9DFiles and how to work with themSharpen using a special file holder with a saw chain round filedia. 4.0 mm. Normal round files are not appropriate for this work.See „Accessories“ for the order number.The file should cut only when pushed forwards (arrow). Lift thefile when leading it backwards.First sharpen the shortest cutter. The length of this cutter is thenthe standerd for all other cutters of the chain.Always guide the file horizontally (90° to the guide bar).EThe file holder makes file guidance easier. It is marked for thecorrect 30° sharpening angle (keep the marks parallel with thechain when filing, see illustration) and limits the cut depth tothe correct 4/5 of the file diameter. See „Accessories“ for theorder number.4/530°FAfter having sharpened the chain, the height of the depth limitermust be checked by means of a chain gauge. See „Accessories“for the order number.Correct even the smallest excess height (13) with a specialflat file. See „Accessories“ for the order number.Round off the front of the depth limiter (14).1314
