I just bought a Delta benchtop ROS at a garage sale and have a few
questions.

1) It came with hook/loop and SA sandpaper. The h/l is obvious, but how do
you use the SA? Do you have to pull the hook pad off, and then raise the
height to adjust for the thinner material? Sadly, no instructions came with
it.

2) It does oscillate, but it mainly spins around counterclockwise. My
handheld ROS don't spin like that; it is supposed to do that?

Any advice in general would be appreciated.
