Chapter 9 Maintenance
Turn off the power switch before starting maintenance.
Failure to do so may start the machine unintentionally through an accidental activation of the START
switch, resulting in bodily injuries.
Be sure to wear protective goggles and gloves when handling the lubricating oil or grease, so that no oil
or grease gets into your eyes or onto your skin, otherwise inflammation can result.
Furthermore, do not drink the oil or grease under any circumstances, as they can cause vomiting and
diarrhoea.
Keep the oil out of the reach of children.
• Keep the machine clean at all times to prevent machine trouble.
• Remove dirt with a soft, dry cloth. If necessary, clean with the detergent-soaked cloth, then wipe
off the detergent with a cloth dampened with (hot) water.
• Never use benzene or thinner for cleaning the machine.

1. Cleaning

1-1 Cleaning and Lubrication of Rotary Hook

• Clean rotary hooks daily using the brush provided at the time of lubrication. If a rotary hook is too
dirty, cleaning with a compressor (compressed air) is recommended.
• In case of thread breakage errors or noises of the rotary hook, one drop lubricate the race of the
rotary hook in every 3 or 4 hours operation.
• Use the dropper provided to supply oil. Use Brother's specified oil (Nippon Oil, Embroidery Lube
10N; VG10).
* If this type of lubricating oil is difficult to obtain, the recommended oil to use is <Exxon Mobil
Essotex SM10; VG10>.
• Supply a proper amount of oil. Any excess may stain fabrics, etc.
