A portable power wrench of an angle type includes an elongated housing with an angle drive head and a rear handle and supports a motor. The power wrench also includes a manually operated power control device including a main power control trigger located at the rear handle and an auxiliary power control trigger located at the angle drive head. The motor as well as the main trigger and the auxiliary power control trigger are connected to a programmable control unit in which there are stored operation parameter sets suitable for a screw joint running down phase and a final tightening phase, respectively. The auxiliary power control trigger is arranged to activate the running down parameter set only, whereas the main power control trigger is arranged to activate the final tightening parameter set.

A power tool comprises a housing () with an output shaft () driven by a rotation motor and an angle drive () connecting the output shaft () to the motor, wherein the angle drive () comprises a drive spindle () connected to the motor and carrying a pinion (), and a bevel gear () secured to the output shaft (). The drive spindle () and the pinion () are supported in the housing () via a ball type thrust bearing () having in one of its embodiments an inner ring () with a thread for cooperation with a threaded portion () on the drive spindle (), and an outer ring () which is rigidly secured in the housing (). The inner ring () is adjustable and lockable relative to the drive spindle, () by an annular lock element (). In an alternative embodiment the inner ring () is secured to the drive spindle (), whereas the outer ring () is threaded into a threaded portion of housing () such that the outer ring (), the drive spindle () and the pinion () are adjustable relative to the housing () and the bevel gear (). A deformable lock element () the outer ring () in set position.

A power tool system includes a portable power tool (), a stationary control unit (), and a cable assembly (), which includes a multi-core cableand connection pieces (), for communicating power and/or signals between the power tool () and the control unit (). The cable assembly () is provided with an electronic memory module in the form a data chip () for storing data relating to the identity and operation characteristics of the cable assembly () as well as data concerning the compatibility of the power tool (), the control unit () and the cable assembly (). The data chip is arranged to register and accumulate the number power tool operations performed via the cable assembly () and to indicate when a predetermined limit for power tool operations as regards mechanical wear of the cable assembly () is reached.
