1. Do not allow to be used as a toy. Close attention is necessary when this appliance is used by
or near children.
2. Use this appliance only for its intended use as described in this manual. Use only
attachments recommended by the manufacturer as contained in this manual.
3. When lightning begins to strike, turn off(“0”) the power switch and unplug the power supply.
4. Never operate this appliance if it has a damaged cord or plug, if it is not working properly,
if it has been dropped or damaged, or dropped into water. Return the appliance to the
nearest authorized dealer or service center for examination, repair, electrical or mechanical
adjustment.
5. Never operate the appliance with any air openings blocked. Keep ventilation openings of the
sewing machine free from the accumulation of lint, dust, and loose cloth.
