  • The chuck screw is reverse threaded, which means you will need to unscrew it counterclockwise.

Although you specify "reverse threaded", you confuse the issue by saying "counterclockwise." You mean counterclockwise from the drill's perspective, but that's counter-intuitive. Many folks will assume clockwise or counter from the screwdriver's perspective. It would help to make that clear. Same applies to step 3 where the photo makes it clear you mean clockwise from the drill's perspective, but since your're unscrewing the allen screw, I would tend to interpret it from the allen wrench's perspective, which would be counterclockwise. Thanks for providing this instruction set.
