Lint build-up in the hook and feed dog area, as
well as between the top tension disks, can cause
excessive wear, noise and tension problems. Clean
and oil your machine frequently, and your machine
will reward you with trouble-free operation.
In addition, take your BERNINA® machine to an
authorized BERNINA® dealer for an annual check-
up (schedule this during your yearly vacation and
you won’t miss your machine while it’s gone!)
The technician will remove the covers, clean and
lubricate the interior parts, and check the overall
condition of your machine. He/she will also test and
adjust your machine to meet the manufacturer’s
specifications and perform any factory-
recommended updates.
Whille some BERNINA® sewing machines display
a message when it is time to lubricate the hook,
there are times – such as when using linty threads
and fabric – when more frequent cleaning and oiling
is warranted, particularly in machines that have a
rotary hook system.
