Raise or lower the taps as needed to put in neutral position.
Look up to the position indicator. Some people call this the clock since it looks like the face of a normal clock. If the indicator shows that the taps are raised then you will need to move the switch to the lower position and hold it. You will hear the regulator motor begin to operate and move the internal contacts. The indicator will slowly move towards the neutral position. If the indicator is in the lower position you will need to move the switch to raise. © 2018 Iowa Association of Electric Cooperatives

Confirm neutral by the indicator and the light.
Once the regulator is in the neutral position you can release the switch. The dial on the indicator should be in the neutral position and the neutral indicator light should be lit up. Always use two methods to confirm the regulator is in neutral. © 2018 Iowa Association of Electric Cooperatives
