The 2 x gears in the head of the ibrid nano are made from strengthened nylon, they transfer the power through 90 degrees to the polishing head.
It can happen that if you catch an edge at high speed the gear teeth can break causing a noise from within the head, or a loss of power/drive to the head. The only remedy is to replace the gear set.
Also available, Full Replacement Gearbox - for easier and faster repair.
