Patent ID: 8505649

Claim:
A power tool comprising: a driven member that is operable to grip and drive at least one working element; a trigger; a mode selector movable between a first position defined as a working mode and a second position defined as an adjustment mode; drive means operable to drive the driven member about an axis, in the working mode to enable the working element to perform work, and the drive means operable to drive the driven member relative to the axis in the adjustment mode to enable the working element to be alternatively gripped or released by the driven member; mechanical torque control means alone controlling the torque transmitted from the drive means to the driven member, the mechanical torque control means including a plurality of torque control settings wherein the mechanical torque control means is operable to render the drive means inoperable to drive the driven member when the torque exceeds a pre-determined level, wherein each torque control setting corresponds to a different pre-determined torque level; the mechanical torque control means having an adjustment setting whereby the adjustment setting corresponds to a predetermined level of torque in the adjustment mode that is lower than a highest predetermined level of torque available in the work mode.
