Is there a temperature gauge for the radiator and hydraulic fluid to let you know when you need to clean the screens? You never mentioned how you know it is overheating. Is it possible to ruin the engine if you let it get too hot, or did they engineer in some sort of safety shut off?
@johnevans6053 There is a temperature gauge you can monitor along with warning lights and a audible alarm as well for both engine temperature, And hydraulic temperature. I have never had a problem with either overheating. It is always good to keep the cooling systems clean.
