CAUTION

Turn off the power switch before starting lubricating, otherwise the machine may operate if the start switch is pressed by mistake, which could result in injury.

Be sure to wear protective goggles and gloves when handling the lubricating oil and grease, so that they do not get into your eyes or onto your skin, otherwise inflammation can result.

Furthermore, do not drink the oil or eat the grease under any circumstances, as they can cause vomiting and diarrhoea.

Keep the oil out of the reach of children.

Use only specified Brother oil (Nisseki Mitsubishi Sewing Lube 10 N; VG10) for the machine oil.
