Why is the lower thread not tight on my Brother Sewing Machine?
The lower thread might not be tight because the lower thread tension is too weak, or the upper thread tension is too strong. Adjust the lower thread tension or upper thread tension.
What to do if Brother Sewing Machine has skipped stitches at sewing start?
To address skipped stitches and thread unravelling at the start when using your Brother Sewing Machine, try the following: reduce the tension of the thread take-up spring and lower its position. Adjust the pretension if the trailing lengths of the upper threads are too short after trimming. Sharpen or replace the knives if threads aren't being trimmed cleanly. Use a thinner needle if the current one is too wide. Replace the anti-spin spring in the bobbin case if the thread length is too short after trimming, or if the bobbin is spinning loosely. Use the slow start feature if sewing speed is too fast, and adjust the needle up stop position if it's too high.
What to do if skipped stitches occur while sewing with my Brother S-7200B?
If you are experiencing skipped stitches while sewing, consider the following: * A bent needle tip can cause this issue, so replace the needle. * Ensure the needle is properly installed. * Make sure the machine is correctly threaded. * The presser foot pressure may be too weak; adjust it accordingly. * A needle that's too thin could be the problem; replace it with a slightly thicker one. * If the presser foot is too high, adjust its height. * The thread take-up spring might be too weak; adjust its tension. * The needle and rotary hook timing must be correct; adjust the needle bar height and the clearance between the needle and the rotary hook tip.
What does Err 6 (Voltage drop) mean on my Brother Sewing Machine and how to fix it?
The Err 6 error code indicates a voltage drop. If the power was turned on while the treadle was depressed, return the treadle to the neutral position and then turn on the power switch. Also, check the power supply voltage to ensure it is adequate.
What causes a large degree of puckering (excess tension) when using my Brother S-7200B?
Excessive puckering can be due to several factors: * The upper thread tension may be too strong; weaken it. * The lower thread tension may be too strong; weaken it. * A blunt needle tip can cause puckering; replace the needle. * A needle that's too thick could be the issue; replace it with a thinner one. * The thread take-up spring tensions may be too strong; weaken them. * The thread take-up spring operating range may be too large; lower its position. * The presser foot pressure may be too strong; adjust it. * The sewing speed may be too fast; reduce it. * The angle of the feed dog may be incorrect; tilt the front down slightly.
What does “GrEASEUP” or “GU” flashing on the panel display of my Brother S-7200B mean?
Apply grease.
What causes material slippage on Brother Sewing Machine?
If you're experiencing material slippage with your Brother Sewing Machine, adjust the presser foot pressure.
Why are there loops in the seam of my Brother S-7200B?
If loops appear in the seam of your Brother Sewing Machine, polish the thread path with a fine-grain file or sandpaper if it's not smooth enough. If the bobbin isn't turning smoothly, check for slackness in the thread tension, or replace the bobbin or bobbin case.
What does Err 1 (Overvoltage) mean on my Brother S-7200B and how to fix it?
The Err 1 error code indicates an overvoltage issue. Check if the power supply voltage matches the control box voltage specifications. Also, verify if the power supply voltage is abnormally high. If problems persist, the control box may need to be replaced.
What to do if my Brother S-7200B Sewing Machine is producing an uneven seam?
An uneven seam can result from several factors: * If the presser foot pressure is too weak, adjust it to provide adequate pressure. * If the feed dog is too low, adjust its height to ensure proper fabric feed. * A scratched bobbin can also cause issues; smooth it with an oiled grindstone or replace it.
