Preparing the Applicator for Operation
After the Applicator has been installed on the baler, follow the below steps to prepare for operating the applicator both safely and correctly.

Filling the tank through the Drain / Fill kit (Model 344, 350 & 351)

Read the label of the product being filled into the tank to determine what individual protective measures need to be taken. Locate the drain/fill line on the baler. Open the cam-couplers (A) and remove the protective plug (B). Insert the male coupler (found on the transfer pump) into the female cam and close the cams (A).
To open the ball valve (C) turn the handle so it is vertical. After the ball valve has been turned on switch the pump to the On position. Monitor the level on the tank visually and shut off the pump before overfilling. Once the pump is turned off, close the ball valve and remove the male coupler. The handle of the ball valve (C) will be horizontal when closed. Reinstall the protective plug and close the cams. The Harvest Tec model 9212 transfer pump is recommended for this process.
Water is recommended for first-time and annual start-up procedures.

Filling the tank through the tank lid opening (Model 344, 345, 350, 351)
Read the label of the product being filled into the tank to determine what individual protective measures need to be taken. Clean the tank lid area and unscrew the lid. Transfer product from the container into the tank.
Water is recommended for first-time and annual start-up procedures.

Operation of the Main Ball Valve

The ball valve should always be closed when the applicator is not being used. The valve should also be closed when any service work is being done to the baler or applicator.
The valve is located next to the pump and by the applicator tank. The arrow below points to the valve.

Connecting the power harness
The power harness that supplies power from the tractor battery to the applicator pump has a disconnect at the hitch. Connect the two together for operation. Always disconnect before servicing the applicator or baler.
WARNING: Stop tractor engine and shift to park, set brakes, and remove key before leaving the tractor.

Common Questions

1. How do I turn the system on/off?
   To turn the system ON open the Hay App, then select the active system for the baler you are using.
   To turn the system OFF click the Main Menu screen. To close the app double-click the home button on the iPad and swipe the app that you would like closed, toward the top of the screen until it is no longer visible. See SHUTTING DOWN THE HAY APP for more details.
2. How to get in the LBS/TON, MC%, and TONS/HR screens?
   In the Main Menu press the SETUP MODE key. From this screen you can change your application rates and how much product is applied. See SETTING UP FOR  INITIAL USE for a detailed explanation of this process.
3. The unit is stuck in the Application Rate screen.
   In the Application Rate screen, level 1 must be less than level 2, and level 2 must be less than level 3. For example, if level 1 is set at 16, level 2 must be set at 17 or higher,  and level 3 must be set higher than level 2.
4. How does OVERRIDE work?
   Override turns on the pump and opens the solenoid for full output. The pump and solenoid will remain at full output until the operator turns the pump off by pressing the OVERRIDE key again.
5. The flow meter reading is more or less than the programmed level set in the box.
   Some variation in flow meter readings compared to the programmed set point is normal due to factory tolerances on the pump motor as well as varying tractor voltages inputted to the control box. The flow meter reading is an accurate measure of how much product is being applied. The set points then will need to be adjusted if you want to attain a different flow meter reading.
6. The moisture content displays “LO” or “HI” all the time.
   When the moisture content display does not change frequently while baling, there is likely a faulty star wheel connection. Initially check inside the white star wheel block, to see if the electronic swivel is in the star wheel shaft and that the star wheel shaft is not coming out of the block. Also, check all star wheel wires and connectors to see if there is a continuity of grounding problem.
7. Should the battery connections be removed before jump-starting or charging a battery?
   Yes. Anytime the tractor will have voltage going up rapidly the connections should be removed.
8. What is the expected battery life of the iPad when baling?
   3.5 hours is the expected amount of time for the battery when continuously baling. Shut off all other applications, wireless internet, and Wi-Fi signals to reduce the number of programs the iPad is running.
   It is recommended to use an accessory outlet charger when operating (not included with the iPad).
   *Note: Not all chargers are designed to charge an iPad, verify before purchasing.
9. What is the max distance for connection between the iPad and the Bluetooth Receiver?
   Pre-2020 applicators were equipped with Bluetooth receivers (030-6672B). The range for the connection will depend on the amount of equipment (tractor, baler, etc.). The max distance will range between 10’–20’.
10. What do the lights on the 030-6672B indicate?
    Pre-2020 applicators were equipped with Bluetooth receivers (030-6672B) and are now equipped with lights to indicate both power and Hay App connection on the Apple iPad.
    Red Light – The Bluetooth receiver has power
    Green Light – The Bluetooth receiver is connected to the Hay App.
