-- 10.11.1) CHECKING OF OIL SEPARATOR ELEMENT --
This operation is reserved for specialized and qualified personnel.
The frequency is usually estimated as being of about every 2000 working
hours, but it strictly depends on the observance of all the maintenance regulations
indicated in this manual.
Insufficient oil in the tank, failure to comply with the lubricant replacement
frequency indications or use of the machine with clogged cooling radiator, may all result in
serious damage
to the separator filter.
Therefore after having checked the condition of the recovery nozzle (operation
described in paragraph 10.5) and having made sure of the correct oil level in thank, should
there be any further traces of oil in the compressed air, it is necessary to replace the oil
separator filter (fig. 21).
To find out the degree of blockage of the oil separator filter proceed as follows:
- install a gauge at the top of the oil separator and check that the one on the machine is
efficient.
- Start up the machine
- Partially open the delivery piping until the control panel gauge indicates the working
pressure.
- Read the pressure on the gauge positioned at the top of the oil separator and compare
the two values: should a difference of over 1 bar be found, it is a clear indication that the
filter is blocked and it must be neither cleaned or washed, but replaced.
-- 10.11.2) INSTRUCTIONS FOR THE REPLACEMENT OF THE OIL SEPARATOR
ELEMENT
--
1. The operation must be undertaken with machine off and no pressure in the oil
separator tank.
2. Disconnect all the pipes from the connections positioned on the closure flange of the
separator tank, marking them so there is no problem on re-assembly.
3. Loosen the screws (fig. 21, part A) and remove the flange (B).
4. Extract the filtering element (D) together with the seals (C) and (E).
5. Assemble the new seal (E) in the relative slot which has been previously cleaned.
Endure that a metallic insert has been clipped to the seal in order to avoid the isolation
of the filter and the accumulation of static electricity. Otherwise there is a risk of the
separator filter catching fire.
6. Insert the new separator element correctly positioning it into the relative slot.
7. Assemble the second seal (C) with the same precautions as above.
8. Reassemble the flange (B) in the pre-assembly position.
