1) Adjusting the Lower Dead Stop of the Needle
Lower dead stop of the needle refers to the
lowest point of the needle movement. It is
important for timing of the needle and the
rotary hook and must be adjusted precisely.
Usually you don

t have to adjust it, but if the
lower dead stop is not correct, follow the
procedures below.
①
Turn the hand lever and set the angle of the
upper shaft signal board at 178
°
.
②
Install the lower dead stop gauge (included
in the SWF accessory kit).
③
Unscrew the needle bar holder and move
the needle bar up and down. Fix the holder
so that the needle bar softly touches the
upper part of the gauge.
