Like all vehicles, the faster you drive a kick scooter, the longer the distance required to brake, it is recommended to ride in a relatively closed and flat road

environment (such as inside a community, park, special closed venue , etc.). Therefore, it is important to be vigilant and maintain the proper speed during

driving, as well as to maintain a reasonable safety distance from others and vehicles. Please be aware of your surroundings and ride at low speed when on

unfamiliar terrain.

5. Please respect the pedestrians’ right of way when driving. Avoid scaring pedestrians, especially children. Alert pedestrians when passing behind them and slow

down when passing. Pass from the left side of pedestrians if possible (applicable to the country where the vehicle is traveling right). When facing pedestrians,

keep to the right and slow down to pass.

6. When riding in countries and regions where there is currently no relevant regulations for kick scooters, you must strictly comply with the safety requirements for

riders in this Manual. The manufacturer will not bear any direct and joint liability for any property loss, personal injury, accidents or legal disputes caused by the

3. Confirm that the device will power on and off after assembly.

4. Lock the screws on both sides alternately with the hexagon wrench in the packaging box (tightening torque: 4~5N*m), that is, the assembly is completed.

Folding and handling

Folding

Confirm that the kick scooter is powered off, then hold the vertical tube, open the folding wrench, align it to the position of the mudguard hook, and finally hook the

hook under the dashboard to the rear end of the body. Press the buckle button on the mudguard when opening. After the hook under the dashboard is separated from

the folding buckle, straighten the vertical tube to lock the folded plate and then turn the folding wrench back.

WARNING! As with any mechanical component, a vehicle is subject to high stresses and wear. The various materials and components may react differently to

wear or fatigue. If the expected service life for a component has been exceeded, it may break suddenly, therefore risking causing injuries to the user. Cracks,

scratches and discoloration in the areas subject to high stresses indicate that the component has exceeded its service life and should be replaced.

Traffic conditions in the city has many obstacles to cross such as curbs or steps. It is recommended to avoid obstacle jumps. It is important to anticipate and

adapt your trajectory and speed to those of a pedestrian before crossing these obstacles. It is also recommended to get out of the vehicle when these obstacles

become dangerous due to their shape, height or slippage.

WARNING! Keep plastic covering away from children to avoid suffocation.

Get closer to your seller so he can refer you to an appropriate training organization.

Avoid high traffic or overcrowded areas.

In any case, anticipate your trajectory and your speed while respecting the traffic rules, sidewalks and the most vulnerable, the pedestrians.

Notify your presence when approaching a pedestrian or cyclist.

Walk while crossing the protected passages.

In all cases, take care of yourself and others.

Do not divert the use of the vehicle.

This vehicle is not intended for acrobatic use.

Caution, the brake may become hot in use. Do not touch after use.

Disc brake debugging

Excessive braking force

If you feel that the brake is too tight, use a wrench to loosen the brake arm nut 1 counterclockwise, return the brake cable to shorten the length of the exposed tail, and

lock the nut clockwise 1 to confirm the brake force and complete the adjustment.

Insufficient braking force

If you feel that the brake is too loose, use a wrench to turn the fine adjustment screw 3 counterclockwise, and then confirm the braking force by the brake action, and

tighten the limit nut 2 clockwise after completion.

Changing Brake Pads

●Completely loosen the brake cable and remove the brake calipers from the vehicle body with a 4MM hexagon wrench.

●Tilt the tail end of the brake pad return spring and remove it.

●Remove the old brake discs one by one and clean the brake piston with a clean cloth.

●Put the new brake discs in one by one, and push the two brake discs apart with tools.

●Push the return spring to the bottom through the gap of the brake discs.

●Install the calipers to the vehicle body, thread the brake cable and lock it in place.

Handlebar shaking debugging

Check whether the vertical tube screws are loose. If so, fasten the standpipe screws first, and then fasten

the two screws of the folding mechanism with a 6mm hexagon wrench.

Use of the extension nozzle

If your kick scooter front and rear tires are underinflated, please use the extension nozzle to connect the

car body tires to inflate. First remove the front and rear tire inflatable nozzle cap, and then tighten the

extended inflatable nozzle and tire inflatable nozzle,and connect the pump to inflate after they are to be
