TURNING THE MACHINE ON/OFF
TURNING THE MACHINE ON/OFF
WARNING
• Use only regular household electricity as the power source. Using other power sources may result in fire, electric
shock, or damage to the machine.
• Turn the main power to OFF 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
• 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 the main power to OFF 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, or cause fire or
electric shock. If the cord or plug is damaged, take the machine to your authorized retailer 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.
• When leaving the machine unattended, either the main switch of the machine should be turned to OFF or the plug
must be removed from the socket-outlet.
• When servicing the machine or when removing covers, either the machine or the electrical set must be unplugged.
• For U.S.A. only
This appliance has a polarized plug (one blade wider than the other). To reduce the risk of electrical shock, this plug is
intended to fit in a polarized outlet only one way.
If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install
the proper outlet. Do not modify the plug in any way.
Insert the power cord into the power cord

■ Display Precautions
• Only touch the display with your finger or the touch pen included with the machine. Do not use a
mechanical pencil, screwdriver or any other hard or sharp objects. In addition, do not press the display with
extreme pressure, otherwise damage to the display may result.
• All or part of the display may sometimes become darker or lighter due to fluctuations in the surrounding
temperature or other changes in the environment. This is not a sign of a malfunction. If the display is difficult
to read, adjust its brightness (see page 21).
• The display may be dark immediately after the machine is turned on. This is a normal characteristic of the
backlight and is not a sign of a malfunction. After approximately 10 minutes, the display should reach its
normal level of brightness.
• If you are not directly facing the display, the colors may be distorted or the screen may be difficult to read.
This is a normal characteristic of the display and is not a malfunction. Be sure to sit in front of the display
while using it.
When the machine is turned on, the opening screen appears. The machine can be set so that the opening screen is
not displayed (see page 21).
Lightly press the display with your finger. Depending on the setting either, "1-01 Straight stitch (Left)" or "1-03
Straight stitch (Middle)" is automatically selected (see page 20).

supplemental spool pin to wind the bobbin while
sewing using the main spool pin.
CAUTION
• The included bobbin was designed specifically for

Setting the Bobbin
This section describes how to set a bobbin wound with
thread into the machine. You can begin sewing without
pulling up the bobbin thread. If you wish to pull up the
bobbin thread, for example, when sewing gathers,
follow the procedure described in the next section.
CAUTION
• Use a bobbin thread that has been correctly wound.
Otherwise, the needle may break or the thread
tension will be incorrect.
CAUTION
• Be sure to hold down the bobbin with your finger
and unwind the bobbin thread correctly. Otherwise,
the thread may break or the thread tension will be
incorrect.
Lightly hold down the bobbin with your right
e
hand, and then, while slightly pulling the
thread with your left hand, guide it through
the groove.

After guiding the thread completely through
f

Pulling Up the Bobbin Thread
There may be some sewing applications where you
may want to pull up the bobbin thread, for example,
when making gathers or with free-motion quilting.
Follow the procedure described below to pull up the
bobbin thread.
Memo
Thread the upper thread bef or e pulling up the bobbin
thread. For details, see “Upper Threading” on page 29.
Follow steps a through d from the previous
a
section to insert the bobbin into the bobbin
case.
Guide the bobbin thread through the groove,
b
following the arrow in the illustration.
Note
• Do not cut the thread with the cutter.
• Do not attach the bobbin cover.
→ A loop of the bobbin thread comes out from the hole
in the needle plate.
Pull out about 100 mm (approx. 3-4 inches) of

Upper Threading
This section describes how to thread the machine and

indicate the threading order.
CAUTION
• Be sure to thread the machine properly. Improper
threading can cause the thread to tangle and break
the needle, leading to injury.
• When using accessories not included with this
machine, attach the accessory to the machine after
threading the machine.
