90° N Guide the file: horizontally (at a right angle to the side surface of the guide bar) in accordance with the specified angle - according to the markings on the file holder - rest the file holder on the tooth head and the depth gauge N File only from the inside outward N The file only sharpens on the forward stroke - lift the file on the backstroke N Do not file tie straps and drive links N Rotate the file a little periodically in order to avoid uneven wear N To remove file burr, use a piece of hardwood N Check angle with file gauge All cutters must be equally long. 689BA043 KN 689BA018 KN With varying cutter lengths, the cutter heights also vary and cause rough running of the saw chain and chain breakage. N All cutters must be filed down equal to the length of the shortest cutter - ideally, one should have this done in the workshop using an electric sharpener Depth gauge setting a 689BA023 KN The depth gauge determines the depth to which the cutter penetrates the wood and thus the chip thickness. a Required distance between depth gauge and cutting edge When cutting softwood outside of the frost season, the distance can be increased by up to 0.2 mm (0.008"). Chain pitch Inches 1/4 P (mm) (6.35) Depth gauge Distance (a) mm (Inches) 0.45 (0.018) Lowering the depth gauges The depth gauge setting is lowered when the cutter is sharpened. English N Check the depth gauge setting after each sharpening 1 N Lay the appropriate file gauge (1) for the chain pitch on the saw chain and press it against the cutter to be checked - if the depth gauge protrudes past the file gauge, the depth gauge must be reworked N Rework the depth gauge so that it is flush with the file gauge N Afterwards, dress the leading edge of the depth gauge parallel to the service mark (see arrow) - when 689BA044 KN 689BA051 KN 689BA047 KN MSA 160 C, MSA 200 C 43
