Diagnostic Test 06 / PH (Phase or Lower Shaft Shield
Positioning Sensor)
1.
Turn the hand wheel toward you. Lower the
needle bar from its highest to lowest position. A
buzzer sounds and the LCD displays the stitch
length symbol when the machine is at feed
phase.
(Feed phase begins as the needle goes
down into the fabric and ends as needle
comes back up out of the fabric – this is when
the machine does not feed the fabric.)
2.
Raise the needle bar from its lowest to its
highest position. The buzzer sounds and the
LCD displays the stitch width symbol. The LCD
displays the stitch width symbol when the
needle bar is at zigzag phase.
(Zigzag phase
is from when the needle is well out of the fabric
and finishes well before the needle goes back
into the fabric). This is when the machine does
do zigzag.)
3.
Adjust the lower shaft shield plate position if
necessary. See Diagnostic Appendix, 06 for
more information.
