Maintenance Information
Overview
The charger will be thermal in charging. It should be subject to good ventilation and radiation. The
battery and charger must not be covered. They must not be close to flammable or explosive objects in
charging to avoid the explosion or fire that may even cause personal injuries.
There is a high-voltage current in the charger when the charging is made. The charger is prohibited
strictly from being touched or opened in order to prevent electric shock.
The charging should be made indoor and should not be made at an open site in order to prevent the
electric shorting or firing due to rain and other factors. The charging is prohibited strictly from being made
in a rainy, exposure or high-temperature environment or close to fire sources.
The dedicated charger made by an original manufacturer and a stable 110-240V AC power supply
should be used in charging. The polarity of the charger output connector must be consistent with that of
the battery output connector, otherwise the charger and battery will be damaged.
Note:
The power supply lock and air switch should be turned off before removal of electric elements.
The terminal or connector removal or connection may lead to damages of some units when the power
supply lock is opened and there is a current.
The battery used for this model is a lithium battery.
Remove the battery from the scooter for scooter storage for a long time. Charge the battery to
approximately 50% of its capacity and store it at a room temperature. Perform periodical charging of the
battery. The long-term storage in lack of the electricity is strictly prohibited.
The battery should be fully charged for use after long-term storage.
The original battery for this model must be charged with the dedicated charger that accompanies with
the scooter (the scooter charging with a non-original charger will cause irrecoverable damages to the
battery). Charging with a non-original charger may lead to the circuit or battery failure.
The scooter charging is prohibited strictly from being made immediately after scooter stop. The charging
should be made when the battery surface has been naturally cooled down (it is recommended to make
charging after 30 minutes).
Stop charging immediately if the battery has not been fully charged for more than 24 hours and the red
lamp does not turn to green, and then contact the after-sale service for inspection of the charger and
battery.
