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 pump must
be on and the engine must be running above an idle.
Note: This procedure assumes that the pump is on from the
Filling the Spray Tank procedure.
1. Set the master boom switch to the Off position.
2. Swing the booms into position.
3. Set the individual boom switches, as needed, to the On
positions.
4. Drive to the location where you will be spraying.
5. Use the application rate switch to achieve the desired
pressure as indicated in the Nozzle Selection Guide
provided with the sprayer.
6. Drive at the desired speed and then 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
switch 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 set the pump
switch to the Off position.
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.
You will obtain better results if the sprayer is moving
when you turn the booms on.
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, 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 and move the throttle lever to the Spray
position.
5. Ensure that the agitation control valve is in the On
position.
6. Set the pump switch to the On position and use the
application rate switch to increase the pressure to a high
setting.
7. Set the master boom switch and boom control switches
to the On positions to begin spraying.
8. Allow all of the water in the tank to spray out though
the nozzles.
9. Check the nozzles to ensure that they are all spraying
correctly.
10. Set the master boom switch to the Off position, set the
pump switch to the Off position, and stop the engine.
11. Repeat steps 3 through 10 at least 2 more times to
ensure that the spray system is fully cleaned.
Important
You must always complete this procedure at
least 3 times to ensure that the spray system is fully clean,
preventing damage to the system.
12. Clean the strainer; refer to Cleaning the Suction
Strainer, page 38.
Important
If you used wetable powder chemicals,
clean the strainer after each tank.
13. Using a garden hose, rinse off the outside of the sprayer
with clean water.
14. Remove the nozzles and clean them by hand. Replace
damaged or worn nozzles.
