With these compressors, the frequency of the oil changes is closely related to how dirty the circulating
oil is. Pay close attention that no foreign substances which can damage the oil (dust, steam, gases)
make it through the air intake filter into the compressor unit's oil circuit. Very humid intake air and
condensation inside the machine have an influence on the life span of lubricating oil so that the oil
change times must also be reduced in this case. The change time intervals given are based on intake
air which is normally available and if foreign substances (dust, steam, gases) are not present in large
amounts.
When changing the oil, the old oil must be drained as fully as possible, because the used oil strongly
decreases the life span of the new oil.
Different lubricating oils must not be mixed. When changing this type of oil, the oil must be completely
drained from the oil circuit.
