  • Page 3: Safety Precaution For Repair

    The use of a substitute replacement component which does not have the same safety characteristics as the HITACHI recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards. Product safety is continuously under review and new instructions are issued from time to time.

  • Page 4: Lead-Free Solder

    Safety Precaution for Repair > Lead-Free Solder 1-3 Lead-Free Solder The printed circuit board that uses lead-free solder is adopted. To protect the global environment, use the recommended lead-free solder also during servicing. Read and observe the following before soldering: Caution ALWAYS wear protective goggles during soldering so that no solder smoke or scattered solder enters the eye.
