Page 3 Introduction The cause of most accidents is failure to adhere to basic safety rules and observe safety instructions. It is important to prevent potential causes of accidents from occurring. In order to do so, read this manual carefully , and be sure to understand all the safety instructions and correct inspection and servicing procedures that it provides before beginning repair or servicing work.
Page 4 • This service manual includes the structural and functional descriptions for the major areas of FD 574, along with the descriptions of procedures for disassembly and assembly , design standard and adjustment, maintenance and service requirements, and actions to be taken in the case of malfunctions.
Page 5 Safety Instructions Safety Instructions 1. Cautions regarding the installation location Caution Installation environment ● Avoid installing the machine in places exposed to direct sunlight. • Sunlight will cause the temperature in the machine’ s interior to rise, possibly leading to malfunction of the control system.
Page 6 Safety Instructions 2. Cautions for installation work WARNING ● The machine’ s power supply voltage and power consumption are given in the table below. The machine's power supply voltage is indicated on the identification plate on the machine; the machine must be connected to a power supply of the voltage indicated.
Page 7 Safety Instructions 3. Cautions for maintenance, inspection and servicing WARNING Always remove the power cord plug from the outlet before starting work. → Otherwise, your could get a shock or your hands/f ngers could be injured. • However, the plug must be left connected to the outlet when performing function checks (of individual motors, a given series of operations, or electrical circuits).
