You have to put mineral oil on the bar that the arm slides on otherwise it gets full of junk and stiffens up

I'm quite sure there is no sand or sand-like substance on the 2912. You could be seeing bits of corrosion falling out of the gauge plate. To remove the gauge plate, remove the two large plastic plugs on the back side and remove the two bolts with a 1/2" socket. with the gauge plate opened far enough to clear the knife, you should be able to remove the gauge plate and look for corrosion and attempt to clean it.

When reattaching the gauge plate, be certain to install it such that it doesn't hit the knife. Slip the gauge plate back on, then fully close the gauge plate. Install the bolts removed earlier, but not tight yet. As you gradually tighten the two bolts, position the gauge plate such that there is a small gap between the gauge plate and the knife with the gauge plate fully closed. Tighten the bolts and reinstall the plastic plugs.

Also, depending on you fine this "sand" is, could it simply be fine metal particles from sharpening the knife?
