• Avoid touching the tie straps and drive links with the file. • Rotate the file at regular intervals while filing - this avoids one-sided wear. 689BA018 KN 90° • Use a piece of hardwood to remove burrs from cutting edge. • Check angles with the filing gauge. 689BA025 KN As these requirements can be met only after sufficient and constant practice: Use a file holder.* A file holder must be used for manual resharpening of Super chain. The correct filing angle is marked on the file holder. 689BA022 KN 85° 70° 90° 60° 80° 30° 35° 10° 0° For checking angles 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. File correctly • 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 two or three strokes of the file are 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 backstroke. • Hold the file horizontally for all chain types (at right angle to side of guide bar) and file according to the angles marked on the filing tool. All cutters must be the same length 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 an electric grinder. * Special accessory 45
