•
Use a chain pipe wrench to unscrew the filter to be replaced
(part A ).
•
Oil the seal of the new filter which must be tightened and
secured
by hand only.
•
Start up the machine and ensure that there is no leakage
near the seal; if there is; switch off the machine and check the
condition of the machine and that it is correctly positioned in
its slot.
FIG. 5
WARNING: The old filter is impregnated with
polluted and harmful mineral oil. It must therefore be
sent to the special collection centres.

-- 12.4.1) CHECKING OF OIL SEPARATOR ELEMENT --
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 described in 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.
To find out the degree of blockage of the oil separator filter proceed as follows:
- Start up the machine
- Partially open the delivery piping until the control panel gauge indicates the working pressure.
- Read the pressure on the internal gauge 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.
-- 12.4.2) INSTRUCTIONS FOR THE REPLACEMENT OF THE OIL SEPARATOR ELEMENT
--
1. This operation must be undertaken with the machine at a standstill, and with no pressure inside the oil
separator tank.
2. To prevent the risk of soiling the machine as the result of oil leakage which make occur on the
replacement of the oil, we recommend that a few cloths be placed under the compression unit.
3. Unscrew the oil separator filter (part. B fig.5).
4. Re-assemble the filter making sure the lubricate the filter seal element. The filter must be secured by
hand only.
