1) Power Voltage and Power Code Connection
(1) Voltage Specification
Match the indication of voltage to specification of power code and connect the cable.
1. Must not use on condition that voltage specification is different.
2. In case of change the using voltage, refer to the article. [Power Voltage Changing Method]
Single-phase connection( 100V, 110V, 120V, 200V, 220V, 240V)
Three-phase connection (200V, 220V, 240V, 380V, 440V)
(2) Power Voltage Changing Method
In Voltage of 110V series, 220V series and 380~440V specification, you can change into the voltage as follows by just
changing the location of power voltage switching connector

2) Cable Connection to Control Box
A. Internal Wiring of Control Box (Common in all types)
See“Block Wiring Diagram”
Upper Figure is wiring diagram based on KM-2070P-7 model and the wiring in case that selected Knee-lifter
switch (including presser foot solenoid) for option
As KM-2070P model are none-thread trimming type, it does not need to connect cable for thread trimming ,
wiper, tension release solenoid.
Switch cable consists of two; white and blue connector(Knee-lifter switch is option)
White connector : Connect reverse button
Blue connector : Connect Knee-lifter switch (connect presser foot solenoid cable as well)
In case of power cable connection, pay attention to fix to table that interference does not occur with belt.

2) Pattern Setting Method
■Operation Panel Indication Status
■Operation Order
1. Turn on the power.
2. Pressing the key of the desired pattern, the lamp of selected
pattern is on.
·Example: selection of pattern number 3 (3 point zigzag
pattern)
·See 3) for selection of left, right scallop pattern
·See 4) for left and right blind pattern
3. Then, start sewing by stepping on the pedal.
4. Execute thread trimming by stepping back the pedal after
completion of sewing.
(Thread trimming and wiper are options)

Set the desiring pattern
(example: pattern no. 3)
Indication lamp is on.
[Note]
When the power turned on, if buzzer tone rings and U P is displayed on indication device, it means needle bar is not
on the up stop location. Therefore, turn the pulley to the front by hand that the needle bar can be at up stop location. Then,
indication device discappers U P and shows zigzag-width and you can start sewing.
