8. MAINTENANCE AND INSPECTION

CAUTION

Turn off the power switch before starting any cleaning work, otherwise the machine may operate if the foot
switch is depressed 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.

8-2. Lubrication

Note

• Fill the machine with oil when the oil level is down to about one-third full in the oil sight glass.
• If oil is not added and the oil drops below this level, there is the danger that the machine may seize during

operation.

• Be sure to let the machine operate for a while after adding the oil.
• Use only specified Brother oil (Nisseki Mitsubishi Sewing Lube 10N; VG10) for the machine oil.
