- Always wear helmets and knee pads.
- Stand on the platform with one leg, push off with the other.
- Step onto the scooter once in motion and apply throttle (accelerates only above 3 km/h).
- Release the throttle to slow down; energy recovery systems assist in braking. For urgent braking, firmly press the left disc brake lever.
- Lean body slightly and turn the handlebar in the desired direction for turning.

Maintenance Features:
- Cleaning: Use a soft, damp cloth to wipe the vehicle. Avoid alcohol, petrol, kerosene, corrosive solutions, volatile chemical solvents, or strong water pressure. Ensure the scooter is off and the charging port is covered after charging.
- Storage: Store in a dry, cool place, away from direct sunlight, extreme temperatures (above 50°C or below -20°C), and fire.
- Battery Maintenance:
- Use only original AC adapter.
- Do not open or disassemble the battery.
- Avoid contact with metal objects to prevent short circuits.
- Dispose of used batteries according to local laws.
- Charge the battery after each use to prolong its life.
- If not used for 30 days, charge the battery and store in a cool, dry place. Recharge every 60 days to prevent battery failure (not covered by warranty).
- Avoid fully discharging the device.
- Battery performance and range decrease in temperatures below 0°C.
- Disc Brake Adjustment: If the brake is too tight, loosen caliper screws with a hex wrench, pull back the brake cable slightly, then tighten. If too loose, loosen screws, pull out the cable to lengthen, then tighten.
- Handlebar Adjustment: If the handlebar or stem sways, use a hex wrench to tighten screws on the folding mechanism.
- Tire Inflation: Use a connecting pipe to pump the wheels. Remove the cap from the pin, tighten the fitting, and inflate.
- Tire Removal and Installation:
- Removal: Deflate the inner tire, pinch the tire to release air. Use two crowbars (not included) to pry up the outer tire, starting away from the valve. Pull the air valve out of its hole, then remove the inner tire. Wrap crowbar ends with fiber cloth to prevent damage.
- Installation: Inflate the inner tire slightly. Place the hub on a desk, ensuring the outer tire's arrow aligns with the wheel's forward direction. Insert one side of the outer tire into the hub groove. Insert the air valve of the inner tire into its hole, then insert the inner tire clockwise into the outer tire. Insert the remaining outer tire lip using a crowbar. Inflate the inner tire to 15-20 PSI, check safety lines, then inflate to 45-50 PSI. Tighten the air valve cap. Wrap crowbar ends with fiber cloth to prevent damage.
