Checking and Replacing the Chain Sprocket N Remove the chain sprocket cover, chain and guide bar. N Disengage the chain brake: Pull hand guard toward the front handle. Replace the chain sprocket - after using two saw chains or sooner - if the wear marks (arrows) on the sprocket are deeper than approx. 0.02 in (0.5 mm) since this would reduce the life of the chain. You can use a gauge (special accessory) to check the depth of the wear marks. It is best to use two saw chains in rotation with one sprocket.
