This exercise is much better than evening english classes! ;-)
I copied your sentence from the first message and I thought to have learnt a new verb: "to wedge" as a synonym for to pry!
By the way the action is not similar to a wedge as the two parts of the clamps for small movements (2 to 10 mm) are parallel and the risk of damaging the case is actually zero.
Will scan and post the Techworks user manual for the accelerator to see how they describe the thing.
