The Bernina sewing machine is a magnificent wonder in the hands of a competent operator. Its ability to perform intricate tasks is based on the precision with which the machines are assembled. As with any machine with close tolerances, the Bernina requires periodic maintenance and lubrication. Failure to take care of your machine can result in poor performance, jammed mechanisms and the potential to damage it beyond repair. The manufacturer recommends frequent light oiling to maintain top performance.
Make sure the machine is at room temperature. If it has been stored in a cold area, allow the machine to warm for about an hour before oiling it.
Open the top cover and lightly oil all points marked in red. Refer to the owner's manual to ensure you have checked and oiled all the points.
Open the side door and oil all points marked in red. Refer to the owner's manual to ensure you have oiled all the points.
Remove the stitch plate and brush or blow out the fluff that has accumulated there and around the shuttle and the feed dog each time you oil the machine.
Always oil before sewing, never after. Use only high-quality oil free of resin and acid. If you don't have a manual, visit the manufacturer's website for a free download. Follow the manufacturer's recommendations for other maintenance checks each time you oil your machine.
Always wear safety glasses when using compressed air. Remove all needles before cleaning and oiling your machine.
