Yes. The Slinger Bag is powered by remote control for your safety and convenience.

Both Launcher and the Oscillator (if included in your package) can only operate via remote control. If you need a replacement please click here.

The main Slinger Bag itself does not oscillate. However, we have created an Oscillator plate on which the Slinger Bag can sit and which allows the Slinger Bag to oscillate. The Oscillator is included in our Champion, Slam, and Player Packs.

Each Slinger Bag allows the user to modify ball speed, ball frequency and ball elevation independently. Ball Speed and Ball Frequency are controlled by the speed and frequency knobs on the front panel of the Slinger Bag. Elevation is controlled by the elevation knob on the right hand side of the bag as you look at it. Please visit page 20 of our User Menu for more detailed information.

All Slinger Bags have a 12 month statutory Limited Warranty (USA) and a 24 month statutory Limited Warranty (EU). Please validate your warranty at www.slingerbag.com/warrantyregistration.

No. Slinger cannot be connected to power when being used. The battery is charged when not in use.

The Slinger Bag is powered by a premium quality Lithium Ion Battery. The ideal charging time for an empty battery is five (5) hours.

Yes. The Slinger Bag has been designed for and tested on all tennis court surfaces.

The Slinger Bag will work with all premium quality standard (yellow) tennis balls including Green and Orange balls. Launcher performance when using Green and Orange Balls maybe reduced. We do not recommend using with Red balls and/or Stage 3 Foam balls.

The amount of top spin generated can be managed by altering the ball speed and elevation angle settings to find a launch sequence that works best for you.

Slinger is also easily moved on the court and we suggest testing varying court placements to find the best mix of placement, speed, angle and ball frequency for your level of play.

No. For safety reasons, the Slinger Bag will only begin launching when the icon with the tennis ball "ON" button is pressed. (First switch the launcher "ON" and then press "ON" on the remote control to activate either the Launcher or the Launcher and the Oscillator when you are in hitting position). If you have lost your remote control, you can purchase a replacement here.

Please follow the below troubleshooting steps:

1. Ensure that you have removed the plastic cover from the magnetic connector at the end of the cable.

2. Ensure that the magnetic connector on both the end of the Oscillator cable and on the Launcher control panel are free from dirt / dust.

3. Press "ON" for both the Launcher and Oscillator button on the remote control.

4. The Oscillator will take 15 seconds to get powered up correctly before oscillation starts.

5. The oscillator has its own motor and will oscillate with only pressing the oscillator button (bottom button on the remote).

If, for any reason, these steps do not work please follow the below instructions:

1. Please remove the battery from the Slinger to assess the battery connection cable. NOTE: The Slinger Bag must be unplugged from the charger before removing the battery for safety reasons.

2. Check the adaptor on the plug to the charger to see that it is securely attached. It will "click" in place when properly inserted. For clear instruction on this step please access our Battery Manual here.

3. Next, be sure that the charger connection that is inserted into the front panel of the Slinger is fully inserted. When charging, the charger will display a RED light. When charging is complete, the light on the charger will turn green.

4. If you are having trouble charging the battery, make sure that the power cable has not become disconnected from the battery.

If none of these steps work, contact our support team at support@slingerbag.com for further assistance.

The power adapter light will turn green when the charge is complete. Please visit page 16 of our User Manual for detailed information.

While up to 144 balls will fit into the ball hopper, we suggest that only 72 balls be placed in while launching for optimal performance. Inside the ball hopper, the mesh walls are held in place by velcro. The velcro should be occasionally checked to ensure that it is held as tightly as is possible to prevent any tennis balls becoming trapped.
