warning

• The tire (front wheel pressure: 280 KPa rear wheel pressure: 280 KPa) should be regularly checked the tyre pressure and adjusted;
• The tyre pressure can only be checked when the tire is cooled. Should often check whether there are puncture holes on the tyre, especially if the tyre leakage phenomenon should be immediately repaired.
• Check the tyre surface for scratches, embedded nails or other sharp objects. Check the rim for indentation, dents or deformation.
• When the tyre is worn to the tread wear limit mark。

warning：

• If the tyre pressure is not the standard, it will make the tyre surface by too much wear and may lead to an accident. Too low tyre pressure will cause the tyre to slip around or take off the wheel rim; The use of very worn tires is very dangerous, which will affect the adhesion between the tire and the road surface, resulting in driving difficulties and even accidents;

Maintenance and maintenance

The maintenance period is based on the mileage, which is the guiding basis for the implementation of regular maintenance and lubrication. If it is driving at high speed for a long time under harsh conditions, the number of maintenance must be increased. If the electric vehicle has been overhauled or collided, it must carefully check the main parts of the electric vehicle and repair or replace the misplaced or damaged parts to ensure the safety of the vehicle.

Maintenance method (Figure 18)

• The rear axle gear oil should be replaced when the vehicle travels every 2,000 km.
• Open bolt 1 out of gear oil and tighten bolt 1, open bolt 2 to inject gear oil (85W / 90GL-4) about 150 mL, and then tighten bolt 2 after refuelling.

Note: To ensure the safety and reliability of electric vehicles, electric vehicles are not allowed to be modified. When repair or maintenance, replace our original parts or similar parts of equal quality. If other poor quality parts are used, it will affect the performance of the electric vehicles and the operation of the function；

Warning: To ensure the safety of personnel, regardless of any program maintenance work, must first turn off the power supply, park the car on flat and hard ground stable；

Attention

1. If the car is parked for more than a month or stopped during the winter, it is necessary to do a good job of maintenance to prevent tyres and batteries Such as deterioration, aging and corrosion;
2. Unless the driver or the owner has a full set of repair tools and maintenance materials and is a qualified mechanical professional, professionals should be asked to be responsible for maintenance and repair; from the safety perspective, we advocate that these items should be responsible for maintenance or repair by the maintenance department;
3. If the vehicle is often driven in particularly wet or dusty areas, it is best to shorten the specified maintenance period;
4. If often driving on uneven road surfaces, to ensure the performance of the vehicle, please timely maintenance；

• When the vehicle is not in use for a long time, please remove the battery and store it in a cool, ventilated and dry place.
• When the head of the battery pile is corroded, remove the battery and clean it.(With boiling water can be washed well.)

Note: when removing the battery, close the ignition switch, and then remove the negative electrode first, install the positive electrode first and then install the negative electrode, do not install the positive and negative electrode wrong.

Maintenance and maintenance of the hydraulic brake (please send it to the designated repair shop for maintenance) Figure 17

• When the vehicle travels every 2000 kilometres, the foot brake top rod nut for tightening, and correction;
• Check the hydraulic oil of the refuelling pot and the oil storage amount of the refuelling pot should not be less than 2 / 3 of the oil can;

Vehicle Storage

Keep in storage

• To store electric vehicles for a long time (for example in winter), several steps need to be taken to prevent any failure or damage caused by long-term unused electric vehicles. In addition, before preparing for storage, some maintenance work needs to be carried out, otherwise it is often forgotten when using the electric vehicle again.
• Replace the rear axle gear oil. Cover the vehicle cover. When using the electric vehicle from the storage: Take the vehicle cover and clean the vehicle. If the storage time has been more than 4 months, the axle gear oil should be replaced.
• Charge immediately if necessary and then pack the battery. Before driving, all parts should be checked, and first test drive the electric vehicle for some time in unbusy traffic areas to ensure safety.

Vehicle identification

Vehicle nameplate (Figure 15) shows: The vehicle nameplate bracelet connects to the right side of the driver’s bucket. It contains the frame number, model, brand, vehicle quality, motor model, maximum output power, rated voltage, loading quality, production date and other information.
