Key Maintenance Areas
Oil System Maintenance
Regularly check oil levels and quality. Use the manufacturer-recommended oil grade and change according to the maintenance schedule. The oil filter should be replaced with each oil change. Proper oil maintenance is critical for lubrication, cooling, and protecting internal engine components from wear and corrosion.
Cooling System Maintenance
Inspect coolant levels daily and maintain the proper coolant mixture ratio. Check for leaks in hoses, connections, and the radiator. Clean the radiator fins periodically to ensure optimal heat dissipation. An efficiently functioning cooling system prevents overheating and extends engine life.
Air Filtration System
Inspect the air filter regularly and clean or replace as needed. A clogged air filter restricts airflow, reducing engine performance and increasing fuel consumption. In dusty environments, more frequent inspection and cleaning may be necessary.
Fuel System Maintenance
Check fuel lines and connections for leaks. Replace fuel filters according to the maintenance schedule. Use clean, high-quality diesel fuel to prevent contamination. Water separators should be drained regularly to prevent water from entering the fuel system.
Electrical System Check
Inspect battery connections for corrosion and ensure proper charging. Check wiring harnesses for wear or damage. Verify alternator output meets specifications. A well-maintained electrical system ensures reliable starting and proper function of electronic components.
Exhaust System Inspection
Check for leaks, cracks, or damage in the exhaust manifold, pipes, and muffler. Ensure all mounting brackets are secure. A properly functioning exhaust system maintains back pressure at designed levels and helps the engine operate efficiently.
Important: Always follow the manufacturer's specific maintenance guidelines for your LOVOL 1104 engine model. Operating conditions such as extreme temperatures, dusty environments, or heavy loads may require more frequent maintenance intervals than those listed in the general schedule.
