operating and maintenance instructions
contained in the accompanying engine
instruction manual.
The cooling ribs must always be kept clean
to ensure that the engine is adequately
cooled.
11.2 Cleaning the machine
Maintenance interval:
After each use
Clean the machine thoroughly each time it
has been used. Care of the machine will
protect it against damage and extend its
service life.
Cleaning position of the garden
shredder:
It is only permitted to clean the machine in
the position shown.
● Remove the feed chute. ( 7.8)
The machine (engine) may be damaged if
the garden shredder is not positioned as
described.
Never spray water onto
motor or engine components,
seals, bearing points or
electrical parts such as
switches. This would result in
expensive repairs.
If you are unable to remove
the dirt and accumulated
deposits with a brush, a damp
cloth or a stick, STIHL
recommends the use of a
special cleaner (e.g. STIHL special
cleaner).
Do not use aggressive cleaning agents.
Clean the blade discs regularly.

Remove dirt from the cooling ribs, fan
wheel, area around the air filter, exhaust,
etc. to ensure that the engine is
adequately cooled.
11.3 Blade maintenance
Risk of injury!
Always wear protective
17
gloves.
Maintenance interval:
Before each use
● Remove the feed chute. ( 7.8)
● Check the blades for damage (notches
or cracks) and wear; reverse or replace
if necessary.
Wear limits of the blades:
The blades must be reversed or
replaced before the specified wear
limits are reached. STIHL
recommends STIHL specialist
dealers.
● On the blades, measure the distance
between the bore to the edge of the
blade at several points.
Minimum distance 6 mm
Reversing the blades:
The cutting blades are designed as
reversible blades. This means that
blunt blades can be reversed and
the machine is ready for use again.
Always reverse both blades.
● Remove the blade disc. ( 7.6)
● Unscrew screws (1) and remove
together with nuts (2).
● Remove blade (3) upwards.
● Clean the blade disc.
● Reverse blade (3) and place onto the
blade disc with the sharp edge exposed
and align the bores.
● Insert screws (1) through the bores and
screw on nuts (2). Tighten nuts (2) to
22 - -28 Nm.
● Install the blade disc. ( 7.5)

Sharpening the blades:
Risk of injury!
It is recommended that the
sharpening of all shredding blades
be performed exclusively by a
specialist dealer. Blunt and
incorrectly ground blades (incorrect
sharpening angle, imbalance due to
unevenly ground blades, etc.)
increase the risk of kickback.
Shredding material kickback may
result in serious injury to the user.
In addition, the performance (intake
of the shredding material, stability
of the cutting edges, etc.) of the
garden shredder may deteriorate.
● Remove the blades for sharpening.
● Cool the blades when sharpening,
e.g. with water. The blades must not be
allowed to display blue colouring, as
this would reduce their cutting quality.
● Sharpen the blades evenly to prevent
vibrations due to imbalance.
● Check blades for damage before
installing: the blades must be replaced
if notches or cracks are visible or if the
blades have reached the wear limits.
● Sharpen blades at a sharpening angle
of 30°.
● Sharpen the blades against the cutting
edge.
