4. Operating Instructions
4.1 Adjusting for Your Height
Proper height adjustment is crucial for safe and effective inversion. The height adjustment mechanism is typically located on the main frame. Adjust the height so that your head is comfortably supported by the backrest and your body is balanced when your ankles are secured.
- Locate the height adjustment pin or lever.
- Pull out the pin or release the lever and slide the backrest assembly up or down to match your height.
- Ensure the pin locks securely into place at the desired height setting.
4.2 Securing Your Ankles
The ankle support system is vital for your safety. Always ensure your ankles are firmly and comfortably secured before inversion.
- Step onto the foot platform and place your ankles between the foam rollers.
- Engage the ankle locking mechanism. This may involve a lever, pin, or clamp. Ensure it is fully engaged and your ankles are snug without being painful.
- Test the security by gently pulling your feet upwards. Your ankles should remain firmly in place.
4.3 Inversion Process
The Trainer In-Gravity 1800 allows for smooth and controlled inversion. The movement of your arms over your head is sufficient to initiate inversion and return to an upright position.
- Initial Position: Sit on the backrest with your back flat and ankles secured.
- Initiate Inversion: Slowly raise your arms over your head. The table will begin to tilt backward.
- Control Inversion Angle: Use the BALANCE PRO System to set your desired inversion angle (20°, 40°, 60°, 80°, or free inversion up to +/- 90°). Lock the angle using the provided mechanism. For free inversion, maintain control by holding the handles.
- Return Upright: To return to the upright position, slowly bring your arms down to your sides or grasp the handles and pull yourself up.
- Safety Belt: Always use the safety belt to prevent over-rotation, especially when experimenting with free inversion.
