How to Use and Precautions
(1) Safe use
1. In the benefit of you and the others, please read this user manual carefully before using the
scooter. DO NOT use it until you have adequate knowledge about its performance. DO NOT
lend it to whoever is unfamiliar with the operation of this scooter.
2. Please observe traffic rules consciously. Ride your scooter in the non-motor lane. DO NOT
carry a passenger.
3. Pleas brake in advance to ensure the scooter stops within an appropriate braking distance.
4. DO NOT ride in waterlogged area.
(2) Check before use
1. Check whether the wheels rotate well.
2. Check whether the battery has been fully charged.
3. Check whether the braking system works flexibly and make sure that the power is cut off
when braking.
4. Check whether the folding mechanism has been locked up.
(3) operation
1. Start the button switch on the left side of the battery box and then turn on the power switch
on the meter. Then regulate the speed threshold to an appropriate gear, press the speed
regulating handle slowly and rotate it to an appropriate position based on speed to keep the
scooter running at a safe speed.
2. Please keep the two feet one behind the other to make the human body in the most
appropriate position while riding.
3. Avoid frequent braking or startup while riding, which helps prolong the battery’ service life.
When decelerating, release the speed regulating handle until motor power is cut off.
(4) Use of battery and precautions
1. The battery unit consists of sealed li-ion batteries that feature long service life and leakage-
proof sealed structure. Considering the fact that the battery unit has been in storage for a long
time since it is manufactured, please make sure it is fully charged before using the scooter for
the first time. Recharge the battery unit timely in the event of low battery during riding. Have
the battery unit fully charged before long storage, and charge/discharge once a week if

15
possible.
2. Using the dedicated charger only, otherwise battery’s service life might be undermined.
Battery indication: obverse battery level while riding since the observed result in the stationary
state is inaccurate. Charge the scooter timely in the event of low battery indication.
3. DO NOT touch the metal contacts on the charger socket with hand or metal that may cause
short-circuit in case of accidents.
(5) Use of charger and precautions
1. Plug the charge’s out put terminal into charging hole on the battery unit, then connect the
charger to AC 100-200V/50-60HZ power supply and make sure charging indicator is on. To
avoid damage to the controller, power the scooter off during charging time that can last 3
hours.
2. Trip distance can decline at a low temperature.
3. Charging mode: it is recommended that the scooter be charged once a day if possible. The
whole charging process is automatically controlled: when the charging indicator turns to green,
it means the battery unit has been fully charged and is in a floating charge state. Floating
charging doesn’t cause any damage to batteries. At this point, it is unnecessary to stop
charging sine very little energy is consumed during floating charge.
4. In case of damages, avoid violent bump or impact when using, shipping or carrying the
charger. Keep liquid or metal filings away from the charger in case it is short-circuited or
damaged.
5. DO NOT place inflammables under the charger because heat is generated while it is
working. It is prohibited that the charger is covered or surrounded by anything so as not to
affect heat dissipation. The charger shall be used in a well-ventilated place. In the event that
there is peculiar smell, smoke, or excessive temperature (higher than 65℃)from/onthe
charger, stop charging immediately and have it repaired in the maintenance department.
6. In the event that the charging indicator doesn’t turn green for long time (generally longer
than 10 hours) while the charger is in the charging mode all the time, particularly along with a
high battery temperature due to charger failure, battery damage or low voltage, please stop
charging immediately and have the scooter repaired in the maintenance department.
7. For sake of adaptability between the charger and battery, please DO NOT charge your
scooter using chargers other than the dedicated one.
(6) Routine maintenance and precautions
1. Rotate the speed regulating handle slowly rather than violently.
2. DO NOT washing the scooter directly to avoid short-circuit of electric/electronic parts due to
moisture/water.
3. For safety sake, turn the main power switch off when parking the scooter.
4. Replace for a new brake pad when 1/3 of it has been worn out and braking effect is
impacted.
5. Remove the contaminants adhered to brake disc or other surfaces.
6. Check whether or not the electric part of power-cut brake is well connected and whether the
fasteners are loose. Make timely adjustment if any.
7. Make periodical examinations and maintenance, generally once every six mouths.
