Transmission lubrication：

Do not use inferior lubricants, and do not mix lubricants of different brands!

When adding lubricant, the vehicle should be parked on a level road surface and lubricant should be added to the lower edge of the oil level hole.

Must use general vehicle lithium base lubricant conforming to GB5671-85 standard requirements.

Maintenance of the Reducer

Check the lubricant oil level when driving 3000Km. The oil level shall be at the lower edge of the oil level mouth, and add more lubricant if needed.

Change the lubricating oil in the transmission when driving 5000km, and change the oil every 60,000km after that.

Check the working condition of each bearing of the reducer at 300,000km and replace it if necessary.

Maintenance of the vent plugs: vent plugs should be cleaned frequently to remove dirt and keep it clear.

Change of Lubricating Oil for Reducer

In the process of oil change, place a suitable container under the oil drain plug, remove the filling plug and the oil drain plug, discharge gear oil (it is easier to discharge when the temperature is high) and so on. After exhausting all the oil, install the oil drain plug (replace the sealing ring when necessary). Fill the new gear oil following the specified oil level. If the filling port is not easy to reach, use the hose for filling. After filling, install the filling plug (replace the sealing ring if necessary).

When install the oil plug, please make sure to gently screw the plug in by hand first, and then use the tool to tighten it to the specified torque. It is strictly prohibited tightening the oil plug directly using the tool or apply the tightening torque exceeding the specified torque.
