SPRAY OPERATION
SPRAY OPERATION (After Proper Setup and Calibration)
1. Add 1 /
2
the amount of water required for the spray operation to tank using air gap filler.
2. Start engine, set engine speed below 2000 RPM, and engage pump after taking all previously described
safety and operation precautions.
3. Open agitator valve.
4. Add chemicals (taking all precautions described in this manual and by the chemical manufacturer).
a. Liquids may be poured directly into tank.
b. Wettable powder chemicals must be pre-mixed with water in a container to form a slurry. The mixture
is then added to the tank through the fillwell strainer.
c. Chemical in soluble packs are place into the fillwell strainer basket and dissolved by adding water
through the basket.
The balance of the water required for the spray operation is added to the tank through the fillwell strainer,
using the air gap filler. This will wash any undissolved chemical into the tank.
5. Transport to sprayer site with and agitator operating.
6. Set Engine speed between 2000-3200 RPM.
7. (Optional) Engage ground speed control.
8. Obtain desired spraying speed before activating spray with switches on spray control console.
9. The master boom switch, located on the left floorboard is used to override the master switch on the
computer console of the spray systems. By pushing down it will turn on/off the booms. For 834 Systems
the Master Switch on the computer must be on for the master boom control switch to work. For the 440
System the Master Switch on the computer must be off for the master boom control switch to work.
Review the capacity of nozzles being used. Total capacity of all nozzles plus agitation
system must not exceed pumping system capabilities refer to Spraying Procedure section of
this manual. FLUSH PUMP AFTER USE

To determine the correct performance data for your application, first shut off all flow on discharge side of pump and
determine the shut-off pressure at the pump. Use this Shut-Off pressure to determine which line of data applies.
PROCEDURE TO RE-CALIBRATE FLOWMETER
1. Enter a Meter Cal number of 10 in Meter Cal Button
2. Enter a Total Volume of Calibrating the Pressure Gauge in Total Volume button
3. Switch Off all booms.
4. Remove a boom hose and place in calibrated 5 gallon container
5. Switch on appropriate boom switch and master switch. Pump exactly 10 gallons.
6. Readout in Total Volume is the new Meter Cal Number. Should be within 3% of number stamped on flowmeter.
7. Repeat the procedure several times to ensure accuracy.
8. To verify calibration, fill applicator tank with predetermined amount of measured liquid. DO NOT RELAY ON
GRADUATION NUMBERS ON TANK. Empty tank under normal operation conditions. If the number under total
volume is different from the predetermined amount of measure by more than 3% compete calculation in back of
book.
9. Enter corrected Meter Cal before resuming application.
