9) Lubricating device of needle thread and needle cooling device

[ Warning ]
Be sure to turn the power switch off before work.
High-speed sewing generates heat as a result of frictions between the needle and sewing materials. Heat may result in thread
breaks, skipped stitches, or enlarged stitch holes when used with polyester threads or fabrics.
To prevent such troubles, this sewing machine comes attached with the needle cooling device and needle thread lubricating
device as a standard option.
※ Open cover ① of the silicon oiling tank and cover ② of the needle thread oiling tank to check the level of silicon oil. Oil
if necessary.
※ If there is no need for silicon due to specific sewing conditions, remove the felt to prevent the needle and the thread from
passing the dry felt.
