Lubrication - Brother S-7100A Basic Operation Manual

1. INSTALLATION

1-3. Lubrication

Do not connect the power cord until lubrication has been completed, otherwise the machine may operate if the
treadle is depressed by mistake, which could result in injury.
Be sure to wear protective goggles and gloves when handling the lubricating oil, so that it does not get into your
eyes or onto your skin.
If care is not taken, inflammation can result. Furthermore, do not drink the lubricating oil. Diarrhea or vomiting may
result.
Keep the oil out of the reach of children.
When cutting the nozzle of the oil tank, hold the base of the nozzle securely.
If you hold the end of the nozzle, injury from the scissors may result.
