What to do if my Brother S-7200C is trimming thread incorrectly?
If both upper and lower threads are not being trimmed, the fixed knife or movable knife may be damaged or worn. Replace the fixed knife or the movable knife.
What to do if my Brother S-7200C Sewing Machine is skipping stitches while sewing?
Skipped stitches can occur for several reasons. The needle tip might be bent or blunt, the needle may not be properly installed, or the machine might not be correctly threaded. The presser foot pressure could be too weak, or the needle might be too thin. Also, the presser foot could be too high, the thread take-up spring could be too weak, or the needle and rotary hook timing might be off. Replace the needle if it is bent or broken, install the needle correctly, and thread the machine correctly. Adjust the presser foot pressure, use a thicker needle, adjust the height of the presser foot, and adjust the tension of the thread take-up spring. Also, adjust the height of the needle bar and the clearance between the needle and the tip of the rotary hook.
What to do if the oil gauge is not visible in the oil gauge window of my Brother Sewing Machine?
If the oil gauge is not visible, the oil tank may be empty. Fill the oil tank with oil.
What to do if my Brother S-7200C Sewing Machine does not operate when turned on?
If the machine does not operate when turned on, the power supply connector may be disconnected from the control box. Insert the connector securely.
Why is my Brother S-7200C Sewing Machine producing an uneven seam?
An uneven seam may be due to weak presser foot pressure, a feed dog that is too low, or a scratched bobbin. You can adjust the presser foot pressure and adjust the feed dog height. If the bobbin is damaged, smooth it or replace it.
How to fix skipped stitches at the start of sewing with my Brother Sewing Machine?
Skipped stitches or thread unravelling at the start of sewing can occur if the thread take-up spring tension is too strong or its operating range is too large. It can also happen if the trailing lengths of the upper threads are too short after thread trimming, the threads are not being trimmed cleanly, the needle is too thick, the length of thread trailing out from the bobbin case after thread trimming is too short, the sewing speed is too fast, or the needle up stop position is too high. Reduce the tension of the thread take-up spring and lower its position. Adjust the pretension. Sharpen or replace the knives. Use a thinner needle. Replace the anti-spin spring in the bobbin case if the bobbin is spinning loosely. Use the slow start feature and adjust the needle up stop position.
What to do if my Brother S-7200C does not operate at high speed?
If the machine does not operate at high speed, the sewing speed setting or backtack speed setting may be incorrect. Use the sewing speed control keys to set the high speed.
What to do if my Brother S-7200C is trimming thread incorrectly (upper or lower thread)?
If the upper or lower thread is not being trimmed, it may be that the needle is not properly installed, or the fixed knife or movable knife is blunt. Install the needle correctly and replace the fixed knife or the movable knife.
What causes material slippage on my Brother S-7200C?
Material slippage can occur if the presser foot pressure is too strong. Adjust the presser foot pressure.
Why is the lower thread tangled at the sewing start on my Brother S-7200C?
Tangled lower thread at the sewing start can occur if the bobbin spinning direction is incorrect when the lower thread is being pulled, there is too much thread wound onto the bobbin, the anti-spin spring is not attached, the bobbin is not turning smoothly, or a bobbin other than the light-alloy bobbins specified by Brother is being used. Set the bobbin so that it turns in the opposite direction to the rotary hook. Ensure the bobbin winding amount is not more than 80 %. Attach the anti-spin spring. Replace the bobbin if it is not turning smoothly and use only bobbins which are specified by Brother.
