7 B-10 B Harness and connector 2.3 Maintenance of ring and brush Maintenance-free from grease job of the contacts. Never apply grease to contacts between rings and brushes, rings for the upper power circuits (6 circuits) and disk type rings for the lower weak signal circuits (24 circuits). These slip-rings adopt carbon brushes on the power and weak signal circuits. These slip-rings have enough operating durability with self-lubricating carbon materials. Therefore grease job is not necessary like metal contacts W E
