(2) Adjusting the film of the position sensor
① Assemble the films and position sensor in the order as shown
in the figure.
② Upon the completion of the assembling, position the needle shaft tight at the rising point from the lowest needle position by manually
rotating the pulley. Loosen the film-fixing screw, and adjust the DOWN film so that the film-adjsting line and the sensor housing
calibration line are matched. Tighten the film-fixing screw just to the extent that the film can not be rotated. Likewise, position the thread
take-up at the highest position. Loosen the film-fixing screw, and adjust the UP film as shown in the figure, while using caution not to
move the DOWN film which is already adjusted earlier. Tighten the adjusted film with the fixing screw.
(3) Adjustion the films of reverse rotation sewing machines
※For reverse-rotation sewing machines, the film-adjusting lines located at right edge of the “UP”and “DOWN”film should be matched to
the center line of the sensor.
