Filling the Spray Tank
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. Stop the sprayer on a level surface, move the range
selector to the Neutral position, stop the engine, and
set the parking brake.
2. Determine the amount of water needed to mix the
amount of chemical you need as prescribed by the
chemical manufacturer.
3. Open the lid on the spray tank.
4. Add 3/4 of the required water to the spray tank using
the anti-siphon fill receptacle.
Important
Always use fresh clean water in the spray
tank. Do not pour concentrate into an empty tank.
5. Start the engine, engage the PTO, and set the hand
throttle if equipped.
6. Turn the agitation control valve to the 9 o'clock
position to start agitation in the tank.
7. Add the proper amount of chemical concentrate to the
tank, as directed by the chemical manufacturer.
Important If you are using a wetable powder, mix the
powder with a a small amount of water to form a slurry
before adding it to the tank
8. Add the remaining water to the tank.
Note: Better agitation can be achieved by decreasing the
application rate setting.
Applying Chemicals
Important In order to ensure that your solution
remains well mixed, use the agitation feature whenever
you have solution in the tank. For agitation to work, the
PTO must be engaged and the engine must be running
above an idle. If you stop the vehicle and need agitation
on, place the shift lever in the Neutral position, set the
parking brake, Engage the PTO, engage the clutch, and set
the hand throttle, if equipped.
Note: This procedure assumes that the PTO is engaged
from the Filling the Spray Tank procedure.
1. Swing the booms into position.
2. Set the master boom switches to the Off position. The
Spray Pro monitor displays "HOLD."
3. Set the individual boom switches, as needed, to the On
positions.
4. Drive to the location where you will be spraying.
5. Turn the Spray Pro selection dial to the Application
Rate position and use the application rate switch to
achieve the desired rate.
Note: The vehicle must be moving for the Spray Pro to
calculate the application rate.
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. In this case, turn the agitation
control valve to the 3 o'clock position to turn it off.
Alternatively, you can use an anti-foaming agent in the
tank.
7. When finished spraying, set the master boom switch to
the Off position to turn off all booms, then disengage
the PTO lever.
Operating Tips
• Do not overlap areas that you have previously sprayed.
• Watch for plugged nozzles. Replace all worn or
damaged nozzles.
• Use the master boom switch to stop the spray flow
before stopping the sprayer. Once stopped, use the
hand throttle, if equipped, to hold the engine speed up
to keep the agitation running.
• You will obtain better results if the sprayer is moving
when you turn the booms on.
• Watch for changes in the application rate that may
indicate that your speed has changed beyond the range
of the nozzles or there is a problem with the spray
system.
Cleaning the Sprayer
Important
You must always empty and clean the
sprayer immediately after each use. Failure to do so may
cause the chemicals to dry or thicken in the lines,
clogging the pump and other components.
1. Stop the sprayer, set the parking brake, place the range
selector in the Neutral position, and turn off the
engine.
2. Use the tank drain knob to drain any unused material
from the tank and dispose of it according to local
codes and the material manufacturer's instructions.
3. Fill the tank with at least 50 US gallons (190 L) of
clean fresh water and close the cover.
Note: You can use a cleaning/neutralizing agent in the
water as needed. On the final rinse, use only clean, clear
water.
4. Start the engine.
