What to do if the upper thread is not cut on my Brother BAS-342H?
If the upper thread is not being cut, the movable knife may be blunt and needs replacement, or the fixed knife may be blunt and needs sharpening or replacement. The movable knife might not be picking up the upper thread, requiring a timing adjustment. You might need to adjust the standby position of the movable knife. Refer to 'Skipped stitches occur'.
Why is the pattern distorted on my Brother BAS-342H Sewing Machine?
If the pattern is distorted, it may be because the work clamp and feed plate are too heavy. If you are using heavy work clamp and feed plate, change the operation settings to the settings for heavy-weight materials.
Why is the work clamp pressure not uniform on my Brother BAS-342H?
If the work clamp pressure isn't uniform at the front and back, the work clamp may be tilted. Adjust the tilt of the work clamp.
Why doesn't the work clamp rise to the maximum height on my Brother BAS-342H Sewing Machine?
If the work clamp doesn't rise to its maximum height, the work clamp lifter lever position may be incorrect. Adjust the position of the work clamp lifter lever.
What to do if the lower thread is not cut on my Brother BAS-342H?
If the lower thread is not being cut, it may be because the lower thread tension is too weak. Increase the lower thread tension.
Why is the work clamp pressure too weak on my Brother Sewing Machine?
If the work clamp pressure is too weak, the air pressure may be too weak. Adjust the regulator so that the air pressure is about 0.5 MPa.
Why is there a poor seam finish on the underside of the material at the sewing start with my Brother BAS-342H Sewing Machine?
A poor seam finish on the underside of the material at the sewing start can occur if the upper thread trailing length is too long. Adjust the sub-tension so that the upper thread trailing length after thread trimming is approximately 42 mm.
What to do if the work clamp does not work on my Brother BAS-342H Sewing Machine?
The work clamp may not function if the air cock is closed; open it. If the air pressure is too weak, adjust the regulator to approximately 0.5 MPa. If the speed controller has been tightened too far, loosen it 4 turns from the fully-tightened position.
What to do if thread wiper does not operate correctly on Brother BAS-342H Sewing Machine?
If the thread wiper isn't working correctly, it could be obstructing the needle, in which case you should adjust its height. Adjust the operating stroke of the thread wiper. The thread wiper position might be incorrect, so adjust the operating stroke of the thread wiper.
Why is the upper thread breaking on my Brother Sewing Machine?
If the upper thread is breaking, it could be due to several factors. Make sure the thread isn't too thick for the needle; if it is, select a suitable thread. Ensure the needle is installed correctly and the thread is threaded correctly. Damage or burring in parts like the rotary hook, needle hole plate, needle, or thread path can cause breakage; repair these parts by buffing. Incorrect needle and rotary hook timing requires timing adjustment. If the upper thread tension or thread take-up spring tension is too strong, reduce it. If the thread breaks due to heat, consider using a needle cooler unit or reducing the sewing speed.
