10. CLEANING
Turn off the power switch before carrying out cleaning.
The machine may operate if the treadle is depressed by mistake, which could result in injury.
Do not directly touch sharp objects such as the tip of the rotary hook when cleaning the rotary hook, otherwise
injury may result.
When removing the needle plate, auxiliary needle plate and knife unit, use a screwdriver that matches the size of
the screw heads.
If a screwdriver with a size that does not match is used, it may damage the screw heads and cause personal injury
or damage to the sewing articles.
Be sure to wear protective goggles and gloves when handling the lubricating oil and grease, so that they do not get
into your eyes or onto your skin, otherwise inflammation can result.
Furthermore, do not drink the oil or eat the grease under any circumstances, as they can cause vomiting and
diarrhea.
Keep the oil out of the reach of children.
Use both hands to hold the machine head when tilting it back or returning it to its original position. If only one hand
is used, the weight of the machine head may cause your hand to slip, and your hand may get caught.
