4.1 Oil level and venting
The oil level must be checked prior to commissioning (please see chapter 5.2 "Service and
Maintenance Work").
If the gear unit has already been filled with an initial filling prior to delivery, the vents must be fitted
after installation.
The following table shows the usual oil filling state of oil spaces on delivery:

The position of the vents can be obtained from the specific dimension sheet for the order or from
section 7.1 "Standard positions of the oil drain, vent and oil level". For more detailed information about
the vent option used (e.g. FV, EF, DB), refer to section 5.2.10 "Venting".
The sealing plug which is used for transport must first be removed and the vent installed in the same
position. The sealing plug of gear units that are filled with oil is marked with red paint.
Information
Auxiliary gear units (option WX) and first stage gear units (option WG) can be fitted with a pressure
vent (option DR). The pressure vent must be unlocked prior to commissioning. Refer to the operating
and installation instructions B 1000.
The sealing plug which is used to close the vent hole for transport is marked with red paint.
The connecting flange between the industrial gear unit and the auxiliary gear unit is always equipped
with a pressure venting device. This device, as well as the pressure venting device on the industrial
gear unit (only for ATEX-certified gear units) must be unlocked as shown in Figure 23.
