Abstract:
1. A manually operable electrically powered tool, comprising: an electric motor disposed in a housing; a drive train disposed between the motor and a tool spindle, comprising: a gearbox coupled to the motor; a clutch for interrupting drive from the motor to the spindle when a predetermined torque is applied to the spindle, wherein the clutch comprises two components urged together by a spring such that a first component is held in a stationary position relative to a second component when a torque force applied to the spindle is less than a threshold spring force; an adjustment member for setting different modes of operation, the adjustment member being coupled to the clutch, the adjustment member being moveable between a first and Nth position such that, when the adjustment member is in the range of positions between the first and N−1 positions the tool is operable in a screw driving mode and the spring force applied to the clutch components can be varied, and, when the adjustment member is in the Nth position the tool is operable in a drilling mode and the clutch is inoperable; wherein the adjustment member comprises a rotatable collar with icons arranged on a surface thereof; wherein the housing includes a transparent portion which overlaps at least a portion of the surface on which the icons are arranged; wherein the adjustment member comprises a first circumferential portion and a second circumferential portion, the second circumferential portion being located closer to the motor than the first circumferential portion; and wherein the icons are arranged on the second circumferential portion.
