For optimum performance, inflate your Sherrin to the recommended kPa as stipulated around the mouthpiece of your Sherrin.
- Sherrin balls will have a recommended inflation unit printed around their inflation valves ie 69kPa, 45kPa, 30kPa, 25kPa etc.
- This metric pressure unit is kPa (kilopascal). NOTE: Be careful to not confuse psi (pounds square inch) with kPa as psi has roughly 10x more pressure than kPa and will rapidly and easily damage your ball. (Note: 6.9 kPa = 1 pSi).
- This is not a guide this should be considered a maximum. If you exceed the recommended inflation you risk damaging the stitching and also voiding the warranty.
- If you do over-inflate a ball, release the pressure immediately. It may not be apparent just by looking at the ball that it is over-inflated, another sign is if it is hard to the touch, after use, the stitching can possibly give way.
- Over-inflation can cause your Sherrin to go out of shape and lead to malfunction.
- Ensure to lubricate the needle before you inflate the ball each time.
- If using a hand pump make sure to place the ball on a flat surface as the needle can heat up and bend or snap off if weight is put on it.
