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.
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.
Secure the table so that it will not move when tilting back the machine head. If the table moves, it may crush your
feet or cause other injuries.
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.
The following cleaning operations should be carried out each day in order to maintain the performance of this machine and to
ensure a long service life. Furthermore, if the sewing machine has not been used for a long period of time, carry out the
