12.8 Sharpening the blades
● Removing the blade discs. (Ö 12.3)
● Remove the blade. (Ö 12.7)
Sharpening angle:
The sharpening angle for all the blades is
30°.
Instructions for sharpening the blades:
The following points must be observed
when re-sharpening the blades:
● Cool the blades when sharpening,
e.g. with water. The blade must not be
allowed to display blue colouring, as
this would reduce its cutting quality.
● Sharpen the blade 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.
● Re-sharpen the cutting edges to the
specified sharpening angle.
● Sharpen the blades against the cutting
edge.
Risk of injury:
Always wear thick
gloves.
When the blades are blunt, we
recommend that you reverse all the
blades on the particular blade disc.
All blades (regardless of the blade
geometry) are reversed in the same
way.
Risk of injury:
To prevent injuries, always clamp
down the blade discs before
installing or removing the blades.

There must be no gap between the
two blades (8) following installation.
A gap between the two blades
impairs the feeding function.
We recommend that all blades are
sharpened only by a specialist
dealer, as the function (drawing in
of shredding material, durability of
the cutting edges etc.) of the
garden shredder may deteriorate if
blades are ground incorrectly
(wrong sharpening angle,
imbalanced due to unevenly ground
blades etc.).
Always wear safety glasses when
sharpening. Make sure that others
are kept out of the danger area.
