Maintenance and care
5.6.2 Changing the V-belts
The V-belts should and/or have to be replaced, when
further tensioning is no more possible and when they
are damaged (frayed, porous, …).
WARNING!
Danger of crushing! Take care of your
hands and fingers when exchanging the
V-belts!
NOTE
The V-belts should be changed simultaneously in
order to ensure even tension and power transmit-
tance!
The V-belts of the cutting shaft are changed as follows:
– Loosen the 4 fixing screws at the V-belt cover (fig.
5.3).

– Remove the V-belt cover (fig. 5.4).
– Release tension of the V-belts until they can be re-
moved without any force (refer to section 5.6.1).
Fig. 5.4
NOTE
Move the cutting shaft pulleys and the V-belt
pulleys a bit towards each other as the new
V-belts have not yet been elongated.
– Apply the new V-belt
ATTENTION!
Do not use any sharp or pointed objects
for changing the V-belts in order to
prevent damages that might destroy the V-belts.
NOTE
Turn the pulleys of the cutting shaft and the motor
and move the V-belts diagonally across the pulley
grooves until all 3 V-belts are parallel.
– Tension the V-belts (refer to section 5.6.1).
ATTENTION!
Do not overstretch the V-belts (1,5 % wear
limit)! There is danger of the joint cutter’s
shaft bearing and engine’s mounting becoming
destroyed!
– Check the tension of the V-belts (refer to section
4.2.2).
– Mount the V-belt cover (fig. 5.4 and tighten all loos-
ened screws.
ATTENTION!
After commissioning the machine or after
replacing the V-belt, it has to be checked
after 10 operating hours and, if necessary, to be
re-tensioned.
