How to Lubricate a Hammer/Rotary Drill

lubricationpowertools

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 clean and lubricate it myself.

I looked for videos on YouTube but didn't find anything that was helpful. Can you please tell me how to clean and lubricate a hammer drill?

Here's the relevant bit, which includes some liability tone:

Your tool was properly lubricated before leaving the factory. In from two to six months, depending upon use, take or send your tool to an authorized service center for a complete cleaning, inspection and lubrication. Tools used constantly on production jobs will need relubrication more often. Also, tools “out of service” for long periods should be relubricated before being put back to work.

The simple fact is that it doesn't need periodic lubrication for the casual user. It would be different if you were a professional drilling dozens of holes every day.

If you like, dab a little common grease in the chuck on occasion. There's a lot of slop (movement) in that type of chuck, and friction can heat things up if it's totally dry.
