Though threading a serger sewing machine may seem complicated, it’s actually a simple process that can save you time and energy in the long-run.
There aren’t many items you need to thread a serger sewing machine. Here is a simple list of the items that are generally required for this type of threading.
- Serger Sewing Machine
- Thread Spools
Also, before we begin learning how to thread a serger sewing machine, there are a few helpful tips that will make things a bit easier for you. Let’s take a look!
Before We Begin
Respect the threading order – The order may vary slightly from machine to machine but, usually, it stays the same. You should start with the upper looper, then go on to the lower looper, and then continue with the needles.
Set the thread tensions to zero – Though it isn’t always necessary, it’s generally a good idea to thread your serger machine with the thread tensions set to zero. This allows the wire to rest more precisely within the thread tension control slots. The technique also lets tension build more evenly.
Open the “belly” of the serger – This “belly” is the area that exposes the inside of the thread machine.
Pick up the thread guide pole – Located in the back of the machine, the thread guide pole bobbins work to guide the threads from the bobbins. Forgetting to do this may result in broken threads.
Step 1: Threading the Upper Looper
- First, you’ll want to feed the thread carefully up through the loop of the thread guide. This should be done from back to front. This process is essential when learning how to thread a serger sewing machine.
- Feed the thread under the thread guide. Keep it tight and bring it from right to left. Place it under the thread guide so that it can freely flow.
- Pull it to the left and proceed to step two.
Thread the Tension Slot
- Another method to deal with the upper looper is to hold the thread with your left hand so that it can’t unravel the spool within the slot.
- Then, pass the thread through the guides. These are usually color coordinated and marked on the machine.
Thread Through the Eye of the Upper Looper
- This is a third method for the upper looper. Lift the foot and loosen the tensions. Remember to leave at least 11 cm / 4.3 inches of thread tail.
- Bring the thread toward the rear of the machine, and then under the foot, and finally to the left.
- Lower the foot. This should complete the threading of the upper looper. Then, you can continue with learning how to thread a serger sewing machine and move on to the next looper.
Step 2: Threading the Lower Looper
After following the upper looper instructions, begin feeding the lower looper guides. They should be drawn somewhere on the machine and will be coded with corresponding colors.
Thread the Eye of the Upper Looper
- After lifting the foot and loosening tension, move the right knob and position the lower looper above the upper one.
- As before, leave at least 11 cm / 4.3 cm of thread tail. Bring the thread tail toward the machine’s rear and then under the foot and to the left.
- Lower the foot.
Step 3: The Needles
- First, move the right knob. This will help you to better expose the eye of the needle making it easier to thread and bringing it to a higher and more convenient position.
- Thread through the guide and tension slots.
- Allow the guide and tension slots to pass together through the thread slots.
- Keeping your right thread with the right needle and your left thread with your left needle, thread the needles.
- Bring the two tails toward the rear of the serger and under the foot. Then guide them to the left and have the tails come up from the loopers. As before, you should have at least 11 cm / 4.3 inches of tail available to pull.
- Pull the threads from behind the respective guides located at the top, positioned above the needles.
Step 4: Arrange Tensions
- Arrange the tensions accordingly. You’ll want to adjust for the type of fabric you are intending to sew. This is, again, an important step in learning how to thread a serger sewing machine.
- The type of stitch you’re planning to use may also impact the tension. Use your machine’s user manual to determine which tension settings will be most appropriate.
Step 5: Begin Sewing
- You should now be ready to begin sewing! Gently place your foot on the pedal control and insert the fabric. Lightly apply pressure to see if your thread remains intact.
- If the thread breaks, you may have done something incorrectly. Start from step one, and adjust the tensions accordingly.
- If the thread does not break, you’re done and can get started on your next sewing project. Great job!
Other Things to Consider
Here are a few more key points that you should take into consideration when learning how to thread a serger sewing machine.
- Brand specifics – Depending on the brand of your serger machine, the threading process can vary. If you are choosing an off-brand version of a popular model, the threading process will likely be similar if not identical to the brand you’re using.
- Models may differ – Keep in mind than serger sewing machines can vary from model to model, even within a specific brand. This is uncommon, but it may be a good idea to look up your specific sewing machine model online before you begin threading. This way, you can make sure you don’t miss critical steps or get confused during the threading process.
This is one of the easiest ways to learn how to thread a serger sewing machine. If you respect the steps, things should not be that complicated. You should start with the upper looper, then move to the lower looper and, in the end, deal with the needles. Also, don’t forget to check if your thread holds before starting to sew.
