After checking the mechanical and hydraulic systems, and ensuring the diesel engine's water tank level and oil level are normal, the diesel engine can be started. Run the machine at low speed without load for 3-5 minutes before starting work.
The chassis is driven by a hydraulic motor with stepless speed regulation. Different travel speeds can be obtained by adjusting the diesel engine speed and fuel supply (controlled by a manual valve). Pushing the combination valve handle forward moves the chassis forward, and pulling it back moves it backward. The remaining cylinders-the lower boom lifting cylinder, the upper frame lateral cylinder, the column tilting cylinder, and the boom extension cylinder-are each controlled by a combination valve handle; pushing the handle forward extends the piston rod, and pulling it back retracts the piston.
Upon arrival at the site, check if the column is vertical. If not, adjust it using the tilting cylinder (or diagonal tie rod) and lateral screws. Lock the column with diagonal cables on both sides. Observe the column's orientation constantly during pile driving and relocation.
Adjust the chassis's longitudinal position and the column's lateral position to bring the column to the designated orientation.
Raise the hydraulic hammer to its highest point, place the lower part of the steel pipe pile on the pile position, align the upper part with the pile head of the hydraulic hammer, and press down on the steel pipe pile. Then, begin hammering. Maintain pressure on the steel pipe pile with the pile head until the pile is driven to the specified size.
Due to the harsh working environment and high impact vibration of this machine, the dynamics of all parts should be observed constantly during operation. If abnormal noise or other abnormal phenomena occur, stop the machine immediately for inspection. Operation can only resume after the fault has been rectified. If leaks are found in the hydraulic system joints or loosening of components, stop the machine for adjustment and tightening. Operation can resume after the problem is resolved.
Before the end of each shift, lower the hydraulic hammer to its lowest position, and retract all other cylinders and piston rods to their shortest length. If moving to a different location, the column should remain tilted back.
Regular inspections should be performed on the actuators, accessories, and electrical components of the guardrail pile driver, especially the connections at the motor wiring section.
