Basics
Sewing machines typically operate on standard alternating current (AC) mains voltage, which is typically 110-120V in North America and 220-240V in many other parts of the world. The power consumed by a sewing machine depends on the type of machine and the functions used. Conventional sewing machines typically consume between 60 and 100 watts.
Wiring
* Use an electrical cord rated for the required power of the sewing machine.
* Make sure the wires are not damaged or frayed.
* Connect the sewing machine to a grounded outlet.
Grounding
Grounding electrical devices is necessary to protect against electric shock in the event of a short circuit or malfunction of the device. Sewing machines must be properly grounded using a three-wire electrical cord with a grounding pin. The ground pin is usually a round prong on the plug.
Electronic foot switch
Many modern sewing machines are equipped with an electronic foot switch that controls the sewing speed. The foot switch is connected to the sewing machine using a special cable.
LED lighting
Many sewing machines also come with LED lights to illuminate the work area. LED lighting consumes little energy and provides bright light.
Repair and maintenance
* Never attempt to repair a sewing machine yourself unless you are qualified to do so.
* Clean the electrical contacts of your sewing machine regularly using alcohol and a cotton swab.
* Do not use the sewing machine in wet conditions.
Safety
* Always unplug the sewing machine from the outlet when not in use.
* Do not leave the sewing machine running unattended.
* Keep the electrical cord away from heat sources and sharp objects.
