Venting the filter:
- Fill the open filter case with hydraulic oil to about 2 cm below the upper rim.
- Should the oil level drop, top up with oil.

The slow sinking of the oil level by about 1 cm/min is normal!
- When the oil level remains steady, mount the assembled unit with the new filter car-
tridge, 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 con-
tainer.
- Start the traction engine at idling speed.
- Shut-off the bleeding screw (H) as soon as the oil discharged through the hose is
clean and free of bubbles of air.
A
The process from the mounting of the filter lid until starting the engine shall take place
within 3 min or else the oil level drops too much in the filter case.

Check the seal after changing the filter.
