3.1 Nexo cordless Wi-Fi nutrunner
The Nexo cordless Wi-Fi nutrunner is designed for tightening operations of category A according to VDI
2862 that are critical in terms of safety. Results are stored and output, thus ensuring complete documen-
tation of any information that is relevant for tightening.
The control and power electronics are fully integrated in the nutrunner. In each working step, the integrat-
ed controller monitors the tightening operation and initiates wireless transmission of the results to the ex-
isting network. In case of radio shadows, the data are buffered. Once the connection to the network is
established, the data are transferred.
The graphical display on the nutrunner directly shows the tightening results to the user, irrespective of the
their position and the radio connection.
The Nexo cordless Wi-Fi nutrunner is supplied with energy by a slide-in battery pack. Power supply is
maintained for the buffer period when the battery is changed during operation (see page 45).
For further operating instructions and a description of the components, refer to the "Nexo" operating in-
structions that are supplied with the device.
