Vehicle Controls Figure 10 1. Dipstick 2.
Parking Brake Set the speed limiter as follows: The parking brake is a large lever to the right of the seat. (Fig. 13). Engage the parking brake whenever you plan on leaving the seat to prevent accidental movement of the sprayer. To engage the parking brake, pull up and back on the lever. To disengage, push it forward and down. If the sprayer is parked on a steep grade, apply the parking brake and place blocks at the downhill side of the wheels. 1.
Ignition Switch Note: These tires are different than car tires; they require less pressure to minimize turf compaction and damage. The ignition switch (Fig. 15), used to start and stop the engine, has 3 positions: Stop, Run, and Start. Rotate the key clockwise to the Start position to start the engine and release it to the Run position when started. Rotate the key to the Stop position to stop the engine.
Stopping the Engine Towing the Sprayer 1. Press the brake to stop the sprayer. In case of an emergency, the sprayer can be towed for a short distance. However, we do not recommend this as a standard procedure. 2. Pull the parking brake lever up and back to set it. 3. Move the range selector out of gear into the Neutral position. Warning 4. Turn the ignition key to the Stop position. Towing at excessive speeds could cause a loss of steering control, resulting in personal injury. 5.
1 1 2 3 1 Rate Control Valve 4 This valve, located behind the tank (Fig. 20), controls the amount of fluid that is routed to the booms by directing fluid flow to the booms or the bypass hose to the tank. You can control this valve in two ways: the application rate switch or manually. To control it manually, you need to disconnect the wire connector on the valve, then you can rotate the knob on top of the valve to manually obtain the desired pressure. 3 1 2 Figure 19 1. Boom switches 2.
Tank Drain Knob 2 The tank drain knob is located on top of the tank (Fig. 23). Turn the knob counterclockwise to drain the tank. 1 1 Figure 23 1. Tank drain knob Figure 21 1. Agitation control valve 2. Pressure gauge Tank Cover The tank cover is located in the center of the top of the tank (Fig. 24). To open it, turn off the engine, then turn the front half of the cover to the left and swing it open. You can remove the strainer inside for cleaning.
• App. Rate Spray Pro Monitor Displays the application rate in US gallons per acre (US), liters pre hectare (SI), or US gallons per 1000 sq ft (TURF). The Spray Pro monitor displays and monitors various system performance data such as vehicle speed and application rates. It does not control the application rate. • Total Volume The monitor has an LCD screen that displays the data you select, a selection dial, and 4 buttons for calibrating the monitor (Fig. 25).
Calibrating the Spray Pro Monitor 5. Use the [+] or [–] buttons to select desired units of measure. 6. Press [CAL] until the red light turns off. You can also exit calibration mode by driving the sprayer. The Spray Pro monitor has a calibration mode that allows you to change various settings to customize the display and calibrate the monitor to your needs.
15. When the distance value is displayed, use the [+] or [–] buttons to change it to 500 feet. 12. Press [CAL] until the red light turns off. You can also exit calibration mode by driving the sprayer. 16. When the display begins alternating again, the speed calibration value will have changed; write this number down and save it. This is the calibration value for your sprayer. Calibrating the Speed Sensor The Spray Pro comes approximately calibrated for the speed sensor.
Filling the Spray Tank 12. Adjust the boom bypass valve (Fig. 26) under the boom control valve for the boom you turned off until the pressure reading on the gauge is the same as it was in step 9. Important Ensure that the chemicals you will be using are compatible for use with Viton (see the manufacturer’s label; it should indicate if it is not compatible). Using a chemical that is not compatible with Viton will degrade the o-rings in the sprayer, causing leaks. 1.
5. Turn the Spray Pro selection dial to the Application Rate position and use the application rate switch to achieve the desired rate. 6. Ensure that the agitation control valve is in the On position. 7. Set the pump switch to the On position and use the application rate switch to increase the pressure to a high setting. 6. Set the master boom switch to the On position to begin spraying. Note: When the tank is nearly empty, the agitation may cause foaming in the tank.
