*To reduce the thread take-up amount, move the stopper e upward.

NOTE:

Do not increase the stroke of the thread take-up lever any more than is necessary.

If the sub-thread tension is too high, the needle thread length may become too short and the thread may come out of the needle. Furthermore, if the sub-thread tension is too weak, the needle thread length may become too long and the underside of the article being sewn may become untidy.
