When the electric cargo tricycle needs to effectively adjust the height of its saddle during operation, it should be noted that the saddle pipe safety line should not be exposed outside the middle tube of the frame. When adjusting the height of the handlebar, be careful not to expose the riser safety line outside the front fork lock. Check whether the brake power-off device is in good condition, support the bracket, open the electric door, rotate the right-turn handle, start the motor, and then gently hold the left brake lever. The motor should be able to power off quickly and gradually stop rotating. At this time, if the motor cannot be powered off, stop the drive and ask the professional to repair it before use.
Before the electric cargo tricycle is driving, it should effectively check the electrical plug of the battery box, whether the polar seat is shaken, whether the electric door lock is flexible, whether the battery box is locked, whether the speaker and the light button are effective, and whether the light bulb is good. The height adjustment of the saddle of the electric tricycle is based on the ground of the rider's feet to ensure safety.
Maintenance of electric cargo tricycle
Loose output plug of the charger and oxidation of the contact surface will cause the charging plug to heat up. If the heating time is too long, the charging plug will be short-circuited, which will directly damage the charger and cause unnecessary loss. Therefore, when the above situation is found, the oxide should be removed or the connector replaced.
If the temperature is too high, the internal pressure of the battery will increase and the battery pressure limiting valve will be forced to open automatically. The direct consequence is to increase the water loss of the battery. The excessive water loss of the battery will inevitably lead to the decrease of battery activity, accelerate the softening of the plate, and charge the case. Body heat, the shell caused by fatal damage such as drums and deformation.
