[2] Notes on safety  
DANGER  
Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall outlet  
before opening the cover of the control box. Touching areas where high voltages are present can result in severe  
injury.  
WARNING  
Do not allow any liquids to get onto this sewing machine, otherwise fire, electric shocks or operating problems may  
occur.  
If any liquid gets inside the sewing machine (machine head or control box), immediately turn off the power and  
disconnect the power plug from the electrical outlet, and then contact the place of purchase or a qualified  
technician.  
CAUTION  
Environmental requirements  
Use the sewing machine in an area which is free from  
sources of strong electrical noise such as electrical  
line noise or static electric noise.  
The pneumatic delivery capability should be greater  
than the requirements for the sewing machine's total  
air consumption.  
Sources of strong electrical noise may cause  
problems with correct operation.  
Insufficient pneumatic delivery capability may cause  
problems with correct operation.  
Any fluctuations in the power supply voltage should  
be within ±10% of the rated voltage for the machine.  
Voltage fluctuations which are greater than this may  
cause problems with correct operation.  
The ambient temperature should be within the range  
of 5°C to 35°C during use.  
Temperatures which are lower or higher than this  
may cause problems with correct operation.  
The power supply capacity should be greater than the  
requirements for the sewing machine's power  
consumption.  
Insufficient power supply capacity may cause  
problems with correct operation.  
The relative humidity should be within the range of  
45% to 85% during use, and no dew formation should  
occur in any devices.  
Excessively dry or humid environments and dew  
formation may cause problems with correct operation.  
In the event of an electrical storm, turn off the power  
and disconnect the power cord from the wall outlet.  
Lightning may cause problems with correct operation.  
Installation  
Machine installation should only be carried out by a  
qualified technician.  
All cords should be secured at least 25 mm away  
from any moving parts. Furthermore, do not  
excessively bend the cords or secure them too firmly  
with staples, otherwise there is the danger that fire or  
electric shocks could occur.  
Contact your Brother dealer or a qualified electrician  
for any electrical work that may need to be done.  
The sewing machine weighs approximately 88 kg.

3-16. Lubrication  
CAUTION  
Do not connect the power cord until lubrication is complete.  
If the foot switch is depressed by mistake, the sewing machine might start operating and injury could result.  
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. If the oil and grease get into your eyes or onto your skin, inflammation can result.  
Furthermore, do not drink or eat the lubricating oil or grease. They may cause diarrhea or vomiting.  
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 <JX Nippon Oil & Energy 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>.  
2368B  
5221Q

Use a CF card with a memory capacity of 32, 64, 128, 256, 512 MB, 1GB or 2GB.  
(CF cards with a capacity of more than 2GB are not supported.)  
Do not disassemble or modify the CF card.  
Do not bend, drop or scratch CF cards or place heavy objects on top of them.  
Avoid contact with liquids such as water, oil, solvents or drinks.  
Use and store CF cards in locations that are free from strong static electricity and electrical interference.  
Do not use or store CF cards in places where they may be subject to vibrations or shocks, direct sunlight, high  
temperature or humidity or strong magnetic fields from equipment such as speakers, or places which are dusty from thread  
scraps, etc.  
Do not subject CF cards to shocks or impacts or remove them from the sewing machine while data is being loaded or  
written.  
The data on the CF cards may become lost or corrupted due to some malfunction or accident. It is recommended that you  
make a backup of important data.  
CF cards should only be removed after the power for the sewing machine has been turned off.  
CF cards are already formatted when they are purchased, and so you should not reformat them.  
The recommended CF cards are commercially-available ones from SanDisk or HAGIWARA SYS-COM. CF cards from  
other manufacturers can be used, but different formatting methods may mean that loading from or writing to such cards  
may not be possible.  
For more information, refer to the documentation provided with the CF card.
