Additional Notes

  • All five Komatsu WH-series telehandler models covered — WH609, WH613, WH713, WH714, and WH716 — share an identical brake fluid capacity of 0.65 liter for the hydraulic brake system.
  • A 0.65 liter capacity is a relatively small service fill volume, consistent with a dedicated hydraulic brake circuit rather than a shared or integrated hydraulic reservoir.
  • The check interval across all listed models is every 8 hours of operation under normal use conditions, which corresponds to approximately one standard working shift.
  • The change interval is specified as 24 months or 2,000 hours, whichever comes first, under normal use conditions. The dual-trigger format means time elapsed and operational hours are both active thresholds.
  • A 2,000-hour change interval for brake fluid reflects the moisture-absorption characteristics of glycol-based brake fluids, which degrade over time regardless of usage intensity.
  • The WH714 covers the 2004-2006 model years, a narrower range than the 2004-2009 span shared by the WH609, WH613, WH713, and WH716.
  • Despite the difference in model year coverage, the WH714 carries the same 0.65 liter capacity and the same 8-hour check and 24-month/2,000-hour change intervals as the other four models.
