Turf Care Precautions while
Operating in Stationary Modes
Important: Under some conditions, heat from the
engine, radiator, and muffler can potentially damage
grass when operating the sprayer in a stationary mode.
Stationary modes include tank agitation, hand spraying
with a spray gun, or using a walking boom.
Use the following precautions:
•
Avoid stationary spraying when conditions are very hot
and/or dry, as turf can be more stressed during these
periods.
•
Avoid parking on the turf while stationary spraying. Park
on a cart path whenever possible.
•
Minimize the amount of time the machine is left
running over any particular area of turf. Both time and
temperature affect how much the grass may be damaged.
•
Set the engine speed as low as possible to achieve the
desired pressure and flow. This will minimize the heat
generated and the air velocity from the cooling fan.
•
Allow heat to escape upward from the engine
compartment by raising the seat assemblies during
stationary operation rather than being forced out under
the vehicle.

Spraying 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. Once stopped, use the neutral
engine speed control to hold the engine speed up to keep
the agitation running.
•
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.

Selecting a Nozzle

Note: Refer to the nozzle selection guide that is available
through your Authorized Toro Dealer.
The turret bodies can accept up to 3 different nozzles. To
select the desired 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.
Toro recommends using the approved rinse kit for this
machine. Contact your Authorized Toro Dealer for more
information.
Clean the spray system after each spraying session. To
properly clean the spray system:
•
Use three separate rinses.
•
Use the cleaners and neutralizers as recommended by the
chemical manufacturers.
•
Use pure clean water (no cleaners or neutralizers) for the
last rinse.
1. Stop the sprayer, set the parking brake, and turn off
the engine.
2. Locate the tank drain valve on the rear of the machine
(Figure 35).
Note: The valve is to the rear of pump, attached to
the support bracket.
1. Tank drain handle
Open the valve to drain any unused material from the
tank and dispose of it according to local codes and the
material manufacturer's instructions
draining, remove the lynch pin on the bracket securing
