Welcome to the Dewalt Hammer Drill DW511 lever assembly replacement guide. The lever assembly controls whether the drill is in hammer mode or normal drill mode. Over time, the lever assembly can become damaged and need replacement. A damaged lever assembly can become stuck and prevent the drill from running.
Caution should be taken when working with the drill. It needs to be unplugged before working on any part of it.
