Insert the bobbin case by following step k in
“Cleaning the race” on page 83.
q
Attach the needle plate cover according to step l in
“Cleaning the race” on page 83.
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 28 and
“Replacing the needle” on page 28.
■ 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.
The needle will automatically move left and right.
b
Select Straight stitch (Middle).
* Refer to “Stitch Chart” on page 41.
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 or feed dogs contact the needle plate, the
machine may be malfunctioning; therefore, contact
your nearest Brother authorized service center.
d
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 22 and
“Replacing the presser foot” on page 29.
e
Correctly thread the machine.
• For details on threading the machine, refer to “Upper
Threading” on page 23.
f
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
• If an error occurs, the machine may be
malfunctioning; so contact your authorized Brother
dealer or the nearest Brother authorized service
center.
Note
• Do not yet install the presser foot and thread.
