• Check the knife bolts for tightness (fig. 25).
Type “S”
: lock bolts with Loctite 243 or use new bolts and
locking agent. Torque: 50-60 Nm (5-6 kgm).
Type “N”
: torque 50-60 Nm (5-6 kgm).
• Check the mower discs for tightness (fig. 25). Torque:
150-250 Nm (15-25 kgm). The split pin locking the
castellated nut is not allowed to protrude above the

Dismount the V belt housing. The tension should be such
that each V belt can be pushed in, between the pulleys,
appox. 10 mm (fig. 26) by applying a force of 70 N (7 kg).
It is recommended to depressurize the V belts if the
machine will remain out of operation for a longer period of
time.
• Check the tyre pressure, which should be 310-420 kPa
(3,1-4,2 bar).
