nating vertical movement of the walking foot and
the presser foot will be maximized. (Lamp above

To change over the amount of the alternating
vertical movement of the walking foot and the
presser foot by means of the knee switch, join
the knee switch and the mounting plate, sup-
plied with the unit, together and x them on the
table with wood screw.
