  Equipment inspection: Confirm that the laser transmitter, leveling machine head, vibrator, travel system and other components are operating normally and that the battery/fuel is sufficient. Benchmark setting: Arrange fixed points (such as steel chisels) around the construction area, install the laser transmitter and calibrate the level to ensure that the laser covers the entire work surface. Concrete paving: Use a dump truck or a spreader to evenly spread the concrete to the designed thickness (usually 2-3cm higher than the leveling machine scraper height), and ensure that the concrete slump meets the requirements (generally 120-180mm). Start the equipment: Turn on the laser receiver, adjust the scraper to the preset height, and start the vibration and leveling functions. Straight line operation: The operator controls the equipment to travel in a straight line at a uniform speed along the long side, and the laser system automatically adjusts the scraper height to complete the vibration and rough leveling. Cross operation: After the initial leveling, repeat the operation in the vertical direction to eliminate surface ripples. For corners and column root areas that cannot be covered by the laser leveler, first use a scraper to manually scrape and then use a small vibrating beam to assist in compaction. After the operation is completed, turn off the equipment and clean the residual concrete on the surface. Immediately cover with a film or spray a curing agent to prevent the concrete from losing water too quickly.   Equipment inspection: Confirm that the trowel motor, blade/disc, protective cover and other components are intact, and the fuel/battery is sufficient. Confirmation of concrete status: There is a slight indentation on the concrete surface when pressing with fingers, but it is not sticky (initial setting stage), and there is no water seepage on the surface. Environmental control: In hot and dry weather, water should be sprinkled in advance to moisten the ground to avoid dust. Initial slurry lifting: Install the disc, adjust the speed to 600-800rpm, move slowly from the edge to the center, overlap 1/3 of the working width, and eliminate surface bumps. Secondary compaction: After the concrete strength increases slightly, reduce the speed to 400-600rpm, raise the slurry and compact it again to ensure a uniform surface. Angle adjustment: first adjust the blade angle to 10-15°, finish at low speed (300-400rpm), and gradually increase the angle to 25-30° to improve the surface density. Finishing in multiple passes: usually 2-3 times, with an interval of about 30 minutes between each pass, subject to the concrete surface strength. For areas that cannot be reached by machinery, use a handheld trowel or manual trowel to finish. After the operation, thoroughly clean the concrete residue on the blade/disc and check the bearing lubrication.   The laser leveling machine must be completed before the initial setting of the concrete (about 1-2 Hours), the trowel machine needs to start after the initial setting to avoid sanding too early or difficulty in finishing too late. Strictly control the slump and setting time of concrete to avoid affecting the leveling effect due to material problems. The operator needs to wear protective equipment such as non-slip shoes and goggles. Personnel are prohibited from entering the working area when the equipment is moving. The operation speed should be accelerated in hot weather to avoid the concrete surface hardening too quickly; construction should be suspended on rainy days and unsolidified concrete should be covered. Surface sanding: Check whether the trowel machine is operated too early or the concrete water-cement ratio is too high. Local unevenness: Correct by manual filling or secondary vibration. Through standardized operation and detail control, the concrete surface flatness can be ensured to be within ±3mm/3m, meeting the high-precision requirements of industrial plants, commercial floors, etc.
