Service intervals depend on running hours rather than calendar time, with oil, filters, and coolant typically checked every 250 to 500 hours depending on the manufacturer, but UAE dust conditions often require more frequent air filter inspection. Daily pre-start checks of fluid levels, leaks, and battery condition catch developing issues before they cause downtime. Load bank testing periodically confirms the generator can still deliver rated output under load. Sparkline Group offers scheduled maintenance contracts tailored to actual running hours on UAE sites.
