  • Page 55 IV. OPERATING SYSTEMS D. SPRAY SYSTEMS SOLUTION TANK– The GST 20 has a 2000 gallon capacity stainless steel solution tank (fig. 4.52-1). The stainless steel tank has a sparge type agitation system. FIG. 4.52-1 SOLUTION TANK VALVE– The solution tank valve (fig. 4.52-2, item 1) controls the amount of solution coming out of the tank.
  • Page 56 IV. OPERATING SYSTEMS D. SPRAY SYSTEMS SOLUTION PRESSURE GAUGE– The pressure gauge (fig. 4.53- 1) gives you the operator a constant visual display of the amount of solu- tion being applied (measured in PSI). The pressure, as determined by the pulse width modulated control valve, will vary according to ground speed.
  • Page 57 IV. OPERATING SYSTEMS D. SPRAY SYSTEMS SIDE- FILL OPERATION– The solution tank is filled using an operator supplied loading source connected to the side-fill. The side-fill is stationary on the right side of the machine. The rinse connection is located di- rectly above the solution fill connection.
  • Page 58 IV. OPERATING SYSTEMS D. SPRAY SYSTEMS BOOM SOLUTION VALVE SWITCHES– The spray booms are divided into sections that are independently supplied with solution and can therefore be shut off or turned on independently. The electronic boom solution valves are controlled by a row of switches mounted on the right hand console (fig.
  • Page 59 IV. OPERATING SYSTEMS E. OPERATING THE QUICK-ATTACH SYSTEM DETACHING BOOM FROM THE MACHINE FIG. 4.56-1 FOLLOW THESE STEPS: PAGE AND FIGURE REFERENCE 1. Determine where to place the boom once it is off the machine. 2. Lower the boom and secure the boom stands in the down position. 3.
  • Page 60 IV. OPERATING SYSTEMS E. OPERATING THE QUICK-ATTACH SYSTEM FIG. 4.57-1 WHERE TO STORE IT? - When looking for a place to store the boom, there are three important things to keep in mind. First of all, is the ground level? The ground must be pretty level to help prevent tip over. Look at the ground in all directions.
  • Page 61 This is an option and not mandatory on every boom. Do not be alarmed bracket if your boom does not have stands with it. Contact the Hagie Customer Service Department if you would like to have stands. The stands are very simple. They are a brackets attached to the end of the first boom section on both booms and two on the transom.
  • Page 62 IV. OPERATING SYSTEMS E. OPERATING THE QUICK-ATTACH SYSTEM Rear of cab FIG. 4.59-1 OPENING THE BOOM – The booms must be partially open to keep them stable while off the machine . Open the booms so that the stand on the end of the first section is even with the rear of the cab (fig. 4.59-1). This position will allow the booms to sit level with the transom without causing too much stress on the either part.
  • Page 63 Make sure that the solution valve is OFF. There will be a small amount of solution leak out. If it doesn’t stop, or it is excessive, check the valve switch. If the switch is off, contact Hagie Customer Service for repair or parts.
  • Page 64 IV. OPERATING SYSTEMS E. OPERATING THE QUICK-ATTACH SYSTEM CONNECTING BOOM TO THE MACHINE FOLLOW THESE STEPS: PAGE AND FIGURE REFERENCE 1. Square up to the boom. Make sure the quick attach lock assem- blies are open. 2. Pull into the boom slowly. 3.
  • Page 65 If your machine is not equipped with the valves, you will need to call Hagie Customer Service and pur- chase airbag relief valve kits and install them on the front leg as- semblies.
  • Page 66 IV. OPERATING SYSTEMS E. OPERATING THE QUICK-ATTACH SYSTEM LIFT THE BOOM – Lifting the boom will allow the weight of the boom to pull the hooks over the lock pins. Once the hooks are fully over the lock pins, be sure to engage the lock assemblies.

  • Page 67: Calibration

    V. CALIBRATION A. CALIBRATION A. INTRODUCTION INTRODUCTION It is important to apply chemicals as recommended by the manufacturer’s of the product. In order to do so, the spraying system must be properly calibrated. Determine the speed at which the sprayer will be driven while applying the chemicals. To select the best speed, consider the lay of the land, the weather conditions, and the type of chemicals being applied.
  • Page 68 V. CALIBRATION A. INTRODUCTION Example of de-icing solution Rate Cal For the purpose of de-icing solutions, we have chosen to look at the fertilizer nozzles. *This is an example that is based on feedback from our customers, it should not be construed as a recommendation of what type of nozzle you should be using for your spray job.* 1.

    VI. TRANSPORTING A. CRADLING THE BOOMS The booms should always be cradled before traveling, transporting, or parking for an extended period of time. The booms must be folded when cradled. To cradle the booms, fold the boom extensions in, raise the transom, and fold the booms in toward the machine.
  • Page 79 10. A SMV (Slow Moving Vehicle) emblem has been mounted on the sprayer to warn other drivers that one is moving slowly. Keep it properly displayed, unless prohibited by law. Hagie Manufacturing Company does not recommend any form of transportation other than driv- ing the sprayer.

Never operate the engine with the oil level below the “L” (low) mark or above the “H” (high) mark. Wait at least five minutes after shutting off the engine to check the oil level, this allows the oil to drain to the oil pan.
  • Page 87 VII. SERVICE AND MAINTENANCE B. FLUIDS WHEEL HUB OIL BONFIGLIOLI OIL LEVEL– Each wheel hub should maintain a proper oil level at all times. Less than that would limit lubrication and over full would cause overheating and damage.

  • Page 88 VII. SERVICE AND MAINTENANCE B. FLUIDS COOLING SYSTEM COOLANT TYPE– Your cooling system should always be suf- ficiently charged with an adequate mixture of antifreeze and water, regardless of the climate, in order to maintain a broad operating tem- perature range. Your cooling system has been factory charged with an ethylene-glycol based antifreeze.
  • Page 89 VII. SERVICE AND MAINTENANCE B. FLUIDS FUEL TYPE– No. 2 diesel fuel is recommended for the best economy and performance under most operating conditions. In operating conditions under 32° F, use a blend of No. 1 and No. 2 diesel fuel. The addition of No. 1 diesel fuel may cause loss of power and/or fuel economy.
