With proper care, the Zooka pitching machine should give years of trouble-free use. Simple cleaning and battery charging after each use will prevent most problems. The pitching machines have built-in self-diagnostics and will display error codes when error conditions occur. Users should then refer to the troubleshooting section of the owner's manual for advice on clearing common problems.
