i EF4-N11, N21, MA4-N31 (English) 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.
ii 2. Notes on safety 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 electri- cal consumption.
iii CAUTION Turn off the power switch before starting any cleaning work, otherwise the machine may oper- ate if the treadle is depressed by mistake, which could result in injury. * When using a clutch motor, the motor will keep turning even after the power is switched off as a result of the motor’s inertia.
iv EF4-N11, N21, MA4-N31 (German) Vielen Dank, daß Sie sich für eine BROTHER-Nähmaschine entschieden haben. Lesen Sie bitte vor der Inbetriebnahme der neuen Nähmaschine die nachstehenden Sicherheitshinweise und die in der Bedienungsanleitung angegebenen Erklärungen durch.
v EF4-N11, N21, MA4-N31 (German) Schwankungen der Netzspannung dürfen nicht mehr als ± 10% der Maschinen-Nennspannung be- tragen. Größere Schwankungen können Betriebsstörungen verursachen. Die Kapazität der Stromversorgung muß für die ge- samte Leistungsaufnahme der Maschine ausrei- chend sein.
vi EF4-N11, N21, MA4-N31 (German) ACHTUNG Schalten Sie zum Reinigen immer den Netzschalter aus. Es besteht Verletzungsgefahr, wenn die Näh- maschine durch unbeabsichtigtes Betätigen des Pedals in Gang gesetzt wird. * Bei Verwendung eines Kupplungsmotors dreht sich der Motor wegen der Trägheit auch nach dem Aus-schalten weiter.
