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 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 blade widths should be measured
at two or three points along the cutting
edges.
Use the smallest value.
Minimum blade widths (C, D)
Shredding blades (3):
C = 23 mm
D =
1 6 mm
11 .9 Sharpening shredding blades
● Remove the blade set. ( Ö 11.6)
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 visible 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.
11 . 1 0 Electric motor and wheels
The electric motor is maintenance-free.
The wheel bearings are maintenance-free.
11 . 11 Storage and winter break
Store the machine in a dry and locked
place that is generally free of dust. Make
sure that it is kept out of the reach of
children.
Always store the machine in good
operational condition.
Keep all nuts, pins and bolts tightly
fastened, replace danger signs and
warnings on the machine that have
become illegible, check the entire machine
for wear and damage. Replace all worn or
damaged parts.
Any machine faults must be completely
remedied prior to storage.
Note the following points when storing the
machine for long periods (winter break):
● Clean all external parts of the machine
with care.
● Thoroughly lubricate/grease all moving
parts.
The measurement procedure and
the value specified are the same for
all three wing blades.
Asymmetrical wear may occur at
the wing blades due to uneven use
of the cutting edges.
The measurement procedure and
the value specified are the same for
both shredding blades.
Asymmetrical wear may occur at
the shredding blades due to uneven
use of the cutting edges.
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.
