Exposure time in sunlight is too long.

Solution：Return to normal after a period of time in the dark.

About 500 cycles may cause battery capacity attenuation, and the battery life depends on road conditions and weather. Due to weather reasons in winter, the charge and discharge function of lithium batteries will be weakened, and the battery life will be shorter.

If the taillight is not on, first check whether the taillight cable is connected properly. If the connection is in good condition, there is a problem with the controller or the taillight itself, and the controller needs to be replaced.

1)If the handle of the car body does not respond when pressed to the end, it may be that non-zero start is set. In the case of boot, the sliding speed can reach 5km/h.

Exclude non-zero start, acceleration motor does not work, electric quantity display is normal, headlight, brake light is normal, preliminary judgment is motor or controller problem, need to be replaced or motor.

1)First start up → back and forth pinch power brake handle → feel the reset elasticity → elasticity is normal, the taillight is still on → and can accelerate → replace power brake handle.

First start up → back and forth pinch power brake handle → feel the reset elasticity → elastic normal, taillight still bright → open the battery case → find the power brake handle terminal and unplug, → remove the terminal after the brake light → replace the controller.

1.Check whether the charger is faulty first. Plug in the charger and do not connect the car body. Observe whether the indicator light of the charger is on (normally it is green). If not, there is something wrong with the charger. You can also use a multimeter to measure the voltage of the charger. The normal voltage is 42V. If the voltage is not displayed, the charger will fail.

2. Check whether the charging port is loose and loose. Disconnect the power connected to the charger and plug in the car body.

3. If the charging port and charger are faulty, check whether the battery is faulty. A multimeter is available to measure the battery voltage.

Other controllers are faulty. Check whether the controller cable is connected. 9E: The thumb brake is faulty. Please check whether the brake is pressed. If not, please check whether the wiring between the brake and instrument is short or open.

thumb brake loss starts, please check whether the brake is pressed. Press release brake, brake reset.

the motor is missing phase, check whether the motor and controller line is connected, if there is a connection, please disconnect the connection line to measure whether the internal resistance between the motor three-phase money is reasonable, generally within 0.1Q-1Q, beyond the range, the motor needs to be replaced; Check whether the motor is too high and the motor temperature is too high. Wait for the motor to cool down to the working temperature. Check whether the connection between the normal detection line of the motor and the controller is short-circuitated.

The undervoltage is faulty. Check whether the battery cable is connected to the controller.

The controller is damaged and replaced.

please check whether the thumb accelerator is pressed down. If so, release the thumb accelerator and reset the accelerator. If not, please check whether the connection line between the thumb accelerator and the instrument is short-circuited or open. 

Check whether the cable between the motor and controller is connected. If not, connect the cable between the motor and controller.

1E: communication fault, solve: please check whether the brake taillight is on, if not, the controller power supply is not power supply, please replace the controller or instrument, if on, please check whether the connection line between the instrument and the controller is open.

You need to press the light button twice to turn on the headlight. If it still cannot be turned on, you need to replace the headlight.

If it cannot be folded or unfolded, you can consult the relevant video to learn from the after-sales service.

If the acceleration indicator does not rebound, check whether the indicator is stuck. If the acceleration indicator does not rebound, replace the indicator.

Do not remove the battery without permission. Otherwise, a short circuit may occur. After removing the battery pack, the internal circuit of the car body will be exposed. The internal circuit has a high voltage, and it is likely to receive electric shock when touching the internal circuit. To avoid danger, do not remove the battery pack by yourself. If the car body problems can contact Hengzhihe after-sales service for consultation, customers can according to customer service provide professional maintenance video to self-inspection and maintenance.

The diameter of the front and rear wheel is 8Inch.

For cruise control function, it is required to keep constant speed → press the open key 4 times continuously → hold for 3-5 seconds → release the handle → start cruise control.
