机器出厂首次使用或较长时间没有使用缝纫机时，请一定向针杆滴 2-3 滴机油，
滴在针杆扎头与针杆的连接处，确保针杆机构润滑。
2, factory oiling
When the machine is used for the first time in the factory or when the
sewing machine is not used for a long time, be sure to drop 2-3 drops of oil
to the needle bar and drop it at the junction of the bar head and needle bar
to ensure the needle bar mechanism is lubricated.
