Your Quick Generator Maintenance Checklist


A gas or diesel generator is not the kind of thing you can set and forget about. By prioritizing which components to inspect and when to examine them, a generator maintenance checklist enables you to keep the generator in good working order when you need it most.

Generators are prone to fuel issues without routine maintenance, which can eventually lead to malfunctions and possibly ruin a generator. A gas or diesel generator should be periodically operated as part of maintenance, just as your automobile should be driven at least once every week, even if it’s only a short distance. Improper maintenance of generators in residential buildings can also lead you to fail recertification.

Do a safety inspection on the electrolyte levels and battery cables every month. Cleaning corrosion or filth with a toothbrush and baking soda requires removing the plastic covers from the cell ports.

Look for any indications of leaks in the oil or coolant lines, and check the levels of the engine’s coolant and oil. Check the coolant’s composition as well; it should be nearly equal parts filtered water and antifreeze. The antifreeze level can be as high as 60% if you reside somewhere where there is a possibility of freezing.

To make sure everything is functioning properly, perform a load test once a month for at least an hour using a load bank. At this time, you should also do an electrical conductivity test or an electrolyte-specific gravity test.

We hope this checklist will help you keep your generators in running condition for a long time. For helpful advice, contact ML Engineering and Inspection Services, your trusted 40 year inspection experts.
