Such a practice may result in breakdown of this equipment or peripherals, injury or even death. Hitachi will not be responsible for any accident or failure resulting from such mishandling.
  • Page 6 During work For each procedure, follow the given sequence of steps. Use the special tools and instruments, specified for the work in the manual or commercially available tools and instruments which fit the purpose. Use measurement instruments and powered tools which are properly calibrated or periodically inspected.
  • Page 7 Prevention of electric shocks Before starting work, make sure that, unless otherwise specifically instructed, there is no potential electric hazard in the maintenance area such as insufficient grounding or a wet floor. Before starting work, note where the emergency power-off switches are located and make sure you know how to operate them.
  • Page 8 Procedures in an emergency For electric shock Do not panic. Do not become another victim through contact with the injured person. First, shut off the electric current passing through the victim. Use the emergency power-off switch, if there is one, or, otherwise, a normal power- off switch.
