10-6. Adjusting the thread take-up amount

Thread take-up amount (stroke)
2559Q
At the time of shipment from the factory, the thread take-up amount (stroke) of the thread take-up lever (1) is set to the
standard setting of 5 mm. You may need to adjust this setting depending on the sewing conditions to prevent the thread from
pulling out at the sewing start.
[Adjustment method]
Loosen the screw (2) and move the stopper (3.57 nut) (3) to adjust the operating angle of the thread take-up solenoid (4).
* To reduce the thread take-up amount, move the stopper (3) upward.
* To increase the thread take-up amount, move the stopper (3) 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.
