7.3 Intermediate maintenance
Intermediate maintenance has to be carried out:
• at the start of the season;
• before prolonged storage of the machine;
• when the machine is used extensively during the season.
- Grease all points of the machine listed in chapter 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 the tyre pressure (fig. 14).
- Check the machine for damage and flaws.
- Check all bolts and nuts for tightness.
When tightening loose bolts/nuts the torques listed below
should be applied.
- Check the rotors for sagging (fig. 16).
• Place the machine on a level surface.
• Place two wheels - pair by pair - on a 60 mm elevation to
ensure sagging of the adjacent segment.
• Ensure horizontal machine position.
• The stop bolts (fig. 15) should only just foul the abut-
ment surfaces.
Turning of the abutment bolt (for adjusted sagging) may
lead to damage to the hydraulic retraction rams and/or
protection brackets.
