Locate the ball on the PopToss in a position where none of the threads on softball touch the Ball Striker upon impact. The ball striker should impact a smooth surface of the ball.
If the timing becomes inconsistent, the very first thing you should do is a periodic oiling of the bottom cylinder of your PopToss.
PopToss provides a lifetime warranty on each unit. You pay one time at purchase and never pay another dime for life. Even though your PopToss will work flawlessly for years, we may have to send you the bottom cylinder containing both valves. This video describes the proper assembly of your unit when you get the bottom cylinder from us.
