Step 1: Unboxing and Charging

Carefully unbox your tennis ball machine and check for all parts (machine, charger, remote, manual). Before use, fully charge the machine by plugging it into a power outlet. Charging usually takes 4-6 hours.Depending on the model

Step 2: Loading the Tennis Balls

Once charged, open the hopper and load the balls. Be sure not to exceed the machine’s ball capacity, typically between 30 and 100 balls.

Step 3: Positioning on the Court

Place the machine on a stable surface at your desired position on the court. For baseline drills, position it opposite you.

Step 4: Setting Speed, Spin, and Frequency

Use the control panel or app to adjust ball speed, spin (if available), and feeding frequency. Beginners should start with lower speeds and slower feed rates.

Step 5: Choosing Shot Type

Select from fixed-point, oscillating (for random shots), or lob shots, depending on your training needs.

Step 6: Starting and Adjusting

Turn on the machine and start hitting! Use the remote or app to pause or adjust settings as needed during practice.

Step 7: Ending and Storing

Turn off the machine, unload the balls, and wipe it down after use. Store it in a safe, dry place and recharge it for next time.
