Thank you for your purchase of this sewing machine.
This machine will provide you with excellent performance in two thread overedging, two thread chain stitch
ing (14U13) and interlocking (safe.ty stitching)(14U13) from light to heavy material (lawn to denim). Please

voltage of the motor.
• Disconnect the power-line plug from the socket outlet when changing needles, presser feeet or
throat plates, or when leaving the machine unattended. This eliminates the possibility of start
ing the machinery by accidentally pressing the speed controller.
*
• Do not pull the fabric while you are stitching as this may deflect the needle, causing it to break.
• Before cleaning your machine, disconnect the power-line plug from the socket outlet.
• Do not attempt to adjust the motor belt. Contact your nearest Service Center should any
adjustment be required.
• Handle the foot controller with care and avoid dropping it on the floor. Be sure not to place
anything on top of it.
• When sewing closely watch the area being sewn to avoid injuries from needles and knives.
• Use only the handle to lift and move the machine.
