14. TROUBLESHOOTING
•
If the performance of the machine becomes unsatisfactory, first check to confirm that the needle has been correctly
installed and that threading has been done correctly.
•
Please check the following points before calling for repairs or service.
•
If the following suggestions do not solve the problem, turn off the machine power supply and contact your nearest
Brother service center.
•
Turn off the power switch and disconnect the power cord before carrying out troubleshooting, otherwise the
machine will operate if the treadle is pressed by mistake, which could result in injury.
* When using a clutch motor, the motor will keep turning even after the power is switched off as a result of
the motor's inertia. Wait until the motor stops fully before starting work.
