Levelling system

Abstract

A system includes a power tool that has a rotation output shaft for rotationally driving a levelling mechanism for a structural attachment and has a rotation drive mechanically connected to the rotation output shaft to rotationally drive the rotation output shaft. The system further includes a remote unit that has a first structural attachment contact structure where the first structural attachment contact structure is contactable with the structural attachment and where the remote unit is detached from the power tool. The system additionally includes a control arrangement that has an orientation device configured to provide orientation data relating to an orientation of the first structural attachment contact structure and has a drive controller which is connected to both the rotation drive and the orientation device where the drive controller is configured to influence action of the rotation drive in response to orientation data provided by the orientation device.
