2. Engine Overheating
   Overheating can result from a variety of issues, including a clogged radiator, low coolant levels, or a malfunctioning thermostat. To resolve this:
   • Clean the radiator to ensure it’s free of debris.
     
   • Check coolant levels and top them up if necessary.
     
   • Inspect the thermostat and replace it if it’s faulty.
     
3. Unstable or Uneven Tracks
   Uneven or unstable tracks can affect the machine’s stability, especially when operating on rough terrain. This can be caused by uneven wear, improperly tensioned tracks, or damaged rollers. To troubleshoot:
   • Inspect the tracks for wear and replace them if necessary.
     
   • Ensure the track tension is properly adjusted.
     
   • Inspect the rollers and undercarriage for damage.
     
4. Electrical System Failures
   Electrical problems, such as a malfunctioning monitor panel or issues with lighting, can also arise. Check for:
   • Blown fuses and replace them.
     
   • Loose wiring connections.
     
   • Battery voltage and charging system.
     

Regular Maintenance Tips
