3. INSTALLATION
3-4. Connecting the cords
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.
Contact your Brother dealer or a qualified electrician for any electrical work that may need to be done.
Do not connect the power cord until all cords have been connected.
The machine may operate if the treadle is depressed by mistake, 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.
