Settings 1. MOTOR BELT TENSION If the motor belt tension is too tight or too loose, machine will not run smoothly. Adjustment 1. Remove the front and rear enclosures. 2. Loosen the 2 screws (a, b) 3. Move the motor up or downward and tentatively tighten the screws.
Settings 3. BACKLASH OF HOOK GEAR If there is too much play on the hook gear on the turning direction, it may be the cause for machine 0.1-0.3 mm not to sew properly and/or making excessive sewing noise. Check 1. Free play at the tip of hook may be 0.1-0.3 mm. Note: To do this check on least 3 different spots during the revolution of the hook by turning the handwheel.

Turn the handwheel toward you until the needle is its lowest point. At this time, the mark (a - very small molded line on edge) on the lower shaft timing pulley must be facing toward you.
Settings 5. GAP BETWEEN NEEDLE AND HOOK If the needle hits against the hook, it may be the cause of needle and thread breakages. If the gap between needle and hook is too big, it will cause to skip stitches. Check and adjust as follows: Prior to make this adjustment, check that the needle is not bent and the needle is inserted correctly.
