Be sure to wear protective goggles and gloves when handling the lubricating oil, so that no oil gets into
your eyes or onto your skin, otherwise inflammation can result.
Furthermore, do not drink the oil under any circumstances, as it can cause vomiting and diarrhoea.
Keep the oil out of the reach of children.

The sewing machine should always be lubricated and
the oil supply replenished before it is used for the first
time, and also after long periods of non-use.
Use only the lubricating oil (Nisseki Mitsubishi Sewing
Lube 15N; VG15) specified by Brother.

between the reference lines on the oil gauge

erence line on the oil tank, no oil will be drawn into
the upper shaft, and the upper shaft will thus not be
lubricated sufficiently. Be sure to maintain the lubricat-
ing oil level at a level above the center reference line.
