generator maintenance

A break-in service is the essential first maintenance for your new generator after its initial run time. It includes changing the oil and filter, adjusting the valves, inspecting key components, and removing any metal particles that accumulate as engine parts settle.

This service must be performed at 25 hours of run time, immediately following the break-in period. It’s the very first scheduled maintenance to ensure your generator starts strong. Our Smart Start Service accelerates this timeline to ensure your generator is ready to run for up to 200 hours. 

The break-in service is critical because during the first 25 hours, the engine’s moving parts wear in and release tiny metal debris into the oil. If this isn’t removed promptly:

• It can cause premature engine wear and damage
• Reduce your generator’s performance and reliability
• Shorten its overall lifespan
• Void your manufacturer’s warranty if missed
   

Completing the break-in service on time protects your investment and sets your generator up for long-term, dependable operation—ensuring you’re ready when the power goes out.
