It's extremely easy to adjust. You need something like a 17mm wrench on one side and a 24mm on the other, if memory serves (or a 12" crescent wrench if you're like most of us). Loosen the main through bolt with these wrenches, then turn the labeled cams to get your tension right. Then tighten. That will make more sense when you're looking at it, but the instructions in the owner's manual are pretty decent, if I remember correctly.
