1. For the first 50 hours of operation, tighten the front desk U-bolt, the connecting bolt between the front desk and the reducer base, the connecting bolt between the reducer flange and the mixing drum, the fastening bolt between the supporting wheel and the frame and the locking nut of the supporting wheel; After that, check it regularly once a month.

2、各緊固螺栓在出廠前都經(jīng)過嚴(yán)格檢驗(yàn)，均達(dá)到要求的緊固力矩，對于因使用而發(fā)生的松動，要及時(shí)緊固，恢復(fù)其規(guī)定力矩，嚴(yán)重?fù)p壞的要及時(shí)更換。

2. All fastening bolts are strictly inspected before leaving the factory and meet the required tightening torque. For looseness due to use, they shall be tightened in time to restore the specified torque, and those seriously damaged shall be replaced in time.

3、每次在車輛發(fā)動之前，檢查液壓油冷卻器和減速機(jī)的油位，保證油位指示在目視范圍內(nèi)；液壓系統(tǒng)應(yīng)經(jīng)常保持清潔和密封，以免塵粒和水份等污染系統(tǒng)液壓油，造成系統(tǒng)不能正常工作或損壞。

3. Before starting the vehicle every time, check the oil level of hydraulic oil cooler and reducer to ensure that the oil level indication is within the visual range; The hydraulic system shall be kept clean and sealed frequently to prevent dust particles and water from polluting the hydraulic oil of the system, resulting in the failure or damage of the system.

4、每天行車前檢查托輪與滾道的結(jié)合面潤滑油是否干澀，應(yīng)及時(shí)補(bǔ)充，保持良好的潤滑效果。及時(shí)檢查散熱器的風(fēng)扇和溫控開關(guān)的性能，保證其正常工作,油溫一般在60℃左右時(shí)風(fēng)扇會自動打開。

4. Before driving every day, check whether the lubricating oil on the joint surface of supporting wheel and raceway is dry, and supplement it in time to maintain good lubrication effect. Timely check the performance of the fan and temperature control switch of the radiator to ensure their normal operation. Generally, the fan will turn on automatically when the oil temperature is about 60 ℃.

5、少每月打開一次托輪護(hù)罩，清理里面的污物；通過托輪上的油嘴，向托輪內(nèi)注入潤滑油脂。保證傳動軸少每月潤滑一次。

5. Open the idler shield at least once a month to clean the dirt inside; Inject lubricating grease into the supporting roller through the nozzle on the supporting roller. Ensure that the drive shaft is lubricated at least once a month.

6、經(jīng)常性檢查管路及液壓設(shè)備的緊固螺栓是否有松動，保障設(shè)備的，必要時(shí)更換螺栓。少每隔6個(gè)月檢查液壓泵、液壓馬達(dá)及油路的密封性能。

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

7、注意觀察散熱器上的真空表指示，當(dāng)指針位于紅色區(qū)域時(shí)，應(yīng)及時(shí)更換濾芯，對于使用一年以上的濾芯，即使指針不在紅色區(qū)域，也應(yīng)該更換；要使用同一生產(chǎn)廠家的產(chǎn)品。

7. Observe the indication of the vacuum gauge on the radiator. When the pointer is in the red area, replace the filter element 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, replace it; Use products from the same manufacturer.

8、液壓油及齒輪油必須定期更換（此條特別關(guān)鍵，做不好會造成液壓件故障、悶罐），運(yùn)行100工作小時(shí)必須更換，以后每1000工作小時(shí)（但少每年）必須更換一次，濾芯應(yīng)該同時(shí)更換（對于一體化的散熱器，無壓力表指示，應(yīng)遵循本條更換濾芯）。

8. The hydraulic oil and gear oil must be replaced regularly (this article is particularly critical, and failure to do it well will cause hydraulic part failure and tank tightness). It must be replaced after the first 100 working hours, and then every 1000 working hours (but at least every year). The filter element should be replaced at the same time (for the integrated radiator, if there is no indication of pressure gauge, the filter element should be replaced according to this article).
