5. Performing load tests
6. Scheduling regular run time
7. Storing properly when not in use

Implementing these practices can help ensure optimal performance and longevity.

1. Regular oil changes:
   Regular oil changes keep the engine running smoothly. Oil lubricates engine components and prevents wear and tear. According to the manufacturer’s guidelines, changing the oil every 50 to 100 hours of operation can prevent engine damage and maintain performance. Neglecting this task could lead to oil contamination, resulting in engine failure.

2. Cleaning or replacing air filters:
   Cleaning or replacing air filters ensures proper airflow to the engine. Clogged filters can reduce efficiency and power output. Regular inspection of filters every 25 to 50 hours is recommended. A clean filter promotes better combustion and improves fuel efficiency, while a dirty one can lead to engine overheating.

3. Checking and tightening connections:
   Checking and tightening electrical connections can prevent potential failures. Loose connections can cause intermittent power delivery and damage internal components. Routine inspections help maintain a stable operation and reduce the risk of unexpected breakdowns due to electrical issues.

4. Inspecting the fuel system:
   Inspecting the fuel system for leaks and blockages is crucial for optimal performance. Regularly examine the fuel lines and connections for deterioration. Fuel quality can affect engine operation. Consider using non-ethanol fuel to reduce the risk of corrosion and fuel degradation.

5. Performing load tests:
   Performing load tests verifies the generator’s capacity to handle power demands. Regular load testing ensures that the generator operates efficiently under stress. A load bank test is advisable at least once a year. This practice helps identify any performance issues before they become serious problems.

6. Scheduling regular run time:
   Scheduling regular run time helps keep the generator in good working condition. Running the generator regularly prevents fuel system problems and moisture accumulation. Aim for a monthly run time of at least 30 minutes to keep the engine and other components lubricated.

7. Storing properly when not in use:
   Proper storage safeguards the generator during periods of inactivity. Store the generator in a dry, sheltered location. Drain the fuel or add a fuel stabilizer to prevent degradation. Ensure the unit is covered to protect it from dust and environmental damage. This practice can extend the lifespan of the generator by preventing rust and corrosion.
