Because electric vehicles in the process of driving, electric vehicles will produce varying degrees of looseness and mechanical     wear, if not regular maintenance,will lead to the decline of power, economy, reliability, safety of electric vehicles, but  also shorten the service life of electric vehicles, so the driver of electric vehicles must     carry out the correct regular maintenance of electric vehicles, to ensure the best performance of electric vehicles. Through the correct  regular maintenance,we can remove obstacles in time, extend the  service life of electric vehicles, reduce maintenance costs, and achieve the purpose of safe driving of electric vehicles. Electric vehicle maintenance has the following requirements:

①Keep the motor differential clean, no oil leakage, good acceleration performance and dynamic performance, no abnormal   sound.

②Ensure that the speed regulating handle can rotate freely without sticking.

③Ensure that the operation of the brake handle is light and     flexible, and the braking effect meets the requirements. When the     brake is released, the brake shoes reset automatically and the sliding   performance of the friction free motor      is good.

④The front and rear shock absorbers are stable and reliable, the tire pressure is normal, and the electrical parts of each part work normally.

⑤There is no looseness in the connecting fasteners of the  whole car,and  the appearance of  the  whole car is clean and tidy.

The more detailed maintenance operation requirements are as shown in the following figure:
