26MAINTENANCESharpening the saw chainCAUTION: Before doing any work on the guide bar orchain, always switch off the engine and pull the plug capoff the spark plug (see "Replacing the spark plug"). Al-ways wear protective gloves!The chain needs sharpening when:The sawdust produced when sawing damp wood lookslike wood flour.The chain penetrates the wood only under great pressure.The cutting edge is visibly damaged.The saw is pulled to the left or right when sawing. This is causedby uneven sharpening of the chain.Important: Sharpen frequently, but without removing toomuch metal!Generally, 2 or 3 strokes of the file will be enough.Have the chain resharpened at a service center when you havealready sharpened it yourself several times.STOPAProper sharpening:CAUTION: Use only chains and guide bars designed forthis saw (see the Extract from the spare-parts list)!All cutters must be of the same length (dimension a). Cutterswith different lengths result in rough running of the chain andcan cause cracks in the chain.Minimum cutter length is 0.11" (3 mm). Do not resharpen thechain when the minimum cutter length has beenreached; at this point, the chain must be replaced (see theExtract from the spare-parts list and "Replacing the chain").The depth of the cut is determined by the difference in heightbetween the depth limiter (round nose) and the cutting edge.The best results are obtained with the depth-limiter depth of.025" (0.65 mm).CAUTION:Excessive depth increasesthe risk of kickback!Bmin.3 mm (0.11”)All cutters must be sharpened to the same angle, 30°. Differentangles result in a roughly, irregularly running chain, increasewear and tear and cause chain breakage.The 85° front rake of the cutter results from the cut depthof the round file. If the proper file is used in the right manner, thecorrect front rake will be obtained automatically.C.025"(0.65 mm).025"(0.65 mm)
