Let’s face it, most people don’t bring in their sewing machine for annual services. Many don’t even clean their machine in between services! This post will cover the simple cleaning that an owner of a Bernina sewing machine should be doing between services, and is specifically for Bernina machines with oscillating type hooks. If you don’t have a Bernina machine with an oscillating hook, you will not be able to take your hook out for cleaning, however, your machine may still benefit from some of the steps described, so please keep reading.
Take Off Your Needle Plate
The first thing to do is remove your needle plate. On 1000 series machines, you will need to lower your feed dogs, lift the front edge of the needle plate, and then slide the needle plate backwards. Many machines, like the 830 or 930 require that you release the needle plate by pushing a latch. On most newer machines, you can simply press the rear right corner of the needle plate down, and the needle plate will pop up for removal. As you remove your needle plate, take a look at how it is aligned so that re-installation is easier.
Brush Off The Feed Dogs
All Bernina machines come with a lint brush, so take out your brush and clean any lint from the top of the feed dogs. Lint may be packed into the feed dog, so don’t be afraid to use something to get that lint out. Here in the TVSC service department, I use a pick tool that looks a lot like a dental pick. Rather than brushing, you might try to vacuum out the lint. Just don’t use canned air or an air compressor, because you would probably blow lint back in to the machine, which is bad.
Remove Bobbin Case And Hook
You should all know how to remove your bobbin case, and if you don’t, cleaning your machine is going to have to wait for a few minutes! Take the bobbin case out of the machine. The post that your bobbin case was attached to is part of the hook. Push the latch that is located directly to the left of where the bobbin was to open the hook door. Be careful; in some machines pushing the latch in a direction that is not directly left can result in damage to the latch. The latch shouldn’t require great force to release the hook door, so if you are pressing the latch really hard, you should stop and bring your machine to us so that we can show you what to do. If you successfully pressed the latch, then the hook door will pop forward, and you will be able to remove the hook. Note how the hook is aligned.
Remove Lint From Hook Race
With your thumb and forefinger, remove the hook by grasping the post that the bobbin case snaps on to, and pull it towards you. This hook oscillates in a recessed groove called the hook race, and this area is generally the dirtiest part of any sewing machine. Use a tool like a toothpick or dental pick and remove any lint from the hook race. When you are done with the big stuff, use a q-tip with a little oil on it, and swipe all the surfaces of the hook race. You will notice that the q-tip gets quite dirty, so don’t be afraid to use more than one to clean up the area.
Oil Hook Race and Hook
You most likely applied enough oil to the hook race just by cleaning it, but if it makes you happy, you can put a drop of oil directly on the hook race. The outer edge of the hook itself is a good place to oil, and if you see any link on the hook you should remove it now.
Re-install Hook, Bobbin, and Needle Plate
Take your clean, oiled hook, and put it back in the hook race. It only goes in one way, so take your time and make sure it goes in just how it was before your took it out. It may be easier for some people to lay their machine on its back for this step. Once you have the hook placed in the hook race correctly, close the hook door until the latch makes a click sound. You can now put your bobbin back in, and reinstall your needle plate.
Most owners manuals will cover the cleaning of your machine, but they may not provide enough detail for you to do it effectively. If you use your manual in conjunction with these instuctions, it shouldn’t be hard to clean your machine between services. If you still don’t feel comfortable doing this, then you can make an appointment with us, and we will clean your machine for you. Keeping your machine clean will help your machine last for a long time, and it will sew better!
