The Tennis Tutor is a portable mechanism that feeds balls to users, allowing them to practice moves and improve skills without the need for a second player. You can adjust the trajectory, speed and frequency of the balls fed by the machine. Because the Tennis Tutor requires a 12-volt battery for operation, you may need to replace this part after a period of use.
Set the Tennis Tutor on a flat surface. Turn the machine on its side so you can access the battery cover door.
Unscrew each of the screws that hold the panel door onto the side of the Tennis Tutor. Pry this door open with the screwdriver, if necessary. Set the panel aside.
Remove the metal straps obstructing the batteries, using the screwdriver to take out the screws.
Replace each of the batteries with new 12V, 9AH batteries. Install in the exact way the old ones were removed.
Reinstall the parts in reverse order. Turn the Tennis Tutor on to make sure you installed the batteries correctly.
