In this Instructable I am going to show you a simple way to keep your machine working in tip top shape.
At TechShop San Jose, we have Janome home sewing machines
Be sure your presser foot and needle are raised as high as possible so you don't damage them. You could also choose to remove them completely if your presser foot or needle don't lift out enough for you to reach all the parts you need.
Next, unscrew and remove the needle plate. Your needle plate may have more screws, so make sure you get them all before trying to lift it.
Lint is your machine's worst enemy and plays a big part in any sewing machine's malfunctioning.
You can use either a soft bristled brush, a soft cleaning cloth, or compressed air to get all the lint out.
When you look into the center of the bobbin raceway, you can see a series of metal circles which are the bobbin's bearings. In the middle of these bearings is usually a small sponge.
Place a few drops of sewing machine oil on this center sponge. You want to make sure you get enough in there to oil the machine, but don't overfill it to the point where oil is pooling out of the center circle.
1) Replace the bobbin holder
2) Reattach the needle plate
3) Insert bobbin and bobbin cover
This simple maintenance done once a month should keep your machine working for years.
