A convenient new feature provided with your drill is a level.
It is recessed in the motor housing on top of your drill. It
can be used to keep drill bit level during drilling operations.

Always wear safety goggles or safety glasses with
side shields when operating tool. Failure to do so
could result in objects being thrown into your eyes,
resulting in possible serious injury.
