Komatsu Forklift trucks, diesel - DX20 series

Brake fluid capacity & service interval

Komatsu Forklift trucks, diesel - DX20 series utilize brake fluid with a capacity of 0,05 liter. Service intervals include checks every 8 hours and changes every 6 months or 1200 hours. The data covers 3 configurations.

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

Additional Notes

  • The hydraulic brake system capacity across the FD70-7, FD70T-8, and FD80T-8 configurations is 0.05 liter, a notably small volume that reflects a reservoir-level service fill rather than a full system overhaul quantity.
  • The Komatsu Forklift DX20 series FD70-7 with the 6D102E engine, starting from serial number 40001, carries the same 0.05-liter brake fluid capacity as the turbocharged and supercharged variants in the FD70T-8 and FD80T-8.
  • A check interval of every 8 hours applies to the hydraulic brake system on all three configurations, which in forklift operation typically corresponds to a single work shift, placing brake fluid monitoring on a daily service cycle.
  • The change interval is specified as 6 months or 1200 hours, whichever comes first, under normal use conditions across the FD70-7, FD70T-8, and FD80T-8 configurations.
  • The FD70T-8 is paired with the turbocharged S6D102E engine from serial number 46001 onward, while the FD80T-8 uses the supercharged SA6D102E from the same serial number range, yet both share identical brake fluid service specifications.
  • The dual-trigger change interval of 6 months or 1200 hours means that in lower-utilization environments, the calendar-based threshold of 6 months would govern the service schedule before the hourly limit is reached.
