INNER ROTARY HOOK TENSION

STANDARD

While slowly pulling polyester thread #60 using a tension gauge, inner rotary hook tension should be 0.1-0.12N
(10-12g). The difference between this and the tension for silk thread (#80) should be 0.02-0.03N (2-3g).

ADJUSTMENT

1.

Pass polyester thread #60 through the inner rotary hook correctly, and pull it using the tension gauge.

2.

Adjust the tension by turning the screw to either the right or left using a screwdriver.
NOTE :After adjusting the tension, lock the screw with paint.
