Topping up oil with compressor operating

Topping up oil is permitted during compressor operation.
Be sure that this oil is the same as in the plant (refer to Section 2.4, Page 35).
Without affecting the operation of the compressor, the oil may be topped up by
means of a separate oil pump. This pump enables the oil to be forced into the
crankcase via the oil charging valve, against suction pressure.
