Speed Settings?

Just got a PC 7424 and need to know what number on speed setting switch corresponds to what RPM. Thanks!

Doesn't really matter...

If you need to remove swirls you're going to be on the 5.0 to 6.0 speed setting
For polishing after removing the swirls you want to be on the 4.0 to 5.0 speed setting
For applying a liquid finishing wax or paint sealant you want to be somewhere in the 3.0 to 4.0 range...

IF you're using a one-step cleaner/wax to remove defect then that would be like removing swirls so your back up to the 5.0 to 6.0 speed setting.

I've buffed out a zillion cars and never gave one thought about what the OPM or Oscillations Per Minute are while doing the work because you base your procedure on the speed setting on the dial and at that point it's kind of relative as to what the technical spec is for OPM, just spin the dial to the speed setting you want and get busy.

Actually good questions, but this thread shows the benefit to a limit to editing posts, you edited and changed your original post and had I not quoted you in my first answer, my answer wouldn't make sense because it would match your new post.

Regardless, my answer still stands, you're not going to go by the OPM in the manual, you're going to select, 3, 4, 5, or 6 on the dial depending upon what you want to do.
