The key to making perfect stitches on sewing machines like the Juki HZL F300 is proper thread tension and good thread control. One important mechanical part on a machine that assists in this is the take-up lever. This lever is very visible on a machine; however, many people do not actually know what it does.
It is important that sewists understand this lever and all other parts of their Juki sewing machine before starting to sew.
What Does This Lever Do?
The take-up lever is a small metal lever on the front of a machine positioned above the presser foot. This lever moves quickly up and down as you sew, bringing the thread with it as it bobs. Its main purpose is to gently pull the thread from the spool so it can be fed into the needle, then pull the thread back out of the fabric once a stitch has been made.
It plays an essential role in thread feeding, tension, and proper completion of all stitching done on sewing machines. The take-up lever also prevents the bobbin thread from knotting and wadding up on the underside of your project while sewing.
Properly Threading the Take-Up Lever
Threading the take-up lever is part of threading your sewing machine. To do it properly, use the handwheel on your Juki HZL F300 to lift the lever to its highest position, which will also lift the needle to its highest position. The presser foot must also be raised.
After threading the unit through the other guides and around the tension discs, feed the thread through the hole in the take-up lever and pull it through. The last thing to be done is to thread the needle itself. At this point, your machine should be ready to use, with the take-up lever correctly controlling the feed of the spool thread.
Depending upon what type of machine you have and how old it is, the take-up lever may need to be threaded in different ways. On older machines, you will have to thread the loop in the lever by passing the end of the thread through it like you are threading a needle. Most if not all newer machines have a slot opening in the lever that makes threading the lever faster and easier.
When Thread Wads Up
One of the more frustrating problems you may experience when using Juki sewing machines is wadding or nesting of the thread on the underside of the fabric. When this happens, it is a prime indication that there is some sort of problem with the spool thread tension, or that the take-up lever is not threaded.
Troubleshoot this problem by checking to see if the take-up lever is threaded, as this will usually alleviate the problem. If the wadding persists, you should unthread and rethread your machine completely, making sure to properly thread this lever.
The take up lever may seem as if it only performs a very basic job on sewing machines like the Juki HZL F300. Yet this lever is critical to the proper functioning of your machine. This simple mechanical part plays a vital role in guiding your spool thread so that it loops perfectly with the bobbin thread to make a complete stitch. By understanding this and knowing how to troubleshoot thread issues, you can avoid frustrating stitching problems with Juki sewing machines so all of your projects turn out beautifully!
