4. Maintenance

To ensure the longevity and hygiene of your Yes4All Half Ball Balance Trainer, follow these maintenance guidelines:

• Cleaning: Wipe down the surface of the balance trainer with a damp cloth and mild soap after each use. Avoid abrasive cleaners or solvents that could damage the PVC material.
• Storage: Store the trainer in a cool, dry place away from direct sunlight and extreme temperatures. Prolonged exposure to heat can cause material degradation.
• Inflation Check: Periodically check the inflation level. If the ball feels soft, re-inflate it to the recommended firmness using the provided air pump.
• Inspection: Regularly inspect the balance trainer for any signs of wear, tears, or damage. Discontinue use if any damage is found to prevent injury.

5. Troubleshooting

If you encounter any issues with your Yes4All Half Ball Balance Trainer, consider the following common troubleshooting steps:

• Difficulty Inflating: Ensure the pump adapter is securely attached to the air pump and fully inserted into the air hole. Check for any blockages in the pump or valve.
• Losing Air: Verify that the air plug is fully and securely inserted into the air hole after inflation. Inspect the ball for any punctures or leaks. If a leak is suspected, apply soapy water to the surface to identify bubbles.
• Unstable During Use: Ensure the trainer is placed on a flat, non-slippery surface. Check that the ball is adequately inflated to the recommended firmness.
