How To Oil Singer 4423 Sewing Machine

Prepare your machine

The first step in learning how to oil a Singer 4423 sewing machine is to prepare the machine for oiling. Begin by turning off the power switch, or unplugging the machine from its electrical connection. Remove the needle plate cover from the machine. Use a Phillips or flat head screwdriver to remove any screws that may be holding the plate in place. Once the plate is removed, set aside any sewing equipment or items that could become a hazard if oil were to come in contact with them.

Check the oil level

The next step when oiling your Singer 4423 is to check the oil level. Inspect the main parts of the machine including the exterior, the sewing arm, the dangling feed needles, and the bobbin area and their oil levels. The exterior should have an oil port that can be easily seen. The next is the sewing arm, which should feel and smell lubricated. Finally, move on to the bobbin area and feed needles; they should be well-oiled.

Clean and brush out old oil

Before adding any new oil to the machine, it’s important to clean and brush out any old or used oil that is currently in the machine. This is done using the brush attachment for the machine and a nearby dustpan. Brush thoroughly in all parts of the machine and make sure that all old oil is entirely gone.

Apply the oil

When the machine has been sufficiently cleaned and wiped, it is time to apply the oil. Singer recommends using only high-grade sewing machine oil for the machine. Start with the exterior, or oil port of the machine. Insert the nozzle of the oil into the port and give it a few squeezes until the exterior begins to feel well lubricated. Once the exterior is done, move on to the interior.

Interior oiling

The next step is to oil the interior parts of the machine. Begin by oiling the sewing arm, making sure to get oil into all the crevices. Sprinkle oil in the bobbin area and drop some oil into the feed needles. Be careful not to over-oil the machine, and make sure you are oiling the right parts. Remember to use the brush attachment to wipe away any excess oil.

Test machine

After your Singer 4423machine is oiled, it is important to perform a test to make sure it is running properly. Plug in the machine and turn the power switch on. Sew a few stitches, and also test the bobbin area to make sure the tension is even. If the machine runs without any issues and all parts are working properly, then the oiling process was a success.

Frequency of oiling

It is recommended to oil your Singer 4423 sewing machine after every 20 hours of use. This would vary depending on the type of work that you are doing, but it is best to check and make sure all parts are oiled and lubricated. This will help keep your machine running smoothly and increase its longevity.


When storing your Singer 4423 sewing machine, it is important to make sure it is in a clean and dry environment. It is also important to make sure the machine is packed away securely to avoid any further damage. This includes covering the machine with a fabric or cloth, making sure it is closed securely, and stored in a safe place.


In order to keep your Singer 4423 sewing machine running in optimal condition, it is important to perform regular maintenance activities. Clean the machine frequently using a soft cloth and a brush to get rid of any dirt or built-up dust. Make sure to oil the machine at least once every 20 hours of use. Inspect the machine for any signs of wear or damage and address any issues immediately.

Extra safety precautions

When oiling your Singer 4423 sewing machine, it is important to take extra safety precautions. Make sure that the area where you are working is clear of any debris and hazards. Wear protective gloves and make sure you are using the right type of oil. Be careful not to over-oil the machine by following the instructions closely.
