General notes
The power hydraulics (VarioPower
ted in a separate frame in the platform sub-
frame. This has enormous pay load advan-
tages, e.g. for snow-clearing and protecting
the hydraulic components from corrosion. If
the power hydraulics are not needed, they
can be removed, including the frame, from
the platform subframe. Further information
can be obtained from a Mercedes-Benz Ser-
vice Centre.
The following components of the power
hydraulics are located in the platform sub-
frame:
Hydraulic oil reservoir
R
Oil cooler
R
Hydraulic pumps
R
Oil filter
R
The hydraulic pumps are selectively driven via
a propeller shaft from an engine-driven power
take-off.
The power hydraulics consists of two open oil
circuits. It operates continuous consumers or
attached equipment that consume low quan-
tities of oil.
