# Socket release function

It is recommended to use the socket release function on all the ETP ST101 tools. When the function is enabled, the socket rotates backwards 3° after a completed tightening. The aim is to reduce tension on the reaction bar and to make it easier to remove the tool.

The socket release function is turned on from the controller.

On Power Focus 4000:

- Use the navigation buttons to follow the path > Pset > Programming+ > Options > Socket release > Mode On
