9) Needle Cooling Device and Oil Supply Device for Needle Thread
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.
The silicon-type oil is the most efficient.
Note :
Open [the silicon oil supply tank cap①] of the needle
cooling device and [the needle thread oil supply tank cover
②] of [the needle thread oil supply device] to check the oil
volume. When oil is insufficient, supply more oil.
※ 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.
[ Warning ]
Be sure to turn the power switch off before work.
