Storing the Machine

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.

Sharpening Instructions

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 lubricate with grease.
Do not operate your machine with
dull or damaged cutting blades.
This may cause overload and will
give unsatisfactory cutting results.
