Make certain that the voltage switch on the motor is set correctly for your use. This machine is set up for 110V usage. Set the 110/220V Switch to 110V (Switch to the left) unless you have your outlet changed to 220V by a qualified electrician. Rewiring of the plug and an approriate outlet is required for 220V usage.

2.The rotation of the motor can also be set to clockwise or counterclockwise rotation. This setting should always be set to the right, which makes the sewing machine pulley rotate counterclockwise. Do not use this setting to reverse the direction of the machine. Use the Reverse Control Lever (22e) to reverse the stitch feed direction when sewing.
