8 Insert the bobbin case and then attach
the needle plate.
* Refer to steps 9 through 11 of “Cleaning the
Race” on page 255.
9 Check the condition of the needle, and
then install it.
If the needle is in a poor condition, for example, if it is
bent, be sure to install a new needle.
* Refer to “Changing the Needle” on page 36.
Checking Machine Operations
If the needle plate has been removed, check
machine operations to confirm that installation has
been completed correctly.
1 Turn on the machine.
The needle moves to the left and right.
2 Select Straight stitch (Middle).
* Refer to the “Stitch Chart” on page 273.
3 Slowly turn the handwheel toward you
(counterclockwise), and look from all
sides to check that the needle falls at the
center of the hole in the needle plate.

If the needle or feed dogs contact the needle plate, the
machine may be malfunctioning; therefore, contact
your authorized Brother dealer or the nearest Brother
authorized service center.
4 Turn off the machine, and then install the
bobbin and presser foot.
Never use a scratched or damaged presser foot.
Otherwise, the needle may break, or sewing
performance may suffer.
* Refer to “Setting the Bobbin” on page 40 and
“Changing the Presser Foot” on page 48.
5 Correctly thread the machine.
* For details on the machine, refer to “Upper
Threading” on page 42.
6 Perform trial sewing with normal fabric.
If the bobbin winding starts when the thread is
not passed through the pretension disk correctly,
the thread may become tangled beneath the
bobbin winder seat.
Wind off the thread according to the following
procedure.

1 Touch [Stop] once to stop the bobbin
winding.
• If an error occurs, the machine may be
malfunctioning; therefore, contact your
authorized Brother dealer or the nearest
Brother authorized service center.
• Do not yet install the presser foot and thread.
• The thread may have become tangled as a
result of incorrect upper threading. Make sure
that the machine is correctly threaded.
• Remember when sewing thin fabrics, select a
center stitch that is shorter in length and use
the straight stitch needle plate for straight
sewing stitches. A lightweight paper stabilizer
can also be placed on the underside of the
fabric.
If the Thread Becomes Tangled
Under the Bobbin Winder Seat
CAUTION
• Do not remove the bobbin winder seat even if the thread
becomes tangled under the bobbin winder seat. The
cutter in the bobbin winder seat may cause injury.
