Sewing machine maintenance: a simple guide

1) Cleaning (which solves 80% of the problems)

• Turn off the machine and unplug it.

• Remove the bobbin and clean any lint/fluff from the shuttle/feed teeth area.

• Use a brush (don't "push" lint inside).
  Manufacturer support guides reinforce steps such as safely disconnecting and cleaning the coil area.

2) Needle change (more important than it seems)

Exchange if:

• the needle hit the pin/zip

• the stitches are starting to fail

• There are tugs on the fabric.

• the line breaks down for no reason.

3) Thread and bobbin (compatibility)

• Avoid using very old and fuzzy yarn (it increases lint).

• Use the correct coils for the model.

4) Tension and unsightly points: quick checklist

If the stitch comes loose underneath:

• confirms superior alignment

• Check if the coil is positioned in the correct direction.

• Clean the coil area.

If the line breaks:

• damaged needle

• very high voltage

• poor quality line

5) Storage

• cover/bag

• dry place

• away from dust
