Use and Maintenance
1. Insert the car key into the power switch, clockwise open, at this time the power supply and po w er
display light on the instrument screen ison, indicating that the power supply is c onnec t ed.
2. Afterstarting, the right hand will rotate slowly the throttle backward, gradually accelerate, loose the
throttle can reduce the speed until the motor power supply is cut off.When driving, please drive o n non-
motorized roads at a low speed.
3. The vehicle has the function of brake power-offprotection. Whatever the left and right br ak e
handlebars, the motor power supply can be cut off to ensure the safety of driving.
4. After parking, if want the motor to be restarted, reset the speed control handle and then slo wly rotate
the speed control gradually .
Note for the use of motor and c ontr oller .
1. When driving against the wind or climbing, do not accelerate rapidly, but should accelerate e v enly and
gradually to avoid excessive load on the motor and b a tt er y .
2. In the rainy season, the vehicle should avoid from the center line of the rear wheel, to avoid the
motor and battery damp, burn the motor.
3. When driving, should avoid operate the speed control and brake at the same time, so as not to
overload the motor and damage to other p art s.
4. The vehicle is not adapt to uneven or steep road driving, if the vibration is large, will cause poor

9
contact with electrical parts, if to this road, please try to slow down as well.

10
! W arning:
1. Do not instantly accelerate the speed, to ensure the safety of driving, while protecting the
mo t or , bat te r y .
2. The vehicle with differential rear axle motor, the differential for gear combination needs gear oil
lubrication, usually called gearbox, in normal driving conditions should be changed gear oil every 3
months.
Precautions for useof b a tt er y
1. Technical f e a tur e:
At present, the commonly used battery is "sealed maintainable lead-acid battery" as the energ y
storage component of leisure vehicles, with large capacity, long life and good maintainability .
2. Battery is a c onsumable:
Battery is equivalent to the "fuel tank" in the car, isthe place to store energy, but it isdifferent from the "fuel
tank" lies in: its "volume" will decrease with the depth of use, in this sense,battery belongs to
consumables. And this "reduction" "decline" speed isdifferent, the choice of high quality battery, t he
correct use of battery, good car condition, especially the use of high efficiency motor will effec tiv ely delay
the decline of battery c apacity .
3. Correct useof the battery, pr ec autions:
! Always put the battery in a sufficient power state. Lead acid battery should be replenished in time,
which
isbeneficial to prolong the life of the battery. If the battery is not used for a long time, please be sure to keep
the battery in a state of sufficient power, and charge once a month, it is strictly prohibit ed to "lose power"
storage. ！Pay attention to check whether the temperature on the surface of the

11
battery box when charging the battery, and whether the charger indicator is changed to "orange"
and
"green". If it cannot be converted, please immediately cut offthe power supply and send the cha r ger and
the battery to the maintenance center for inspec tion.
! At low temperature (below 15℃) conditions, the battery is easy to decline by 20%~30%, and the
corresponding range will also be r educ ed.
! When replacing the internal battery of the battery pack, it isstrictly prohibited to mix the battery w it h different
performance parameters, otherwise the battery will cause damag e.
! Battery shall not contact the flame, heat source and alkaline substances, avoid direct sunlight
exposure, otherwise it will shorten the battery life.

12
!! After driving in summer, because the battery
temperature is high, it should not be charged
immediately. In winter, the battery is below 0℃Celsius, the battery is at low temperature, and t h e
charging should be carried out indoor s.
Note: There are three main ways to maintain sufficient range driving c apacity
1. As far as possible to drive at a low speed, the working current and speed of the electric vehicle into a
nonlinear rise relationship, the endurance and driving speed is inversely proportional, the battery lif e and
driving speed is inversely proportional, that is to say, maintaining good low speed driving habit s for
extending the battery usetime has great benefit s.
2. Asfar as possible to maintain the use of "frequent charging" habits, to prevent the battery fr om often
working in the "undervoltage" state, but also to reduce the probability of power loss.
3. The electric vehicles with low speed gear, try to use low speed gear. With low speed when dr i v in g , driving
ability is strong.
Charger and charging pr ec autions
1. Characteristicsof the charging t echnology
Charger internal using high-tech CPU chip, equipped with electric bicycle / electric vehicle b a tt er y
charging mode optimization program, using the random process control theory, the battery surplus
uncertain, after charging disconnected power time is uncertain, each time must be full of unc ertain under
the actual use of the optimal charging mode. In this intelligent charging mode, combined with batter y
maintenance technology, the online maintenance function can be realized without the intervention
of the user, and the battery can be reduced or not used for a long time automa tic ally repaired to the best
s t a t e.

13
Pay attention t o:
! In the area of unstable grid voltage, when the grid voltage fluctuation exceeds AC220V± 20%,
otherwise it is easy to cause the charger to undercharge the battery or the charger to f ail.
!This recharger does not need to be grounded
1. Open the charging port 2. Contact he charger

14
2. Charging
me thod
The charger indicator is"green" when the battery isfilled in the floating charge state, there isno need to cut
offthe power if there is an emergency, the indicator is "orange" can also be used.When y ou charge the
battery of the scooter, do not close the main switch. plug the charger output plug into the socket on the
vehicle body, and then insert the charger input power plug into the AV220V po w er sock e t.
3.Charging ins tructions
Charger in power to charge the battery, charging indicator display red state, said that the battery is in the
charger into constant current charging state, when the orange indicator, the battery has charg ed into 90%,
when the green and orange lights alternately, about an hour after the green battery c apacity , 100% full, if
continue to charge, online maintenance, maintain or restore capacity, maintenance af t er continue, the
charger into the battery micro current supplement, if still continue to charge the b a tt er y , and back to the
online maintenance stage.
! When charging, it is strictly prohibited to cover other items on the charger and battery box to
facilitate ventilation and heat dissipa tion.
! When carrying the charger, do not bump violently or collide, otherwise it iseasyto cause damag e.
4. Other important pr ec autions
When used and stored, liquid and metal chips should be prevented from penetrating into the charger to
prevent short circuit in damaging the charger .

15
! When used and stored, liquid and metal chips should be prevented from penetrating into the charger to
prevent short circuit and damaging the charger. The charger will generate some heat at the bottom of the
charger to prevent flammable and explosive items, such asflammable plastic or foam; the top and sidesof
the charger; please usethe charger in a well-ventilated environment. Ifyou smell the odor during the
charging process or find that the external temperature of the charger is too high (the surface
temperature of the shell is higher than 65℃),please stop charging immediately and send it to the
maintenance department for inspec tion.
! For the online maintenance of the battery, a proper long charging time is needed, and the user c an
maintain the battery online at the appropriate time and cycle. The long charging effect once a week is g ood.
The battery products of different battery factories, in different seasons (different oper a ting
temperatures), the online maintenance charger has an adaptive function. Automatic adjust the
charging voltage value, to ensure sufficient power without damage to the battery, battery c apacity
decline isslow, effectively prolong the working life of the b a tt er y .
Tip
! When the charger fails or the battery fails, the charger indicator may not change color for a long time
(generally more than 12h), the charger is always red, and the battery generates high heat. Please
immediately stop charging the battery and send it to the maintenance department for inspec tion.
! Online maintenance of the charger operation and other precautions refer to the use method c ont ent of the
charger .
