Winding Adjustment - HIGHLEAD GC0318-1A Series Instruction Manual Parts Catalog

9. WINDING ADJUSTMENT ( Fig.7 )
1) The wound bobbin thread should be neat and tight, if not, adjust the winding tension by turning Tension
Stud Nut ( A ) of bobbin winder tension bracket.
Note: nylon or polyester thread should be wound with little tension, otherwise, Bobbin ( D ) might break or
deform.
2) When the wound thread layer does not present a cylindrical shape as shown in Fig.7 ( a ), loosen Set
Screw ( B ) of bobbin winder tension bracket and slide Bracket ( C ) leftward or rightward. If thread is wound as
shown in Fig.7 ( b ), move the bracket rightward, but if thread is wound as shown in Fig.7 ( c ), move the bracket
leftward.
After adequately positioning the bracket, tighten Set Screw ( B ).
3) Do not overfill the bobbin. The optimum length of thread will fill about 80% of bobbin capacity. This can be
adjusted by Adjusting Screw ( E ) of bobbin winder stop latch.
