- Twist the belt to assist in putting the clamp on.
- Push through the adjusting screw all the way through the bottom clamp.
- Place the other bottom clamp on the adjusting screw.
- Put the nut on the adjusting screw a few turns and slide the free clamp up against it.

Over tightening makes it harder to move the extruder so test it still moves freely after tightening.
