Various stitching that creates beautiful clothing is made easy with the presence of sewing machines. With a perfect cut and perfect thread color, coupled with an appropriate needle, creating the design that you like is easy to achieve. Investing in sewing machines is really worth your money, however getting the best out of the unit is only made possible with proper care and maintenance by the owner. Although the machine looks complicated, maintaining it is actually very easy. Here are the steps on how to increase the life of your sewing machine: • Take a tour of the machine first. Identify common parts, which are exposed when sewing. • While sewing, it is inevitable that excess thread and fiber particles stick to the interior of the throat plate. Free the throat plate of thread, lint and batting, as this may interrupt smooth sewing and damage your machine. • Fibers that stick inside the plate should be carefully removed, because they have a tendency to become lodged further towards the interior of the plate. This can be accomplished by using a brush to sweep the fibers, rather than blowing on them. Blowing can introduce moisture, which can cause rusting of the unit. • The use of a vacuum nozzle has also been helpful in removing very fine fiber particles not taken out with brushes, especially in those-hard- to reach areas. • The bobbin case and hook should be maintained as well by wiping off dust and particles using a soft cloth. Excess oil spilled over these parts can be eliminated in the process. • Frequent addition specially designed gear oil for sewing machines also improves the movement of the wheels and prevents it from hardening. Cleaning your sewing machine will help increase its usability, and therefore you are getting your money's worth for a longer period of time. Doing so will also increase ease in sewing and reduce money needed for repairs.
