The Maintenance Work Must Not Be Ignored To Ensure The Leveling Effect Of The Concrete Laser Leveling Machine

In a low-temperature winter environment (typically referring to an ambient temperature of ≤5℃), concrete laser leveling machines are prone to difficulties in starting due to issues such as increased oil viscosity, battery discharge, and fuel solidification (for diesel models). Maintenance should be carried out from four dimensions: "protection of the starting system, optimization of oil performance, anti-freezing of core components, and protection of idle storage". The specific measures are as follows:   At low temperatures, the battery capacity will drop significantly (for every 10℃ drop in temperature, the capacity approximately decreases by 10% to 15%), and the load on the starting motor increases, which is the main reason for the difficulty in starting. Special protection is required: Check the battery status: Use a multimeter to measure the battery voltage. For a 12V battery, it should be ≥12.4V (fully charged state). If the voltage is lower than 12V, immediately use a dedicated low-temperature charger (to avoid the low charging efficiency of ordinary chargers) to recharge the battery. If the battery has been in use for more than two years, it is prone to "quick discharge" at low temperatures. It is recommended to replace the battery with a new one in advance (to avoid failure when starting temporarily). Prevent the battery from cracking due to freezing: The freezing point of the battery electrolyte varies with its concentration (if the concentration is too low, it may freeze and crack the casing). Check the electrolyte level (if it is below the scale line, add distilled water; do not add tap water or electrolyte). If necessary, test the density of the electrolyte (use a hydrometer, standard value 1.26-1.28g/cm³; if the density is low, adjust the concentration). Clean the battery connection: If there is white sulfide (which is prone to condensation at low temperatures) at the connection, rinse it with hot water, then sand it clean with sandpaper, and apply vaseline or battery protector (to prevent re-oxidation and ensure smooth current conduction). Check the terminal blocks of the starting motor: Ensure that the bolts are tightened (metal shrinks and is prone to loosening at low temperatures, resulting in poor contact). If the terminal blocks are oxidized, they need to be sanded with sandpaper. Manually rotate the starting motor gear to ensure there is no jamming (to avoid poor gear meshing at low temperatures). Additional inspection for diesel models: Check if the start preheater (if any) is functioning properly – after power-on, the preheater indicator light should be on. If it is not on, check the circuit or replace the preheater (the preheater can increase the temperature inside the cylinder, help diesel atomize, and avoid difficulties in cold starting). Low temperatures can cause a sharp increase in the viscosity of engine oil, hydraulic oil and diesel, resulting in slow flow and difficulty in oil suction by the pump body. It is necessary to ensure the fluidity of the oil through "oil change + preheating". Replace with low-grade diesel: Select the corresponding grade based on the ambient temperature (for example, -20 # diesel for -10 ℃ to -20℃ and -35 # diesel for -20℃ to -35 ℃), to prevent diesel from solidifying in the fuel tank or fuel line (solidification can cause fuel supply interruption and prevent starting). If high-grade diesel has been added, diesel pour point depressant should be added (add it in the proportion specified in the manual to lower the freezing point of the diesel). Fuel system preheating: Before starting, you can first turn on the ignition switch (without starting the engine), and let the fuel pump be powered on to work for 30 seconds (some models have a "fuel preheating" mode), allowing the diesel to preheat and flow in the fuel pipes. If the diesel in the fuel tank has slightly solidified, a small amount of low-grade diesel or kerosene (not exceeding 10%) can be added to the tank to help dilute and melt it. Do not add gasoline to avoid safety risks. Type of oil Maintenance measures Engine oil 1. Switch to winter-specific low-temperature engine oil (such as 5W-30, 10W-30, the smaller the number before the viscosity grade, the better the low-temperature fluidity) to prevent the original summer engine oil from having excessive viscosity at low temperatures, which could increase the engine's starting resistance. 