# Tightening

As the tightening torque increases, the reaction force builds up equally. Make sure that the tool is in correct working order and correctly programmed. Unexpected behavior from the tool may result in operator injury.

## Rotation Direction for the Tightening

Check that the tool is in the correct running direction by:

- Turning the reverse ring to the right to set the tightening direction to clockwise (CW).

- Turning the reverse ring to the left to set the tightening direction to counterclockwise (CCW).
