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
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.

Storing the Machine

For periods of 3 months or longer
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 Clean the cutting blades, check
condition and spray with STIHL
resin solvent.
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, high or
locked location. Out of the reach of
children and other unauthorized
persons.
