Keep Your Generator Clean And Inspect It Regularly For Damage Your RV generator is a hardworking device that lives in an unfriendly environment, typically in the underside of your RV. Dust and debris are a part of its daily life. Dust can clog the intake system and reduce its engine’s efficiency. Remember to replace air and oil filters regularly. Over time, vibration from rough roads can loosen generator fasteners, while debris thrown up from the road can occasionally damage fuel lines and exhaust systems. It makes good sense to regularly inspect all these items. Do not use a water hose or high pressure car wash type sprayers on the generator. Light air pressure and a damp cloth are preferred.
