Bernina 830 & 930; Don't Try These At Home!


Bernina 830 & 930
PROBLEMS YOU PROBABLY SHOULD NOT TACKLE ON YOUR OWN


Unbalanced Buttonhole- If stitch density on one side of the buttonhole is tighter or looser than the other side, and you are using the correct foot and technique. This is a very painstaking adjustment that requires a special tool.

Machine is dead- If your machine’s light works OK, but the machine will not run, you probably will want to take it to a service person who can diagnose the exact problem. It’s expensive to replace parts at random.

Motor Noises- Any unusual noise (buzzing, growling, squeaking, grinding, etc.) is indicative of a problem that is not just going to go away. It will probably get worse although you may continue to use it for some time.

Major Breakage- It is very common for a machine to fall off the table, be damaged in transit, or meet with some other misfortune. If a major body part, such as the handwheel, bobbin winder, take-up lever, pressure lifter, etc. is broken, then it’s a job for a repairman.

Tight Spot- When turning the machine by hand, if it gets suddenly tighter at the same spot in its revolution, and there is not thread caught around the take-up assembly or handwheel, then the news could be bad.

Timing- When the upper thread will not loop around the bobbin or pull up the bobbin thread, or a new straight needle hits or catches something down in the machine then it’s usually a "timing" problem. There are several interrelated adjustments to be made in this event, and I do not believe it should be tried at home. The potential for doing more damage is too great for someone without experience in sewing machine repair.

Where can I buy a bernina sewing machine in Orlando, FL? I am trying to find one for my grandma because she needs a new one.

Any suggestions on a needle position knob that won't work? IT will not turn to the left at all, but will turn to the right, but springs back.
Thanks
