Patent abstract
A chainsaw has a cam lever and cam assembly that can be used to adjust the tension of a guide bar in the chainsaw. Once the tension of the guide bar has been lessened, the guide bar can be moved back and forth by using a chain-tightening knob and tightening mechanism. The movement of the guide bar causes the chain to tighten or loosen on the guide bar.
