Venting the filter:
- Fill the open filter case with hydraulic oil to just below the upper rim.
- Should the oil level drop, fill with oil.
The oil level slowly lowering by about 1/4 in./min. (1 cm/min) is normal!
- When the oil level remains steady, mount the assembled unit with the new filter cartridge, carefully
into the housing and tighten the locking screws of the lid (B).
- Open the vent screw (H).
- Mount a transparent hose (l) on the vent screw and lead it into an appropriate container.
- Start the engine and run it at idle speed.
- Shut-off the bleeding screw (H) as soon as the oil discharged through the hose is clean and free of
air bubbles.
The process from mounting the filter lid until starting the engine should take place within 3 minutes or
the oil level will drop too much in the filter case.
Check the seal after changing the filter.
