NOTICE
Property damage
With larger filled-in quantities of the "Corrosion Inhibitor N 213
"
(above 5 % of the operating oil
quantity), the mixture of operating oil and "Corrosion Inhibitor N 213" must not be used as operating
oil. Before start-up, the remaining "Corrosion Inhibitor N 213" has to be drained and the gear unit must
be flushed thoroughly with operating oil (in this regard, see item 10.4.)
NOTICE
Property damage
Damage to the gear unit is possible.
The gear unit may not be turned.
Note
Before start-up of the gear unit, the measures according to section 7.1 and 7.2 have to be carried out.
4.4.3.2 Renewal of the gear unit interior preservation through complete filling with preservative or operating oil
A further possibility for renewal of the gear unit interior preservation is to fill the gear unit with preservative
or operating oil until the oil level indicator on the tilting pad thrust bearing chamber shows it is filled
completely with oil.
The durability of this kind of preservation depends on the used oil and has to be enquired from the oil
manufacturer.
For the complete filling, a sealing cap (can be obtained from Siemens) must be mounted on the gear unit
for sealing the input shaft.
The preservation will remain intact for as long as the gear unit remains sealed and the storage durability
of the oil is not exceeded.
Note
Refer to the BA 7300 operating instructions supplied separately for the approved preservative oils. The
viscosity of the operating oil is stated on the rating plate.
For better filling it is recommended to choose an oil with low viscosity, which however is not suitable
for later operation of the gear unit and will thus have to be fully drained. When filling, the filled-in oil
should have a maximum viscosity of 7500 cSt (at VG 320 > 0 °C).
For complete filling, also the later operating oil can be used, which has to be drained to the operating
oil level before start-up.
NOTICE
Property damage
Insufficient lubrication due to the incompatibility of the oils.
If the gear unit is preserved with "TRIBOL 1390" (see "Technical data"), it must be flushed before the
complete filling (see BA 7300).
This flushing oil must not be used for operation.
NOTICE
Property damage
Corrosion damages on the gear unit are possible from the loss of the preservative effect
Filled gear units can become untight and the gear unit oil might leak. Tightness of the filled gear units
must be monitored. Leaks must be removed. Siemens does not accept any liability for damages that
are caused from leaking gear unit oil during storage.
