7.1.2
Filling with lubricant
•
Undo and remove fastening screws on the inspection and/or assembly cover.
•
Remove cover with seal from housing (seal will be used again).
Using a filter (approx. mesh 60 μm), fill the gear unit with fresh oil up to the MAX mark
on the oil dipstick or the middle of the oilsight glass. Remember to fill the oil pockets
above the bearings, in the case of bevelgear units at the input shaft on the inside.
The quality of the oil used must meet the requirements of the separately supplied BA 7300 EN
lubricant recommendation manual, otherwise the guarantee given by Siemens will lapse. We
urgently recommend using one of the oils listed in BA 7300 EN, 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 dipstick or oilsight glass are decisive for the amount of oil to be filled in.
In the case of gear units fitted with forced lubrication or an oilcooling system, the oil circuit must
also be charged with oil. To do this, briefly start up the gear unit with addon pump (observing
the description in section 8).
•
Check the oil level in the gearunit housing.
The oil must come up to the middle of the oil sight glass.
The oil level must be at the upper mark on the oil dipstick.
Remove any oil spillage immediately with an oilbinding agent.
•
Place inspection or assembly cover including seal on the housing.
•
Place the fastening bolts of the cover and tighten them to the specified torque (see item 6.20).
7.2
Startup
Before startup, replace the yellow plastic screw plug with the air filter (see also notice
on gear unit).
After the first startup of the external oilsupply system the oil level should be checked (gear
units with oilsupply system only).
•
Check the oil level in the gear unit.
When the oil has cooled down, the oil level should be between the marks of the oil dipstick.
When the oil is warm it may slightly exceed this mark. It must in no case be allowed to fall below
the mark. If necessary, top up to the correct level.
