Komatsu Forklift trucks, diesel - BX20 series, -14

Brake fluid capacity & service interval

Komatsu Forklift trucks, diesel - BX20 series, -14 use Brake fluid with a capacity of 0,5 liter. Service intervals include checking every 8 hours and changing every 6 months or 1200 hours. The data covers 6 configurations.

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

Additional Notes

  • All six configurations in the Komatsu BX20 series (-14) share an identical brake fluid capacity of 0.5 liter, which is consistent with a compact hydraulic brake circuit typical of counterbalance forklift trucks in the 2–3 tonne class.
  • The 0.5 liter figure applies to the hydraulic brake system specifically, distinguishing it from the main hydraulic system reservoir found elsewhere on the same machines.
  • A check interval of every 8 operating hours places brake fluid inspection on a daily service schedule, reflecting the safety-critical nature of the braking circuit in industrial lift truck operation.
  • The change interval is defined by whichever limit arrives first: 6 months or 1,200 operating hours. The dual-trigger format accounts for fluid degradation through moisture absorption over time, which occurs regardless of machine usage.
  • The 6-month calendar limit is particularly relevant in lower-utilization environments where 1,200 hours may not be reached within that period, since brake fluid hygroscopicity causes performance decline independently of operational cycles.
  • The FD20T-14, FD25T-14, and FD30T-14 variants differ in rated load capacity (2,000 kg, 2,500 kg, and 3,000 kg respectively as indicated by the model numbering convention), yet all share the same 0.5 liter brake fluid specification, indicating a common brake system architecture across the series.
  • The "US" suffix variants (FD20TUS-14, FD25TUS-14, FD30TUS-14) carry identical brake fluid capacities and service intervals to their non-US counterparts, suggesting the hydraulic brake circuit design is unchanged between the two configuration types.
  • All six rows are designated under normal use conditions, meaning the 8-hour check and 6-month/1,200-hour change intervals apply to standard operating environments without adjustment for more demanding duty cycles.
