6.6 Filter
6.6.1 Return oil filter
General
The return oil filter cleans the oil before it returns to the tank.
There are two return oil filters connected in parallel. A return oil filter consists of a tube con-
taining two filter inserts. The tubes are mounted inside the hydraulic oil reservoir.
The filter inserts should be replaced according to the maintenance schedule but if the re-
turn filter's pressure gauge on the operator display indicates "Clogged filter" (red zone on
the scale), all return oil filters must be changed immediately.
