B . for cracks in the links and damaged rivets - replace any damaged or worn parts of the chain and match the new parts to the shape and size of the original parts. . It is absolutely imperative to comply with the angles and dimensions specified below. If the . . - and in particular if the depth gauge is set too low - there is a risk of increased kickback of the chainsaw, with resulting . . . See “Technical Data” for the permitted chain pitches. The chain pitch (e.g. 3/8) is marked on the depth gauge side of each cutter. . Other files have the wrong shape and cut. Select file diameter according to chain pitch - see table at the end of this chapter. You must observe certain angles when resharpening the chain cutters . Filing angle .

Furthermore, the angles must be the same on all cutters. If angles are uneven: Chain will run roughly, not in a straight line, wear quickly and finally break. • Avoid touching the tie straps and drive links with the file. • Rotate the file at regular intervals while filing 689BA025 KN this avoids one-sided wear. 90° 689BA018 KN • Use a piece of hardwood to remove burrs from cutting edge. • Check angles with the filing gauge. As these requirements can be met only after sufficient and constant practice: !* A file holder must be used for manual resharpening of Super chain. The correct filing angle is marked on the file holder. $ STlHL filing gauge* (see table) A universal tool for checking the filing and side plate angles, depth gauge setting and cutter length. Also cleans the guide bar groove and oil inlet hole. 90° 60° 85° 70° 80° 0° 35° 10° 30° 689BA022 KN $ . • If you use a file holder or the FG 1: Leave the chain on the bar. • Clamp the bar in a vise if necessary. Lock the chain - push hand guard forward • • To rotate the chain - pull hand guard against front handle • Sharpen chain frequently, take away as little metal as possible . If the cutters are not the same length, they will have different heights. This makes the chain run roughly and can cause it to break. Find the shortest cutter and then file all other cutters back to the same length. This can be very time consuming - it is best to have it done in the workshop on two or three strokes of the file are an electric grinder. usually enough • Always file from the inside to the outside of the cutter. • The file only sharpens on the forward stroke lift the file off the cutter on the back stroke. • Hold the file % for all chain types (at right angle to side of guide bar) and file according to the angles marked on the filing tool. * Special accessory 689BA023 KN 689BA023 KN Chain Depth gauge pitch distance “” a Inch (mm) mm (Inch) 689BA024 KN Round off depth gauges parallel to the stamped marking. 1/4 (6.35) 0.65 (0.026) 3/8-PM (9.32) 0.65 (0.018) 3/8-PMN (9.32) 0.45 (0.026) 0.325 (8.25) 0.65 (0.026) 3/8 (9.32) 0.65 (0.026) 0.404 (10.26) 0.80 (0.031) ' . The depth gauge determines the height This setting may be increased by 0.2 mm at which the cutter enters the wood and thus the thickness of the chip removed.
