28ααββSTOPABmin.3 mm (0.11î)CThe sharpening angle (α) must be identical for all cutters!25∞ for chain type 486, 496The teeth will have the proper angle (β) automatically if theproper round file is used.60∞ for chain type 486, 496Different angles result in a roughly, irregularly running chain,increase wear and tear and cause chain beakage.MAINTENANCESharpening 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"). Alwayswear protective gloves!The chain needs sharpening when:The sawdust produced when sawing damp wood looks likewood 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.Proper 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.The minimum cutter length: 0.11" (3 mm). Do not resharpen thechain when the minimum cutter length has been reached; atthis point, the chain must be replaced (see the Extract from thespare-parts list and "Replacing the saw 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 a depth-limiter depth of .025"(0.65 mm).CAUTION: Excessive depthincreases the risk of kickback!.025"(0.65 mm).025"(0.65 mm)
