Abstract
A power tool includes a leveling device which includes a rotatable member which seeks an equilibrium position which corresponds to a level position. A rotating device includes a member which enables passage of a beam. An electrical circuit which includes an emitting device, a receiving device and an indicating device is electrically coupled such that upon activation, the emitting device emits a beam which passes through the beam passing member. The beam is received by the receiving device which, in turn, activates the indicator device. The indicator is generally a light emitting device which has a varying brightness so that the user may view the indicator from all sides of the power tool.
