Do not tamper with the power supply cable plug. If the power supply cable plug cannot be connected to the –

outlet, have new grounded outlet installed by a qualied technician, according to the law in force. Before connecting the power supply cable to the electrical mains, check that frequency and voltage, shown –

on the machine serial number plate, match the electrical mains voltage. Do not unplug the machine by pulling the supply cable. To unplug, grasp the plug, not the cable. – Do not handle the plug or the machine with wet hands. – Turn off all controls before unplugging. –

Regularly check the power supply cable for damages, cuts, cracks and wear. If necessary, replace it. – If the power supply cable is damaged, contact the Nilsk Service Center for replacement. –

Do not pull or carry the machine by the power supply cable and never use the power supply cable as a – handle. Do not close a door on the power supply cable, or pull the power supply cable around sharp edges or corners. Do not run the machine on the power supply cable. The brushes must not come into contact with the power supply cable. – Keep the power supply cable away from heated surfaces. – To reduce the risk of re, electric shock, or injury, do not leave the machine unattended when it is plugged – in. Disconnect the machine from the electrical mains when not in use and before performing maintenance procedures. If the machine: –

• does not work properly
