PREPARING FOR BOBBIN WORK
E-90
l
Using scissors carefully trim the thread tail
as close to the bobbin as possible.

Beginning of wound thread
m
Install the bobbin wound with thread.
Whether or not tension should be applied to the
bobbin thread depends on the type of thread being
used.
■
When tension is applied to the
bobbin thread
Insert bobbin into bobbin case so the thread
unwinds from the left side.
Then correctly pass the thread through the tension
spring as shown below.

CAUTION
• Use a bobbin thread that has been correctly
wound. Otherwise, the needle may break or
the thread tension will be incorrect.
• The included bobbin was designed specifically
for this sewing machine. If bobbins from other
models are used, the machine will not operate
correctly. Use only the included bobbin or
bobbins of the same type (part code:
X52800-150).

Note
• Slowly and evenly wind the thread around
the bobbin.
• For best results, wind the bobbin so the
thread is snug and not twisted.
CAUTION
• If thread extends beyond the top of the bobbin
too much, the thread may become tangled or
the needle may break.
Memo
• If inserting thread tail through bobbin hole is
difficult, bobbin can be wound by holding
the tail and wrapping thread around inside
base. Then carefully trim thread tail so it
does not extend from the side of the
bobbin.
CAUTION
• When winding the bobbin, make sure the
thread is not frayed. Embroidering with frayed
thread may result in the thread catching on
the tension spring of the bobbin case, the
thread completely becoming tangled or
damage to the machine.
• Do not guide the bobbin thread completely
through the groove in the needle plate cover,
otherwise the lower threading cannot be done
correctly. Thread only as far as shown below.
