Maintenance Procedures
Weekly Maintenance
Routine weekly maintenance is essential for ensuring the generator operates efficiently. Key tasks include:
- Check Engine Oil Level: Ensure the oil level is between the upper and lower dipstick marks.
- Inspect Diesel Fuel: Check for leaks and ensure the fuel is settled for 24 hours before use.
- Coolant Level Check: Maintain the coolant level about 5 cm below the cap.
- Air Filter Inspection: Replace if the indicator shows a red mark.
- Battery Voltage Check: Ensure the battery is charging correctly.
Monthly Maintenance
Monthly maintenance involves more comprehensive checks:
- Load Testing: Run the generator with a load for at least 30 minutes.
- Environmental Inspection: Ensure the engine room is clean and well-ventilated.
- Belt Condition Check: Inspect and adjust the fan belt as necessary.
- Wiring Inspection: Ensure all connections are secure and free from corrosion.
Annual Maintenance
Annual maintenance should be performed by experienced technicians and includes:
- Fuel Filter Replacement: Change the fuel filter and drain the fuel tank.
- Valve Clearance Check: Adjust if necessary to maintain engine performance.
- Load Testing: Conduct a load test to ensure the generator can handle operational demands.
- Lubrication System Check: Add lubricating oil to components as needed.
