Key considerations for the first start-up of a highway pile driver include:

1. Do not use antifreeze or boiling water to start. Starting the engine with these can cause important parts like the cylinder liner and cylinder head to crack and deform due to sudden cooling. Adding boiling water to a cold cylinder can also cause the cylinder head and body to crack.

2. Do not neglect oil changes; ensure timely refueling. Guardrail pile drivers, designed for installing, repairing, and emergency fixing of steel pipe pile highway barriers, are powered by diesel engines and hydraulic machinery. They are known for their light driving force, high piling accuracy, durability, and eco-friendliness. In winter, neglecting oil changes or refueling can make the engine difficult to start or even cause severe engine damage.

3. Avoid using fire to heat the oil pan. For guardrail pile drivers, direct fire heating is not allowed to prevent fire hazards. Starting the engine in this manner can suck ash and hard particles into the cylinder through the air pipe, leading to valve sealing issues and accelerated cylinder wear, a common component failure type.

4. Limit the use of electric glow plugs and flame preheaters. Both use electric heating elements (e.g., Fe-Cr-Al alloy wire, Ni-Cr alloy wire) which consume a lot of electricity and generate significant heat. Prolonged use can damage the battery due to intense discharge and burn out the heating element. Thus, glow plugs should not be used for extended periods.

5. Direct oil addition into the cylinder of the guardrail pile driver, a new type of all-hydraulic piling equipment with excellent energy-saving and environmental protection performance, reflects its high quality, efficiency, energy conservation, and longevity in installing highway barriers across various complex strata.

6. Avoid high-speed operation immediately after starting. When the engine starts, the oil is cold and less fluid. Immediate high-speed operation can cause severe wear on moving parts due to lack of lubrication, a basic form of component failure.

7. Avoid sudden engine shut down under full load, which can lead to bearing burnout and seizing under severe conditions.

When the engine operates at high speeds, the expelled air pressure is compressed into the engine by the turbocharger, enhancing fuel combustion and generating powerful output. The turbocharger also reaches high temperatures and requires cooling. Sudden engine shutdown can stop oil flow instantly, preventing timely cooling of the radiator turbocharger and causing turbo damage.
