Every time needle up/down compensation switch
1
is pressed, the needle goes up when it is in its lowest
position or comes down when it is in its highest position.
This compensates the stitch by a half of the predetermined
stitch length.
Note, however, that the machine does not run continuously
at a low speed even if you keep the switch held pressed.
Also, note that the needle up/down compensation switch is
inoperative after turning the handwheel by hand.
Thread trimming is operative only at the time of stitch
compensation after depressing the front part of the pedal once.

• When material edge sensor
1
is pressed, ON/OFF of the material edge
sensor is changed over.
• When the material edge sensor, which is optionally available, is
connected to the operation panel, the ON/OFF switch of the material
edge sensor becomes effective.
• If the material edge sensor is specified, the sewing machine will
automatically stop running or perform thread trimming when the sensor
detects the material edge.
• When automatic thread trimming switch
1
is pressed, ON/OFF of the
automatic thread trimming is changed over.
• This switch is rendered effective, when the material end sensor is turned
ON for the reverse feed stitching pattern, to automatically activate the
thread trimmer upon detection of the material end.
(if the automatic reverse stitching (for end) is specified, the thread
trimmer will actuate after the sewing machine completes the automatic
reverse stitching (for end).)
• When one-shot automatic stitching switch
1
is pressed, ON/OFF of the
one-shot automatic stitching is changed over.
• This switch is used, in the constant-dimension stitching mode, rectangular
stitching mode, or in the process where the material edge sensor is
specied, to make the sewing machine automatically perform sewing at
the specied speed until the end of the process is reached only by driving
the sewing machine once.
If the material edge sensor is used in combination with the opera-
tion panel, carefully read the Instruction Manual for the material
edge sensor beforehand.
