Self-balancing Scooter K5
User Manual
Foreword
Thank you for using our product. To easily use the product, we have provided detailed
instructions in this user manual to introduce the product, its usage and other related
information. Please read this user manual carefully before you use the device. Please
excuse any typographical or translation errors that may be in this user manual. This
user manual could be amended without prior notice.
1. Product Description
The self-balancing scooter has three sections. The two axes control the left and right
sides of the scooter’s body; the two sides can operate independently while moving,
and will not interfere with each other. The scooter has two wheels; the width between
the wheels does not exceed an average adults’ shoulder width, and the scooter is
battery-powered. The scooter has a handle that can be used to lift the scooter with one
hand. The handle has a built-in display, and indicates parameters such as battery
power, speed, temperature and Bluetooth connectivity. The front of the handle is
equipped with a headlight and sensor; the sensor detects light levels and automatically
switches on the headlight when visibility is low, and provides illumination while
using the scooter at night. The scooter does not have any special brakes; when the
rider leans forward, the scooter moves forward, when the rider stands erect, the
scooter stops, and when the rider leans back, the scooter moves in reverse. The
scooter uses the principle of dynamic equilibrium; when the body moves, the center of
gravity changes and continues to change and balances itself. For example, when we
lean forward, the human body is out of balance; the body's natural balance system
informs the brain of the situation, and the brain issues instructions to different organs
to regain balance. The Self-Balancing Two-axle Scooter provides an alternative to
walking, while replicating the human body’s high-precision self-balancing system. It
provides mobility at low cost, is quiet and convenient. The scooter uses lithium
batteries; when the battery is fully charged the scooter can be used to continuously
travel 20 km; when the low battery indicator is displayed, you need to recharge or
replace the batteries; while charging, it is needed to be charged via the whole device.
Mileage may differ based on the way you ride, related road conditions, grassy slopes,
etc., as they may affect power consumption.

