11.9 Sharpening shredding blades

We recommend that all shredding
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, imbalance due to unevenly
ground blades etc.).
● Remove the blade set. (
Sharpening angle:
The sharpening angle for all shredding
blades is 30°.
Instructions for sharpening the
shredding blades:
The following points must be observed
when re-sharpening the shredding 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 noticeable or if
the blades have reached the wear
limits.
● Re-sharpen the cutting edges to the
specified cutting angle.
● Sharpen the blades against the cutting
edge.

2 Combination blade
● Hold a ruler (5) against the reference
edge (4) of the combination blade.
The distance (A) between the cutting
edge and the ruler indicates the wear.
Maximum wear limit (A) for combination
blade (1):
A = 5 mm
3 Wing blade
The measurement procedure and
the value specified is the same for
all three wing blades.
Asymmetrical wear may occur at
the wing blades due to uneven use
of the cutting edges.
● The blade width should be measured at
two or three points along the cutting
edge.
Use the smallest value.
Minimum blade width (B)
Wing blade (2):
B = 40 mm
4 Shredding blades
The measurement procedure and
20
the value specified is the same for
both shredding blades.
Asymmetrical wear may occur at

at two or three points along the cutting
edges.
Use the smallest value.
