Common Issues & Fixes

• Hydraulic Hose Wear: Inspect daily, especially near quick-couplers; replace worn hoses early

• Track Tension Drift: Use grease-adjust fitting to keep proper tension, prevent track derailment

• Cooling Pack Blockage: Dust buildup can reduce airflow – daily cleaning prolongs cooler life

• Hydraulic Response Lag: Often due to clogged filters or low fluid – inspect and service promptly

• Control Drift or Lag: May require joystick recalibration or lubrication at pivot joints
