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 compen-
sates 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 in-
operative after turning the handwheel by hand.
Thread trimming is operative only at the time of stitch compensa-
tion after depressing the front part of the pedal once.
