How To Service A Bernina Sewing Machine


A Bernina sewing machine is an invaluable tool for crafters and sewers everywhere. It’s no wonder that Bernina sewing machines are amongst the most sought-after sewing machines on the market. Whether you’re new to sewing, or are an experienced tailor, you’ve probably heard about the many benefits of using a Bernina Sewing Machine. However, it is important that you know how to service your machine in order to keep it running the way it should. This article will provide important information about how to service a Bernina Sewing Machine, as well as some helpful tips and tricks.

Cleaning and Oiling the Machine

The most basic maintenance for a Bernina sewing machine is cleaning and oiling. This should completely be done on a regular basis, depending on the frequency with which it is used. If the machine is used frequently, you may need to clean and oil it more often. To begin cleaning, make sure to turn the machine off and unplug it. Then, use a soft cloth or brush to remove any loose threads, dirt or oil from the machine’s exterior. Be careful not to use any harsh cleaning agents, as they could damage the exterior of the machine.
Next, you must oil the machine’s internal components. You can find the exact oil you need at your local sewing supplies or crafts stores. Take off the machine’s cover and carefully oil the moving parts, taking care not to get the oil on the machine’s exterior. It is also important to make sure that the needle bar and its components are properly lubricated. It is recommended that you never use motor oil, as it could cause problems for your machine.

Checking the Machine for Worn Parts

After you’ve cleaned and oiled your machine, you will also need to check it for any parts that may be worn or need replacing. Start by visually inspecting the machine, looking for any indicators of wear such as frayed threads, broken parts, or any rust. Next, test the machine by stitching a large amount of fabric to ensure it is working properly. If there are any issues with the stitches, you may need to replace some of the parts or take it to a technician.

Replacing the Needle

For best performance, the needle of the Bernina Sewing Machine should be replaced on a regular basis. If the needle is showing signs of wear, such as scratches or burrs, it is likely that it needs to be replaced. As always, ensure that the machine is unplugged before beginning any work.
Once the machine is unplugged, use scissors to snip off any loose threads that may be stuck in the needlebar. Then, remove the old needle by loosening the screw in its base. Before replacing the needle, be sure to check that the needle size is correct for the type of fabric you are working with, as well as its point. After inserting the needle, firmly tighten the screw and test the machine out on a swatch of fabric.

Testing the Tension

On a Bernina sewing machine, tension is a very important component. If this setting is not adjusted properly, then the stitches may unravel or become malformed. To ensure accurate tension, you should test the stitches on a swatch of fabric. Begin by adjusting the tension until the stitches are uniform and consistent throughout the piece.
Once you have finished testing the tension, it is important to note down the particular tension setting for future reference. This way, whenever you are ready to work with the same type of fabric, you can easily adjust the tension accordingly.

Troubleshooting Common Problems

As with any sewing machine, the Bernina Sewing Machine is subject to certain problems and issues, such as thread jamming, needle breakage, and skipped stitches. Thankfully, there are certain steps that you can take to troubleshoot and fix these problems.
One of the most common issues is thread jamming, which is usually caused by a number of factors, including incorrect thread tension or incorrect thread path. You can usually resolve this issue by following the steps outlined in your machine’s manual.
If your Bernina sewing machine is skipping stitches, it could mean that the hook or needle is worn and needs to be replaced. Once you have identified the cause of the skipping stitches, you can replace the worn part and adjust the tension accordingly.

Useful Tips for Servicing a Bernina Sewing Machine

Servicing and maintaining a Bernina Sewing Machine is not difficult, however there are some helpful tips that you should keep in mind.
First, it is important to make sure that the power is off when you start cleaning and servicing the machine. This is a basic safety measure that should always be followed.
Second, always be sure to check the manufacturer’s manual for specific instructions. This way, you can be sure that you are following the correct steps when servicing the machine.
