Lubrication - Brother BE-438D Instruction Manual

3-13. Lubrication

Do not connect the power cord until lubrication has been completed, 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.
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 <NIPPON OIL CORPORATION Sewing Lube 10N; VG10> specified by Brother.
* If this type of lubricating oil is difficult to obtain, the recommended oil to use is <Exxon Mobil Essotex SM10; VG10>.
CAUTION
1. Fill the oil tank with oil.
Note:
Fill the machine with oil when the oil level is down to about
one-third full in the oil sight glass. If the oil drops below this
level, there is the danger that the machine may seize during
operation.
