More Information
Summary:The present invention is directed to a chain saw having a chain tension knob to adjust the tension of a chain. The knob is rotated to move the chain bar to increase or decrease the tension on the chain depending on the direction of rotation. The knob is positioned at a forward portion of the chainsaw housing, below the chain bar. The knob acts as a chain catcher so that in case of chain breakage or derailment, it blocks the chain from swinging rearward toward the user and reduces the likelihood of serious injury.
