Needle Threader (Adjustment Of Needle Threader) - Brother PE-180D Service Manual

14. NEEDLE THREADER (ADJUSTING THE NEEDLE THREADER)
STANDARD
• When the hook has passed through the hole of the needle (75/11 or 80/12), the hook should be in the middle
of the hole with the same clearances between it and the left and right sides of the hole.
• The clearance between the top of the needle hole and the top of the hook at this time should be 0 – 0.1 mm.
ADJUSTMENT
1. Turn the hand wheel to raise the needle until the needle point is 7 mm or more above the top of the needle
plate. (Use a 75/11 or 80/12 needle for this.)
2. Loosen the two screws of the needle threader base.
3. Operate the needle threader, and move the needle threader base to the right and left so that the hook
passes exactly through the center of the needle hole, and then tighten the two screws.
4. Loosen the screw of the positioning support.
5. Operate the needle threader, and move the needle threader positioning guide up and down so that the
clearance between the top of the needle hole and the top of the hook is 0 - 0.1 mm.
6. Check that part A of the needle threader base is parallel to the needle threader positioning guide, and then
tighten the screw of the positioning support.
* If they are not parallel, the needle threader positioning guide will hit the needle threader base, which could
damage the needle threader.
