Most of the "sealed cartridge type" BBs are not meant to have the bearing preload adjustable or to be taken apart and serviced. That is the glory of them, plug/play/forget/replace when worn out...
If the play is not noticed when riding I might not do anything. If the play is enough to cause problems with front chain meshing, shifting or excessive chain rub on cage then i would replace the BB with one that wasn't loose.
Have you taken this up with the outfit that you bought the BB from? Andy
