Introduction
Read this manual carefully to ensure correct steps are done to operate the applicator. This applicator is
designed to apply Harvest Tec buffered propionic acid. Use of alternative products may cause complications.
Including inaccurate readings from the flow meter and damage to all parts. Resulting in the warranty being
void. The applicator can be installed on many square balers with the proper installation kit. Before installing the
unit on the baler, make sure you have the proper installation kit (See the chart below).
*Made for iPad®running the current iOS operating system
*iPad is a trademark of Apple Inc., registered in the U.S. and other countries.
300 Series Applicators with serial number before THS07000 will require the THS to be sent to Harvest
Tec for a required update in order to use the iPad Integration Module (030-6670C).
Hay App version must be at least 2.7.1 (or higher) to operate with the iPad Integration Module (030-6672C)

numbers.
Keep your applicator in proper working condition. Unauthorized modifications to the applicator may impair the

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 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 over filling. 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 at 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.
