Abstract
A saw having a power unit with a drive component and a housing for the power unit with a frame. A bar on the housing guides movement of an operatively positioned cutting chain driven by the drive component in an endless path. The bar is movable guidingly in opposite directions in a predetermined path relative to the housing to thereby vary tension upon an operatively positioned cutting chain. A bar fixing assembly has a knob that is turnable around a first axis relative to the housing in: a) a first direction to a tightened state; and b) a second direction to a loosened state. A first assembly resiliently bears against the knob to at least one of: a) inhibit turning of the knob around the first axis; b) provide a sensory indication to a user grasping and turning the knob that the knob is moving around the first axis; and c) reduce play in the knob.
