MAINTENANCE
1) Stop the system and verify there is no pressure in the lter.
2) Unscrew the threaded pin (1) to close the bulkhead (2) on the
bottom of lter housing and to prevent oil leakage from the
system.
3) Collect the oil inside the lter with a suitable container.
4) FSC31-FSC41-FSC51 Loosen the nuts/screws (3) on the
cover (4). N.B. it is not necessary to disassemble the nuts, use
the slots on the cover. FSC61-71-81: Unscrew the screws (3).
5) FSC31-FSC41-FSC51 Turn the cover (4) clockwise and remove
it. FSC61-71-81: remove the cover (4).
6) Remove the dirty lter element (2).
N.B. The used lter elements and oil dirty lter parts are
classied “Dangerous waste material” and must be disposed of
according to the local laws, by authorised Companies.
7) Check the lter element part number on the lter label or in the
ordering and option chart.
Use only original spare parts.
8) Insert the clean element (5) in the housing (6) resting on the
bottom gasket (7).
Lubricate the new element o-ring gasket (3) with oil.
9) Check the correct positioning and condition of the gasket (8)
and o-ring (9) respectively assembled on the cover (4) and
housing (6). Lubricate with oil if necessary. If damaged, check
the catalogue or call the customer care service.
Insert the clean element into its seat with care.
10) Position the cover (4) and tighten the screws/nuts (3) until it
stops.
11) Screw the threaded pin (1) up to the stop on the cover (4). This
opens the bulkhead (2) on the bottom and allows the oil inlet
from the tank. N.B. The o-Ring (10) ensures the seal between
the pin and the cover.
Accessories:
Safety switch. The threaded pin (1) must be completely screwed to
close the contact of microswitch (11). If the pin is unscrewed, the
microswitch opens. If damaged, check the catalogue or call the
customer care service.
Clogging indicator. If damaged, unscrew and replace it (check the part
number in the ordering and option chart). Apply a thread-sealing and
screw until tight.
N.B. an over-tightening can damage the thread.
