Pulleys and drive belts:
•
Please check the correct seating of the 3 belts and two pulleys before operating the mulcher and before
attaching the pulley guard.
•
The alignment of the upper and lower pulley must be absolutely vertical to avoid wear and malfunctioning.
Figure 23 below shows the correct pulley alignment. The pulleys must be vertically aligned, i.e. they must be
vertically parallel above each other.
•
The correct pulley alignment is adjusted via the:
-
Shaft guide (Figure 20)
-
Tensioning device (Figure 21)
-
Transmission mounting (Figure 22)
For details on adjusting the pulley alignment, please refer to the "Commissioning" section of these operating
instructions.
The drive belt tension is also adjusted via the shaft guide, tensioning device and transmission mounting.
