Common Issues and Troubleshooting:

1. Engine Shutdown Shortly After Starting:
   • Possible Causes: Fuel solenoid failure or clogged fuel filter.
     
   • Solution: Inspect the fuel solenoid valve for proper operation and electrical continuity. Clean or replace the fuel filter to ensure adequate fuel flow. In cold weather, warming the fuel tank can help prevent gelled diesel.
     
2. Vapor Lock Leading to Starting Issues:
   • Possible Causes: Overheated fuel causing vapor formation, blocking fuel flow.
     
   • Solution: Check the injector pump for leaks or air ingress. Inspect fuel lines for heat exposure and replace any brittle hoses. Bleed the fuel system to remove trapped air. Using heat shields or rerouting fuel lines away from hot engine parts can prevent vapor lock.
     
3. Electrical Warning Lights and Shutdown:
   • Possible Causes: Electrical issues such as faulty sensors or wiring.
     
   • Solution: Perform a diagnostic check to identify any fault codes. Inspect wiring harnesses for loose connections or damage. Test sensors and replace if necessary. Regular maintenance of the electrical system can prevent unexpected shutdowns.
     

Maintenance Tips:

• Every 8-10 Hours:
  • Check engine oil level and add oil as needed.
    
  • Inspect the engine air filter and air system; service only when required.
    
  • Check the engine cooling system for debris and clean as necessary.
    
• Every 250 Hours:
  • Grease steering lever pivots.
    
  • Inspect the drive belt for wear or damage; adjust as needed.
    
  • Check the fan drive gearbox for proper lubrication and add gear lube if necessary.
