar. This is what we (RUPES Technical and Sales Team) use the most because we always have some handy.
2) Dielectric Grease - This is similar to what is applied at the factory and will last the longest.
3) Vaseline or similar - Will last nearly as long as the grease but might not provide quite the slip of the grease or oil.
Thanks for chiming in Todd!

Is the backing plate spinning flat? Somehow my backing plate was wobbling one day( it was tight) so i ordered a new one and it stopped. Maybe look into that and possibly purchase a new backing plate.
