General maintenance instructions
This machine requires care and maintenance like any other technical
device. The extent and the frequency of the maintenance work depends
essentially of the operating and deployment conditions, which are very
different in many cases. In case of more difficult operating conditions,
the machine must have maintenance in shorter intervals as scheduled
for normal operation.
The maintenance intervals are determined according to the running time
of the operation hours counter; for this, additional maintenance work has
to be performed during the running-in time according to the running-in
regulations. The works necessary for care and the conservation of the
operational safety of the machine are listed in the following sections.
The running-in regulations, the servicing intervals and the care
measures for the diesel engine can be found in the operating manual of
the engine manufacturer and must be observed.

Operation monitoring
Air filter
The operability of the air filter cartridge and the safety cartridge is
monitored by an electric contamination indicator. Only if the pilot light
[203] flashes, must the air filter cartridge or the safety filter cartridge be
replaced.
810-16
Pressure filter hydraulics
The pressure filters for the hydraulic system are monitored by an
electrical contamination display. Only if the pilot light [214] flashes, must
the filter insert of the hydraulic filters be replaced prematurely.
A prematurely contaminated filter can be a first hint for a damage
in the hydraulic system.

Preliminary fuel filter
According to the water content in the fuel, more or less water
precipitates in the drain housing of the fuel pre-filter. If the pilot light [227]
flashes, the water sump must be drained.
