11 Storing the Machine
For periods of 3 months or longer
► Drain and clean the fuel tank in a well ventila‐
ted area.
► Dispose of fuel properly in accordance with
local environmental requirements.
► Run the engine until the carburetor is dry – this
helps prevent the carburetor diaphragms stick‐
ing 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.
12 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 a 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 – 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.
