1、檢查保險開關：
1. Check the safety switch:
攪拌車是通過液壓傳動系統來驅動罐體的，液壓油散熱系統中最容易出現故障的就是保險開關，因此在故障發生后，最好第一時間檢查保險開關。
Mixer is driven by hydraulic transmission system, the most prone to failure in the hydraulic oil cooling system is the safety switch, so after the failure, it is best to check the safety switch at the first time.
2、檢查驅動風扇：
2. Check the drive fan:
電機是整個散熱系統中最為關鍵的部件，散熱效果的好與壞，和電機的轉速及運行的平穩狀態有著直接的關系，它由連接車輛電瓶的電控盒直接供電，用電力驅動電機高速運轉，來帶走熱交換器當中的額熱量，給液壓油降溫。
The motor is the most critical component in the whole heat dissipation system. The good or bad heat dissipation effect is directly related to the speed of the motor and the stable running state. It is directly powered by the electric control box connected to the vehicle battery, and uses the electric power to drive the motor to run at high speed to take away the amount of heat from the heat exchanger and cool the hydraulic oil.
3、檢查熱交換器：

3. Check the heat exchanger:
攪拌車利用液壓油散熱器來進行降溫。熱交換器上裝有電機驅動風扇進行散熱，讓液壓油正常工作，上面的機械式指針通過檢測管路當中的負壓，如果出現讀數證明液壓油濾清器可能出現堵塞，剛開始出現的時候只需要拔掉上面的橡膠指針歸零，如果后面還出現讀書且拔掉橡膠塞之后還解決不了的話，就需要更換液壓油濾芯了。
Mixer truck uses hydraulic oil radiator to cool down. The heat exchanger is equipped with a motor-driven fan to dissipate heat, so that the hydraulic oil can work normally. The mechanical pointer on the top detects the negative pressure in the pipeline. If the reading indicates that the hydraulic oil filter may be blocked, just pull out the rubber pointer to zero at the beginning. If there is still a reading behind and the problem can not be solved after pulling out the rubber plug, The hydraulic oil filter element needs to be replaced.
4、檢查熱傳感器：
4. Check the thermal sensor:
溫度傳感器位于熱交換器的進油管上，它的作用就是檢測液壓油的溫度，攪拌車散熱系統發生故障后，如果確認不是保險的問題，那就檢查溫度傳感器。
The temperature sensor is located on the oil inlet pipe of the heat exchanger. Its function is to detect the temperature of the hydraulic oil. After the heat dissipation system of the mixer fails, if it is confirmed that it is not the insurance problem, check the temperature sensor.
5、檢查散熱器控制盒：
5. Check the radiator control box:
