Wiring Connections
The QS-S4 throttle typically uses a 6-pin connector for connection to the scooter's controller. Carefully locate the corresponding connector on your scooter. Align the pins and push the connectors firmly together until they click into place. Ensure the connection is secure and waterproof.

Throttle Operation
Gently press the thumb lever to engage the motor and control your scooter's speed. Release the lever to decelerate.
Gear Selection (if applicable)
If your scooter's controller supports multiple gears, the display may show the current gear. Consult your scooter's manual for how to change gears, as this function is typically controlled by the scooter's main system, not directly by the QS-S4 throttle.
Maintenance
Cleaning
Wipe the display and throttle unit with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the plastic and electronic components. Ensure no water enters the unit.
Inspection
Regularly check the mounting screws for tightness and the cable connections for any signs of wear, fraying, or damage. Ensure the thumb lever moves smoothly without obstruction.
Storage
When not in use for extended periods, store the scooter (and thus the throttle) in a cool, dry place, away from direct sunlight and extreme temperatures.

User Tips
- Compatibility Check: Before purchasing, always verify the pin configuration (e.g., 6-pin) and voltage compatibility with your scooter's existing system to avoid issues. Some users inquire about 5-pin or 11-pin versions, so ensure you have the correct model.
- Wiring Location: Pay attention to the USB port location if your model includes one, as it might be on the side or integrated differently depending on the specific variant.
- Kugoo G1 Compatibility: While listed as compatible with Kugoo X1, always double-check specific model compatibility for other Kugoo models like G1, as variations can exist.
