7.7 Pneumatic system
The pneumatic system is to a great extent maintenance-free. Maintenance work is
only required on the compressed air tank. The compressor is maintenance-free. The
compressed air tank is located on the bunker front wall.
Drain the condensation water at the compressed air tank after each
100 operating hours. If the machine is to be taken out of operation for a longer period
(more than a week) the condensation water must also be drained from the com-
pressed air tank. For this, press the drain valve slightly sideward or backward.
CAUTION
Falling and injury hazard!
– Before draining water, stop the machine and switch off the engine.
– The machine must be secured against inadvertent starting of the engine.
– All maintenance and repair work may only be performed by trained personnel.
– Use a stable ladder for all maintenance work on the compressed air reservoir.
– Always wear gloves, protective goggles and suitable protective clothing.
