(1) Before riding, check whether the battery compartment is locked securely and whether the lights on the display panel are displayed normally. 

(2) When driving on a waterlogged road on a rainy day, the depth of water does not exceed the centre of the electric wheel under normal driving conditions; if the depth of water on the driving road exceeds the centre of the electric wheel, it may cause the electric wheel to seep and cause malfunction. 

(3) Avoid placing the vehicle in places with humid air, high temperature and corrosive gases to avoid chemical corrosion of the plated paint surface of the metal parts. 

(4) Avoid exposing the whole vehicle to the sun and rain for a long time, so as not to damage the components in the controller and cause malfunctioning of the operation and accidents. 

(5) The structure of the electrical control part is complicated, so the user should not disassemble and repair it without permission. If the local charging voltage is unstable, it is easy to make the charger fuse blow, so it is recommended to use AC voltage stabilizer.
