17 Sharpening Instructions

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 an authorized STIHL servicing
dealer.
It is also possible to use a flat crosscut sharpen‐
ing file. Hold the sharpening file at the prescribed
angle (see "Specifications").
► Only sharpen the cutting edge.
► 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
edges.
► Remove as little material as possible.
► After sharpening, clean away filing or grinding
dust and then spray the cutting blades with
STIHL resin solvent.
