Turn the pulley manually to position the needle bar at the lowest point about to move back up. Then, loosen the fixed
screws on the film as in Fig. 8 and align the
“
DOWN
”
film with the film adjustment baseline and the sensor housing
baseline as in Fig. 12 & 13. Tighten the fixed screws just enough so that the film does not rotate. In the same way, place
the thread take-up lever at the highest point, then loosen the fixed screws again and adjust the
“
UP
”
film as in shown the
figure. Be careful that the
“
DOWN
”
film A that was tightened before does not move when adjusting the
“
UP
”
film.

7) Check for Stop Position of Sewing Machine
Check for the machine stop position after moving the needle
up and down by pushing the reverse button. See whether the
carved sign on the arm and the white carved sign on the
pulley are aligned when the needle is in an up position. If not,
adjustment to the photo film of the location detector or to the
location of the magnetic holder will be necessary since there
may be problems with the trimming. In other words, the
needle
’
s up-stop position should be identical with the stop
position of the needle bar after the trimming operation, which
would signify that there is nothing wrong with the operation
timing of the trimmer. (See Fig. 14.) (Refer to the explanation
about the Adjustment of Location Detector on page 14.)
