Intermittent maintenance
Intermittent maintenance has to be carried out:
• at the start of the mowing season;
• before prolonged storage of the machine;
• when the machine is used extensively during the season.
- Grease all points of the machine listed in § 7.2 ‘Lubrication’.
- Grease the spring-loaded locking pins of the yoke lock of the PTO
shaft.
- Check if the PTO shaft telescopes smoothly.
A damaged PTO shaft may cause excessive wear and tear to the
machine and tractor.
- Check correct pretension of 160 mm of the spring of the
breakback device (fig. 21).
The SPLENDIMO 320 MC mower has, in lieu of the spring, a
rubber block which needs to be compressed up to a length of
95 mm.
- Check the V-belts for correct tension.
Dismount the V-belt housing. The tension should be such that
each V-belt can be pushed in, between the pulleys, approximately
10 mm by applying a force of 70 N (7 kg) (fig. 21).
It is recommended to depressurize the V-belts if the machine will
remain out of operation for a longer period of time.
- Check the condition of wear plates, mower discs and knives.
(Replacement of knives: see § 7.4.).
- Check the knife bolts for tightness (fig. 22).
Type

Type
“S”

locking agent.
The torque is 50-60 Nm (5-6 kgm).
- Check the mower discs for tightness (fig. 21). Torque: 150 - 250

allowed to protrude above the pressure piece.
