Common Issues & Fixes

Hydraulic Lag or Drifting: Caused by worn valve spool seals or air in lines—bleed system and reseal valves if needed.

Boom or Arm Creep: Internal cylinder bypass—test pressure loss and repack affected cylinder.

Fuel Restriction Warning: Often due to clogged primary fuel filter—replace both filters and drain water separator.

Display or Electrical Glitches: Inspect wiring under cab and ground connections—corrosion-prone in wet environments.

Swing Motor Hesitation: Likely caused by case drain blockage or motor seal leak—test pressure and rebuild if necessary.

Track Noise or Jerky Travel: Caused by worn sprockets or improper tension—adjust or replace undercarriage components.
