Precaus for the use of household electric sewing machines

As an electrical appliance, the household electric sewing machine must comply with the following basic safety operation instructions in the process of use. 
 1. Household sewing machines are not prepared for use by people (including children) who are physically weak, slow to reflect or have mental disorders, except under the guidance or help of those who are responsible for safety. Children should be supervised to ensure that they do not play with utensils. 
 2. When the sewing machine is left unattended, disconnect and rotate all switches to the "OFF" position, and then unplug the power plug. 
 3. If the machine breaks down or falls into the water, if the power cord or plug is damaged, or does not work fully, please do not operate the machine.

 5. Don't let anything fall into or insert into the vent of the machine.
