Instructions
for cleaning and oiling the Bernina
I've been a professional seamstress for 49 years, and this has been my main machine for the past 36 of them. I suppose she's had over 700,000 yards of fabric run under her needles in that time, and she still works great. Of course, my machine is used on a regular basis, but I've also taken the time to take care to clean and oil it frequently. The fantastic Swiss design features on this model, the last, all-metal machine made by Bernina, make these maintenance chores easy to achieve.

1. Open the door covering the
bobbin area.
2. Press the second lever from
the top on the left hand side to release the ‘door’ that holds the shuttle and
the bobbin case in position.
The shuttle, which is the metal
thing with the holes in it, will fall forward. The shuttle may still be holding
to the bobbin case if you have not yet removed it.
3. Using a machine cleaning
brush, sweep away any lint or tiny threads in the area, moving the brush away
from the machine.
4. Wipe the shuttle area clean
with a scrap of sheet, or other material that does not have fuzz on it.
The bobbin case is on the left,
the shuttle is on the right.
5. Turn the SHUTTLE itself
upside down, wipe it off, and add a single drop of oil.
6. Using your finger tip,
spread the machine oil across the outside bottom of the shuttle and around the
outside ridges of it. You can also run your oiled finger around the metal chamber in the machine into which the shuttle fits.
7. Place the shuttle back into
the casing, and close the door mechanism that holds it in place.
I’m pushing the ‘door’ that
holds the shuttle back into place closed. It clicks audibly when in the closed position.
8. Next, using the lever inside
this same area that is closest to the top of the machine on the left
side, release the cover that forms the bed of the machine’s arm.
9. Again, use the brush to
remove any loose particles, dust or threads.
10. Looking down into the arm,
slowly run the machine for a few moments and visually note which parts move.
Some will slide, piston-like, and others will partially rotate.
11. Add a TINY drop of machine
oil at each point of movement of all the components of this section of
the machine.
The copper-colored ‘rod’ you
see here is a long tube that extends from my oil bottle to dispense a drop of
oil on one of the contact points.
12. Replace the arm cover by
sliding it from the needle end, in towards the right side of the machine, and pushing
down on it until it clicks back into place.
13. Next, turn the machine so
that the end that holds the needle faces you.
14. Open the door covering the
mechanics above the needle. It hinges on the rear side of the machine.
15. Sweep or wipe away any
dirt, fuzz or threads.
16. Run the machine for a few
moments, noting which sections of the machinery move.
17. Place a TINY drop of oil at
each friction and movement point on the machinery.
18. Wipe off any residual oil
so it does not run down onto the needle.
19. Close the door.
20. Stitch for a few moments on
a scrap of fabric, to make certain there is no oil remaining to stain your good
fabric.
