English Storing the Machine Sharpening Instructions For periods of 3 months or longer N Clean the cutting blades, check condition and spray them with STIHL resin solvent. N Drain and clean the fuel tank in a well ventilated area. N Dispose of fuel properly in accordance with local environmental requirements. N Run the engine until the carburetor is dry - this helps prevent the carburetor diaphragms sticking together. N Fit the blade scabbard. N Thoroughly clean the machine - pay special attention to the cylinder fins and air filter. N Store the machine in a dry and safe location (use the ring integrated in the rear handle) - out of the reach of children and other unauthorized persons. When cutting performance and behavior begin to deteriorate, i.e. blades frequently snag on branches: Resharpen the cutting blades. It is best to have the cutting blades resharpened by a dealer on a workshop sharpener. STIHL recommends a STIHL servicing dealer. It is also possible to use a flat crosscut sharpening file. Hold the sharpening file at the prescribed angle (see "Specifications"). N Only sharpen the cutting edge - do not file blunt projecting parts of the cutting blade or the cutting blade guard (see "Main Parts and Controls") N Always file towards the cutting edge. N The file only sharpens on the forward stroke - lift it off the blade on the backstroke. N Use a whetstone to remove burr from cutting edge. N Remove as little material as possible. N After sharpening, clean away filing or grinding dust and then spray the cutting blades with STIHL resin solvent. Do not operate your machine with dull or damaged cutting blades. This may cause overload and will give unsatisfactory cutting results. 20 HS 46, HS 46 C, HS 56 C
