What Goes Into a Tune-Up?
1. Disassembling the covers in preparation for the tune-up. Notice the red
mat that the machine is resting on and the wrist band that Carolee is wearing. The mat and wrist
band ground the workbench and technician to dissipate any latent static
electricity which could damage the machine's circuit boards while they are separated
from the machine.
3. One of many mechanical parts being removed in preparation for
cleaning.
2. Carbon debris accumulation inside the cover. The carbon debris is
removed during the tune-up to avoid contaminating the lubrication in
the mechanics of the machine.
4. Initial cleaning of the machine skeleton with compressed air.

5. Manual removal of stubborn threads, lint and fuzz which could not be
dislodged during the compressed air cleaning.
6. The bobbin hook system is disassembled for cleaning. Those little black
dots aren't debris from the machine. They're actually teeny-tiny screws!
7. Look at the burnt oil cleaned from this integral pulley system.
Virtually every movement in the machine is dependent upon the function of
this pulley. Should the pulley become too soiled or the oil become
excessively burned, the entire machine could seize, causing irreparable
damage.
8. In case it isn't obvious yet, let us point out that our expertise
does not extend to photography! You'll just have to trust us when we say
that this is a photo of Carolee re-tensioning the belts after the cleaned
and lubricated pulley has been reinstalled.
10. Old, soiled grease and oil are removed from the mechanical parts
in the front and back of the machine. Notice the old, black grease on the end of
the cleaning tool.
11. Fresh, Bernina grease is reapplied to the appropriate areas of the
machine.
12. Light-weight oil is applied to other mechanical parts. Carolee and
Stephanie know exactly what to apply where.
13. The bobbin case is disassembled, inspected and thoroughly cleaned.
14. More evidence of our photographic skills (or lack thereof). You'll have
to trust us again when we say that Carolee is calibrating the
tension on the cleaned and reassembled bobbin case with a Bernina counterweight.
15. The bobbin hook system has been reinstalled and the machine has been
re-timed. Carolee is performing a bobbin system
calibration with special Bernina gauges to ensure the best quality stitch formation.
16. Cables are reconnected to the circuit boards when the machine is put
back together.
19. A final test-sew ensures that the machine is sewing at its peak.
18. The machine housing is thoroughly cleaned.

9. The upper thread path is inspected, cleaned of stray threads, and
the tension disks are recalibrated.
17. The feed dogs are checked with a special Bernina gauge to ensure that they are at the proper
