Loosen the screw w and move the stopper (3.57 nut) e to adjust the operating angle of the thread take-up
solenoid r.
* To reduce the thread take-up amount, move the stopper e upward.
* To increase the thread take-up amount, move the stopper e downward.
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.
Loosen the nut w and move the connecting rod lever e to the left or right to adjust so that the V section A is
aligned with the index mark B on the needle plate when the sewing machine in the stopped position and the
movable knife q is pushed to the machine pulley side so that there is no play.
At the time of shipment from the factory, the thread take-up amount (stroke) of the thread take-up lever q is
adjusted as shown in the table below. You may need to adjust this setting depending on the sewing conditions
to prevent the thread from pulling out at the sewing start.
