Abstract:
1. A method of using a shears, the shears comprising: a body including a fixed jaw; a first movable jaw that pivots with respect to the fixed jaw; a hydraulic cylinder for actuating the first movable jaw to pivot; a main shaft for pivotally mounting the first movable jaw to the body; a rotational coupler that couples the main shaft for rotation with the first movable jaw without axially fixing the main shaft to the first movable jaw; and a removable stop assembly constructed and arranged to limit axial movement between the main shaft and the first movable jaw, the method comprising: detaching the first movable jaw from the shears; and replacing the first movable jaw with a second movable jaw, the second movable jaw having at least one different physical characteristic from the first movable jaw wherein before said detaching of the first movable jaw from the shears, the rotational coupler prevents the main shaft from rotating relative to the first movable jaw.
