    The engine is the "heart" of the leveling machine. Proper maintenance is of vital importance, which can effectively extend the service life of the equipment, ensure construction efficiency and reduce maintenance costs. The following is a detailed summary of the key points for engine maintenance and the oil change cycle for you Maintenance work can be divided into three parts: daily maintenance, weekly/monthly maintenance and long-term storage maintenance. Machine inspection: Before starting, run the machine once to check for oil or water leakage and whether any components are loose or damaged. Check the engine oil level Park the machine on a level ground, turn off the engine and let it stand for 10 to 15 minutes to allow the engine oil to flow back to the oil pan. Pull out the oil dipstick, wipe it clean with a clean cloth, insert it again and pull it out. Check if the oil level is between the "upper limit" (FULL/Max) and "lower limit" (LOW/Min) marks on the dipstick. When insufficient, it should be added to the upper limit position, but must not exceed. Check the coolant level When the engine is cooling, check whether the water level in the expansion tank is between the "FULL" and "LOW" marks. If it is too low, add the same brand and model of antifreeze coolant. Do not directly add tap water to avoid the formation of scale and rust. Check the air filter Check the vacuum indicator on the air filter housing. If the indicator window turns red, it indicates that the filter element is clogged and needs to be cleaned or replaced immediately. In construction sites with extremely high levels of dust, the air filter elements should be cleaned every day or even after each shift. Check the fuel system Check the fuel level in the fuel tank and replenish it in time. Open the water drain valve of the fuel filter to drain the accumulated water and impurities at the bottom. (For oil-water separators with manual pumps, pump the oil to release air first and then drain the water.) Clean the machine: After the operation is completed, promptly clean the cement, dust and debris on the engine surface and radiator to ensure good heat dissipation. Change the engine oil and oil filter: For details, see Part Two. Clean/Replace the air filter Remove the filter element and repeatedly blow and wash it from the inside out with low-pressure compressed air (pressure < 0.5MPa). Do not strike the filter element. If the filter element is damaged, severely contaminated with oil or the indicator still alarms after cleaning, it must be replaced immediately. Replace the fuel filter It is usually replaced every 250 to 500 hours. After replacement, be sure to expel all the air in the fuel line to ensure a smooth start. Check and tighten the fan belt Check if the belt has any cracks or wear. Press the middle of the belt with your finger. The deflection (downward pressure distance) should be between 10 and 15mm. Both being too loose and too tight will affect the normal operation of the water pump and fan. Check the battery Check whether the battery terminals are securely fastened and free from corrosion (vaseline can be applied for protection), and whether the electrolyte level is normal (this operation is not required for maintenance-free batteries). This is a question without a fixed number of days for the answer. The optimal cycle depends on the "engine working hours" and the "working environment". Primary reference: Equipment user manual The maintenance cycles of engines of different brands and models vary. Please be sure to refer to the "User and Maintenance Manual" of the equipment you purchased. This is the most authoritative basis. General reference standard Standard operating conditions: If your leveling machine operates in an environment with little dust and normal load, the general replacement cycle is every 200 to 250 working hours. Harsh working conditions: If your equipment operates for a long time in the following environments, the replacement cycle should be shortened to 150 hours or even shorter: High-dust environments: such as cement grinding and construction sites with heavy sand and dust, dust can accelerate the deterioration of engine oil. Continuous heavy-load operation: Long-term high-intensity leveling. Frequent starts and stops. How to determine if the engine oil needs to be changed? Dipstick observation method: Near the replacement cycle, pull out the dipstick and drop a drop of engine oil onto a white paper towel. Observe the situation after the oil droplets have spread: The color of the central oil ring: If it is dark black and contains many impurities, it indicates that the engine oil is severely dirty. Diffusion ring boundary: If the boundary is unclear and there is no obvious three-layer diffusion ring, it indicates that the dispersibility of the engine oil has declined. The hand feel method: Rub the engine oil with your fingers. If you feel a distinct granular sensation or it loses its stickiness and smoothness, it indicates that there are too many impurities or it has lost its effectiveness. Important Notice The engine oil and filter must be replaced simultaneously! If only the engine oil is changed but the oil filter is not, the dirty oil in the old oil filter will quickly contaminate the new oil. Use the specified grade of engine oil: According to the season and local temperature, select the CF-4, CH-4 or higher grade diesel engine oil recommended in the manual. If the equipment is planned to be parked for more than one month, the following measures should be taken: Drain all the coolant and engine oil from the engine. Inject approximately 15ml of clean engine oil into each cylinder through the intake port and rotate the crankshaft several times to form an oil film on the inner walls of the cylinders for rust prevention. Fill the fuel tank to the brim to prevent condensation of water droplets and disconnect the negative terminal of the battery. Clean the entire machine thoroughly and park it in a dry and well-ventilated room. For the engine maintenance of diesel concrete laser leveling machines, please keep in mind: Regular inspection: Daily checks of oil, water and air are the foundation. Regular replacement: Follow the instructions and replace the engine oil, oil filter, fuel filter and air filter regularly according to the working hours. Under standard operating conditions, changing the engine oil and oil filter every 200 to 250 hours is a safe reference value. Heavy environmental conditions: Under harsh working conditions, the maintenance cycle should be shortened. Use genuine products: Use genuine oil products and filter elements that meet the specifications. By developing good maintenance habits, your equipment will be able to serve you for a longer time and more efficiently.   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. This reference document assumes no responsibility for any issues arising from failure to follow the manufacturer's instructions.    

What are the construction characteristics of laser leveling machine? The precision laser leveling machine is developed according to the increasing demand for ground quality such as strength, flatness, levelness, etc. of modern industrial plants, large shopping malls, warehouses and other large-area cement concrete floors. The leveled cement concrete floor is paved with the VANSE precision laser leveling machine, and the quality of the ground paved by conventional methods is much better – the flatness and levelness of the ground are increased by more than 3 times, and the compactness and strength are increased by 20% above. At the same time, it can also improve work efficiency by more than 50%, and save about 35% of labor. In addition, it can easily place high-strength concrete, low-slump concrete and fiber cement concrete. Its laser system is equipped with a variety of automatic control components to monitor the elevation of the leveling head in real time at a frequency of 10 times per second to ensure that the flatness and levelness of the ground for paving are effectively controlled. At the same time, the vibrating frequency of its powerful vibrator reaches 3000 times/min, which ensures that the concrete is vibrated and compacted, so that the entire paved concrete matrix is homogeneous and dense. Laser leveling machine features:   01 The leveling principle of the laser leveling machine is realized under the automatic control of the computer by using precision laser technology, closed-loop control technology and highly precise hydraulic system. This is the most prominent difference between it and other floor construction processes. specialty. 02 The leveling principle of the precision laser leveling machine is to rely on the leveling head driven by hydraulic power, cooperate with the laser system and the computer control system to complete the leveling work while automatically leveling. The leveling head is equipped with an integrated scraper, vibrator and leveling plate, which integrates all leveling, leveling, vibration and compaction work, and completes it at one time. The computer control system automatically adjusts the elevation 10 times per second in real time, and the vibration frequency of the vibrator with a balanced design reaches 3000 times per minute. The leveling accuracy is 40 extension meters and the control is below 3mm 03 The laser transmitter used to control the ground level is arranged independently, so that the level of the ground is not controlled by the template, and no cumulative error will occur. 04 The laser leveling machine can also automatically control the longitudinal and transverse slopes, which is also completed by the laser system, computer system, hydraulic system, and mechanical system. For complex-shaped ground with high requirements such as drainage, a three-dimensional special-shaped ground treatment system can also be selected to achieve it.
