Important If you are using a wettable powder, mix the
powder with a small amount of water to form a slurry
before adding it to the tank
9. Add the remaining water to the tank.
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 (page 23).
1. Set the master boom switch to the Off position.
2. Drive to the location where you will be spraying.
3. Release the boom latches on the boom uprights.
4. Manually rotate the booms into the spray position from
the transport position.
5. Set the individual boom switches, as needed, to the On
positions.
6. Use the application rate switch to achieve the desired
pressure as indicated in the Nozzle Selection Guide
provided with the sprayer.
7. 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.
8. 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.
Note: Return the booms to the transport position and
drive the sprayer to the cleaning area.
Important Always fold up the booms into the
transport position and latch them whenever you move
the sprayer from one spraying area to another or move
to a storage or cleaning area. To move the sprayer,
manually rotate the booms upward to the transport
position, and latch each boom to the boom uprights.
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.
Unclogging a Nozzle
If a nozzle becomes clogged while you are spraying, you
can clean it using a hand spray bottle of water or a
toothbrush.
1. Stop the sprayer on a level surface, stop the engine, and
set the parking brake
2. Set the master boom switch to the Off position and then
set the pump switch to the Off position.
3. Remove the clogged nozzle and clean it using a spray
bottle of water or a toothbrush.
Adjusting a Nozzle
The nozzle bodies can accept up to 3 different nozzles. To
adjust the nozzle:
1. Stop the sprayer on a level surface, stop the engine, and
set the parking brake.
2. Set the master boom switch to the Off position and set
the pump switch to the Off position.
3. Rotate the turret of the nozzles in either direction to the
correct nozzle.
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 water.
4. Rotate the booms into the spray position.
5. Start the engine and move the throttle lever to a higher
idle.
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.
