14. MAINTENANCE
All maintenance operations must be carried out with machine still, disconnected from any feeders and
disconnected from the suction and delivery piping.
Change the reducer oil after the first 50 hours of functioning by loosening the drain plug in the lower part of the
reducer. Subsequently, the oil must be changed every 1000 hours of functioning or annually. For synthetic type
oil, follow the supplier instructions.
Do not forget to regularly check the oil level through the refuelling plug rod.
Every three months check the diaphragm and the valves for wear.
During the winter period with the machine still, protect the pump from freezing; drain any liquids from inside
the pump body making them leak out of the delivery valve, prior to tilting the same pump or through the pump
body drain plus found underneath the same body.
