Connect the emergency drive hose during loading, relying on the power of other mixing trucks. Drive the mixing drum to rotate and discharge the concrete. However, if the reducer malfunctions simultaneously, this method cannot be used. The specific operation steps are as follows:

1，準備好一根緊急驅動軟管，卸下接管和接頭蓋；

1. Prepare an emergency drive hose and remove the connecting pipe and joint cover;

2，故障車（被驅動車）的操作：將故障混凝土攪拌車的發動機熄火；將緊固螺母朝左旋松；再將旋鈕朝右旋轉，直到不能再旋為止；將高壓軟管從馬達接頭處卸下；

2. Operation of the faulty vehicle (driven vehicle): turn off the engine of the faulty Concrete mixer; Loosen the fastening nut to the left; Rotate the knob to the right again until it can no longer be turned; Remove the high-pressure hose from the motor connector;

3，救援車（驅動車）的操作：將操作手柄于空檔位置；將發動機熄火；將高壓軟管從高壓油管處卸下；將緊急驅動軟管接到高壓油管上；用緊急驅動軟管上的接頭蓋將驅動車的高壓軟管蓋起，以防漏油。啟動救援車的發動機。將救援車的操作手柄撥“出料”位置，使故障車內的混凝土排出。緊急驅動完畢后，使兩車各自恢復原狀。

3. Operation of rescue vehicle (drive vehicle): Set the operating handle to the neutral position; Turn off the engine; Remove the high-pressure hose from the high-pressure oil pipe; Connect the emergency drive hose to the high-pressure oil pipe; Cover the high-pressure hose of the driving vehicle with the connector cover on the emergency drive hose to prevent oil leakage. Start the engine of the rescue vehicle. Move the operating handle of the rescue vehicle to the "discharge" position to discharge the concrete inside the faulty vehicle. After the emergency drive is completed, restore each vehicle to its original state.

4，減速機損壞。如在工作中出現減速機突然損壞，需將攪拌筒內的混凝土排出，以防出現凝固現象；其次再更換減速機，也可聯系生產廠家。

4. The gearbox is damaged. If there is sudden damage to the gearbox during work, it is necessary to first discharge the concrete from the mixing drum to prevent solidification; Secondly, to replace the gearbox, you can also contact the manufacturer.

5，柱塞泵發生故障。非裝載時換上新的柱塞泵，使拌筒恢復正常運轉。

5. The plunger pump has malfunctioned. Replace with a new plunger pump during non loading to restore normal operation of the mixing drum.
