Stihl 036 Instruction Manual - Page 48

• Avoid touching the tie straps and • drive links with the file. Rotate the file at regular intervals while filing - 90° • this avoids one-sided wear. Use a piece of hardwood to remove • burrs from cutting edge. Check angles with the filing gauge. 689BA018 KN 689BA025 KN 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. 85° 70° 90° 60° 80° 30° 35° 10° 0° 689BA022 KN 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. • 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 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. 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
