8.1.2 Start of the hydraulic supply
1. During initial starting and the period immediately after it, any hydraulic
installation must be regularly and carefully checked at frequent intervals.
2. The working pressure and charge pressure must be checked to ensure that they
correspond to the contracted values. Check that the charge pressure conforms
to the charge pressure curve, see chapter, Recommended charge pressure in
data sheet
RE
15300.
3. The pressure in the drain line measured at the motor must be less than 3 bar
(43.5 psi). This pressure limit is important for the life of the motor seals.
4. If leakage occurs, correct the fault and carry out new measurements.
5. Check all lines, connections, screws, etc. and correct if necessary.
6. Check other possible leakage points and replace faulty parts.
7. During the start up period, dirt particles in the system are removed by the
filters. The filter cartridges have to be changed after the first 100 working hours
and after that according to the maintenance chart, Table 19.See also Chapter
10.3: Maintenance plan (second point) about filter clogged indicators.
It is important that the pressure is limited to 250 bar (3626 psi) when starting up
the motor. This is valid for the first 100 hours.
