If your JUKI HZL-DX7 sewing machine's automatic thread cutter is leaving behind a short piece of thread in the mechanism after each cut, there might be a few potential causes for this issue. Here are some steps you can take to troubleshoot and address the problem:
Thread Tension: Check the tension settings for both the upper and lower threads. Improper tension can cause thread to be left behind in the thread cutter mechanism. Make sure the tension is balanced and appropriate for the type of fabric you're sewing.
Thread Quality: Poor-quality or thick threads can sometimes get caught in the thread cutter mechanism. Ensure you're using good-quality threads that are suitable for your sewing project.
Thread Path and Thread Guides: Make sure the upper and lower threads are properly threaded through the machine's threading path and guides. Improper threading can lead to thread buildup in the cutter area.
Thread Cutter Mechanism Cleaning: The thread cutter mechanism might have accumulated lint, debris, or bits of thread over time. Gently clean the thread cutter area with a small brush, compressed air, or a vacuum cleaner to remove any buildup.
Blade Inspection: Check the blade of the thread cutter for any nicks, dullness, or damage. A damaged blade might not cut the thread cleanly, leaving behind remnants.
Thread Cutter Mechanism Lubrication: Some sewing machines have small moving parts in the thread cutter area that benefit from occasional lubrication. Consult your sewing machine's manual to see if lubrication is recommended and use a sewing machine-safe lubricant if needed.
Machine Maintenance: Regular maintenance of your sewing machine, including cleaning and oiling as recommended in the manual, can help prevent issues with the thread cutter mechanism.
Consult the Manual: Refer to your JUKI HZL-DX7 sewing machine's manual for specific instructions on troubleshooting and maintaining the automatic thread cutter.
Professional Service: If the issue persists after trying these steps, it might be best to seek the assistance of a professional sewing machine technician. They can diagnose and repair any mechanical issues with the thread cutter mechanism.
Remember that working with sewing machines involves mechanical parts and electrical components, so it's important to follow safety guidelines and, if needed, seek professional assistance to avoid causing further damage or harm.
If your Juki HZL-210 Excite's automatic thread cutter is cutting your thread when you're trying to straight stitch, there are a few things you can check:
Make sure you're using the correct presser foot: If the wrong presser foot is installed, it can activate the automatic thread cutter when you don't want it to. Ensure that you're using the appropriate presser foot for your straight stitch.
Check your thread tension: An incorrect thread tension can also cause the automatic thread cutter to activate at the wrong time. Make sure your thread tension is properly set for the type of fabric you're using and the type of stitch you want to make.
Clean the machine: Accumulated lint or debris can cause the automatic thread cutter to malfunction. Use a brush or compressed air to clean the machine, particularly around the thread cutter mechanism.
Reset the machine: Turn off the machine and unplug it for a few minutes, then plug it back in and turn it on again. This can sometimes reset the automatic thread cutter and resolve any issues.
If none of these solutions work, you may need to take your machine to a professional for servicing or repair.
Has a piece of broken needle or chunk of thread jammed into the blades and are not letting them move? If there was a big time thread jam it can actually break one of your blades and you will have to go to a repair man and have the blade replaced.
