Common Issues & Fixes

DEF System Derate or Faults: Often caused by degraded or old DEF—use fresh ISO-certified fluid, clean the DEF tank screen, and inspect injector nozzle.

Hydraulic Blade Drift or Lag: Worn lift or tilt cylinder seals—rebuild cylinders and inspect valve spool action.

Cab Display Glitches or Error Codes: CAN bus connection issue or voltage drop—reseat connectors and check grounds near display.

Overheating in Dusty Conditions: Clogged radiator or fan failure—clean cooling module thoroughly and inspect belt and fan clutch.

Transmission Travel Lag: Faulty swash plate calibration or low charge pressure—perform system diagnostic and recalibrate via onboard display.

Brake System Drag or Noise: Internal hydraulic brake wear—flush fluid and inspect the wet disc pack for signs of scoring or wear.
