With the addition of concrete laser leveling machines in the construction industry and road construction industries, there has been a qualitative leap in both quality and speed, and it has also saved a lot of costs for users. However, in the face of high-frequency use, users cannot ignore the cleaning of the equipment. This step must not be sloppy. Let's take a look at how to clean the leveling in a few steps! 1 The liquid crystal surface on the laser leveling machine body also needs to be cleaned. You can use organic resin or lens cleaning cloth to wipe off the dirt. If there is too much dirt, it can be removed with a lens cleaning solution. 2 After the laser leveling machine is constructed, there will be a lot of dust and mud. First of all, the dust on the laser leveling machine should be wiped clean, and the dirt and oil stains should be wiped clean with tissue paper or cotton cloth. 3   If the laser signal is lost during the construction of the laser leveling machine, the machine needs to be restarted, and the interval should be more than ten seconds.  4 If there are too many stains, you can use a soft cloth to soak in water diluted with a neutral detergent, wring it out and clean it. The best laser leveling machine manufacturers remind you not to use volatile oil, thinner, gasoline, etc. Chemical cleaning wipe.   The laser leveling machine uses a scraper to take away the raised concrete and initially level it to reach the elevation required by the design. The hydraulically driven vibrating motor vibrates at a frequency of 4000 times per minute, driving the entire vibrating plate to vibrate the concrete together. The leveling of the laser paver does not need to pull the control line, nor does it need the side formwork to control the ground elevation, but is controlled by the laser measurement and control system on the laser leveling machine in real time. As long as the laser transmitter is not disturbed, no matter where the laser leveling machine moves Wherever it is, it can be ensured that the overall elevation of the paved ground will not be affected. The concrete ground laser leveling machine is to spread the mixed concrete along the subgrade according to the given thickness, width and road type requirements, and then complete the construction of paving the concrete road surface through the operation procedures of vibrating, leveling and troweling. mechanical. The working device of the concrete floor laser leveling machine generally consists of a distributor, a scraper, a vibrator (including a vibrator and a vibrator), a leveling machine, a trowel and other devices. At the same time, it also requires the organic cooperation of the frame, walking mechanism, manipulation control system and other auxiliary mechanisms. Some models integrate all the devices into one, and some are divided into two or more independent stand-alone machines.        

    If the laser signal of the concrete laser leveling is lost, in most cases, you can first check it step by step by yourself. If the problem still cannot be solved after checking, you need to contact professional maintenance personnel. The core troubleshooting logic is "gradually locating from the signal source to the receiving end", first eliminating external interference and simple connection issues, and then determining hardware faults. Troubleshooting in the following order can solve over 80% of signal loss problems without the need for professional tools: Check the status of the laser emitter Confirm whether the transmitter is powered on and whether the power indicator light is on normally (if it is not on, check whether the power cord is plugged in tightly and whether the power adapter is damaged). Observe whether the transmitter is placed horizontally and whether the bottom leveling bubble is in the center (tilting will cause signal deviation, and manual leveling needs to be re-done or the automatic leveling function should be enabled). Investigate signal occlusion and interference Check if there are any obstacles such as steel bars, construction tools, personnel, etc. between the transmitter and the receiving probe of the leveling machine, and clear the straight area between the two. Stay away from other strong light sources or electromagnetic equipment, such as electric welding machines, large frequency converters, and powerful flashlights, as these devices can interfere with the laser signal. Check the connection of the receiving system Check whether the laser receiving probe on the leveling machine is loose or displaced, and whether there is dust or concrete slurry on the probe lens. Wipe the lens with a clean soft cloth. Check the connection cable between the probe and the main unit, and confirm whether the plug is tightly inserted and whether the cable is damaged (if the cable is damaged, it can be temporarily wrapped with insulating tape, and needs to be replaced later). Restart the device and restore factory Settings Turn off the power of the transmitter and the leveler, wait for 1 to 2 minutes, and then restart them. Some temporary signal disorders can be resolved by restarting. If restarting is ineffective, refer to the equipment manual and restore the laser control system to its factory Settings (Note: Record the commonly used parameters before restoring). Test the signal receiving range Move the leveler to a position close to the transmitter (such as within 3 to 5 meters) and observe whether the signal can be received. If it can receive at close range but not at long range, it might be due to insufficient power of the transmitter or a decrease in the sensitivity of the probe. Further hardware testing is required. If the signal is still lost after completing the above troubleshooting, it indicates a hardware fault. It is not recommended to disassemble it by yourself. Please contact the maintenance personnel Transmitter failure: For instance, if the laser tube of the transmitter burns out or the internal circuit board is damaged, it will be manifested as no laser being emitted after power-on, or the laser intensity significantly weakening. The receiving probe is damaged: The internal photosensitive element of the probe is faulty. Even without obstruction, it cannot receive signals. The sensitivity of the probe needs to be tested with a dedicated instrument. Host control system failure: The communication module between the host and the receiving system is damaged, which is manifested as a direct error "signal interruption" after the equipment is turned on. Professional personnel are required to inspect the circuit or replace the module.   Note: The parameters provided in this document are for reference only and are not mandatory. Due to differences in technical characteristics between different brands and models of laser levelers, please consult the manufacturer for a suitable solution before actual operation.
