STEP 9: Let your Bernina Nova dry for about 10 minutes before replacing Bernina face plate and working on it again. You can also use a Bernini cleaning brush kit. Lint is Berninas worst enemy!!! I use my little hand held Bernette on both my bernina nova 900 and my bernina 1007 whenever I’m done sewing to clean out the bobbin area. STEP 8: Cleaning! Get out your vacuum cleaner and go over all visible areas where lint can accumulate. – Bernina sewing machine needle bar – Using a cotton swab, do the same with your Bernina needle bar as you did for your Bernina reverse lever (only use 1 drop of oil here). Too much oil will cause Bernina reverse lever to slip and won’t engage properly. NOTE: The Bernina reverse lever has metal on metal contact, only use a drop or two of oil here. – Bernina reverse lever – Using a cotton swab dipped in light weight machine oil, carefully go around where the 4 screws attach this part so that none of them are dry. Be sure not to over lubricate the hook because excess oil will collect lint! Just be liberal with your oiling and give it 2 or 3 drops. – Bernina hook – A drop of oil here will make your Bernina Nova run like a dream. You can also use Bernette bobbin case grease (I’ve never used this particular grease, but if you want to replace Bernina’s grease with Bernette’s Bernina 930 oil, it works the same) – Bernette bobbin case which holds the bobbins – 3 in 1 Oil or equivalent light weight machine oil. – Bernina screw hole (where the Bernina handle attaches)- 3 in 1 oil or equivalent light weight machine oil, you want something that won’t attract lint over time Here is a list of all of these places and what I recommend using for oiling purposes: There are a few vital places where oil must be applied to keep your Bernina sewing machine working in tip top shape! STEP 7: Now that we have removed the Bernina Nova back plate, you should be able to see your Bernina’s internal workings from here on out. I recommend taking photo’s for reference purposes later if you’re not experienced with Bernina’s. There are particular screws that attach each half of the Bernina to each other in various places, but these are all pretty obvious once you’ve taken out most of your machine’s back cover. STEP 6: At this point we can carefully disassemble our Bernina Nova 900 back into two halves (unfortunately the cord is screwed into one half of your Bernina Nova making it impossible to completely take apart). Unscrew those as well and set them aside so you won’t lose them. It will pull up easily and expose more screws. STEP 5: Now remove the Bernina face plate. At this point, go ahead and remove them with either an appropriate screwdriver or Bernina supplied Bernette screwdriver (again for me, I had misplaced mine after sewing machine college and was using a Bernina 800 screwdriver, which actually fit perfectly! STEP 4: Once you’ve opened up these two side panels, locate all of the visible screws (there should be 5 on each side) that hold your Bernina Nova back plate on. There is likely quite a bit of lint and dirt in this area which you can now take care of! This will allow you to get at some of the screws holding on your Bernina back faceplate. STEP 3: Remove the front of the Bernina Nova 900 by opening the information information cover located on your Bernina’s face plate. Be careful when doing this because there are several springs inside which can pop out if you’re not careful. STEP 2: Remove any dust covers on either side of the machine. Make sure to unplug it, this computerized Bernina will not run without connecting the plug into a working wall outlet! Step 1: Disconnect the electrical cord from the wall outlet and remove any bobbins or projects in progress to prevent accidentally running over them with parts of your Bernina Nova. Here are instructions for cleaning your Bernina Nova 900 sewing machine. The Bernina Nova 900 is an older style Bernina Sewing Machine that uses an external bobbin case, instead of the drop-in type like the newer Bernina models.