2. Before starting, if the ambient temperature is ≤-10℃, you can first heat the engine oil through the engine preheater (external or built-in) for 30 to 60 minutes, or pour hot water over the oil pan (water temperature 50 to 60℃, do not use boiling water) to reduce the viscosity of the engine oil. Hydraulic oil 1. Replace it with low-temperature anti-wear hydraulic oil (such as L-HV46, L-HV32, which has better low-temperature fluidity than ordinary hydraulic oil) to prevent the hydraulic oil from getting stuck at low temperatures, which could lead to the failure of the leveling scraper and the walking action. After starting the equipment, let the hydraulic system run idle for 5 to 10 minutes (operate the handle to slowly extend and contract the cylinder). When the temperature of the hydraulic oil rises above 10℃, then carry out load operation to avoid damage to the hydraulic pump due to dry grinding at low temperatures. In winter, the air humidity is high, and moisture is likely to remain inside the equipment. Freezing at low temperatures can cause components to get stuck or break, so targeted protection is needed Laser transmitter/receiver: When not in use, it should be stored indoors (to avoid low temperature and moisture in the open air). Before use, check if there is any ice inside (if there is, it needs to be thawed naturally indoors. Do not use open flames to bake it to avoid damaging electronic components). Before powering on, wipe the casing and lens with a dry soft cloth to ensure there is no moisture residue. Control circuit: Check if there is any condensation water at the circuit joints (if so, dry it with a hair dryer using cold air). Wrap the joints with waterproof insulating tape to prevent water from seeping in and causing short circuits, which may affect the transmission of laser signals. Hydraulic oil tank: Check whether the seal of the oil tank cover is intact (to prevent rainwater or snow water from seeping in). If water is mixed into the hydraulic oil, it will freeze at low temperatures, blocking the oil pipes or damaging the hydraulic pump. It is necessary to regularly drain the accumulated water at the bottom of the oil tank (open the oil tank drain valve, release a small amount of oil, and observe whether there is any water sedimentation). If there is too much water, all the hydraulic oil needs to be replaced and the oil tank cleaned. Engine cooling system (diesel model) : Antifreeze must be used (tap water or ordinary water is not allowed). The antifreeze should be mixed in a ratio of "antifreeze + distilled water = 1:1" (the freezing point can be reduced to around -35 ℃). Check the antifreeze level (it should be between "MIN" and "MAX" in the expansion tank). If the level is insufficient, add the same type of antifreeze. Prevent the cooling system from freezing and cracking the water tank or cylinder block.   Hydraulic oil tank: Check whether the seal of the oil tank cover is intact (to prevent rainwater or snow water from seeping in).

Prevent the cooling system from freezing and cracking the water tank or cylinder block. First startup: If the ambient temperature is ≤-15℃, do not start directly. First, perform the "three-step preheating" : ① Connect the power supply and turn on the preheater (if available) for 30 seconds; Turn off the preheater, wait for 10 seconds, and repeat 2 to 3 times. ③ Gently press the accelerator (for diesel models), slowly turn the start key. If the start fails in one attempt, wait for 1-2 minutes and then try again (to avoid overheating and damage to the starting motor due to continuous operation). Do not start continuously more than three times. After starting: After the engine starts, it should idle for 10 to 15 minutes (do not accelerate immediately). Wait until the water temperature rises above 40℃ and the oil pressure is normal (the pointer is stable within the standard range), then operate the hydraulic system and traveling mechanism to gradually adapt the equipment to the low-temperature environment. If the battery is discharged and the device cannot be started: It can be started by jumper connection (use the battery of another device, connect the positive terminal to the positive terminal and the negative terminal to the negative terminal. After starting, keep the idle speed for 15 minutes to charge the discharged battery). Do not jumper for a long time to avoid damaging the electrical system. If the diesel solidifies and causes the fuel supply to be interrupted: The equipment should be moved indoors (temperature ≥5℃) to allow the diesel to melt naturally, or low-grade diesel can be added to the fuel tank for dilution. After the diesel flows normally, press the fuel pump to expel the air in the fuel pipe, and then try to start it. If the hydraulic system gets stuck: After starting, run the hydraulic system unloaded first. If it still gets stuck, check the temperature of the hydraulic oil (if it is below 0℃). You can heat the hydraulic oil by connecting an external heater (placed outside the hydraulic oil pipe). Wait until the temperature rises above 10℃ before operating. Through the above measures, the problem of difficult start-up in winter due to low temperatures can be solved from four aspects: "start-up source, oil, components, and operation". At the same time, it can reduce the hidden damage to the equipment caused by low temperatures and ensure the stability and accuracy of the laser leveling machine machine during winter construction.   Note: The parameters provided in this document are for reference only and are not mandatory.
