The upper thread left on the needle after trimming can be controlled by selecting solenoid-driven thread release mechanism, preventing the thread drift from the needle and the skipping of stitches during the beginning sewing. (KM-857-7)
The large oil tank mounted in the middle of the arm automatically lubricates individual moving parts, dissolving the burden of frequent lubrication.
The thread winding device attached to the front of the arm reduces unnecessary movements of the operator, increasing the productivity.
The direct connection of the presser foot knee-lifting device to the machine facilitates simplicity at the same time guarantees light and soft operations.
