1. First, drain the radiator (to reduce the heat generated by the operation of the equipment) and the antifreeze coolant in the engine block. Then close the drain plug and add tap water and detergent to the radiator.

2. Start the engine and run it at a speed slightly higher than the low idle speed. Continue to run the engine for about 10 minutes when the thermometer means the part used to indicate the corresponding time is in the green zone. Guardrail piling machine is a kind of steel pipe piling equipment for highway guardrail. Diesel powered, fully hydraulic mechanical transmission. It has the characteristics of light piling, high piling accuracy, good durability, energy saving and environmental protection, and is especially suitable for field engineering construction such as highway guardrail installation, maintenance, and emergency repair.

3. Shut off the engine and open the drain plug, flush the cooling system with tap water until the drained water is clean. After continuous research and development and updating, this new type of full hydraulic piling equipment, which is superior to energy saving and environmental protection, fully reflects its high quality, high efficiency, high energy saving and long life in the installation of highway guardrails in various complex formations. Our company's quality inspection department has a set of strict testing technology and testing requirements, which provides a fluid quality protection barrier for the product, which has become an essential type of equipment in the installation of highway guardrails in my country.
