Hi, I've had my Husqvarna Sapphire for 830 for a while now and find it's really noisy. It sews ok, but the noise is pretty loud for an electronic machine. Anyone else experience this? I used to be able to open and clean and oil my old Brother and Janome machines, but this one will only let you open the shuttle case and remove any lint with tweezers. Not a simple process. Any suggestions??
