3.Press the "up" button (L) or the "down" button (K) until the desired number of home position cycles is displayed.

The setting range is between 0 and 9.

*If the number of home position cycles is set to "5", returning to the home position will occur once for every five cycles.

However, when carrying out cycle sewing, the machine will return to the home position once for each cycle program regardless of the number of home position cycles which have been set (unless the setting is "0").

Normal home position cycling will not be carried out if the setting is "0".

4.Press the ENTER button (N) to accept the home position cycle setting. This setting will apply to all program numbers from 1 to 9.

*The display will stop flashing and will start illuminating steadily.

Note: If for some reason an excessive load is applied to the feed bracket which causes it to slip, then there is the danger that this will have an adverse effect on subsequent sewing operations. Therefore, it is recommended that you return to the home position for each cycle (i.e. that you leave DIP switch No. 8 on the circuit board set to OFF).

7-13. Returning to the home position

This is useful for correction purposes when mistiming occurs in the home position cycle because re-sewing was carried out.

*This function is only valid when DIP switch No. 8 on the circuit board is set to ON.

1.When at the home position in AUTO mode, press the RESET button (1) to start sewing from the home position.
