Lubricants
Unless a special arrangement is made, SEW-EURODRIVE supplies the drives with a
lubricant fill adapted for the specific gear unit and mounting position. The mounting po-
sition (M1 – M6, see chapter "Mounting positions") must be specified with the order. You
must adapt the lubricant fill in case of any subsequent changes made to the mounting
position, see chapter "Lubricant fill quantities"
