A detailed view of the gear unit can be obtained from the drawings in the gear­unit documentation.
Before start­up, replace the yellow plastic screw plug with the wet­air filter (see also
notice on gear unit).
Before screwing in, 2 out of the 8 sealed holes on the underside of the wet­air filter
must be opened.
7.1.2 Filling with lubricant
• Unscrew the oil dipstick or screw plug for filling with oil.
Fill the gear unit with fresh oil, using a filter (maximum mesh 25 μm).
The quality of the oil used must meet the requirements of the separately supplied BA 7300
instructions manual, otherwise the guarantee given by Siemens will lapse. We urgently
recommend using one of the oils listed in table "T 7300" (for a link, see the BA 7300 document
supplied separately), because they have been tested and meet the requirements.
Information on the type, quantity and viscosity of the oil is given on the rating plate on the gear
unit.
The oil quantity shown on the rating plate is to be understood as an approximate quantity. The
marks on the oil dipstick or the middle of the oil­sight glass are decisive for the amount of oil
to be filled in. Should both be available, use of the oil dipstick has priority.