4. Usage Safety Rules
4.1 Mandatory Requirements
Understand and strictly comply with local traffic laws.
Always wear a helmet and knee, elbow and wrist guards while using. This
provides you effective protection.
Check the battery charge status. On switching on the scooter, check the battery
charge level; do not travel a long distance if the battery charge indicated is less
than 2 bars.
Check the scooter’s basic status. Check that there are no loose, missing or
damaged parts, and that there is no abnormal sound, or that the warning alarm
does not continuously ring.
Before using the scooter, ensure that you are in good physical condition and
completely conscious; and that you have not consumed any alcohol, sedative or
other psychotropic drugs 6 hours prior to using the scooter.
4.2 Strictly Prohibited Actions
Do not use the product in any area prohibited by national/regional laws and
relevant administrative organizations.
Please be careful when you pass through a door, or approach a gate, tree branches,
all kinds of sign posts and boards, or other low barriers while you are riding the
scooter, to avoid having a head-on collision.
Do not use the scooter in dangerous areas or areas that fail to meet product usage
requirements, such as pits/fissures, more than 20 degree steep slopes, more than
3cm-deep water, etc.
Do not use the scooter on motor vehicle lanes. Some countries do not allow this
type of scooter to be used in a bicycle lane, subject to local regulations.
This self-balancing scooter is designed to carry only 1 person, and more than 1
person is prohibited; in particular, do not hold or carry an infant while using.
Children less than 14 years old and elderly people more than 65 years old are
prohibited to use this scooter without appropriate supervision by a competent
family member. Pregnant women, inebriated persons, persons with mental illness,
heart patients and persons with limited physical capability (such as disabled
people), are prohibited to use this scooter.
Do not use this scooter in an unsafe environment, such as a place with flammable
gases, vapors, liquids, dust or fibers, or in other dangerous situations that may
cause a fire, or explosion hazard, or workplace accidents.
Don't reverse and turn at high speed. Avoid using phones and engaging in
behavior that diverts your attention while using the scooter.
Do not violate any other provisions listed in this manual, especially "WARNING"
and "CAUTION" notices that clearly indicate prohibited actions.
4.3 Legal/Safe Usage Considerations
Before using the scooter, actively understand local traffic laws to ensure legal use,
and pay attention to surrounding people and objects to avoid collisions.
Use the scooter at safe speed and require others to do so as well, and use under
controllable conditions. Maintain safe distance from pedestrians and vehicles, and
be ready to stop when required.
Develop good usage habits, and avoid rapid acceleration, deceleration, start and
braking.
Respect pedestrian's right of way and avoid frightening them, especially be
careful with children. While overtaking pedestrians, warn them and slow down.
Overtake pedestrians from their left side (based on local traffic rules and
regulations of your country). When coming face to face with a pedestrian, keep to
the right (based on local traffic rules and regulations of your country) and slow
down.
When there are numerous pedestrians, make sure to slow down and ride at same
speed as the pedestrians. Overtake pedestrians only when sufficient space is
available. It is highly dangerous to pass through crowds at high speed.
While traveling with other scooter users, keep suitable safe distance, and avoid
dangers and obstacles; do not ride the scooter side by side unless there is enough
space available for pedestrians.
4.4 Smart Security Alarm/ Automatic Protection
Under the following conditions, the scooter will automatically limit the speed, that
is the maximum speed is automatically limited to a safe range:
Excessive speed while moving forward: When the speed of the scooter is too
high (speed limit 4km/h～12km/h), you cannot accelerate further as the scooter's
speed limit mechanism is triggered, as the rider is leaning excessively, leading to
high speeds. Under such a scenario, adjust the body's inclination level to maintain
the body and the scooter at the same horizontal line, or else you may trip and lose
your balance on the scooter if you continue to accelerate the scooter and maintain
your body's angle.
Overload or riding on a slope for a long time: When the load exceeds the
scooter's designed safety limit (normally occurs in case of riding on steep slope,
pit, overweight rider, riding on a slope for a long time, etc.), the motor may
become hot.
Low battery: When battery charge level is less than 40%, maximum speed will
gradually reduce under normal riding conditions, and the speed may be limited
even if your speed is not up to 12Km/h. When battery charge level is about 30%,
typically maximum speed limit is about 10km/h
5. Operation and Usage
5.1 Getting Ready
While riding for first time, select an appropriate site and take your time to
understand how to use the scooter. The site should at least measure 4×4m (16m2),
and can be indoors or outdoors, have a flat surface, and should be free of
obstacles like motor vehicles, bikes, pets, children and other objects that may
divert your attention.
Please have a riding instructor or guide who has previous riding experience for
this type of scooter, or has read this manual or has watched safety instructions
and warning video, and can assist you in riding the scooter.
Make sure to wear a helmet and protective gear to avoid possible injuries.
Comment [AJ1]: Have added this clause as the
traffic rules in countries that were ruled by the
British or were influenced by the British,
require drivers to drive on the left such as
Hong Kong, Singapore, Malaysia, India,
Australia, etc., as opposed to driving on the
right in China, USA, etc.
5.2 Start Up
Press the "On/Off" button. The scooter successfully starts up and you will hear a
little "beep" sound, and the LED panel lights switch on, indicating final
temperature, battery level, and speed information.
5.3 Precautions Before Using
1. Stand behind the scooter and adjust the handle till the pedals are level. At this
time, the scooter is at a balanced state, and ready for use. First step on one of the
pedals with one foot; place the other foot after you hear the "beep" sound, which
indicates the scooter is in appropriate pressure state and maintains balance. If the
pedals are not balanced, readjust them and make them level.
2. Balance Test : Place the scooter on a horizontal position, and press the "On/Off"
button for 3s; release the button when you hear the "beep" sound and the side
indicator LED lights flash. After conducting the balance test, you need to perform
the riding test.
5.4 Stepping On and Maintaining Balance
Compared to riding a regular motorbike, it is easier to learn to operate the
self-balancing scooter. Most beginners only take 3min to expertly operate the
scooter. Have an instructor stand in front of the scooter, and hold your two hands
so that you avoid losing your balance due to nervousness or improperly
positioning yourself, as you step on to the scooter for first time.
1. After stepping on the scooter, look straight ahead, rather than looking down.
2. First step on the pedal with one foot, and maintain your body’s weight on the
pedal as you align your center of gravity (imagine your stance when you are
taking a step forward).
3. Slowly step on the pedal with the other foot (imagine a standing stance on flat
ground), trust your capability to balance on the scooter, stay calm and relaxed,
and look forward.

5.5 Move Forward / Reverse/ Brake
1. Slowly lean forward; the scooter will move forward. Stand erect to slow down
and stop. Control the speed appropriately. Practice these movements several
times to understand how to control and move the scooter using your body’s
center of gravity.
2. Slowly lean back to reverse the scooter. Stand erect to slow down and stop.
Practice these movements several times. Avoid colliding with walls or obstacles
to avoid falling down.
3. While moving forward or reversing, gently straighten your body. When your
body is vertical to the scooter, you can move forward, reverse or stop the scooter.
Evenly distribute your weight to the middle of the pedal to achieve stable
braking.

