How To Open A Pfaff Sewing Machine Correctly
Before anything else, please refer to the Pfaff manual of the specific model you have. Read the illustrations so you’ll be familiar with your unit’s anatomy.
Step 1. Remove the top cover
- Place a towel over the surface where you’ll open the sewing machine to prevent screws from bouncing off and getting lost
- Prepare several ziplock bags to organize the screws for each plate; a helpful tip is to tape the bag of crews on each cover where you removed them
- Locate the screws at the front of the Pfaff sewing machine on top of the needle and remove them
- Move the spool holder to engage it into the sewing position
- Rotate the top cover up and back to take it off
- Lift the thread holder and remove it as well
Step 2. Remove the bottom cover
- After taking off the top cover, remove the motor cover to get the bottom cover off
- Work off the screw at the bottom center of the motor cover plate
- Pull the motor cover down and towards you to remove it
- Remove all the remaining screws in the hole to take off the bottom cover
- Take off the bottom cover completely by removing its screw
- If removing the power input box, take out the screws inside the motor cover plate
- Do not remove the bottom screw of the power input box
- After removing the screw inside the motor cover plate, push the box into the base of your machine
How Do I Change The Lightbulb In My Pfaff Sewing Machine?

- Push the bulb cover as far as you can upward
- Turn the bulb counterclockwise, half a rotation to remove it
- Insert the new bulb into the lamp changer

- Push the bulb up as far as you can and rotate it clockwise, half a rotation, reversing the removal process earlier
- Take off the bulb changer while holding the bulb
How to remove the front cover of a Pfaff sewing machine
In some Pfaff sewing machines, you will remove the front cover to access and remove the light bulb.
- Remove the sewing machine’s top cover

How Do You Service A Pfaff Sewing Machine?

- Rethread the sewing machine and check if the needle is not broken or bent
- Inspect the bobbin and redo if needed
- Inspect the wiring for issues and have it repaired by a professional to avoid damaging it further
- Make sure you’ve cleaned and oiled your Pfaff sewing machine
How Do You Maintain A Pfaff Sewing Machine?
- Refer to the manual of the specific model you have and follow its cleaning indications
- Clean the sewing machine after every project or 8 hours of work
- Wipe the machine’s exterior with a soft and damp cloth, including the screen, if your unit has one

How do you lubricate a Pfaff sewing machine?
- Check if you must oil your model since some Pfaff sewing machines are self-lubricating
- Follow your manual for the oiling points and use a small amount of the proper sewing machine oil
- Make a few stitches to work in the oil and sew several scrap fabrics after 15 minutes to ensure that there are no more oil residues
And that’s it! To recap how to open a Pfaff sewing machine, you remove the screws on the covers and make sure to organize them inside ziplock bags for easier reassembly. You work the top, front, and bottom covers, ensuring that no pieces fall and get lost.
