1 Routine Inspection

During normal use, the following items shall be checked for routine inspection.

1)Whether the wiring part or the mounting bolt is loose;

2)Whether the insulation layer of the conductor is damaged or not;

3)Whether the cooling pipe leaks or not, if so, it shall be reconnected and fastened;

4)Whether the electrical parameters meet the requirements;

5)Check the fasteners for each location.

2 Periodic Inspection

1)Measure the motor insulation resistance, and it should be larger than 200 MΩ;

2)Check if there is any abnormal sound during bearing rotation;

3)Check whether the joint is loose.

The inspection items listed above shall be carried out every six months except specially designated inspection items.

4)The use and maintenance of the gear box shall be carried out according to the requirements of the use and maintenance of commercial vehicles, which is generally divided into three levels of technical maintenance;

5)The gear box lubricating oil should be regularly checked and replaced (or supplemented);

6)Fill each grease fitting with 2 # lithium-based grease for every 2000km;

7)Check the fastening condition of the brake plate, the looseness condition of the hub bearing and the wear condition of the brake pad for every 8000-10000km. If the wear condition of the brake pad exceeds the limit pit, the brake pad must be replaced immediately.

3 Check and replacement of gear oil in gear box

The vehicle should be parked on the level ground while filling oil and inspecting the oil level.

1)Keep refueling until the specified amount of oil!

Insufficient or excessive oil will lead to overheating, which shall cause the damage to the transmission parts.

2)Check oil level regularly!

Check the oil level position of the gear box at least once a month or every 10,000 km. The inspection shall be carried out when the lubricating oil is cooled to the ambient temperature and the oil level is stable.

3)Oil change time

(1)The first oil change shall be carried out after driving for 5000 km or 125 hours

(2)The subsequent oil change should be carried out according to the use of the vehicle which has a maximum of driving distance for 100,000km, or oils should be changed at least once a year.

(3)For vehicles that have been used regularly under high temperature (above +30°C) conditions, the vehicle can travel up to 40,000 kilometers or for 1,000 hours, but the oil should be changed at least once a year.
