Operating The Booms; Spraying - Toro 41235 Operator's Manual

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.
Important: After filling the tank for the first time, check
the tank straps for any play. Tighten as necessary.
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 tank cover on the spray tank.
The tank cover is located in the center of the top of
the tank (Figure 40). To open it, turn the front half of
the cover counterclockwise and swing it open. You
can remove the strainer inside for cleaning. To seal the
tank, close the cover and rotate the front half clockwise.
1. Tank cover
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 wettable powder,
mix the powder with 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.

Operating the Booms

The boom lift switches on the sprayer control panel allows
you to move the booms between transport position and
Figure 40
2. Anti-siphon fill receptacle
spray position without leaving the Operator's seat. It is
recommended to change boom positions while the machine
is stationary.
To change the boom position:
1. Stop the machine on level ground.
2. Use the boom lift switches to lower booms. Wait until
the booms reach the full, extended spray position.
3. When the booms need to be retracted, stop the sprayer
on level ground.
4. Use the boom lift switches to raise the booms. Raise
the booms until have moved completely into boom
transport cradle forming the "X" transport position
and the boom cylinders are fully retracted.
Important: To prevent damage to the boom
actuator cylinder, make sure the actuators are fully
retracted before transport.
The Boom Transport Cradle
The sprayer is equipped with a boom transport cradle that
has a unique safety feature. In the event of accidental boom
contact with a low overhead object while in the transport
position, the boom(s) can be pushed out of the transport
cradles. If this occurs, the booms will come to rest in a
near horizontal position to the rear of the vehicle. While
the booms will not be damaged due to this movement, they
should be immediately put back into the transport cradle.
Important: The booms can be damaged by transporting
them in any position other than the "X" transport
position using the boom transport cradle.
To put the booms back into the transport cradle, lower the
boom(s) to the spray position, and then raise the boom(s)
back into the transport position. Make sure the boom
cylinders are fully retracted to prevent actuator rod damage.

Spraying

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. Lower the booms into position.
2. Set the master boom switch to the Off position. The
Spray Pro monitor will display "HOLD".
3. Set the individual boom switches, as needed, to the On
positions.
4. Drive to the location where you will be spraying.
