You could try tightening the bolts with the levers latched, but I am not sure if that would do much.
Also, the levers should take some force, but it shouldn't be a lot. If you can't lock them comfortable then there is something wrong. Also, just a general rule, when the allen wrench your using to tighten the bolts can just barely fit between the body and top it is properly spaced.
