冷再生机作为道路施工的重要设备，租赁期间的每日保养直接影响次日施工效率与设备寿命。施工结束后，需围绕核心系统开展针对性保养，确保关键部件处于良好状态。

　　As an important equipment for road construction, the daily maintenance of the cold recycling machine during the lease period directly affects the construction efficiency and equipment life of the next day. After the construction is completed, targeted maintenance should be carried out around the core system to ensure that key components are in good condition.

　　整体清洁与外观检查是基础环节。先用高压水枪冲洗设备表面的泥土、沥青碎屑（避开电气接口、仪表盘等部位，防止进水短路），清理铣刨鼓、输送带及底盘附着的杂物（若有硬化的沥青块，可用铲刀轻轻剥离，避免划伤设备表面）。检查机身有无明显磕碰、变形，连接部位的螺栓是否松动（如铣刨鼓防护罩、液压油管固定夹），发现问题及时紧固或记录报备。

　　Overall cleaning and visual inspection are fundamental steps. First, use a high-pressure water gun to rinse the soil and asphalt debris on the surface of the equipment (avoiding electrical interfaces, instrument panels, and other parts to prevent water ingress and short circuits). Focus on cleaning the debris attached to the milling drum, conveyor belt, and chassis (if there are hardened asphalt blocks, gently peel them off with a shovel to avoid scratching the equipment surface). Check if there are any obvious bumps or deformations on the body, and if the bolts at the connecting parts are loose (such as the milling drum protective cover and hydraulic oil pipe fixing clip). If any problems are found, tighten them in a timely manner or record and report them.

　　发动机系统保养需细致操作。待发动机冷却常温后，检查燃油箱油量（补充油箱容积的 80% 以上，避免油箱内壁因夜间冷凝产生水分），同时排放燃油滤清器内的积水（打开放水阀无气泡流出）。查看机油液位与油质（机油尺刻度应在上下限之间，若机油呈乳状或含杂质，需及时更换），清理空气滤清器滤芯（用压缩空气从内向外吹除灰尘，若滤芯破损或过脏则更换新件）。检查冷却液液位，确保在膨胀水箱刻度线范围内，补充时需使用同型号冷却液，避免混用导致腐蚀。

　　Engine system maintenance requires meticulous operation. After the engine cools down to room temperature, check the fuel level in the fuel tank (fill it to more than 80% of the tank capacity to avoid water condensation on the inner wall of the tank at night), and drain the accumulated water in the fuel filter (open the drain valve until there are no bubbles flowing out). Check the oil level and quality (the oil dipstick scale should be between the upper and lower limits. If the oil is milky or contains impurities, it needs to be replaced in a timely manner), clean the air filter element (use compressed air to blow away dust from the inside out. If the filter element is damaged or too dirty, replace it with a new one). Check the coolant level to ensure it is within the range of the expansion tank scale. When replenishing, use the same type of coolant to avoid mixing and causing corrosion.

　　工作装置维护聚焦铣刨与输送系统。清理铣刨鼓内残留的石料、钢筋等异物（可转动鼓体逐齿检查，用钢丝刷清理齿座内的碎屑），检查铣刨齿磨损情况（若刀刃磨损超过原尺寸的 1/3 或出现崩裂，应及时更换，更换时需涂抹专用润滑脂）。查看输送带表面有无撕裂、跑偏痕迹，调整张紧度（用手按压输送带中部，下沉量以 10-15 毫米为宜），清理输送带滚筒上的黏附物（防止次日启动时输送带打滑）。

　　Work equipment maintenance focuses on milling and conveying systems. Clean up the remaining stones, steel bars, and other foreign objects inside the milling drum (rotate the drum body to check tooth by tooth, use a wire brush to clean the debris inside the tooth seat), and check the wear of the milling teeth (if the blade wear exceeds 1/3 of the original size or cracks occur, it should be replaced in a timely manner, and special lubricating grease should be applied during replacement). Check for any signs of tearing or deviation on the surface of the conveyor belt, adjust the tension (press the middle of the conveyor belt by hand, with a sinking amount of 10-15 millimeters), and clean the adhesive on the conveyor belt drum (to prevent the conveyor belt from slipping when starting the next day).

　　液压与润滑系统检查不可忽视。检查液压油箱油位（需在设备静置 30 分钟后查看，油位应介于液位计上下刻度之间），观察液压油颜色（正常为淡黄色，若呈深褐色或有杂质，需及时联系租赁方处理）。查看液压管路有无渗漏（检查接头、软管弯曲处），若发现油渍需用抹布擦拭后标记，次日施工前进一步排查。按设备说明书要求，对各润滑点加注润滑脂（如铣刨鼓轴承、输送带轴承座），注油时缓慢按压黄油枪，直新脂从缝隙溢出（避免过量加注导致密封件损坏）。

　　The inspection of hydraulic and lubrication systems cannot be ignored. Check the oil level in the hydraulic oil tank (it should be checked after the equipment has been idle for 30 minutes, and the oil level should be between the upper and lower scales of the level gauge), and observe the color of the hydraulic oil (normally light yellow, if it is dark brown or has impurities, contact the lessee in a timely manner for handling). Check for leaks in the hydraulic pipeline (with a focus on checking the joints and bent hoses). If oil stains are found, wipe them with a cloth and mark them. Further investigation should be carried out before construction the next day. According to the equipment manual, add lubricating grease to each lubrication point (such as milling drum bearings and conveyor belt bearing seats). When adding oil, slowly press the grease gun until new grease overflows from the gap (to avoid excessive filling causing damage to the seals).

　　电气与操控系统保养需谨慎。擦拭操作手柄、仪表盘表面的灰尘，检查按钮、开关是否灵敏（如急停按钮、前进后退操控杆），确保指示灯显示正常（若有故障灯常亮，需记录代码并联系技术人员排查）。清理蓄电池接线柱的氧化物（用干布蘸小苏打水擦拭，再涂抹凡士林防腐蚀），检查电解液液位（若为可维护电池，液位应高于极板 10-15 毫米，不足时补充蒸馏水）。

　　Caution should be exercised in the maintenance of electrical and control systems. Wipe the dust off the operation handle and dashboard surface, check whether the buttons and switches are sensitive (such as emergency stop button, forward and backward control lever), and ensure that the indicator lights are displayed normally (if there is a fault light that is constantly on, record the code and contact technical personnel for troubleshooting). Clean the oxide on the battery terminals (wipe with a dry cloth dipped in baking soda water, then apply Vaseline for corrosion prevention), check the electrolyte level (if it is a maintainable battery, the level should be 10-15 millimeters higher than the electrode plate, and add distilled water if it is insufficient).
