bar to close to its highest position.

<KE-436B, 436C>
During an emergency stop, the thread is trimmed and the needle bar stops in the
raised position.
*Note:
When the motor operates in reverse to raise the needle, the thread take-up will stop at a position which is
lower than its normal stopping position. As a result, the thread take-up will rise slightly at the sewing start,
and this may result in the thread pulling out under certain conditions.
