Proper Bernina 1000-Series Maintenance: Part 4

Belt Tensioner

Belt Tensioner

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.

If you enjoy this post, you will definitely be interested in reading the previous posts in this series:

Belt Tensioners

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.

I hope you enjoyed this series on Bernina 1000-Series maintenance. Let me know if you have any questions by leaving a comment below.

I would luv to bring my machine to you for repair or check up but I live in West Los Angeles. Can you recommend a Bernina 1000 service location within 20 miles
of West Los Angeles or downtown Los Angeles or Santa Monica that you trust?
Thank you so much!

Sue, I've met all of the dealers at the Bernina dealer meetings, but I don't know them well enough to recommend them. Sorry that I can't answer your question with a response that is more meaningful.
