I have a Dewalt Power Drill DEWALT DCD708B ATOMIC. Instruction manual here.
What is the proper way to change a drill bit? I see many online videos, where they remove the battery, open the chuck hole manully with hand, and then retwist to tighten manually. In other articles, they use the battery to automatically open, and then auto retighten with the trigger. For my particular drill, it does not mention in the directions, and trying to figure out.
