Additional Notes

  • The Komatsu Forklift Tusk AX/BX20 series hydraulic clutch system holds 0,1 liter of clutch fluid across both the 500CG-14 with Nissan K21 engine and the 600PGSH-14 with Nissan K25 engine. A capacity this small is consistent with a sealed hydraulic clutch reservoir rather than a large open system, meaning even minor fluid loss can affect clutch performance noticeably.
  • The 8-hour check interval on both configurations corresponds to a standard operator shift cycle in forklift operations, placing clutch fluid level verification as a daily pre-shift or post-shift task under normal use conditions.
  • The change interval of 6 months or 1200 hours, whichever comes first, applies to both the K21 and K25 engine variants under normal use. The dual-trigger format means time elapsed and operational hours are each independent thresholds, so a unit used infrequently would still require a fluid change at the 6-month mark.
  • No variation in clutch fluid capacity or service intervals exists between the 500CG-14 and 600PGSH-14 configurations, despite the two models using different Nissan engine families, K21 and K25 respectively.
