7 MAINTENANCE
• Correct machine servicing is necessary with a view to
reliable and safe working.
• Maintanance should always be carried out whilst the
PTO shaft between the tractor and the machine is
disconnected.
7.1
Maintenance after operations
• Clean the machine thoroughly. After jet-cleaning allow for
a few moments rotation of the discs so that the water is
swept away.
• Check the mower knives and discs for tightness and
damage (see par. 7.3).
• Check the safety cover for damage.
• Grease the machine with a rust preventive.
• Grease the piston rod with an anti-corrosion agent if a
longer period of inactivity is anticipated. Remove the agent
when putting the machine back into operation. If not,
sealing of the ram may be affected after hardening of the
anti-corrosion agent.
7.2
Lubrication
• PTO shaft to be greased every 8 working hours by the
grease nipples on the cross assemblies, protection tubes
and free wheel clutch (fig. 15).
• Profiled tubes of the PTO shaft to be greased every 8
working hours.
• Grease the PTO shaft above the drive element every 100
working hours in way of the grease nipples on the cross
assemblies. For this purpose, the cover A (fig. 16) and the
sealing plate B have to be dismounted. Remove soil and/or
crop material, if any, from the hat.
• Grease the pivots of the intermediate frame every 40
working hours.
• Grease the bearing blocks of the conditioner rotor every 8
working hours (fig. 17).
• Grease or lubricate all remaining pivot points every 40
working hours.
• Apply a few drops of oil to the cams of the breakback
device every 40 working hours (fig. 18).
