Information
Incorrect oil level indication due to trapped air for Option WX with installation position M5/M6
During commissioning and after changing the oil, air (air pockets) may become trapped in the gear
unit oil bath. These disappear during operation. The resulting space fills with lubricant. Because of
this the oil level may deviate in comparison with the initial filling. This process may take several days.
During this period an incorrect display of the oil level cannot be ruled out.
• Check the oil level at regular intervals, especially after commissioning or changing the oil.
4.2 Activating the vent
• The vent must be fitted after installation if the gear unit comes with an initial filling.
Remove the screw plug which is used for the transport. This screw plug is marked red. Install the
vents in the same position.
The position of the vents can be obtained from the specific dimension sheet for the order or from
Section 7.2 "Standard positions of the oil drain, vent and oil level". Detailed information about the
venting option which is used (e.g.: FV, EF, DB) can be found in Section 5.2.12 "Cleaning or replacing
the vent".
Information
Auxiliary gear unit (Option: WX) and first stage gear units (Option: WG) can be equipped with
pressure venting (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.
