8.1.2 Filling the hydraulic system
▶
Make sure that the maximum filling pressure does not exceed 2 bar.
The hydraulic power unit can be filled as follows, see fig. 22:
1.
Via the filling and breathing filter (standard).
2.
Via a filling coupling (optional filling device, see chapter 17.3 "Accessories")
installed at the return flow (G1/2).
– Install the filling coupling at the hydraulic power unit as illustrated in fig. 22.
– Replace the air filter in the assembly kit against the filling and breathing filter
and ensure that filling is no longer realized via the air filter.
The filling level must be within the marking on the filling level indicator.
Fig. 22: Filling options
Recommendation: Experience has shown that the cleanliness class required for
the operation of the machine/system is already exceeded with new hydraulic
fluids in the original packing drum.
If you want to ensure the cleanliness class, carry out the filling of the hydraulic
power unit using a special filling unit, if necessary, or use a filter station with a
10 µm fine filter.
