When a highway guardrail pile driver enters the work area, there should be no high-voltage power lines present. The work area should be clearly marked or fenced off, and non-operational personnel must not enter. During the hammering process, operators must supervise from a distance of more than 5 meters from the pile hammer. Before operation, the landing gear should be used to lift the upper piston slightly higher than the upper cylinder, open the oil reservoir cap, and fill up with lubricating oil as per regulations. For actively lubricated pile hammers, a special oil pump should be used to add lubricating oil to the lubrication pipeline, and air in the pipeline should be expelled.

For newly deployed pile hammers, 0.5L of lubricating oil should be poured around the upper piston beforehand, and a certain amount of lubricating oil should be added to the lower piston using an oil gun. All tightening bolts should be checked, with special attention given to the fixing bolts of the guide plate, and operation should not proceed in the event of looseness or missing parts. Ensure that the landing gear and other working organizations are safe and reliable, with the starting hook and upper piston contact line between 5-10mm.

During operation, special attention should be paid to whether the lubricating oil of the upper piston is leaking from the oil hole. When the lower cylinder is lubricated by an active oil pump, the oil pipe head should be frequently opened to check for oil spray; if there is no active oil pump, lubricating oil should be added to the lubrication point of the lower piston every 15 minutes. If the time to drive a single pile exceeds 15 minutes, lubricating oil should be added immediately after completion. Before starting the pile hammer, ensure that the pile hammer, pile cap, and pile are on the same axis, and avoid skew piling.

When starting the pile hammer in soft soil layers with greater penetration, first close the throttle and hammer coldly, then open the throttle and start the pile hammer when the penetration per hit is less than 100mm. During piling, a dedicated person should be responsible for controlling the rope on the articulated arm; in case of emergencies, the control rope can be used for an urgent stop. When the water in the water jacket is lower than the intake and exhaust ports of the lower cylinder due to evaporation, it should be replenished in time, and operation without water is prohibited.

After driving the pile, the verticality of the pile should be promptly corrected. If the pile is driven more than 3m into the soil, do not use the highway guardrail pile driver to correct the tilt of the pile by moving it. Ensure that the landing gear and other working organizations are safe and reliable, with the starting hook and upper piston contact line between 5-10mm. During hammering, the maximum jump height of the upper piston should not exceed the factory manual specifications.
