854 Sprayer Control

Before spraying, check all connections related to the
Sprayer Control System. Particular attention should
be given to the sensors to ensure the console
received strong, uninterrupted signals. Make sure
connections are made and the sensors are working
properly.
IMPORTANT! When working around a sprayer or
chemicals, always wear protective clothing
and eye wear.
NOTE: It is recommended that the entire sprayer
be calibrated to prepare the machine for
operation and to diagnose spray tip wear.
Worn tips can contribute to costly chemical
waste and inaccurate spraying, regardless
of the use of a sprayer control. Calibration is
necessary to obtain the benefits associated
with a computerized sprayer control.
Partially fill the sprayer tank with water to flush the
system. Perform a visual inspection of the spray
tips to ensure all tips are delivering a good spray
pattern.
• Set the Master Boom Switch to the “Off”
position.
• Make sure the tank shutoff valve is open.
• Start the vehicle’s engine, engage the pump,
and set the RPM to that being used when
spraying.
• Turn the 854 on by pressing the
PROGRAM key.
• Ensure that the preset reference flow arrow
matches the set of tips being used.
• Verify that the 854 recognizes the simulated
speed. If the simulated speed has been
disabled (due to vehicle movement)
activate the simulated speed by turning the
Master Boom Switch “On” and pressing
the PROGRAM and MINUS keys
simultaneously for a Low simulated speed,
or by pressing the PROGRAM and
PLUS keys simultaneously for a High
simulated speed.
• Turn each individual spray boom section “On”.

position.
• Adjust the pressure with the PLUS or
MINUS keys. The pressure should increase
when the PLUS key is pressed and
decrease when the MINUS is pressed.
Check the sprayer to ensure it is activated. Visually
ensure spray tip performance.
• Press the AUTO/MAN key so that the
red LED indicates “AUTO” mode. The
control console should regulate to the target
application rate for the simulated speed.
• While spraying, press the PROGRAM
and PLUS keys simultaneously for a High
simulated speed. The 854 should increase
