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 face plate of the control box. Touching areas where high voltages are present can result in severe injury.
CAUTION
Environmental requirements
Use the sewing machine in an area which is free from sources of strong electrical noise such as
Sources of strong electrical noise 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 power supply capacity should be greater than the requirements for the sewing machine's electrical consumption.
Insufficient power supply capacity 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 relative humidity should be within the range of 45% to 85% during use, and no dew forma- tion should occur in any devices.
Excessively dry or humid environments and dew formation may cause problems with cor- rect operation.
Avoid exposure to direct sunlight during use. Exposure to direct sunlight may cause prob- lems 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.
Contact your Brother dealer or a qualified elec- trician for any electrical work that may need to be done.
The sewing machine weighs more than 720 kg. The installation should be carried out by a lift or a crane.
Do not connect the power cord until installa- tion is complete, otherwise the machine may operate if the start switch is pressed by mis- take, which could result in injury.
Be sure to connect the ground. If the ground connection is not secure, you run a high risk of receiving a serious electric shock, and problems with correct operation may also occur.
When securing the cords, do not bend the cords excessively or fasten them too hard with staples, otherwise there is the danger that fire or electric shocks could occur.
Be sure to wear protective goggles and gloves when handling the lubricating oil or grease, so that no oil or grease gets into your eyes or onto your skin, otherwise inflammation can result.
Furthermore, do not drink the oil or grease un- der any circumstances, as they can cause vom- iting and diarrhoea.
Keep the oil out of the reach of children.
Avoid setting up the sewing machine near sources of strong electrical noise such as high- frequency welding equipment.
If this precaution is not taken, incorrect machine operation may result.
Secure the machine with the adjustment bolts on the sound floor so that it will not move.
