10-6) Correct Position Of Needle; 10-7) Adjusting Half-Turn Film For Color Change - SunStar SWF/B Series User Manual

10-6) CORRECT POSITION OF NEEDLE

① Make sure to check the position of the needle - it may change during machine delivery or leveling. First check if
the needle is bent. Then turn the main shaft lever to set the shaft at around 130° . Position the needle at the lower
dead stop and check if the needle is at the center of the needle hole on the plate.
[CAUTION]
Check the needle position on all heads.
② If the needle is not in the correct position, unscrew the brackets (2 screws) to adjust the head and the needle (see
[Fig.10-12]).

10-7) ADJUSTING HALF-TURN FILM FOR COLOR CHANGE

The machine will stop automatically if either of the needle position lamp or the needle set lamp blinks on the color
change box. In this case, adjust the half-turn film as below.
• Adjust the position of the color cam using the SWF spanner (in basic accessory kit). Open the half-turn film cover and
align the center of the half-turn sensor with the center of the film. The roller should be at the center of the straight line of
the color change cam when the needle stops at the center of the needle hole on the plate as shown in [Fig.10-13].
