Changing the engine oil and oil filter after every 50 hours of use or every six months, whichever comes first, is recommended. Used engine oil contains impurities that can damage the engine if left unused. Replacing it with fresh oil helps remove these impurities and lubricates the internal parts. Similarly, the oil filter collects solid particles from the oil. Changing it ensures a clean lubrication supply to the engine.

Inspecting and Cleaning the Air Filter

The air filter should be inspected every 50 hours or six months and replaced if needed. It filters dust and debris from the intake air to keep the engine running smoothly. Over time, the filter becomes clogged, restricting airflow.

Cleaning or replacing it ensures the engine receives ample clean air for proper Battery Maintenance. Batteries require routine maintenance, like cleaning terminals and checking electrolyte levels. They should be replaced every 2-3 years. A poorly maintained or weak battery can cause starting issues.

Spark Plug Replacement

Spark plugs must be replaced annually or every 100 hours of operation. Old or faulty spark plugs cannot create hot sparks needed for ignition. Replacing them with new plugs maintains proper combustion inside the engine.

Regular maintenance is the key to deriving optimum performance from your generator. Following these routine tasks ensures it is in good working condition to deliver reliable backup power whenever needed.