5.6 Turning
To turn, shift the weight of your feet towards the direction you wish to turn. Shift the
weight of both feet towards left or right, to turn the scooter in the corresponding
direction.
1. First practice turning in place. Slowly lean and shift the weight of your feet
towards the desired direction, and the scooter will turn in place; stop leaning
when the scooter reaches the desired angle. Practice turning left and right several
times to master how to turn.
2. Turning during movement. After you are familiar with moving forward, reversing
and turning in place, try to turn while moving. Lean your body towards the
desired direction. Practice several times to master how to turn.

5.7 Climb Off
Climbing off is similar to taking a step back. When you are ready to climb off, ensure
the scooter is balanced. You should not simultaneously lift both feet from the pedals.
While climbing off, properly maintain your center of gravity and do not move forward
or reverse, and do not turn.
5.8 Speed Limit
After starting the scooter, when the speed crosses 12km/h, the scooter will sound an
alarm. You may adjust the speed limit using the mobile App.
5.9 Using the Charger
1. Charge the battery with the charger provided with the scooter. Directly insert the
DC plug into the charging port. The charging indicator light turns red during
charging and green after charge is full.

7. Routine Care and Maintenance
7.1Cleaning and Storage
Clean the scooter regularly after use to maintain best performance.
Wipe the external surface of the scooter with a soft cloth dipped in clean water.
Wash the tires and the scooter's undercarriage with a household use shower
nozzle or a gardening hose (less than 1Mpa or 145PSI water pressure). After
washing, make sure the water drops drain away, and dry the scooter in a
well-ventilated environment to avoid rusting of certain steel components.
If it is difficult to remove dirt from the plastic surface, apply toothpaste and clean
the dirt with a toothbrush, and wipe clean with a wet cloth. This method can be
also used to remove some minor surface scratches.
If the scooter is not used, store it indoors in a cool and dry environment. Avoid
storing outdoors for long periods of time. Direct sunlight or very hot/ cold
outdoor environment may accelerate aging of the scooter's outward appearance.
Caution!!!:
Before cleaning the scooter, turn off the scooter, remove the charging cable, and
tightly cover the charging port's plastic cover! Otherwise there may be possibility of
electric shock or serious malfunction.
Do not directly wash the scooter with a high pressure water gun used for car washing,
or soak the scooter in water, as it may lead to severe irreparable malfunction due to
moisture accumulation or water entering interior components.
Do not clean the scooter with gasoline, kerosene, acetone and other corrosive and
volatile chemical solvents, as they may damage the scooter's appearance and internal
structure.
7.2Battery Maintenance
The battery is the scooter's component that needs the most amount of maintenance.
The battery may maintain good performance even after the scooter has been used for
20000km-30000km if well maintained; but its charging capacity may deteriorate or it
may get damaged within several months if improperly maintained. Perform the below
mentioned regular inspection and maintenance to prolong the battery's service life:
1. Store the battery at 0°C～40°C in a dry indoor environment as much as possible.
High and low temperatures may influence the battery's service life. Do not store
or use the battery at less than ﹣20°C or more than 50°C.
2. Store the battery in dry and cool environment as much as possible. It is possible
to damage the battery due to internal moisture condensation and water retention
in an extremely humid environment.
3. During daily use, avoid fully depleting the battery's charge. Fully charge the
battery when the battery level is at 1 or 2 bars. Frequent charging cannot impact
the battery's service life, while long term low battery may seriously influence the
battery's capacity and service life.
4. If the scooter is not used for long periods while the battery is installed, the battery
level may continuously deplete; therefore:
a) If not used during a short period of time (less than 30 days), keep the battery
fully charged, but you don't need to remove the battery for storage.
b) If not used for long period of time (more than 30 days), after fully charging,
remove and store the battery in a cool and dry environment.
c) If not used for a long period of time (more than 180 days), charge the battery
once every 3-4 months to maintain battery's capacity and service life.
5. A safe lithium ion battery core is used in the scooter's battery, and a protective
circuit board with multiple protection functions is used. Under normal use and
even during collision the battery will not catch fire or explode.
6. Typically, a fully charged battery may lose most of its charge after about 50～70
days' standby; and when the battery level is almost exhausted, it will be
completely depleted after about 10～20 days' standby. If the battery is not
charged regularly, it is possible the battery may be damaged due to over discharge.
Such damage is irreparable and excluded from the warranty.
Caution!!!:
Don't pierce the battery with a sharp object
Don't smash the battery with a heavy object.
Do not put the battery in fire or in natural sources of water to avoid risk and
environmental pollution.
7.3 discarded, discarded treatment
When it reaches the retirement standard or discard for the scooter or battery, it sho
uld be recycled after sorted according to regional regulations and standards
