WARNING :
When the adjustment of the position is performed, make sure of the shape of the sewing pattern. If the
feed plate interferes with the needle hole guide, it will result in the danger of the needle breakage or the
like. Also, if the pedal is depressed during the adjustment, the button clamp unit will go up or come down.
So, be careful.
Do not depress the pedal to the second step, during the adjustment, in a state that the sewing LED lights
up. The button carrier will actuate by so depressing the pedal. So, be careful.

referring to 1) and 2) in "V.2. Position of the button
clamp jaw lever" p.17 .
