Used diesel generators for sale (21)

1. Brand Reputation

Researching the manufacturer is critical. Quality brands tend to have better engineering, customer support, and warranties.

2. Age and Usage

Check the age of the diesel generator and how much it has been used. Generators, like other machinery, have a lifespan, and their condition can significantly impact their efficiency and reliability.

3. Maintenance History

A well-maintained generator is likely to be more reliable. Ask for records or proof of routine maintenance and servicing. Check for clean oil, smooth-running components, and absence of leaks.

4. Physical Inspection

Physically inspect the generator for any signs of wear or damage. Check for rust, dents, and other physical defects that might affect performance. Pay special attention to wirings, connections, and the control panel.

5. Output and Efficiency

Compare the output rated in kilowatts with your power needs. Ensure the generator can handle your maximum required load. Fuel efficiency is also crucial; efficient models will save on operating costs over time.

6. Noise Level

Assess the noise level, especially if using the generator in a noise-sensitive environment. Modern diesel generators often come with improved noise dampening technology.

7. Test Run

If possible, conduct a test run to observe any issues with starting, operation or unusual noises. This can reveal problems with the engine or other components not apparent through a visual inspection.

8. After-sales Services

Consider the availability of after-sales services and parts. Availability of a robust service network and spare parts can ease maintenance and repair works down the line.
