Janome offers a number of sewing machines and embroidery machines that have automatic thread cutters. An automatic thread cutter is a very nice feature to have on a machine. Sometimes you can program the machine to automatically cut the thread after locking a stitch, between thread changes, etc. In most cases, you will operate the thread cutter with the touch of a button, just because you want to cut your threads.
Along with other modern functions, the thread cutter is a time saver, and once you start using it, it turns into a “must have” feature. Thread cutters will generally allow you to cut both top and bottom threads, with the touch of a button, and continue sewing instantly. I’ve always been one to hold my threads when I start to sew, but this is not required after using the thread cutter.
For as great and reliable as most thread cutters are, there can be times when they give our customers a hard time. The purpose of this blog post is not just to introduce you to thread cutters, but share how they can be maintained for optimal performance.
If you own a sewing machine with an automatic thread cutter, you may experience issues with its performance. The automatic cutter may have stopped working, or perhaps the cutter works intermittently, but does not work every time. This problem is almost always associated with the thread cutter being clogged with lint. The design of Janome’s automatic thread cutters are fairly simple, but just like a pair of scissors that won’t cut because the blades are loose, lint stuck between an automatic thread cutter’s blades can also keep it from cutting.
This week I worked on a few Janome professional series machines (6500P and 6600P). I took some pictures while I was working on one of them, so you can see the thread cutter. I know that most of you will use a lint brush to keep your sewing machine clean, so make sure to clean the thread cutter as best you can. Q-Tips and tweezers can really help.
The Location of Janome’s Thread Cutter
First, find the thread cutter by taking the needle plate off. You can see it towards the back and left of the hook. There was a lot of lint stuck in the one in the picture below.

Next, I removed the side cover, so you can see the entire thread cutter. There’s a hole in the bottom of the machine, and it allows access to a single screw that holds the side cover on. The cutter is probably a lot bigger than you would expect. It’s held in with two screws.
Cleaning and Oiling The Thread Cutter
I removed the two screws that are holding in the thread cutter, and now you can see the thread cutter outside the machine. I extended the cutter so that I could clean it. I used an air compressor to blast out the lint, and then I cleaned and oiled the cutter before re-installing it.
Now would be a really good time to emphasize that you should consider servicing your sewing machine annually, and if you sew a lot then twice a year. As a Janome dealer, we’ve been to many technical trainings over the years, and know a lot about the machines. Little things like proper lubrication, proper cleaning, and fine tuning can keep your sewing machine sewing like new for many years. If you don’t do the regular maintenance, not only can your machine have problems, but the normal wear and tear increases.
Thread cutters are a wonderful feature on modern sewing machines. They’re a time saver and a luxurious function to have. Sometimes there are performance issues, but if you’re adventurous, you can probably clean and oil your thread cutter.
If you’d like to make sure your thread cutter is cleaned and oiled correctly, bring your machine in to Temecula Valley Sewing Center, or take it to your local Janome dealer.
