7.1.3 Filling with lubricant
Note
When preserving with operating oil or when represerving with operating oil (see section 4.4), lubricant
is not poured in, but the operating oil is drained off until a specified oil level has been reached.
• Remove any dirt in the area of the inspection and/or assembly cover or that of the marked oilfilling
point.
• Undo and remove the fastening screws of the inspection and/or assembly cover.
• Remove the cover with the seal from the housing. The seal will be used again.
• Unscrew the air filter with the reducing screw or the wetair filter.
• Using a filling filter (mesh approx. 25 μm), fill the gear unit with fresh oil until the oil rises until the lower
edge of the oilsight glass or in the oillevel indicator, or until the oil comes up to the lower mark on the
dipstick. Do not put in any further oil. The viscosity of the oil in cold condition will cause the oil level to
continue rising slowly. If necessary, but only after the oil level has steadied, pour in further oil up to the
middle of the oilsight glass, to the middle between the MIN and MAX marks on the oillevel indicator
or to the middle between the MIN and MAX marks on the dipstick. During the filling operation, make sure
that no dirt can enter into the gear unit.
Note
The quality of the oil used must meet the requirements of the separately supplied BA 7300 operating
instructions, 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 the back cover), as 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 actual oil
quantity to be put in is the middle of the oilsight glass, the MIN and MAX marks on the oillevel indicator
or the MIN and MAX marks on the dipstick.
DANGER
Risk of explosion
Ignition of a potentially explosive atmosphere possible through overheating of the gear unit in case of too
low oil level.
Check the oil level.
Under no circumstances must it be allowed to fall below the lower edge on the oilsight glass, the MIN
mark on the oillevel indicator or the MIN mark on the dipstick. If necessary, top up oil to the correct level.
Note
In case of gear units fitted with forcefeed lubrication or an oilcooling system, the oil circuit must also be
charged with oil. To do so, briefly start up the gear unit with addon pump. Observe the instructions in
section 8, "Operation".
