Common Issues & Fixes

DEF System Warnings: Often due to contaminated DEF or faulty sensors—use fresh ISO-certified DEF and replace sensor if needed.

Hydrostatic Surge or Hesitation: Replace dirty charge filters and recalibrate system using onboard diagnostics.

Hydraulic Cylinder Drift: Rebuild tilt or lift cylinders with OEM seal kits; inspect rod surfaces for scoring.

Fuel Priming Problems: Caused by air leaks or low fuel pressure—inspect primer bulb and replace fuel filters regularly.

Cab Display Fault Codes: Check for corroded connectors near the ECM or behind the display—clean and reseat all plugs.

Track Tension Loss: Grease cylinder seals may be worn—install new seals and verify spring preload.
