RRS Anvil 30 Tension

[Jigstick]

Just received my Anvil-30. Is there a way to adjust how much tension the lever puts onto the ball? Mine goes from totally free flowing with no pressure to 100% locked down solid with about 1/2in of movement on the tension arm.

I knew there had to be a way. Thanks bro.
