There are several reasons why it is important to put oil on the slots of a sewing machine after dusting it.
1. Lubrication: Sewing machines have many moving parts, such as the needle bar, presser foot, and bobbin case, that need to move smoothly in order for the machine to function properly. By applying oil to the slots of the machine, you are ensuring that these parts are lubricated and able to move freely without getting stuck or causing friction.
2. Preventing rust and corrosion: Sewing machines are made of metal, which can rust and corrode over time if not properly maintained. By applying oil to the slots of the machine, you are creating a barrier between the metal parts and the air, which helps prevent rust and corrosion from forming.
3. Extending the life of the machine: Regular maintenance, such as oiling the slots of the sewing machine, can help extend the life of the machine. By keeping the moving parts lubricated and preventing rust and corrosion, you are ensuring that the machine will continue to operate smoothly and efficiently for years to come.
4. Improving performance: A well-maintained sewing machine will perform better than one that is not properly cared for. By oiling the slots of the machine, you are helping to keep the machine in optimal working condition, which can result in better stitch quality and overall performance.
In conclusion, oiling the slots of a sewing machine after dusting it is an important step in maintaining the machine and ensuring that it continues to operate smoothly and efficiently. By taking the time to properly care for your sewing machine, you can extend its life, improve its performance, and prevent costly repairs in the future.
