Use & Maintainance of Plain Machine

  PLAIN MACHINE

Changing Over The Specified Voltage And Changing The Fuse Be sure to turn off the power to the machine before starting the procedure Insert a slotted screwdriver into the slot of change over the voltage and set the voltage to a desired voltage. Set the operating voltage to the position with ‘Ñ’ mark.

Replacing the fuse

Be sure to turn off the power to the machine before starting the procedure

Starting the procedure and remove the cap from the fuse holder. Then, take out the fuse and replace it with a new one.

Error Message

The error will be shown by the number of times of flashing on an off of the LED lamp in the control box when any error is detected during operation.

No of times of LED Flashing	Error Description	Item of confirm
1	Defective ED-2	Check whether connector of the ED-2 is securely inserted Check whether adjustment of material detection is properly performed
2	Abnormal memory	Turn OFF and return ON the power switch
3	Abnormal synchronizer	Check whether connector of the synchronizer is securely inserted.
4	Abnormal panel communication	Check whether the panel cord connector is disconnected or loose
5	Motor lock	Check whether thread is caught in the motor pulley shaft Check whether anything is entered in the motor pulley cover Check whether the v-belt is not on the motor pulley

Safely Circuitry

The machine incorporates the following safety circuitry

                        If the V-belt is not on the motor pulley

                        If the sewing machine is driven with its V-belt off, the safety circuitry is actuated in about 2 seconds to stop the whole operation. If this happens, turn the power OFF, properly mount the V-belt before turning the power ON again. This safely circuitry is also actuated when the sewing machine has been subjected to any abnormal load.

If a needle position detector has failed

            Failure of the upper or lower needle stop position detecting function is automatically directed by the safety circuitry. Then, the machine actuates as one with a clutch motor, and it is possible for the motor to be used in this state until it is repaired
