Raise
Presser Foot and Needle Bar, then turn power on again
1. Turn the machine off and attach the carriage unit.
2. Raise the needle bar to the highest position and push the needle bar to the left.
3. Open the embroidery arm and push the carriage all of the way out towards the back and to the left.
4. Put your ear up the machine and then turn it on. Listen for which step motor ‘stutters’ or does not calibrate. Follow the service book to adjusting/replacing the specific unit.
Warning
1. The needle plate is not attached properly.
2. The needle plate micro switch needs to be adjusted.
Stop for Safety Purposes
1. Replace the foot controller.
2. Check for a tight or stuck clutch by the hand wheel.
3. 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.
4. If you continue to have the problem, loosen the screws that hold the metal, lower shaft supporter. While the machine is running slow-to-medium speed, tighten the screws.
5. 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.
6. Clean the lower shaft sensor and make sure the shield plate going thru this sensor is not hitting the sides of the sensor.
7. If you still get the error, replace the DC motor or lower shaft sensor (in this order)
1. Turn the machine off and attach the carriage unit.
2. Raise the needle bar to the highest position and push the needle bar to the left.

Raise
Presser Foot and Needle Bar then Turn Machine on Again
1. Turn the machine off. Raise the needle bar to the highest position and raise the presser foot.
2. Open the embroidery arm. *Slowly & firmly*, move the carriage all the way towards the back and all the way to the left.
1. Turn the machine off. Raise the needle bar to the highest position and raise the presser foot.
2. Open the embroidery arm. *Slowly & firmly*, move the carriage all the way towards the back and all the way to the left.
3. Push
the needle bar to the left.
4. Open the face plate. Lower the needle threader only half-way down by manually turning the black threaded bar. (See the diagram on the inside of the face plate.)
5. Turn the machine on. The carriage should return to the home position, the needle bar will center itself, the needle threader will return to the up position, and the tension unit will calibrate. If you still get an error, check to see which does not calibrate. Check the connections, any binds, clean the gears, etc. If the error pops up on the screen only after 10 seconds or you hear a highpitched ‘screeching’ or ‘whining’ sound, you have a problem with the feed dog drop step motor. Check the connections, thread caught in the gears, any binds, etc., or replace the unit.
Lock
There’s a problem with the DC motor. Check the connections and make sure the shield plate going thru its sensor and is not loose or touching the sides of the sensor. Make sure both the shield plate
and sensor are not damaged. If either the shield plate or sensor is damaged or you still get the “Lock” error, replace the DC motor.
Raise Presser Foot (when the presser foot is down and you try to run the machine)
There’s a problem with the feed dog drop step motor. Check the connections, thread caught in the gears, any binds, etc., or replace the unit.
Low Bobbin Thread (you need the green & red bobbin gauges [#00310KGAUGE] to fix this):
1. With the machine off, hold down the Start/Stop & Reverse buttons, then turn the machine on.
2. Press ‘Bobbin’.
3. Insert the red bobbin gauge. Press ‘Key’ until you get the most common number, then press ‘MEM1’.
4. Remove the green gauge and Insert the red gauge. Press ‘Key’ until you get the most common number, then press ‘MEM2’.
5. Press ‘X’ to save it and turn the machine off.
Presser Foot (P)
1. Go into embroidery mode and select any built-in design.
2. Attach the ‘P’ foot and lower the presser bar.
3. Locate the "L"-shaped bracket directly underneath the large, metal bracket that the handle pivots on.
4. On older models, you can loosen the Phillips screw next to the c-clip and push the "L"-shaped bracket slightly downwards. Do not push the bracket towards the front of the machine too much,
as it will hit the needle bar supporter and cause a loud ‘clacking’ sound.
5. On newer models, there will not be a Phillips screw, so you will need to loosen the Phillips screw that holds the sensor this "L"-shaped bracket goes into and move it slightly towards the back of
the machine.These are very fine adjustments. You do not have to turn the machine off each time an adjustment is made. Just press the ‘Start/Stop’ button each time an adjustment is made.
4. Open the face plate. Lower the needle threader only half-way down by manually turning the black threaded bar. (See the diagram on the inside of the face plate.)

you do anything to this machine, check if the machine has the new, updated ‘A’
board.
1. Remove the belt cover.
2. Take a peak in from the side of the machine where all of the wires are going into the ‘A’ board.

B. With the machine off, and the presser foot up, push the triangle-shaped, large, black feed step motor gear back & forth several times. You should just feel the friction of the step motor and no binds in the feed system.
C. Check for thread caught in the gears and clean feed step motor sensor.
D. Replace the feed step motor if necessary.

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.
C. Replace the sensor and/or shield plate if damaged.

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 DC Motor or upper shaft sensor (in this order)
