The work holder is driven by a stepping motor. You can change a stitching pattern simply by specifying the

pattern No. affected

2.

Wide-range

The X and Y scale can be independently set 0.01 to 4 times the sizeofthe original pattern. This is further

supported by the machine's unique function whereby pattern enlargement/reduction is done by increasing or

decreasing the stitch length or the number of stitches. The combination of these functions permits highly

flexible pattern enlargement and reduaion.

3.

Permits

As for input through the main unit, the feed is operated by meansofa switch in the operation panel. In this way, appropriate data are input so as to meet the requirementsof the sewing material which corresponds to

the sewing needle. Pattemscan also be easily input using the optional input device (PGM-5A).

Descends when the feeding frame switch is pressed. Another press on the switch causes the feeding frame to ascend.

The machine is started by turning the start switch ON with the

feeding frame down.

Used to stop machine operation during a stitching cycle. After a

temporary stop, the feeding frame can be moved along the stitching line by operating the backward or forward switch. The interrupted

stitching cycle can be completed by pressing the start switch.

Alternatively, the return to origin switch may be pressed for quick move to the sewing start point or the 2nd origin.

Counter

Counts the number of garments sewn, and indicates when to replace the bobbin by means of an alarm. When

the quantity of the bobbin thread has been reduced to the preset level, the counter flashes on and off urging

you to replace the bobbin. Sewing is not possible while the counter is flashing on and off. Press the reset

switch after replacing the bobbin, and the counter will be reset to "000", allowing the machine to be restarted.

(The counter switch is turned OFF at the time of delivery.)

5. Set ready switch/READY (Sewing LED) Sets off the following series of operation when pressed after setting the pattern No., X/Y scale, counter and

scale switch (INC/DEC of stitch length or INC/DEC of number of stitches):

1) The specified pattern or patterns are read from the floppy disk.

2) Operation is performed based on the entered scale data. While the compulation is being executed, the

sewing LED (READY) flashes on and off.

Forward/Backward

When the forward switch is pressed with the feeding frame down, the material is fed forward by one stitch.

When the backward switch is pressed with the feeding frame down, the material is fed backward by one stitch. If these switches are kept pressed, the material is fed slowly for the first stitch, after which it is

automatically fed quickly.

7. Return to origin

When this switch is pressed during a temporary stop, the feeding frame will automatically move to the

sewing start point or the 2nd origin, and the feeding frame will go up and stop.

8. Jog keys (Numeric key 2, 4, 6, 8: A mark)

These keys function as numeric keys while the READY lamp is OFF, and work as jog keys while the READY lamp is ON. If any of these keys is pressed with the feeding frame down at the sewing start, the

needle will move in the direction shown by the arrow on the pressed key. At this time, the movementofthe

needle is automatically stored in memory. Set the 2nd origin at the desired position within the material

feeding range.
