The radiator core of the hydraulic excavator needs to be guaranteed the area of certain air circulation to better protect the heat dissipation function of the radiator. The possibility of a blockage in the radiator needs to be cleaned up in time.
The vent hole of the engine hatch should be guaranteed not to be blocked in order to efficiently exhaust the heat. Make sure that there is enough supply air rate near the radiator. The position and distance of fan and guide hood and its engine need reasonable regulation, which should carried out according to the actual situation.
Any engineering machinery or accessories require professional maintenance. Check whether the radiator and other cooling parts can work normally in hot weather and ensure the safe construction.（message from Leo）
