- Heating and Air Conditioning: HVAC diagnostics, operational checks, refrigerant-related testing, and component troubleshooting.
Practical Problems This Manual Helps Investigate
When a 670G or 672G develops a warning message, abnormal drivetrain behavior, hydraulic performance issue, 6WD fault, or electrical problem, replacing parts based only on symptoms can become expensive. The diagnostic procedures in this manual help you work through the system logically, identify the affected circuit or component, perform the required test, and verify the result.
For example, the electrical section can help when a controller-related fault appears, while the hydraulic and powertrain sections provide system-specific testing when machine performance changes under load. HVAC testing is also included for problems involving cooling, heating, blower operation, or refrigerant-system performance.
