Lightly finger-tighten the screw on the right side of the
needle plate. Then, use the disc-shaped screwdriver to
firmly tighten the screw on the left side. Finally, firmly
tighten the screw on the right side.

Insert the bobbin case by following step k in
“Cleaning the race” on page 55.
q
Attach the needle plate cover according to step l in
“Cleaning the race” on page 55.
r
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 “Checking the needle” on page 20 and
“Replacing the needle” on page 20.
■ Checking machine operations
If the needle plate has been removed, check machine
operations to confirm that installation has been completed
correctly.
a
Turn on the machine.
b
Select stitch .
c
Slowly turn the handwheel toward you
(counterclockwise), and look from all sides to check
that the needle falls at the center of the opening in the
needle plate.
If the needle contacts the needle plate, remove the
needle plate, and then install it again, starting with step
m in “Removing the fabric from the machine” on
page 59.
d
Select stitch . At this time, increase the stitch length
and width to their maximum settings.
• For details on changing the settings, refer to “Setting
the stitch width” on page 27 and “Setting the stitch
length” on page 27.
e
Slowly turn the handwheel toward you
(counterclockwise) and check that the needle bar and
feed dogs operate correctly.
If the needle or feed dogs contact the needle plate, the
machine may be malfunctioning; therefore, contact
your nearest Brother authorized service center.
f
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 “Installing the bobbin” on page 14 and
“Replacing the presser foot” on page 21.
g
Correctly thread the machine.
• For details on threading the machine, refer to “Upper
Threading” on page 15.
h
Perform trial sewing with cotton fabric.
Memo
• Since the needle may have been damaged when the
fabric was caught in the machine, we recommend
replacing it with a new one.
Note
• Do not yet install the presser foot and thread.

from the trial sewing, check the upper threading or the
type of fabric being used.
