7.3 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 PTO shaft above the drive element in way of the
grease nipples on the cross assemblies. For this purpose,
the cover A (fig. 13) has to be removed. Remove soil and/or
crop material, if any, from the hat.
- Grease the pivots of the intermediate frame (fig. 15).
- Grease or lubricate all remaining pivot points.
- Apply a few drops of oil to the cams of the breakback
device (fig. 14).
- Check correct prestress of 160 mm of the spring of the
breakback device (fig. 14) fitted to the SPLENDIMO 240 /
280 T disc mowers. The disc mower SPLENDIMO 320/
360 T has, in stead of the spring, a rubber bloc which needs
to be compressed up to a length of 95 mm.
- Check the machine for damage and flaws.
- Check the condition of wear plates, mower discs and knives
(for knife replacement - see § 7.4).
- Check the knife bolts for tightness.
Type “S” (fig. 15): lock bolts with Loctite 243 or use new
bolts and locking agent. Torque: 50-60 Nm (5-6 kgm).
Type “N” (fig. 18): torque 50-60 Nm (5-6 kgm).
- Check the mower discs for tightness (fig. 15/16). Torque:
150-250 Nm (15-25 kgm). 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.
