Preparatory measures for gear unit installation

NOTICE
Property damage
Damage to the gear unit from corrosion is possible.
The packaging must not be opened or damaged beforehand if the packaging is part of the preservation.
The products supplied are listed in the dispatch papers. Check for completeness immediately on receipt.
Parts damaged and/or missing parts must be immediately reported in writing to Siemens.
• Before installation of the gear unit in the vertical mill, remove the packaging material and transport
equipment, and dispose of it according to regulations.
• Perform a visual check for damages and soiling.
Note
Adhesive tapes on the labyrinths and the round cord hollow profile between the gear unit housing and
the output flange may only be removed directly before the start-up.
WARNING
Serious personal injury can be caused by a defective product
If there is any visible damage, the gear unit must not be taken into operation.
The instructions in section 4. "Transport and storage", must be observed.
NOTICE
Property damage
Corrosion is possible when the gear unit is opened for too long.
Any opening of the gear unit (e.g. by removing the adhesive tape on the input shaft or on the output
flange, removing the round cord hollow profile, or by opening a lid) reduces the guaranteed
preservation period. If the gear unit is opened, it must be taken into operation within one week. If the
start-up is delayed, special measures are necessary to maintain preservation (see item 6.3.1).
NOTICE
Property damage
Damage to the sliding bearings is possible.
The input shaft of the gear unit may be rotated maximally 1 time for positioning during installation, only
when the tilting pad thrust bearing chamber is filled with oil up to the specified level.
• Remove the corrosion protection from all of the preserved surfaces using a suitable cleaning agent.
NOTICE
Property damage
Damage from inadequate stability of the gear unit is possible.
The gear unit must be set up on a level, secure, vibration-free and rigid foundation. The levelness of
the gear unit standing surface is especially important, as the contact pattern of the teeth and the
carrying portion of the axial tilting pad thrust bearings depend on it and the service life of the gear unit
is affected by it.
Clean the gear unit and foundation set-up surface.
