► 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")
► 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 away filing or grinding
dust and then spray the cutting blades with
STIHL resin solvent.
NOTICE
Do not operate your machine with dull or dam‐
aged cutting blades. This may cause overload
and will give unsatisfactory cutting results.
