4. ADJUSTMENTS
REVERSE
The reverse function can be used at full rpm (1000 rpm on the PTO), but we
recommend you to reduce the rpm to relieve the machine as much as possible.

Fig. 4-19 The overlap between the steel friction disc B and the rubber disc C must be 5+/-
3mm. If the rubber disc is worn, the overlap is adjusted automatically by the electric
motor A, as it always presses with the same maximum pressure and thus ensures a
constant pressure between the two parts B and C.
CAUTION:
Only use the reverse function for short periods to ensure
correct functioning and long life of the rubber disc.

Fig. 4-20 The tightening of the V-belt drive is also adjusted automatically. It is determined by
the electric motor A, which always drives with the same constant power.
IMPORTANT: If the tightening of the belt drive is not correct it can be because
the bracket B which transmits the correct power from the
electric motor is too tight or stuck. Disassemble the parts,
clean, and grease the rocking mechanism before reassembling
the parts.
