1. After working for 50 hours for the first time, tighten the U-bolts of the front desk, the connecting bolts between the front desk and the base of the reducer, the connecting bolts between the flange of the reducer and the mixing drum, the fastening bolts between the supporting wheel and the frame, and the locking nuts of the supporting wheel; After that, it will be checked once a month.

2、各紧固螺栓在出厂前都经过严格检验，均达到要求的紧固力矩，对于因使用而发生的松动，要及时紧固，恢复其规定力矩，严重损坏的要及时更换。

2. All the fastening bolts have been strictly inspected before leaving the factory, and all of them have reached the required tightening torque. For looseness due to use, they should be tightened in time, and the specified torque should be restored. If they are seriously damaged, they should be replaced in time.

3、每次在车辆发动之前，检查液压油冷却器和减速机的油位，保证油位指示在目视范围内；液压系统应经常保持清洁和密封，以免尘粒和水份等污染系统液压油，造成系统不能正常工作或损坏。

3. Every time before the vehicle starts, check the oil level of the hydraulic oil cooler and reducer to ensure that the oil level indication is within the visual range; The hydraulic system should always be kept clean and sealed to prevent dust particles and water from polluting the hydraulic oil of the system and causing the system not to work normally or damage.

4、每天行车前检查托轮与滚道的结合面润滑油是否干涩，应及时补充，保持良好的润滑效果。及时检查散热器的风扇和温控开关的性能，保证其正常工作,油温一般在60℃左右时风扇会自动打开。

4. Every day before driving, check whether the lubricating oil on the joint surface of the roller and the raceway is dry, and replenish it in time to maintain a good lubricating effect. Check the performance of the radiator fan and temperature control switch in time to ensure its normal operation. When the oil temperature is about 60 ℃, the fan will turn on automatically.

5、至少每月打开一次托轮护罩，清理里面的污物；通过托轮上的油嘴，向托轮内注入润滑油脂。保证传动轴至少每月润滑一次。

5. Open the supporting wheel shield at least once a month to clean the dirt inside; The lubricating grease is injected into the supporting roller through the oil nozzle on the supporting roller. Ensure that the transmission shaft is lubricated at least once a month.

6、经常性检查管路及液压设备的紧固螺栓是否有松动，保障设备的安全，必要时更换螺栓。至少每隔6个月检查液压泵、液压马达及油路的密封性能。

6. Regularly check whether the fastening bolts of pipelines and hydraulic equipment are loose, ensure the safety of equipment, and replace the bolts when necessary. Check the sealing performance of hydraulic pump, hydraulic motor and oil circuit at least every 6 months.

7、注意观察散热器上的真空表指示，当指针位于红色区域时，应及时更换滤芯，对于使用一年以上的滤芯，即使指针不在红色区域，也应该更换；要使用同一生产厂家的产品。

7. Pay attention to the indication of the vacuum gauge on the radiator. When the pointer is in the red area, the filter element should be replaced in time. For the filter element that has been used for more than one year, even if the pointer is not in the red area, it should be replaced; Use products from the same manufacturer.

8、液压油及齿轮油必须定期更换（此条特别关键，做不好会造成液压件故障、闷罐），运行100工作小时必须更换，以后每1000工作小时（但至少每年）必须更换一次，滤芯应该同时更换（对于一体化的散热器，无压力表指示，应遵循本条更换滤芯）。

8. The hydraulic oil and gear oil must be replaced regularly (this is particularly critical, if it is not done well, it will cause hydraulic parts failure and tank tightness). It must be replaced after 100 working hours of the first operation, and every 1000 working hours (but at least once a year) thereafter. The filter element should be replaced at the same time (for the integrated radiator, if there is no pressure gauge indication, the filter element should be replaced according to this article).
