Electric-vehicle maintenance (5) electrical control structure is complex, the user should not disassemble, repair. Such as local charging voltage instability, easy to make the charger fuse blows, use of an AC voltage regulator. (6) when the bike feel heavier backwards and forwards will be implemented within the hub slight friction sound are normal. (7) should not be overloaded riding, should not be placed too heavy with goods and people, in order to avoid damage to the battery and motor. Electric tricycle Maintenance: electrical control parts of the complex structure, the user should not disassemble, repair. Such as local charging voltage instability, easy to make the charger fuse blows, use of an AC voltage regulator. Bike feel heavier when backwards, and the implementation within the hub will be slightly ahead of friction sound are normal. Should not overload electric tricycle riding, should not be placed too heavy with goods and people, in order to avoid damage to the battery and motor. Should be checked before riding the battery compartment is securely locked, the display panel of the lamps are normal. When driving in rain puddles, the water no deeper than normal driving under electric wheel hub circumstances, such as with surface water deeper than electric wheel hub, will likely make electric wheel failure caused by water seepage. Vehicle should be avoided on the air is humid, high temperature and corrosive gases, so as not to make the paint surface plating chemical corrosion of metal parts. Avoid prolonged exposure to the sun and rain vehicle new electric tricycle, so as not to damage components within the controller, causing malfunctioning electric tricycle Junan, accident. Bicycle maintenance bicycle lubrication is an important part of electric tricycle accessories, according to usage, coping front axle, rear axle, axis, flywheel, fork, shock absorbers and other components of the pivot point once every six months to a year to scrub and lubrication (Recommended molybdenum disulfide grease). The hub electric drive components have been coated with a special lubricant, users do not have to scrub their own lubrication. An abnormality is detected can be made to carry out special maintenance company maintenance. Note the use of electric vehicles: 9, various parts of the switch is sensitive and reliable. 10, steady speed, and reliability. Slowly turn the handle speed, the motor should be a smooth start, acceleration, after releasing the handle, the handle can be quickly reset, the motor even slow down. 11, power brakes fast and reliable. Rotational speed control lever, the motor run, pinch the brake after the brake, the motor can instantly power, if power display, you can see the display back to zero. 12, the battery easy disassembly. Lead-acid battery weight is generally about 13.5kg, due to dismantling every day, so the battery location must be suited to your body.
