3.1 Installation of Motor Module
A: Fix the three bracket screws into the reserved holes on the table of the sewing machine,
then fix the motor under the table by the motor bracket. Adjust the position of the motor
bracket so the motor pulley and the machine pulley are aligned properly.
B: Adjust the tension of the V-belt; press the belt with one kilogram force, concave down 1,5
cm is good, if not, the tension of the V-belt must be adjusted. Mount the V-belt cover and
tighten the connecting bolts between motor and bracket.
3.2 Installation of Control Box
Drill two holes (Ø 3 mm, 1 cm deep, hole pitch 195 mm) in the right front side under the table
and fix the control box firmly with the supplied screws. Insert the 2 x motor plug, the synchro
plug and the plug of the speed control unit into the corresponding sockets. Then bind the
cables together and fix them far away from the V-belt so the V-belt can not damage the cables.
