HE-800A ELECTRONIC LOCKSTITCH BUTTON HOLER
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.
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 electrical line noise or static electric noise.
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 2a NOTE: Either the 2a or the 2b label is displayed on the sewing machine. *Safety devices Eye guard, Finger guard, Thread take-up cover, Belt cover, Belt cover plate, etc. 2b iv 3 Be sure to connect the ground.
