Changing the Spray Section
Position
Perform the following steps to move the outer spray
sections to the
SPRAY
position:
1.
Park the machine on a level surface.
2.
Use the boom-section lift switches to lower the
outer sections.
Note:
Wait until the outer spray sections reach
the full, extended spray position.
Complete the sprayer job, then perform the following
steps to retract the outer spray sections into the
transport position:
1.
Park the machine on a level surface.
2.
Use the boom-section lift switches to raise the
outer spray sections, until they have moved
completely into boom-section transport cradles
forming the “X” transport position, and the lift
cylinders are fully retracted.
Important:
Release the boom-section lift
switch(es) once the outer spray sections
have reached the desired position. Running
the actuators against the mechanical stops
may damage the lift cylinders and/or other
hydraulic components.

“X” transport position
Important:
To prevent damage to the lift cylinder,
make sure that the actuators are fully retracted
before transporting the machine.
Using the Boom-Section Transport
Cradle
The sprayer is equipped with boom-section transport
cradles that have a unique safety feature. In the
event the spray section accidentally contacts with a
low overhead object while in the transport position,
you can push the spray section(s) out of the transport
cradles. If this occurs, the spray sections come to
rest in a near horizontal position to the rear of the
machine. While this movement will not damage the
spray sections, they should be immediately positioned
into the transport cradle.
Important:
The spray sections can be damaged
by transporting them in any position other
than the “X” transport position using the boom
transport cradle.
To put the outer spray sections back into the transport
cradle, lower the spray section(s) to the spray position
and then raise the spray section(s) back to the
transport position. Make sure that the lift cylinders are
fully retracted to prevent damaging the actuator rod.
Spraying Tips
•
Do not overlap areas where you have previously
sprayed.
•
Watch for plugged nozzles. Replace all worn or
damaged nozzles.
•
Use the master-section switch to stop the spray
flow before stopping the sprayer. Once stopped,
use the neutral engine speed lock to hold the
engine speed up to keep the agitation running.
•
You obtain better results if the sprayer is moving
when you turn the spray sections on.
•
Watch for changes in the application rate that may
indicate that your speed has changed beyond the
range of the nozzles or there is a problem with the
spray system.

Note:
Refer to the nozzle selection guide that is
available through your authorized Toro distributor.
•
If you are operating the sprayer at a slow ground
speed that causes the computer to maintain
too low of a sprayer system pressure for the
application rating of the selected nozzles, the
chemical solution discharges from the nozzle
incorrectly (running or dribbling). Select a sprayer
nozzle with a lower application rate range.
•
If you are operating the sprayer at a high ground
speed that causes the computer to use full sprayer
system pressure and the sprayer pressure is
inadequate to achieve the desired application rate.
To correct the application rate, slow your ground
