Siemens recommends a complete oil change after a storage time longer than 24 months:
• For gearboxes with long-term preservation.
• For gearboxes supplied completely filled with oil.
Follow Checking and changing lubricants (Page 514).

Mounting the oil expansion tank

An oil expansion unit can be used depending on the power, input speed, mounting position and
transmission ratio. The oil expansion unit is used to equalize changes in the oil volume caused
by temperature fluctuations in operation.
Before commissioning the gearbox, replace the screw plug with the oil expansion unit.
Oil expansion unit size 39 - 89
The unit is supplied as a mounting kit, and can be attached to the geared motor vertically or
at an angle.
