# De-tensioning the nut

1. Turn back the tensioner by 3 mm from the face contact of flange.

2. Select Manual mode on the hand controller, then set pressure at which bolt was tensioned originally and start building pressure while holding the click wrench with positive force in counterclockwise direction.

3. When the applied load reaches break opening point, the click wrench moves freely opening the nut. Turn the click wrench 6-7 times its limited window cycle.

4. Release pressure and check that the bolt is loose.

Pressure trapped

The max stroke indicator on the puller bar should not be visible while pressuring the tensioner. If visible, stop and adjust the position of the puller bar on bolt so that the max position is not reached until the required pressure is achieved. Otherwise, if done repeatedly, it can physically damage the internal components of the tensioner.
