When the multiple spindle head is installed on a machine,
disconnect the machine from the power supply and se-
cure it against reactivation before any work on the multiple
spindle head.
Check the oil level before startup.
To do so, hold the multiple spindle head in the vertical
position so that it rests on the spindles, and check that the
oil level is at the centre of the inspection glass.
