INFLATION HAS TO BE PERFORMED BY AN ADULT: DO NOT USE ANY AIR COMPRESSOR Inflation should be made using the proper adapter. This is not necessary when using a foot pump (MAX ATM. 0.1-PSI 0.5). We recommend the Two Way Action Hand Pump for small to medium sized balls. Remember to inflate the ball avoiding places where sharp objects can be found. Inflation should be made at room temperature (20C/70F). BRQ balls need to be inflated little-by-little but energetically to reach the diameter which is shown on the ball. Do not inflate over the recommended diameter. WARNINGS: DO NOT USE AIR COMPRESSOR Please read carefully the instructions on the box. Any heat source, rough surface or any contact with pointed or sharp objects have to be avoided. Please be careful while wearing clothes with zips, rings or watches. Check the ball before using it. The manufacturer is not liable for any damage caused by wrong ball usage. In any case, an evidence of purchase and its date or the control number must be provided. For physiotherapy exercises follow the instructions provided by your practitioner/therapist. Not suitable for children below 3 years. It includes small parts. For any need take note of the manufacturer's address. IMPORTANT SAFETY INSTRUCTIONS: For your safety, do not ride your ball near stairs. In case of puncture, we suggest not to repair the ball. Once repaired, it would not be in compliance with safety rules anymore. To clean the ball, wash it with soapy water. Do not use any brushes, abrasive sponges or chemical cleaners.
