Jianghuai Ruifeng s7 Major Maintenance Project

Winds7 maintenance is carried out every 40,000 kilometers. 20,000 km maintenance, replacement of oil, machine filter, air filter and air filter element, and some routine inspections, as follows:

① Air filter

Proper installation of air filter can reduce the wear of cylinder, piston and piston ring. Usually, the air filter element is cleaned every 5000 km, and the air filter must be replaced every 1000 km.

② Oil filter

Proper installation of the oil filter can prevent impurities from mixing into the oil during the use of the internal combustion engine, and prevent the moving parts from being worn and the oil from being blocked. When replacing lubricating oil, the oil filter must be replaced at the same time, otherwise the quality of lubricating oil will be affected. The cycle of changing oil and oil filter is generally 5000 kilometers.

③ Fuel filter

Proper installation of fuel filter can prevent cylinder wear caused by gasoline mixed with impurities and moisture during storage, transportation and filling. In order to ensure the good operation of the engine, the replacement cycle of the fuel filter is generally 20,000 kilometers or 1 year. Special suggestion: the maintenance of "three filters" must be carried out by professional maintenance personnel.

The major maintenance cost of Ruifeng s7 is generally more than 2,000 yuan, mainly including oil replacement, oil filter, gasoline filter, air filter, throttle valve cleaning and matching, brake oil, antifreeze, gearbox oil, spark plug, booster oil, tire transposition and dynamic balance, oil circuit cleaning and engine cleaning. That's basically it. If maintenance is performed,
