7 MAINTENANCE
Correct machine servicing is necessary with a view to
reliable and safe working
.
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 “7.3 Intermittent maintenance”).
- 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 at the
grease nipples on the cross assemblies, protection tubes
and free wheel clutch (fig. 13).
- Profiled tubes of the PTO shaft to be greased every 8
working hours.
- Grease the slide bearings in which the gearbox pivots every
20 working hours (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 every 40
working hours.
- Apply a few drops of oil to the cams of the breakback
device every 40 working hours (fig. 15).
