Alternatively, you can use an anti-foaming agent
in the tank.
5.
Use the rate switch to adjust and set a target.

Spraying Tips
•
Do not overlap areas that 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,
place the range selector in the N
EUTRAL
position
and use the neutral engine speed lock 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 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.
Calibrating the Sprayer
Flow
Before using the sprayer for the first time, if you
change the nozzles, or as needed, calibrate the
sprayer flow.
Operator supplied equipment:
Stop watch capable
of measuring ± 1/10 second and a container graduated
in 50 ml (1 fl oz) increments.
Preparing to Calibrate the Sprayer
Flow
1.
Fill the spray tank with clean water.
Note:
Ensure that there is enough water in the
tank to complete the calibration.
2.
Set the parking brake and turn the engine on.
3.
Set the pump switch to the O
N
position, and turn
on the agitation.
4.
Press down on the accelerator pedal until you
reach the maximum engine speed, and toggle
the throttle lock switch to the O
N
position.
Performing a Catch Test
1.
Set all 3 section switches and the master-section
switch to the O
N
position.
2.
Turn the supervisor (rate-lockout) switch to the
U
NLOCK
position.
3.
Prepare to perform a catch test using the
graduated container.
4.
Start at 2.75 bar (40 psi) and use the
application-rate switch to adjust the spray
pressure so a catch test yields the amounts
listed in the table below.
Note:
Repeat the test 3 times and use the
average.
