I own a hammer drill (DeWalt d25263). I was using it today, and everything went well. But as I removed the SDS chisel bit that I was using, I saw a good bit of grease on the shank of the bit. I've never seen this before.
I'm worried that the tool has been compromised. The instructions say to take the drill to a repair shop to have it cleaned and lubricated after use. I would like to know how to lubricate it.
I looked for videos on YouTube but didn't find anything that was helpful. Can you please tell me how to lubricate a hammer drill?
