English Checking the Chain Sprocket N Disengage the chain brake: Pull the hand guard toward the front handle. N Remove the chain sprocket cover, chain and guide bar. 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. STIHL recommends the use of original STIHL sprockets to ensure correct operation of the chain brake. Have the chain sprocket replaced by a servicing dealer.
