How do I safely install the DeWalt DW1710 drill bit into my drill?

First, ensure your drill is unplugged or the battery pack is removed to prevent accidental startup. Open the drill chuck jaws by rotating the chuck collar counter-clockwise, then insert the bit shank as deeply as possible without touching the back of the chuck. Tighten the chuck jaws firmly by rotating the collar clockwise, using the chuck key to tighten all three holes on keyed chucks for maximum grip. Verify the bit is centered and securely held by gently pulling on it.
