ATTENTION ●Please keep it in the middle of the seat cushion. If it is too
forward or backward, the load ratio of front and rear wheels
will change, causing the handle to vibrate and causing danger.
1.Whether the tire pressure is normal. According to the
depression of the tire grounding part, judge whether
the air pressure is appropriate. If the air pressure is
abnormal, check it with a tire measure. Generally
speaking, the front wheels of ordinary tires are 175±5kpa
and the rear wheels are 200±5kpa. Vacuum tire: front
and rear wheels 250±5kpa.
2.Whether the tire is cracked or abnormally worn.
3.Whether the tire is embedded with nails, stones and glass.
4.When the tire is used to the tread wear mark, the
tire should be replaced.
1.Check whether the rear-view mirror is dirt or damage,
keep the mirror clean, replace it in time if it is damaged.
2.From the driver's position, observe whether the
rear-view mirror can see the rear and side road
conditions respectively.
1.Insert the key into the electric door lock, turn the power
switch clockwise to turn on the whole vehicle circuit.
2.Check power supply and lighting circuit. The front
and rear brake system. Reflector, license light.
Handlebar and front and rear wheel. Parts such as
tires ensure that there is no abnormality in the scooter.
3.Hold the handlebars with both hands, stabilize the
scooter hit the main support or the side support to
make the rear wheel land, support the ground with
the left foot and place the right foot in the pedal
position. After you are seated on the scooter, slowly
rotate the speed control knob counterclockwise inward,
and the scooter will start to run.
You can use the throttle to adjust acceleration or
deceleration to control scooter speed. Turn the throttle
counterclockwise inward, and the speed will change
from slow to fast. On the contrary, the speed will slow
down from fast. After loosening, the throttle will
automatically reset and the motor will stop working.

whether the appearance is deformed, and whether
the motor phase wire is damaged.
3.When used in rainy days, the motor cannot run in
deep water, and the water surface cannot exceed the
position of the rear axle.
4.The motor hub cannot be violently impacted, and the
motor cannot be forced to run under the condition of
locked rotation. Overloading of the motor is strictly
prohibited.
5.If the motor is found to be operating abnormally,
it shall immediately stop operation and send it to the
authorized repair shop designated by YADEA for
repair and replacement.
1.Regularly check whether the controller fixing screws

Parking methods

This scooter uses maintenance-free lithium battery, the
operating environment temperature is 0℃~+45℃, too
low will reduce its effective capacity, too high will affect
its service life. Therefore, in winter or cold areas, it is
normal when the continuous distance after one charge
is reduced. When the temperature rises above 20℃,
its function will resume naturally. The battery is an
important component to protect the good performance
of the scooter. Please pay attention to proper protection.
29 30
Use and maintenance of lithium battery
Please do not use the electric energy to the minimum
allowable voltage every time you ride. Normally it should
be the best to charge the battery once when the battery
level is about 30%. When the under voltage indicator
flashes, you must charge the battery. It is best to form
the habit of charging after riding every day, which is of
great benefit to the battery life. If the battery had been
left for 3-7 days(after battery used out), it may be
permanently damaged. Therefore, please charge the
battery as soon as possible after use.
There are two charging methods: One is to remove the
battery and charge it, one is to charge directly on
the scooter.
Charging attention
3.Unauthorized modification of controller circuits is
strictly prohibited.
4.Regularly check controller lines , fuses, etc.
5.If the controller is found to be working abnormally, it
shall immediately stop operation and send it to the
authorized repair shop designated by YADEA for repair
and replacement.

ATTENTION ●After the battery temperature is protected, when the temperature
returns to normal, plug and unplug the battery plug again,
and the normal use state can be restored.
WARNING ●The separate operating instructions in the battery package and
charger package are also part of the product. Please read
carefully before using.
●Please read carefully and understand the warning words and
precautions on the labels of battery and charger housings.
DANGEROUS ●Prohibited charging areas such as supermarkets, shops,
warehouses, kitchens, bedrooms and other flammable venues.
