This post is the last in a series on proper maintenance of 1000-Series Bernina sewing machines. It isn’t that I expect you to be tearing down your sewing machine and performing your own annual services, but just to make you aware of what is done, and what should be done.

There is at least one, but sometimes two belt tensioners in a Bernina 1000-Series machine. In either case, the belt tensioner is responsible for keeping the belt tight, so that it doesn’t skip a tooth and throw off the timing of the machine. While the tension may need to be adjusted, there is a more common problem associated with belt tensioners, which is that they may seize due to lack of lubrication.
Belt tensioners have been known to make some sharp squealing, squeaking, and chirping type sounds when they lack lubrication. They may even completely stop rotating, at which point they may cause belt damage. Any Bernina machine brought to Temecula Valley Sewing Center has it’s belt tensioners taken out of cleaning and lubrication.
