7.3.2) Oil Supply
1) Oil Volume Check
• Look at the oil window② on the bed cover.
When the oil is at the "HIGH" mark③, it
means oil is sufficient.
• If oil is below the "LOW" line ④, supply
more lubricant following the order below.
2) Oil Supply
• Use the authentic SunStar lubricant.
(Lubricant can be found in the accessory box).
• Loosen the oil supply entrance screw ①.
• Supply lubricant until the oil reaches the
"HIGH" line ③ on the oil window of the bed
cover. Make sure that lubricant does not
overflow.
1) Make sure that lubricant does not move above the "HIGH" line ③. If not, lubricant might leak.
When oil supply is completed, tightly fasten the oil tank entrance screw ①.
2) When the sewing machine sits on the table safely, please pay attention to make the oil tank⑤ is
perpendicular. If it leans to one side, oil might leak out.
Caution
3) Please make sure that the reflux filter⑥ is on the groove of the oil pan.
Otherwise, oil cannot be properly inhaled.
