Maximum sewing speed is increased to 7,000sti/min.The needle bar mechanism and upper looper mechanism have been redesigned to require no lubrication. The frequency of stain removal or re-sewing is reduced.The most-advanced dry technologies, such as the special surface treatment applied to the major drive unit and the grease feeding method, contribute to higher durability.The machine does not splash oil after a long-period of use.
