FM-250 and FM-250S Troubleshooting Guide

Consider this your one-stop-shop for learning what you need to know about your powerfully versatile coaching tool. From turning on your machine to customizing your own drill on your FungoMan remote—we've got you.
Why is my machine disconnecting from the Wireless Controller?
  1. A brownout has occurred. A brownout is where there is a brief interruption in power causing the Wi-Fi system to reset, disconnecting from the machine and forcing the user to reconnect the wireless controller to the Wi-Fi.

  2. The machine is too far away from the wireless controller. Older Wi-Fi systems have known issues of disconnecting when walking into the outfield.
How do I drain the Air Tank?
  1. Power down the machine.
  2. Loosen the air tank drain valve until air dispels from the tank.
  3. Power on the machine.
  4. The compressor should begin “cycling”.

How are balls thrown?

Balls are propelled by the FM-250 using the assistance of an air-powered cylinder to consistently push the ball into the spinning tires. An air compressor keeps the cylinder pressurized by “cycling” after every 15 to 20 balls are fired. The compressor will “cycle” for 1 to 2 minutes or until it fills the air tank to approximately 100 psi. The compressor will then release the air out of the air valve (which sounds like air brakes on a bus). The machine should NOT be powered down during the middle of a compressor “cycle”.

How do I adjust the limit switch on the Throwing Mechanism?

Please view the video in the link below for instructions on how to adjust the ball feed limit switch.

How do I transport the machine?

To load the machine onto a truck bed:

  1. Park the truck on a flat surface. 
  2. Avoid parking on a sloped surface. This will make loading the machine more difficult.
  3. Position the ramps 33" from the outside edge of the ramps. This will ensure that the turf tires are aligned correctly on the ramps.
  4. Push the machine up and onto the truck bed.
  5. Turn the head of the machine all the way to the left.
  6. Push the machine to the back of the bed. The turf tires should rest against the back of the truck bed.
  7. Using ratchet straps, secure the machine as shown below.

Removing the Air Compressor Part 2:


Please follow the instructions below for removing the air compressor.

  1. Drain air tank.
  2. Remove the outer cover of the machine by starting with the rear access cover just above the on/off switch of the machine.
  3. Pay very close attention to this. There are 2 bolts underneath the electrical enclosure, loosen one on the underside of the frame which the enclosure sets on and remove the bolt.
  4. Pull the enclosure slightly out of its normal position to provide enough room to remove the compressor.
    Remove the 4 bolts that attach the compressor to the frame.
  5. Remove the long plastic air tube attached to the compressor by pressing the small black ring forward while pulling the tube out.
  6. Unplug the compressor from the 3 tab power strip.
  7. Remove the compressor from the machine by slowly lifting the compressor, angling it back and forth so as not to pinch any wires or tubes.

How do I test the throwing motor?

The first step in evaluating your throwing wheel motor is to inspect the black bushings (little black plugs located at the end of the motor) and white wire plugs (plugged into the motor wire) to ensure they're tight and secure with no wire damage.

If both are tight and secure with no visible damage to them, proceed to the next step.

The next step is to view the video in the links below for instructions on how to test the throwing motor.

How do I use the manual override button on the Throwing Mechanism?

Please follow the instructions below and in the video to test the Throwing Mechanism using the Manual Override Button:

Performing the manual override test

  1. Manual Override Test:
    With the machine off, drain the Air Compressor
  2. Remove Throwing Mechanism Cover
  3. Identify the Manual ‘Override Button’ on the Throwing Valve
  4. Clear ball out of the “Pinch Point’ area
  5. Power machine on, allow the air compressor to be full (air cycle finished)
  6. Press the override button to test if the Piston is working through the valve in order to fire the Piston
Once you complete the manual override test:
  1. Make sure the machine is turned off.
  2. Drain air compressor.
  3. Take needle nose pliers and manually pull the air cylinder rod out.
  4. Using your hands, push it back in, and then pull it back out. What you're looking for here is to see how smoothly that air cylinder rod is moving. If you experience any resistance, that means that the air cylinder rod is bent and needs to be replaced.


How do I adjust the Throwing Fingers?
Please follow these instructions in order to adjust the throwing fingers:
  1. Turn the machine off
  2. Clear all balls from the pinch point (where the ball is about to be fired)
  3. Using the image below as a reference, please adjust both the bottom and top fingers to be in alignment with the ball chute.

Why does my machine shut down in the middle of a routine and then show me a message saying "Timer Reached"?
Please follow the instructions below to resolve WiFi disconnects with FM App software 4.1.3 and older.
  1. How to properly exit the app: Always press the red "F" at the top left of the screen, when going back to a previous page, or to exit the app completely. 
  2. Locate the white square on the wireless controller next to the Home button. Press the white square and close all apps that are running. This will ensure that you don't have two instances of the app running at the same time.
  3. Execution of a routine: Press base path>routine>play tab>select 1st ball>press throw> then press play to automate. The emphasis is on pressing the "throw" button first, before automating a routine.
