机器出厂时,机油均被排放,因初次使用缝纫机前,请一定要加入机油,推荐
使用机油:加油时请拿开标有 OIL 的加油口盖子,把机油加到油尺的上下刻线之
间,加油完成后转动缝纫机,看油窗是否有机油喷出,如果没有机油喷出,请进行
检修。(When the machine is delivered from the factory, the oil is discharged.
Be sure to add the oil before using the sewing machine for the first time. It
is recommended to use the oil. When filling, open the filler cap marked with
OIL and add the oil between the upper and lower engraved lines. Turn the
sewing machine after finish to see if there is any oil spilled in the oil window.
If there is no oil spilled, please carry out overhaul.)
