3-2 Caution when Replacing Service Parts3-2-1 Electrical shockBe sure to disconnect the power cable and modular cable to prevent electrical shock.If working with power on is required, do not use grounding strap. Using such equipment maycreate conducting pathway, posing a risk of electrical shock.See the following for parts and components that may generate electrical shock:z Power supply unit primary (supplied with AC voltage)z Telephone line primary3-2-2 High temperatureIn order to prevent burns during disassembly, allow at least ten minutes, after the power has beenswitched off, for the high temperature components to cool down.General high temperature components are as follows.z Motorsz Power supply unitz Elements on driver ICs, etc., on PCBs (in particular, ICs with heatsinks)z FINE Cartridge aluminum plate3-2-3 FireIt is dangerous to throw lithium batteries and parts and components containing flammablesubstances, such as cartridges, etc., into fire. Such parts and components must be disposed of inaccordance with local laws and regulations.3-2-4 IgnitionWhen using solvents such as alcohol, etc., while conducting service, there is a danger of fireigniting from heat from internal circuitry and from sparks. Before using any such solvents, be sureto switch off the power and allow time for high temperature parts to cool down. Make sure thatthere is sufficient ventilation when working with solvents.3-2-5 Movable partsIn order to prevent accidents with movable parts, be sure to remove the power cable whenconducting service that requires disassembly. Also, take care that personal accessories and hair,etc., are not caught in any moving parts.
