7. Start-up
Observe the instructions in section 3. "Safety instructions"!
• Before and during the start-up, fill out the existing checklists (e. g. "Checklist for oil filling and oil change"
and "Documentation sheet for oil change" in the separately enclosed operating instructions BA 7300)
and file these with the documentation.
NOTICE
Property damage
Damage to the gear unit is possible.
The gear unit must not be taken into operation if the required manual is not on hand.
During start-up the initial run of the gear unit is load free, that is, without grinding material and roller
pressure.
Note
Any setting of the drive in motion represents a start-up.
7.1 Procedure before start-up
The start-up must be carried out with great care by authorised, trained and qualified personnel. Siemens
is not liable/does not extend a warranty for damages caused by incorrect implementation.
For this reason the operating instructions must be adhered to, particularly if maintenance work is carried
out on the mill during which this is rotated and the gear unit along with it.
Before the initial start-up of the drive unit, the exterior and interior preservation might have to be removed
if necessary (see items 4.4.1 to 4.4.4), the lubricant filled in, and various control measures carried out.
7.1.1 Removal of preservative agent from exterior
NOTICE
Property damage
Metallic bright surfaces without protection are susceptible to corrosion.
For avoidance of corrosion, the exterior preservation may be removed only directly before the
assembly.
• The corrosion prevention must be removed from the shaft ends in the area of the couplings that are to
be mounted with suitable means (special solvent).
The corrosion prevention must also be removed from the bright surfaces of the gear unit, onto which
components are to be mounted.
CAUTION
Risk of injury from chemical substances
The solvent must not come into contact with the skin (e.g. the operator’s hands).
The safety notes on the data sheets for the solvent used must be observed.
Immediately remove any spilled oil immediately using an oil binding agent.
Observe manufacturer’s instructions for handling lubricants and solvents.
Wear suitable protective clothing.
