Thank you very much for buying a BROTHER sewing machine. Before using your new machine, please read the safety instructions below and the explanations given in the instruction manual. With industrial sewing machines, it is normal to carry out work while positioned directly in front of moving parts such as the needle and thread take-up lever, and consequently there is always a danger of injury that can be caused by these parts.
SAFETY INSTRUCTIONS [1] Safety indications and their meanings This instruction manual and the indications and symbols that are used on the machine itself are provided in order to ensure safe operation of this machine and to prevent accidents and injury to yourself or other people. The meanings of these indications and symbols are given below. Indications DANGER The instructions which follow this term indicate situations where failure to follow the instructions will result in death or serious injury.
[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.
CAUTION Sewing This sewing machine should only be used by operators who have received the necessary training in safe use beforehand. If using a work table which has casters, the casters should be secured in such a way so that they cannot move. The sewing machine should not be used for any applications other than sewing. Attach all safety devices before using the sewing machine. If the machine is used without these devices attached, injury may result.
[3] Warning labels The following warning labels appear on the sewing machine. Please follow the instructions on the labels at all times when using the machine. If the labels have been removed or are difficult to read, please contact your nearest Brother dealer. 1 2 .
