(*1)

If the knee switch is used to momentarily lower the presser foot, the presser foot cannot be raised by operating the

 

treadle when the sewing machine has stopped.

 

 

 

In such cases, the presser foot can only be lifted and lowered using the knee switch.

(*2)

Adjustment of the treadle unit is required when changing this function.

 

Change the hooking position of the spring inside the treadle unit, and set the depression stroke. (Refer to “12. TREADLE

 

UNIT”.)

 

 

(*3)

When set to ON, treadle operation is disabled, so it should always be set to OFF.

 

If it is set to ON, [DIP SW4] (green) and [Err 101] (orange) will appear alternately in the main display of the operation

 

panel.
