For your safety, please refer to the User Manual to replace the blades.

A solid red light effect indicates that there is no connection between the charging station and the mower. If either the charging station or the mower is not powered on or plugged in, the other one will flash a solid red light. Interference in the environment may also cause short-term communication abnormalities, and a red light will appear, which will usually go off by itself and will not affect your use.

If the power supply of the mower and the charging station is normal, but the solid red light still appears frequently, please contact the after-sales service.

Usually, the battery ages after a long period of use, and the working hour gets shortened. You can contact your dealer and have the battery replaced to resume the previous working hour. Besides, the working hour of Navimow can get shortened when running on a lawn with complex conditions, such as long grass, complicated layout, etc. In this case, to reach the ideal working hour, you can mow the long grass with other mowing tools first and if possible, adjust the garden layout to a simpler one.

When pushed into the charging station, the charging strip on the mower will firmly contact the contact strip on the charging station. Therefore the battery can get electricity input from the charging station until the battery is fully charged.
