ENF002-2Power supplyThe tool should be connected only to a power supply ofthe same voltage as indicated on the nameplate, and canonly be operated on single-phase AC supply. They aredouble-insulated and can, therefore, also be used fromsockets without earth wire. ENF100-1For public low-voltage distribution systems ofbetween 220 V and 250 V.Switching operations of electric apparatus cause voltagefluctuations. The operation of this device underunfavorable mains conditions can have adverse effectsto the operation of other equipment. With a mainsimpedance equal or less than 0.31 Ohms it can bepresumed that there will be no negative effects. Themains socket used for this device must be protected witha fuse or protective circuit breaker having slow trippingcharacteristics.ENG905-1NoiseThe typical A-weighted noise level determined accordingto EN60745:Model HM1801Sound pressure level (LpA) : 84 dB (A)Sound power level (LWA) : 104 dB (A)Uncertainty (K) : 2.30 dB (A)Model HM1810Sound pressure level (LpA) : 84 dB (A)Sound power level (LWA) : 104 dB (A)Uncertainty (K) : 2.52 dB (A)Wear ear protectionENG900-1VibrationThe vibration total value (tri-axial vector sum) determinedaccording to EN60745:Model HM1801Work mode : chiselingVibration emission (ah,CHeq ) : 14.0 m/s2Uncertainty (K) : 1.5 m/s 2Model HM1810Work mode : chiselingVibration emission (ah,CHeq ) : 9.0 m/s2Uncertainty (K) : 1.5 m/s 2
