What are the maintenance taboos for small concrete mixer trucks?

For many customers, the maintenance methods of small concrete mixer trucks are commonplace. They know how to repair which parts and which parts cannot be repaired in this way. However, some new customers should be vigilant. Once the mixing tank fails, it should be repaired as soon as possible. However, some customers are not good at repairing mixing tanks and often make wrong operations. This will not only fail to repair the mixing tank, but will make the problem worse. Let me focus on the maintenance taboos of small concrete mixer trucks.
1. The accelerator cannot be stepped on when the electronic injection vehicle is started. Once the accelerator is stepped on, the engine of the concrete mixer truck will start poorly.
2. The tire bolt nuts of the concrete mixer truck cannot be oiled. Many drivers believe that applying lubricating oil to the tire bolt nuts can prevent the bolts and nuts from rusting. In fact, this practice is very dangerous because it will bring great safety hazards to the driving of the mixer truck. Bolts and nuts have self-locking characteristics after tightening, and lubricating oil will reduce the self-locking coefficient. During the operation of the mixing tank, once the bolts and nuts are loose, a safety accident will occur.
3. Do not directly wash the body of the small concrete mixing tank truck with water. The internal structure of the mixing tank body is relatively complex, with many grooves and through-holes. Once it is washed with water, the water deposited in the body is not easy to dry, which can easily cause the parts to rust.
