Your question was: How do I inflate the Pro Series Ball?
Our experts said: The measuring tape has three holes: #1 is at one end, while #2 (initial inflation size) and #3 (maximum inflation size) are at the end.
Before inflating, spread out the measuring tape on the floor to its full length, with the un-inflated ball in the center of the tape. Position the ball so its inflation hole is facing up.
Wrap the measuring tape around the ball so holes 1 and 2 join at the inflation point of the ball.
Slowly inflate the ball through holes 1 and 2 of the tape.
As the ball fills, be sure the tape remains centered on the circumference of the ball and does not get twisted.
Proper inflation is reached as follows: When wrapped around the ball’s diameter, starting from and ending at the balls inflation point, holes 1 and 2 (initial inflation size) in the measuring tape should meet at the inflation point without any gaps, or without being stretched.
Insert a plug into the inflation port of the ball until the plug is flush with the surface of the ball.
Note: The ball may continue to expand even after air is no longer being added to the ball from the warming and expansion of cooled, compressed air. This expansion is typically greater with compressed air than with manual pumps.
Do not use the ball for at least 24 hours to allow the material to adept to the expansion.
After 24 hours, re-measure the ball with the measuring tape, using holes 1 and 3 to determine maximum size. If the ball is below the maximum size, and the additional size or firmness is desired, remove the plug and add air. The allowable operating range of the ball is between holes 2 and 3 of the measuring tape.
Keep in mind that the ball may continue to expand even after air is no longer being added to the ball.
If additional air is added, wait 24 hours to allow for expansion. If the ball is firmer than desired, deflate the ball to achieve desired size and firmness. The allowable operating range of the ball is between holes 2 and 3 of the measuring tape.
NOTE: If the ball exceeds maximum inflation size, discard the ball. Exceeding the maximum inflation size damages the material, which may cause the ball to burst, possibly causing injury.
