13.4-11 CHECKING THE OIL MIST SEPARATOR FILTER
The oil mist separator filter is expected to last for around 2000 hours of work but is closely related to a
careful observance of all maintenance requirements given in this manual. An excessively low oil level, not
following recommended oil change intervals, and using the machine with the cooling radiator clogged may
cause serious and irreparable deterioration of the filters.
Therefore, if after checking and cleaning the oil recovery nozzle (operation described in Section 13.4-7) and
making sure of the proper oil level in the tank, there are still traces of oil in the compressed air, the oil mist
separator filter will need to be replaced.
To determine the degree of restriction of the oil mist separator filter, proceed as follows:
1) Install a pressure gauge upstream of the separator and make sure that the engine is ready to be
started
2) Start the engine
3) Partially open the air valve until the pressure gauge on the control panel shows the maximum
operating pressure
4) Read the value of the pressure gauge located upstream of the oil mist separator filter and compare
the two gauge readings. If there is a difference of more than 1 bar/14.5psi, replace the separator
filter. The oil separator filter must never be washed with water.

13.4-12 REPLACEMENT OF THE OIL MIST SEPARATOR FILTER
To replace the oil mist separator filter, proceed as follows:
1) Stop the engine and release all pressure in the oil separator tank.
2) We recommend using a cloth in order to catch any oil spillage that may
occur during the replacement of the oil mist separator filter.
3) Remove the oil mist separator filter; the filter is situated above the oil
separator tank
4) Replace with the new filter, making sure to lubricate the gasket.
5) The filter must be tightened by hand only.
