A3. If you do not get an error, switch the zigzag step motor & feed step motor connections on the ‘A’ board.

A4. Raise the needle bar to its highest position, and then turn the machine back on. If you do not get the error, replace the ‘A’ board. If you still get the error, replace the zigzag step motor.

B1. Turn the machine off. Raise the presser bar & raise the needle bar to its highest position.

B2. Turn the machine on. If you do not get the error, turn the machine off, lower the needle bar to its lowest position, and then turn it back on.

B3. If you do get an error, switch the zigzag step motor & feed step motor connections on the ‘A’ board.

B4. Raise the needle bar to its highest position, and then turn the machine back on. If you do get the error, replace the ‘A’ board. If you do not get the error, replace the feed step motor.

Stop for Safety Purposes

1. Replace the foot controller first.

2. The machine may be jammed. Remove the timing belt to locate whether the bind is on the upper shaft or lower shaft. If it is the upper, there may be thread caught in the take-up lever or crank

pin. If the lower shaft is binding, check hook clearance & hook backlash.

3. Check the connections.

4. Remove the hand wheel, end bushing, belt wheel, and large spring. Clean and oil all parts thoroughly then reassemble.

5. Check the upper shaft sensor. Make sure the shield plate is going perfectly thru the middle of the sensor. Replace the sensor if damaged.

6. Clean the sensor on the DC motor and check if the shield plate on the motor is not loose or hitting the sensor. If either the sensor or shield plate is damaged, replace the motor.

E4: Thread Cutter Motor.

1. Check the connections.

2. Check & clean the gears.

3. Check the position of the microswitch and adjust if necessary.

4. If you still get the error, replace the thread cutter motor.

LO:

1. Replace the foot controller.

2. The machine may be jammed.

A. Remove the timing belt to locate whether the bind is on the upper shaft or lower shaft. If it is the upper shaft, there may be thread caught in the take-up lever or crank pin. If you still have a

bind, loosen the screws that hold the plates that hold the shaft in place then re-tighten.

B. If the lower shaft is binding, check hook backlash.

3. Clean the sensor on the DC motor and check if the shield plate on the motor is not loose or hitting the sensor. If either the sensor or shield plate is damaged, replace the motor.

4. Check the upper shaft sensor. Make sure the shield plate is going perfectly thru the middle of the sensor. Replace the sensor and/or shield plate if damaged.

5. If you still get the error, replace the upper shaft sensor or DC motor (in this order).

E9: Upper Shaft Sensor.

A. Check the connections.

B. Clean the sensor and make sure the shield plate is going perfectly thru the middle of the sensor. Replace the sensor and/or shield plate if damaged.

LO: Replace the foot controller.

1. Check for a tight or stuck clutch by the hand wheel.

2. The machine may be jammed. Remove the timing belt to locate whether the bind is on the upper shaft or lower shaft. If it is the upper shaft, there may be thread caught in the take-up lever or

crank pin. If the lower shaft is binding, check hook clearance, hook backlash. Check the lower shaft rear bushing for any black ‘gunk’. If there is, replace the lower shaft and rear bushing.

3. Clean the sensor on the DC motor and check if the shield plate on the motor is not loose or hitting the sensor. If either the sensor or shield plate is damaged, replace the motor.

4. Check the upper shaft sensor. Make sure the shield plate is going perfectly thru the middle of the sensor. Replace the sensor and/or shield plate if damaged.

5. If you still get the error, replace the upper shaft sensor or DC Motor (in this order).

To Diagnose if the Fuse has Blown

 Perform the following step for the following errors: “E1” and “E2” before doing anything else.

Put the needle in the highest position and then turn the machine on. If you get “E1”, turn the machine off, put the needle in the lowest position, and then turn it back on. If you get “E2”, the

customer jammed the machine and it blew the 3.15A, 250V, white thermo fuse (#000182904) on the back of the 'A' board.

E1: Zigzag Motor.

A. Check the connections.

B. With the machine off, push the needle bar to the left & right several times. You should just feel the friction of the step motor.

C. Check for thread caught in the gears and clean zigzag motor sensor.

D. Replace the zigzag motor if necessary.

E2: Feed Motor.
