Hydraulic system

The first oil change is required after 50 operating hours, further oil changes must be
performed annually. For each oil change, the intake filter of the pump distributor gears
must be replaced.
Proceed as follows for an oil and filter exchange:
– Clean before oil change wide area around the intake filter.
– Change oil only with gears warm after operation.
– Put an oil-resistant collecting vessel of sufficient size underneath.
– Unscrew the closing cap at the oil drain valve (3).
– Screw on the provided oil drain hose. The valve opens and the old oil drains.
– Remove the screw cap (4) of the intake hose from the filter connection. For this
purpose, you need a fork spanner SW 32.
– Loosen the hexagonal bolt connection (5) on the filter flange. The bolt connection
must only be loosened. In no case totally screw off this bolt connection. For this
purpose, you need a fork spanner SW 36.
– Unscrew the 4 hexagonal recess bolts (6 mm) on the filter flange (6) and pull out
the filter element.
– Exchange the filter element for a new one (ROPA item no. 181052600). For instal-
lation always use a new paper gasket (ROPA item no. 181051700) and a new O-
ring (ROPA item no. 412030200). Before assembly, coat them with some oil.
– Retighten the flange (6) and hose line (5/4).
– Unscrew the oil drain hose again and screw on the screw cap on the oil drain valve
(3) again.
– Open the oil filler screw (1) and fill in fresh oil into the filler neck for so long, until
the oil level is in the upper range of the inspection glass (2).
Prescribed oil variants: Gear oil ATF
ATF oil as per Dexron II D
Filling volume: approx. 12.5 litres
Lubrication pump distributor gears failed!
– Start diesel engine and watch the R-Touch. The warning icon must disappear
from the R-Touch within 10 seconds.
– Let the diesel engine run for a minute, then shut it off.
– Wait at least 10 minutes, then again check the oil level – as described above, in
case of need, correct oil level.
7.3 Hydraulic system
WARNING
Hazard from pressure accumulator!
The pressure reservoirs (1) of the hydraulic system are constantly under high internal
pressure, even if the remaining hydraulic system is already rendered pressureless.
– Work on the pressure reservoirs may only be performed by especially trained peo-
ple who are familiar with handling of pressure reservoirs.
– Render the system pressureless before all work on the hydraulic system or on the
pressure reservoirs.
– Work on the hydraulic system may only be performed by people having been
instructed about the special risks and hazards when working on hydraulic systems.
