General inspection of the gear unit
The general inspection of the gear unit should be carried out by Siemens Customer Service, as our
engineers have the experience and training necessary to identify any components requiring replacement.

Lubricants
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 to the Internet, see back cover), as they have been tested and meet
the requirements.
Note
To avoid misunderstandings, we should like to point out that this recommendation is not intended as
a guarantee for the quality of the lubricant delivered by your supplier. Every lubricant manufacturer
must provide its own guarantee for the quality of its product.
Information on the type, viscosity and required quantity of the oil is given on the rating plate on the gear unit
and/or in the documentation included in the delivery.
The total operating oil quantity for the gear unit, the oil-supply system, and the pipework can be found in
the set-up plan.
If the oil-supply system and the pipework are not included in the scope of delivery by Siemens, the
operating oil quantity for the gear unit is shown on the rating plate (see section 1. "Technical data").
The quantity value specified in the setup plan and on the rating plate is understood as an approximate
quantity. The marks on the oil level indicator of the main gear unit, the tilting-pad thrust bearing and/or the
oil-supply system (for models with tank) are decisive for the oil quantity to be filled in.
The BA 7300 instructions manual relating to the gear unit lubrication and Table "T 7300" containing the
current lubricant recommendations of Siemens can also be consulted on the internet (see back cover).
The oils listed there are subject to continuous testing. Under certain circumstances, the oils recommended
there may be removed from the range at a later time or be replaced by further developed oils.
We recommend checking before any oil change whether the chosen lubricant is still approved by Siemens.
