Additional Notes

  • The FG70-7 with Nissan TB42 engine and the FG70-8 with Nissan TB45E engine share an identical cooling system capacity of 17 liters, despite being distinct engine configurations across different series generations.
  • A 17-liter cooling system capacity is relatively large and reflects the demands of a high-displacement engine in a heavy-duty forklift application, where sustained thermal management is critical during extended operation.
  • Under normal use conditions, the cooling system on both the FG70-7 and FG70-8 requires a check interval of every 8 hours, which corresponds to a standard single-shift workday in forklift operations.
  • The coolant change interval for both configurations is set at 6 months or 1,200 hours under normal use conditions, with the dual-trigger format meaning whichever threshold is reached first would govern the service action.
  • A 1,200-hour change interval across a 6-month period implies an average operational rate of approximately 200 hours per month, which is consistent with continuous multi-shift industrial use.
