The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
HX99B-2, (S/N 000312->) (2007-2015)
  • Use: Normal
  • Capacity 3,5 liter
  • Check 8 hours
  • Change 24 months/ 2000 hours

Additional Notes

  • The cooling system capacity for the Hitachi HX99B-2 (S/N 000312 and above) is 3.5 liters, which represents the total system fill volume including the radiator, hoses, and reservoir.
  • A coolant level check interval of every 8 hours places the HX99B-2 in a category of machines requiring frequent fluid monitoring, consistent with the demands of aerial work platform operation cycles.
  • The change interval is set at 24 months or 2,000 hours, whichever comes first, under normal use conditions, meaning the machine is not subjected to the more demanding duty cycles that would otherwise shorten the service period.
  • The dual-trigger change interval of 24 months or 2,000 hours reflects that calendar time and operational hours are treated as independent thresholds, so a unit accumulating hours slowly would still require a coolant change at the two-year mark.
