تعمیر و نگهداری
Regular maintenance ensures your Brother SH7700 sewing machine remains in excellent working condition. Always disconnect the machine from the power supply before performing any maintenance.
- Cleaning the Bobbin Area: Periodically remove the needle plate and bobbin case. Use a small brush (often included with the machine) to remove lint and dust accumulation from the bobbin area and feed dogs.
- Cleaning the Tension Discs: Floss a piece of thread or a thin cloth between the upper thread tension discs to remove any trapped lint that might affect thread tension.
- تعویض سوزن: Replace the needle regularly, especially after 8-10 hours of sewing or if it becomes bent or dull. A dull needle can cause skipped stitches and fabric damage.
- نظافت عمومی: Wipe down the exterior of the machine with a soft, dry cloth to remove dust. Avoid using harsh chemicals or abrasive cleaners.
- روغن کاری: Consult your machine's specific instructions regarding oiling. Many modern sewing machines, including computerized models, are self-lubricating and do not require user oiling. Incorrect oiling can damage the machine.
