What to do if my Brother S-710A's stitch number display is flashing?
If the stitch number display on the operation panel is flashing, it indicates a problem with the control box. Replace the control box.
What to do if the Brother Sewing Machine starts operating before the presser foot is lowered?
If the sewing machine starts operating before the presser foot is lowered (solenoid-type presser lifter specifications), set DIP switch 2 inside the control box to ON.
Why is there a large degree of puckering on my Brother S-710A?
Excessive puckering may occur if the upper or lower thread tension is too strong; make them as weak as possible. The thread tension spring tensions may also be too strong; weaken them. If the thread tension spring operating range is too large, lower its position as much as possible. Adjust the presser foot pressure if it's too strong. Reduce the sewing speed if it's too fast. Tilt the front of the feed dog down slightly if its angle is incorrect.
Why does my Brother Sewing Machine have skipped stitches at the start?
Skipped stitches at the start may occur if the thread tension spring tensions are too strong; reduce the tension. If the thread tension spring operating range is too large, lower its position. Adjust the pretension if the trailing lengths of the upper threads are too short after thread trimming. Sharpen the fixed knives or replace them if the threads aren't being trimmed cleanly. Try a needle with a count that is one lower if the needle is too wide. Replace the stopper spring in the bobbin case if the length of thread trailing out from the bobbin case is too short after thread trimming and the bobbin is spinning loosely. Use the slow start feature if the sewing speed is too fast at the sewing start. Adjust the synchronizer if the needle up stop position is too high.
How to troubleshoot a Brother Sewing Machine when the lower thread is tangled at the start?
If the lower thread is tangling at the sewing start, ensure the bobbin spins in the opposite direction to the rotary hook when the lower thread is pulled. Make sure the bobbin winding amount is not more than 80%. Attach the free spinning prevention spring. Replace the bobbin if it is not turning smoothly. Use only bobbins specified by Brother.
What to do if my Brother Sewing Machine has uneven seams?
If you're experiencing uneven seams, it might be because the presser foot pressure is too weak, so adjust it. Another cause may be that the feed dog is too low, so adjust its height. Also, check the bobbin for scratches; if it's damaged, smooth it with an oiled grindstone or replace it.
What to do if the oil gauge is not visible in the oil sight glass of my Brother Sewing Machine?
If the oil gauge is not visible in the oil sight glass, fill the oil tank with oil. Check the rotary hook lubrication amount, and adjust the rotary hook lubrication adjusting screw if it is too loose. Replace the oil gauge if it is damaged.
What to do if my Brother S-710A Sewing Machine stops during sewing?
If the machine stops during sewing, check the power supply voltage to ensure it is sufficient.
What to do if my Brother Sewing Machine motor doesn't operate smoothly or makes abnormal noises?
If the motor doesn't operate smoothly or makes an abnormal noise, it indicates a problem with the speed sensor. Replace the motor.
What to do if my Brother S-710A Sewing Machine does not operate when power is on?
If the machine doesn't operate when powered on and the treadle is pressed, ensure the power supply connector is securely connected to the control box. Check the power plug wiring and voltage. Verify that DIP switch No. 8 inside the control box is set to OFF. Also, confirm that the treadle unit connector inside the control box is securely connected.
