| A prerequisite for deciding on whether to repair any sewing machine is to first establish that it is in fact, actually broken! |
|
| To do this you will need to understand how the machine should normally perform when in use and its limitations when set up and operated correctly. |
|
| In the first instance the manufacturer’s user manual should be checked for operating instructions, specifications and indications of what the machine is capable of achieving. |
|
| If the machine performs as intended by the manufacturer then it does not need to be repaired. |
|
| If it doesn’t perform as intended then: |
|
| * it’s very possible that the machine has not been set up properly and/or is being operated incorrectly |
| * unsuitable threads or materials have been used |
| * incorrect needles, presser feet, bobbins, bobbin case or hook are being used |
| * the machine needs routine care/maintenance (cleaning, lubrication etc.) |
| If these factors can be ruled out then the machine is probably malfunctioning and may need servicing, adjustment or repair. |
