I would do a thorough clean and oiling of the machine, just to make sure, the 130 is a stable low noise machine. I assume it's electrical, but it's much the same for a treadle; go through all joints and resting points, the machine has to rest stabely in the cabinet, and the cabinet feet should ideally be fitted with sturdy furniture felt. Are any of them missing? There's usually felt where the machine bed rest in the cabinet too. All feet has to rest evenly on the floor, no tilt in either direction. Check the motor belt, not too tight, slightly on the loose side, and it should run smoothly; it is all about condition of the motor belt (you might need a new), and straight line between motor pulley and hand wheel. Hardwood floors or tiles are no poblem with the right precautions. Check the cabinet for anything needing tightening up, every thing should be firm, nothing should wiggle.
