Sharpening Instructions English / USA Storing the Machine : When the starter rope is fully extended it must still be possible to rotate the rotor another half turn. If this is not the case, the spring is overtensioned and could break. Take one turn of rope off the rotor in such a case. : Fit the starter cover on the housing. : Tighten down the screws firmly. The blades must be resharpened if cutting performance and behavior begin to deteriorate (i.e. if blades frequently snag on branches). It is best to have the cutting blades resharpened by a specialist on a workshop sharpener. STIHL recommends you have this work performed by a STIHL servicing dealer. It is also possible to use a flat crosscut sharpening file. See "Specifications" for prescribed sharpening angle. : Always file towards the cutting edge. : The file only sharpens on the forward stroke - lift it off the blade on the backstroke. : Use a whetstone to remove burr from cutting edge. : Remove as little material as possible. : After sharpening, clean filing or grinding dust off the cutting blades and spray 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. For periods of about 3 months or longer: : Drain and clean the fuel tank in a well ventilated area. : Dispose of remaining fuel and cleaning solution properly in accordance with local environmental requirements. : Run engine until carburetor is dry - this helps prevent carburetor diaphragms sticking together. : Clean the cutting blades, check condition and spray with STIHL resin solvent. : Fit the blade scabbard : Thoroughly clean the machine - pay special attention to the cylinder fins and air filter. : Store the machine in a dry, high or locked location - out of the reach of children and other unauthorized persons.
