  2. Power system:
    Check antifreeze freezing point daily (must be 10°C lower than ambient temperature).
  3. Drilling tool system:
    Apply antifreeze lubricating grease (drop point ≥150°C) after use.
  4. Electrical system:
    Test cable insulation resistance weekly (must be >10MΩ).
  5. Cooling system:
    Let the engine idle for 10 minutes before shutdown to prevent thermal stress cracking.
