Before you start

Check that the following conditions have been met:

  • For gear units with extended storage option, observe the information in chapter Gear unit with long-term preservation.
  • Remove any present transport protection.
  • Secure the existing oil drain valves against unintended opening.
  • As of size X..220 and for X2F..180 – 210, avoid no-load operation independent of the driven machine because operation with a load below the minimum load can damage the rolling bearings of the gear unit.
