9. Pattern selection
Direct selection of patterns through a transparent touch panel and indication of selected pattern on LCD.
10. Number of patterns
Practical patterns 53, Continuous patterns 34, Adherence one point 34, One point 168, Lettering characters 4 fonts 450, large pattern 31, practical one point 51
11. Constant-position needle bar stopper
The machine stops with its needle up or down using the synchronizer shield plate and detector (photo-interrupter) mounted on the main shaft.
When the thread trimming presser is raised, when the embridering device is used or when the bobbin is to be wound, the machine stops with its needle up. In a case
other than those described above, the machine stops with its needle down.
12. Prevention of wrong-setting of needle
It is designed so as not to insert the needle in the wrong direction.
13. Operation guide
How to operate the sewing machine, advice and how to sew are indicated on LCD.
14. Prevention of overheat of motor
If the sewing machine motor shaft is locked, the power supplied to the motor is automatically turned OFF after 1 to 1.5 seconds.
If the motor becomes extraordinarily hot in such cases as the sewing machine cotinuously runs at high speed, the thermal sensor built in the motor detects and stops
the machine operation. (The power is turned ON again after the motor has cooled down.)
15. Automatic bobbin winder
When performing the embroidering, exclusive bobbin thread can be wound to bobbin without removing bobbin. In addition, after bobbin winding, threading to bobbin
thread tension spring and thread cutting are performed. Then sewing can continue.
