2.Intended Use
·An electric scooter is intended for sport and entertainment purposes, not for use as a
means of transportation, but the transportation faction of the product once you drive it
into public areas (as permitted by the laws and regulations of your region and
country)also carries potential safety risks for all vehicles. Drive strictly in accordance
with the instructions in this manual to ensure the safety of yourself and others to the
utmost extent, and to ensure compliance with national first-level traffic laws and
regulations of various provinces and cities, such as traffic regulations, etc.
·Please note: Once you drive an electric scooter on public roads or other public places
(as permitted by the laws and regulations of your region and country regarding the use
of electric scooters on public roads or other public places), even if you fully comply with
this safe driving guide operation, you may also face risks caused by illegal driving/im-
proper operation by others, or other vehicles. Just like when walking or riding a bicycle,
you may also be injured by other vehicles. As with any vehicle, the faster you drive an
electric scooter, the longer the distance required to brake, and emergency braking on
smooth surfaces may also cause the wheels to slip and lose balance or even fall over.
Therefore, it is very important to be vigilant when driving, maintain a proper speed, and
maintain a reasonable and safe distance from other people and vehicles. When driving
on unfamiliar terrain, stay alert and drive at a low speed.
·Please respect the pedestrian's right of way when driving. Avoid frightening pedestri-
ans, especially children.
·When driving in countries and regions where there are currently no national standards
and regulations related to electric scooters, such as China, please be sure to comply with
the safety requirements for drivers in this manual. Zhejiang Oukai Automobile Industry
Co., Ltd. will not bear any direct or joint liabilities for any financial losses, losses of life,
legal disputes, or any other unfavorable events that occur due to the violation of the
recommended uses indicated in this manual.
·To avoid potential injury, do not lend the electric scooter to people who can't operate
it. If you give the electric scooter to a friend to use, please be responsible for your
friend's safety, teach them to operate the scooter, and tell them to wear protective
equipment.
·Please perform a basic inspection of the electric scooter before each driving. If you find
that there are loose parts, the battery life is obviously reduced, the tires are excessively
worn, the steering makes abnormal noises or malfunctions, etc., please stop using the
scooter immediately, and do not force it to drive.
