I use it on older machines but was told not to use it on these computerized ones!

A Bernina repairman spoke to our guild about machines. He also said never use compressed air. He has seen computers completely clogged with lint. Take off the plate and use brush to clean feed dogs and bobbin casing. He says that's all you need to clean.

I was shown by my dealer to use Q-tips to clean out the dust in the bobbin area. She said never used canned air on a computer machine.
