The HA100-4L is a commonly used four-wheeled concrete laser screed in floor construction. The installation, commissioning, and standardized operation of the entire machine directly affect the flatness of the floor, construction efficiency, and equipment lifespan. The entire process follows a standardized logic of "first, start the machine; then, assemble the working head; finally, calibrate the laser system; and finally, debug the machine." Throughout the process, attention must be paid to component docking, wiring connections, safety locking, and precision control. Specific operational points are as follows:
I. Initial Machine Start-up and Preheating
Before starting, complete a basic inspection, focusing on confirming that all buttons on the control panel are reset to their original positions without jamming or sticking. Then, turn on the machine power, pull out the power switch under the driver's seat, moderately increase the throttle, pull out the black choke button next to the power switch, pull the choke outward, and turn the key to start the machine. After the machine starts normally, increase the throttle again and simultaneously push the choke back inward. Operate the forward and reverse levers to test the machine's walking function; if it is normal, prepare for subsequent working head installation.
II. Working Head Assembly and Hydraulic Connection
Move the machine body directly above the working head, precisely aligning it with the bottom docking groove. Lower the machine body gradually using the right-side hydraulic lift, prioritizing the docking of the right-side working head. Before installation, test insert the pin to check if the docking holes are aligned. If the pin cannot be inserted smoothly, adjust the height of the right-side hydraulic lifting rod using the "Right Leveling" button on the control panel for fine-tuning. After aligning the holes, install the matching steel sleeve and use a hammer to firmly drive the pin in. After the pin is fully inserted, ensure the safety lock is securely fastened to prevent it from falling off during operation. The left-side working head uses the exact same installation method, ensuring horizontal alignment and proper locking throughout the process.
III. Quick Connection of Pipelines and Lines
After the mechanical docking of the working heads is completed, proceed to the pipeline and line connection stage. Use the standard quick-connect couplings provided with the equipment throughout the process, requiring no additional tools. First, connect the hydraulic hoses. Pull down the quick-connect clips, align the connector with the interface, insert it, and tighten the clips to complete the hydraulic circuit sealing connection. Next, connect the vibration cable, align it with the interface, tighten it securely, and use cable ties to secure the cable to prevent loosening during operation. Finally, connect the angled cable, aligning the wider groove of the connector with the socket, and tighten the clips to secure it. Distinguish between different cable interfaces to avoid reverse insertion, ensuring all electrical, hydraulic, and signal lines are connected correctly.
IV. Laser System Installation and Elevation Setting
The laser system is crucial for leveling accuracy. First, set up the tripod and adjust the legs to be level. Observe that the top level bead is within the coil; this indicates it meets the standard. Align the laser transmitter with the bottom screw hole and tighten the fixing screws to lock it. Adjust the tripod height to the 1.8-2.5 meter range to suit most flooring construction scenarios. Press the green power button; the transmitter will automatically start and complete autonomous leveling. Next, install the digital receiver, fix it to the handheld lever, and tighten the screws. Calibrate the handheld lever to level, and set the zero-point elevation according to the benchmark provided by the client. After calibration, the machine can proceed to the overall debugging stage.
V. Overall Machine Accuracy Debugging and Functional Testing
Restart the machine and repeat the initial startup procedure. After confirming that the throttle and air damper are operating correctly and the machine is running smoothly, proceed to the control panel for debugging. Press the automatic mode button and wait 3-5 seconds for system response. Hold the digital receiver close to the working head and adjust the height of the left and right hydraulic lifting rods using the "Left Leveling" and "Right Leveling" buttons on the panel, calibrating each side to the zero-point elevation. Repeatedly test both sides to ensure the horizontal accuracy meets the standard.
After accuracy calibration, install the aluminum rods for the receivers on both sides, extend them to the appropriate length, and tighten the fixing screws. Mount the digital receiver on the aluminum rod, with the receiver facing the driver's seat for easy operation and observation. Connect the dedicated threaded cable, distinguishing between the plugs with holes and those with pins. Connect the plug with holes to the receiver and the plug with pins to the machine body interface. Align the notch, insert, and tighten the buckle to prevent signal interruption. Finally, fine-tune the receiver height, loosen the fixing screws, and move it up and down until the green light in the middle is constantly on (a red light indicates it's too low and needs to be pushed up, a yellow light indicates it's too high and needs to be lowered). Adjust both sides until the green light is stably lit, then tighten the screws to lock the position.
VI. Functional Acceptance and Standardized Engine Shutdown
After the entire machine is installed and debugged, start the machine to test the core functions such as vibration, lifting, and movement of the working head. Confirm that there are no jams, no oil leaks, stable signal transmission, and that the leveling accuracy meets the construction requirements. Standardized engine shutdown must follow this procedure: First, adjust the throttle to minimum, press the reset button on the control panel, confirm that all function keys are in the off position, turn the key to disconnect the power, and finally push the power switch under the driver's seat inward to complete the engine shutdown. Directly disconnecting the power to shut off the engine is strictly prohibited to avoid damaging the equipment's circuitry and engine.
