Blade Maintenance - Viking GE 103 Manuel D'utilisation

11.4 Locking the blade disc
The locking device must always be
tilted back and secured with the
bolt after installation of the blade
disc and before operating the
machine again (see illustration).
● Remove the feed chute. (
● Loosen the screw (1).
● Turn the blade disc until the recess is
located in front of the locking device (2).
● Insert the locking device (2) in the
recess.
● Tighten the screw slightly (1).

11.5 Blade maintenance

Maintenance interval:
Before each use
● Remove the feed chute. (
● Lock the blade disc. (
● 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. VIKING
recommends VIKING specialist
dealers.
1 Reversible blades
● On the blades, measure the
distance (A) between the bore and the
edge of the blade at several points.
Minimum distance 6 mm

2 Wing blade
● Measure the blade width (B) at the
17 upward-pointing curved edge of the
wing blade.
Minimum blade width 18 mm
Removing the blade set:
● Lock the blade disc. (
11.2)
● Loosen the screw (1).
● Remove the screw (1), wing blade (2)
and blade disc (3).

11.4)
The specified tightening torque
must always be observed, as the
secure attachment of the cutting
tool depends upon it.
11.4)
Blunt shredding blades result in
deteriorating shredder
performance. A blunt reversible
blades can therefore be reversed
once.
● Reverse blade (6) and place onto the
blade disc with the sharp edge exposed
and align the bores.
● Insert screws (4) through the bores and
screw on nuts (5). Tighten the nuts (5)
to 10 Nm.
Sharpening the blades:
Blades which are blunt on both sides must
be sharpened before resuming work.
In order to ensure optimum machine
operation, the blades should only be
sharpened by a technician. VIKING
recommends VIKING specialist dealers.
● Remove the blades for sharpening.
● 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
11.4)
blades have reached the wear limits.
● Sharpen blades at a sharpening angle
of 30°.
● Sharpen the blades against the cutting
edge.
● After sharpening, remove any
sharpening burr at the cutting edge
using fine sandpaper.
● Observe the tightening torques
contained in the "Reversing the blades"
section when installing the blades.
