read on the pressure gauge until it is in the range for the
nozzles you installed on the booms (typically 40 psi).
8. Record the reading on the pressure gauge.
9. Turn off one of the booms using the appropriate boom
switch.
10. Adjust the boom bypass valve (Fig. 24) under the boom

the gauge should remain constant.
Operating the Sprayer
To operate the sprayer you first fill the spray tank, then
apply the solution to the work area, and finally clean the
tank. It is important that you complete all three of these
steps in succession to avoid damaging the sprayer. For
example, do not mix and add chemicals in the spray tank at
night and then spray in the morning. This would lead to
separation of the chemicals and possible damage to the
sprayer components.
Caution
Chemicals are hazardous and can cause personal
injury.
Read the directions on the chemical labels
before handling the chemicals and follow all
manufacturer recommendations and
precautions.
Keep chemicals away from your skin. Should
contact occur, wash the affected area thoroughly
with soap and clean water.
Wear goggles and any other protective
equipment recommended by the chemical
manufacturer.
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, 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 and move the throttle lever to the Spray
position.
6. Set the pump switch to the On position.
7. Set the agitation switch to the On position.
8. 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 small amount of water to form a slurry
before adding it to the tank
9. Add the remaining water to the tank.
