Increasing/decreasing the stitch length method.
The max. sewing speed can be set limited to any
value within a range of 200 to 2,500 rpm using the
up/down key. (100 rpm steps)
Machine head 46 kg, Control box 16.5 kg
X (lateral) direction 100 mm Y (longitudinal) direction 60 mm

New Defrix Oil No. 2 (equivalent to ISO VG 32) (supplied by oiler)
EEP-ROM (32k byte)
Allows a pattern to be enlarged or reduced on the X axis and Y axis independently when sewing a pattern.
Used to stop machine operation during a stitching cycle
Used to detect needle thread breakage to automatically stop machine.
1 to 99 patterns can be selected by specifying the desired pattern Nos. (In case of EEP-ROM)
Tells the time to replace the bobbin by the bobbin thread counter. (Max. 9,999 pcs.)
In case of a power interruption, the pattern being used will automatically be stored in memory.

After the completion of sewing, the needle can be stopped in its upper position by rotating the needle bar
in the reverse direction.
LK-1930
0.1 to 12.7 mm (adjustable in 0.1 mm step)
3.5 inch micro floppy disk (2DD, 2HD)
Memory pattern : 44 to 691 patterns
1% to 400% (1% step)
Increasing/decreasing stitch length or the number of
stitches can be selected.
The max. sewing speed can be set limited to any
value within a range of 200 to 2,500 rpm using the
external variable resistor.
1 to 999 patterns can be selected by specifying the
desired pattern Nos.
(In case of floppy disk)
Using the jog switch, a 2nd origin (needle position after a
sewing cycle) can be set in the desired position within the
sewing area. The set 2nd origin is also stored in memory.
When the needle does not stop in its upper position,
the needle can be brought up to the upper position by
turning again the needle threading switch.
