Intermittent maintenance
Intermittent maintenance has to be carried out:
• at the start of the haymaking season
• before prolonged storage of the machine
• when the machine is used extensively during the
season.
- Grease the PTO shaft.
- Grease the profiled tubes of the PTO shaft .
- 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.
- Grease the slide bearings in which the gearbox pivots
(fig. 14). Fold the cutter bar up a few times allowing the
grease to spread evenly among the bearings. After that,
grease once more.
- Grease or lubricate all remaining pivot points.
- Apply a few drops of oil to the cams of the breakback
device (fig. 15).
- Check correct pretension of 160 mm of the spring of the
breakback device (fig. 15). The SPLENDIMO 320L disc
mower has, in lieu of the spring, a rubber block which
needs to be compressed up to a length of 95 mm.
- Check the tension of the V-belts.
V-belt tension should be such that each belt can be pushed
in (on the spot shown in fig. 16) approx. 10 mm with a
force of 70 N (7 kg).
- Check the machine for damage and flaws.
- Check the condition of wear plates, mower discs and
knives (for knife replacement - see “7.4 Replacement of
knives”).
- Check the knife bolts (fig. 17) for tightness.
Torque 50-60 Nm (5-6 kgm).
- Check the mower discs for tightness (fig. 17). Tighten the
castellated nut with a torque of 150-250 Nm (15-25 kgm)
and secure it with a split pin. The split pin locking the
castellated nut is not allowed to protrude above the
pressure piece.
We recommend that you first tighten the nut to the minimal
torque and then keep turning until the split pin can be
fitted.
