grease for drill

[p8ntblr]

I have a Dewalt XRP 18V drill and the knob (behind the key less chuck) to change the power settings was stuck. I opened it up and noticed there was some grease on it along with a bit of saw dust. Do you know what type they use? I cleaned up the saw dust put it back together and it seems to be workingfine but was wondering if I need to add any grease?

I would think that white lithium grease would work fine.

When I had my DeWalt cordless open, the grease looked like molybdenum wheel bearing grease, but lithium or even petroleum jelly should be fine.
