1. Notice YSC-8331 is used in system of industry sewing machine. For perfect operation and safety, installation and operation must be supervised by professional. 1.1 Work environment ▲ Please use 220V AC in ±10% ranges. ▲ To avoid the false operate, please keep the product away from the high electromagnetic interference.
4. Function of Operation Box P107 operation box diagram Operation Function Double start tacking, A is the stitches of forth sewing; B is the stitches of back sewing. They are both in range 1~15. Start Tacking Selection Single start tacking, A is the stitches of forth sewing;...

▲ Once the pedal is stepped forward, F, G stitches will be completed with E times. ▲ Constant-Stitch Sewing will perform the Program Sewing number of segments and times as setting, when the stitches are zero, machine will stop immediately. ▲...
5. Operation of the Normal Function 5.1 Free sewing mode If either is enable, then the mode is free sewing. to enable or disable the start tacking. to enable or disable the end tacking. Turning wheel button clockwise or anticlockwise to move the cursor, push wheel button to twinkle the parameter want to modify, then turning wheel button clockwise or anticlockwise to change parameter, push wheel button to save the change, or push...
5.2 Bar tacking mode is enable, then the mode is bar tacking. Turning wheel button clockwise or anticlockwise to move the cursor, push wheel button to twinkle the parameter want to modify, then turning wheel button clockwise or anticlockwise to change parameter, push wheel button to save the change, or push to cancel change.
5.3 Program mode is enable, then the mode is program mode. Change “Seg” parameter to select the segment which wants to setup. Each segment can use to enable or disable the start tacking. Each segment can use to enable or disable the end tacking.
5.4 Parameter setup Press can enter the parameter menu, press it again will back to sewing mode interface. See the picture above, the current cursor is under “S”, which indicates the parameter type, push wheel button to twinkle the “S”, then can change the type you want, total 9 types can be selected: speed parameter timing parameter...
5.5 Parameter recover When in parameter menu, if cursor move to the first word, push wheel button can enter parameter recover function. Two choices can be made, recover to “Last value” or “Default value”. After select, push wheel button will display “Are you sure?”, push wheel button again to confirm, push will back to last step.
