Maintenance of hydraulic cylinder of loader accessories, i.e. maintenance of hydraulic medium and hydraulic cylinder block. The advantages of hydraulic transmission are simple structure, stable quality, high mechanical efficiency and easy automation. How to make the hydraulic machinery run better, correctly select the hydraulic oil according to the system pressure, running speed, working oil volume and ambient temperature, and correctly use and maintain the Jinan loader is the key to the work. When maintaining the hydraulic cylinder, be sure to prevent contamination and impurities from mixing into the hydraulic oil:

1、油缸在使用过程中应定期更换液压油，清洗系统滤网，保证清洁度，延长使用寿命。

1. During the use of the oil cylinder, the hydraulic oil shall be replaced regularly, and the system filter screen shall be cleaned to ensure cleanliness and prolong the service life.

2、油缸在每次使用时，要进行全伸全缩的试运转5个行程然后再带载运行。这样做可以排尽系统中的空气，预热各系统，能够避免系统中存在空气或水，在油缸缸体造成气体爆炸（或焦烧）现象，这样会损害密封件，造成油缸内泄等故障。

2. When the oil cylinder is used each time, the test run of full extension and full contraction shall be carried out for 5 strokes, and then the loaded operation shall be carried out. This can exhaust the air in the system and preheat each system, so as to avoid the existence of air or water in the system and cause gas explosion (or scorching) in the cylinder block, which will damage the seals and cause internal leakage of the cylinder.

3、控制好系统温度，油温过高会减少密封件的使用寿命，长期油温高使密封件发生变形，甚完全失效。

3. Control the system temperature well. If the oil temperature is too high, the service life of the seal will be reduced. Long term high oil temperature will deform the seal or even completely fail.

4、防护好活塞杆外表面，防止磕碰和划伤对密封件的损伤，经常清理油缸动密封防尘圈部位和裸露的活塞杆上的泥沙，防止粘在活塞杆表面上的不易清理的污物进入油缸内部损伤活塞、缸筒或密封件。

4. Protect the outer surface of the piston rod to prevent the damage to the seal caused by collision and scratch. Regularly clean the sediment on the dynamic seal dust ring of the oil cylinder and the exposed piston rod to prevent the dirt on the surface of the piston rod from entering the oil cylinder and damaging the piston, cylinder barrel or seal.

5、经常检查各螺纹、螺栓等连接部位，发现松动立即紧固好。

5. Regularly check the connecting parts such as threads and bolts, and fasten them immediately if they are loose.

6、经常润滑联接部位，防止无油状态下锈蚀或非正常磨。

6. Frequently lubricate the connecting parts to prevent corrosion or abnormal wear without oil.

因为受环境温度的影响，小型装载时机面对很多艰难，如整机的“心脏”部件柴油机，因为温度的增加使光滑油的粘度下降，光滑下降，并且使动力下降，其内部机件通常也简单发生磨损，这是对比多见的毛病。因而在搞好小型装载机夏日保护技能的时分更要细心对柴油机进行必要的全部的保护。

Due to the influence of ambient temperature, the small loading time is faced with many difficulties. For example, the "heart" component of the whole machine, diesel engine, because the increase of temperature reduces the viscosity and smoothness of smooth oil, and reduces the power. Its internal parts are usually simply worn, which is a common problem. Therefore, when doing a good job in the summer protection skills of small loaders, we should carefully protect the diesel engine.

为了确保小型装载机的冷却体系效能良好，在进入夏日曾经，应对冷却体系的各个部件进行完全的整理、紧固和光滑，尽可能的整理冷却体系水垢包含散热器内的水垢整理洁净），以进步散热效能，坚持冷却体系冷却水的循环。

In order to ensure the good efficiency of the cooling system of the small loader, all components of the cooling system should be completely sorted, fastened and smooth in summer, and the scale of the cooling system (including the scale in the radiator) should be sorted as much as possible, so as to improve the heat dissipation efficiency and adhere to the circulation of cooling water in the cooling system.

查看水泵一电扇传动皮带，皮带经长期使用后，皮带会发生疲惫、变形，下降冷却作用。皮带更换时，要留意类型和长度，并准确调整其松紧度。

Check the drive belt of water pump and electric fan. After long-term use, the belt will be tired and deformed, reducing the cooling effect. When replacing the belt, pay attention to the type and length, and accurately adjust its tightness.

查看水箱衔接胶管，水箱的胶管的耐油性对比差，简单早期损坏，然后影响供水量，导致发动机温度升过高。查看有决裂和漏水表象，要及时排除。一起要坚持足量的冷却水，发现缺乏要及时增加。

Check the connecting hose of the water tank. The hose of the water tank has poor oil resistance, simple early damage, and then affects the water supply, resulting in excessive engine temperature rise. Check whether there are cracks and water leaks, and eliminate them in time. Together, we should adhere to sufficient cooling water and increase it in time in case of lack.

为确保整机的正确使用，要时间留意水温表的读数，到达90°以上时有必要采纳办法。可选择就近的阴凉处泊车并以怠速降温，留意不要立刻熄火，以避免发动机内部过热而形成拉缸等事故。待温度降下来后，还应查看电扇皮带的张力状况。

In order to ensure the correct use of the whole machine, pay attention to the reading of the water temperature gauge for a long time. When it reaches more than 90 °, it is necessary to adopt measures. You can park in the nearest shade and cool down at idle speed. Be careful not to turn off the engine immediately, so as to avoid accidents such as cylinder pulling caused by overheating inside the engine. After the temperature drops, check the tension of the fan belt.

装载机适用在中小修建施工，工地需求很多的混泥土。在配比混泥土时，通常修建施工公司所需的原材料（石子，沙子及水泥）大都是用人手推车从料场转移拌和机中拌和混合，小型装载机适用在中小修建施工，工地需求很多的混泥土。在配比混泥土时，通常修建施工公司所需的原材料（石子，沙子及水泥）大都是用人手推车从料场转移拌和机中拌和混合，这种依托人工上料，人工转移的办法，劳动强度大出产功率低，已不合适现代出产请求：而大型装载机又不合适用，为此将农用拖拉机改装为实用性小型装载机，处理这一疑问。

Loaders are suitable for small and medium-sized construction, and the construction site needs a lot of concrete. When proportioning concrete, most of the raw materials (stones, sand and cement) required by the construction company are transferred from the stockyard to the mixer by man-made trolleys. Small loaders are suitable for small and medium-sized construction, and the construction site needs a lot of concrete. When proportioning concrete, most of the raw materials (stones, sand and cement) required by the construction company are transferred from the stock yard to the mixer by man-made trolleys. This method of relying on manual feeding and manual transfer has high labor intensity and low production power, which is not suitable for modern production requirements; and large loaders are not suitable for use, Therefore, the agricultural tractor is refitted into a practical small loader to deal with this problem.
