4. PREPARATION BEFORE SEWING￿

Use the digital tension to adjust the tension as appropriate for the material being sewn. (Refer to “Setting the tension value”.)

Furthermore, turn the tension nut (1) (sub-tension) to adjust the remaining length of upper thread to 35 - 40 mm, when the thread take-up lever is not used.
