WARNING

Use only regular household electricity for the power source. Using other power sources may result in fire, electric shock, or damage to the machine.

Make sure that the plugs on the power cord are firmly inserted into the electrical outlet and the power supply jack on the machine.

Do not insert the plug on the power cord into an electrical outlet that is in poor condition.

Turn off the main power and remove the plug in the following circumstances:

When you are away from the machine

After using the machine

When the power fails during use

When the machine does not operate correctly due to a bad connection or a disconnection

During electrical storms

CAUTION

Use only the power cord included with this machine.

Do not use extension cords or multi-plug adapters with many other appliances plugged in to them. Fire or electric shock may result.

Do not touch the plug with wet hands. Electric shock may result.

When unplugging the machine, always turn off the main power first. Always grasp the plug to remove it from the outlet. Pulling on the cord may damage the cord, or lead to fire or electric shock.

Do not allow the power cord to be cut, damaged, modified, forcefully bent, pulled, twisted, or bundled. Do not place heavy objects on the cord. Do not subject the cord to heat. These things may damage the cord and cause fire or electric shock. If the cord or plug is damaged, take the machine to your authorized dealer for repairs before continuing use.

Unplug the power cord if the machine is not to be used for a long period of time. Otherwise a fire may result.

0Cut the thread, slide the bobbin winder shaft to the left and remove the bobbin.

Note

When the sewing machine is started or the handwheel is turned after winding the thread around the bobbin, the machine will make a clicking sound; this is not a malfunction.

The needle bar does not move when you slide the bobbin winder shaft to the right.

4Put the bobbin in so the thread comes out in the direction shown by the arrow.

CAUTION

Make sure you set the bobbin so the thread unrolls in the right direction. If the thread unrolls in the wrong direction, it may cause the thread tension to be incorrect or break the needle.

5Hold the end of the thread, push the bobbin down with your finger, and then pass the thread through the slit, as shown.

If the thread is not correctly inserted through the tension-adjusting spring of the bobbin case, it may cause incorrect thread tension.
