• Check the rotary hook of a machine head whose MENDING lamp

(green) is blinking to see if the thread is caught.

2.Check that the machine pulley is set to 100˚ of the scale, and

press the END switch.

[Measures]

1.If the thread end is left too long or stitching is left loosened

before starting embroidering, the thread is caught in the

spring or hold it with a hand.

3.Leave thread of about 60 ~ 70 mm from the needle hole when

starting embroidering.
