Inkqubo yokuJonga umzobo


Ukufakwa kweMibhobho yamanzi

To most effectively mark the wet spots in any bale, Harvest Tec recommends that the nozzles are mounted directly above or below the Star Wheels. To get the best spray pattern focused directly on the wet spot of the bale the nozzles will need to be approximately 1” above the bale that is being marked. A small notch may need to be cut to increase surface area of the bale being marked.

  1. Once you have the tank and mounting bracket securely fastened to the baler, locate parts A, B, C, D & E pictured below in Figure 1 or 2. Assemble in the following order:
  • Elbow
  • nozzle holder
  • Jonga ivalve
  • reducing bushing
  • tip as pictured below.

Phawula: All parts should be thread taped

  1. Once the nozzle holders are fastened to the balers, route the 3/8” hose to the tips. Make sure to fasten the hose securely but avoid pinching the lines. (Plumbing Diagram pictured in Figure 7)
    1. Keep from routing the hose in the way of moving parts on the baler.
  2. Attach drain hose top hose barb fitting at bottom of the tank. Run the hose to a secure point and attach valve assembly.HARVEST-TEC-740DM-Dye-Sprayer-Marking-System-FIG-4

  1. Install the tip and nozzle holder assemblies in the suggested locations pictured shown below. Use the 1/4” hardware provided to do so.HARVEST-TEC-740DM-Dye-Sprayer-Marking-System-FIG-5
  • Make sure that the tip assemblies (A) are mounted in line with the star wheels (B) so that the system is marking the wet spots of the bale.

Umbuzo oqhelekileyo

Is the marking dye safe for livestock consumption?

  • The DSM uses red-colored, food-grade dye and is safe for all livestock.

How do I bleed the air out of the lines properly?

  • Remove the tips from the check valves that they’re threaded into and press the prime button on the dye marker until the air is pushed out of the lines.

Ukulungisa ingxaki

Ingxaki Isizathu esinokubakho isisombululo
Iingcebiso azitshizi iDayi
  1.    The system is out of the dye.
  2. There is air in the lines, preventing a steady mist from coming from the tips.
  3. Damaged/pinched hose.
  4. The tip is plugged.
  5. Setpoint is set too high
  1.     Check the tank for a solution. If the tank is empty, refill and bleed air from lines.
  2.     Remove the tips from the check valves and using the priming button bleed the air out of the lines.
  3.     Inspect all the hoses making sure the lines are damaged or pinched.
  4.     Removed the tip from the bushing and inspect, clean is necessary.
  5.     Lower the set point level at which the user would like to have the bales marked at.


  1. For winter storage, drain all of the liquid out of the lines and tank, and pump.

Filling Tank & First Time and Annual Startup

Ukuzalisa iTanki
Remove the tank lid from the 3-gallon tank. Make sure the tank is clean and completely empty. Mix the Dye (009-0800) with warm water inside the Dye bottle. Make sure that the the bottle is shaken vigorously so that the dye completely dissolves. Once the solution is mixed, add it to the 3-gallon tank and fill the tank with water.

  • Once the tank has been filled the plumbing lines will need to be primed. With the system turned on and in a paused mode, hold the priming button until all the air is flushed out of the lines and there is a steady stream of liquid coming from each of the tips.

PHAWULA: The system needs to be primed every time the system has run out of dye.

  • You can adjust the moisture content level at which you would like the system to mark the ‘Wet Flakes’ in the bale is made. This can be done by entering ‘Setup’ followed by moisture setup, then adjusting Set Point.


Operating Instructions Automatic Mode or Manual Mode

Auto & Manual mode will automatically mark bales with dye if the moisture dye marking system is turned on and moisture content sensed by the star wheels is above the moisture ‘Set Point’ level that was set by the operator.

  1. The moisture sensed by the star wheels is indicated below. See page 9 for set-up instructions.
