Troubleshooting

Troubleshooting of the whole vehicle

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 tightened.
