Adjusting The Boom Bypass Valves; Operating The Sprayer - Toro 41581 Operator's Manual

Adjusting the Boom Bypass
Valves
Important If you have the Pro Controlt Spray System
installed, the boom bypass valves must be closed. Use the
following adjustment only when you are not using the Pro
Control Spray System.
After you install your booms and nozzles and before using
the sprayer for the first time, adjust the boom bypass valves
so that the pressure and application rate remains the same
for all booms when you turn one or more booms off.
1. Select an open flat area to perform this procedure.
2. Fill the spray tank with clean water.
3. Put the extension booms down, if installed.
4. Set the parking brake and start the engine.
5. Move the throttle lever to the Spray position.
6. Set the pump switch to the On position to start the
pump.
7. Set all 3 boom switches and the master boom switch to
the On position.
8. Use the application rate switch to adjust the pressure as
read on the pressure gauge until it is in the range for the
nozzles you installed on the booms (typically 40 psi).
9. Record the reading on the pressure gauge.
10. Turn off one of the booms using the appropriate boom
switch.
11. Adjust the boom bypass valve (Fig. 27) 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 8.

12. Turn the boom on.
13. Repeat steps 10 through 12 for the other booms.
14. Drive the sprayer at the desired speed while spraying
and turn each boom off individually. The pressure on
the gauge should remain constant.

Operating the Sprayer

To operate the sprayer, 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 3 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 a higher
idle.
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.
