4. Setup Instructions
Follow these steps to prepare your Rubicon DX03 for use:
- Unfolding the Wheelchair:
Place the folded wheelchair on a flat, stable surface. Gently pull the backrest upwards while pushing the armrests outwards until the frame locks into its open position. Ensure all locking mechanisms are engaged.
- Adjusting the Seat and Footrests:
Ensure the seat cushion is properly positioned. Adjust the footrests to a comfortable height for the user, if applicable, and lock them in place.
- Connecting the Battery:
Locate the battery compartment, typically under the seat. Insert the detachable battery and ensure it clicks securely into place. Connect the battery cable to the wheelchair's power port. The power indicator on the joystick should illuminate.
- Initial Charge:
For optimal performance, fully charge the battery before the first use. Refer to the "Battery Management" section for charging instructions.
5. Operating Instructions
The Rubicon DX03 is controlled via an intuitive joystick. Familiarize yourself with its functions before operating.
- Power On/Off:
Press the power button on the joystick controller to turn the wheelchair on or off. The battery indicator lights will show the current charge level.
- Speed Adjustment:
Use the speed control buttons (usually '+' and '-') on the joystick to adjust the maximum speed. Start at the lowest speed setting until you are comfortable with the controls.
- Directional Control:
Gently push the joystick in the desired direction: forward, backward, left, or right. The wheelchair will move smoothly in response. Release the joystick to stop; the electromagnetic brakes will engage automatically.
- Maneuvering:
Practice in an open, safe area to become accustomed to the wheelchair's turning radius and responsiveness.
6. Folding and Transport

- Preparation for Folding:
Ensure the wheelchair is powered off and the battery is detached (recommended for transport, especially air travel). Remove any personal items from the wheelchair.

Locate the folding release mechanism (refer to specific model instructions if different). Typically, this involves lifting the seat or pulling a lever, then gently pushing the sides of the wheelchair inwards until it folds compactly. Ensure all parts are securely folded.
- Transport:
The lightweight design (approximately 40 lbs) allows for easy lifting and placement into vehicle trunks or storage spaces. The Rubicon DX03 is airline approved; however, always check with your airline regarding their specific policies for mobility devices and detachable batteries before travel.
