Assembly
Calibration
1. Mount the upright angles to the inside of the mounts on the
carrier, using the supplied bolts/nuts. Attach the backrack to the
upright angles using the square u-bolts & nuts. NOTE: The
backrack can be mounted in either a high or low position and the
uprights can be adjusted for desired height. Attach the UBrackets as shown in the exploded view drawing.
2. Loosen the eye-bolts and remove the 7" hinge bolt(s). Line up
the outer booms and reassemble the hinge bolt through the outer
boom yoke, the hinge casting, and the spring connector. Tighten
the eye-bolt until the spring is at the desired tension. Lock the
eye-bolt in place with the inner whiz flange locknut. The 8-Row
booms use extensions on the outer booms. Bolt on the boom
extensions using the bolts/nuts provided. (see exploded view
drawing)
3. Hook an end of each boom chain on an "S" hook attached to
the top bar tube. Place a slide clamp onto each outer boom.
Place the other end of the boom chain between the ears of the
slide clamp and secure with the bolt/nut per the exploded view.
Level the outer booms by moving the slide clamps in or out as
needed. Tighten the bolts in the slide clamps to hold the clamps
in place.
4. Attach the appropriate hose assemblies onto each of the three
boom sections. the center section has (5) nozzles with "L"
connectors on each end. Starting at the center, the nozzles
should be placed about 20 inches apart.
5. Join the designated feeder hose to each boom section and
secure in place with hose clamps.
Tip Selection
Important note:
The tips supplied as standard with this boom assembly are
number 8003VP tips. when you refer to the rate charts found in
this owners manual, you will note that they have a GPA range of
15.4 to 22 GPA (Gallons Per Acre). This is tabulated at 5 MPH,
and from 30 to 60 psi and 20 inch nozzle spacing. These rates
are based on water. Please read this tip selection section
carefully before attempting to operate your boom assembly
The selection of proper tips for the boom is determined by the
gallon per acre (GPA) requirement which is specified on the
chemical label. The following characteristics also have a
determining factor and must be considered:
Chemical labels may show application rates in gallons per
acre, gallons per 1000 square feet, or gallons per 100
square feet. You will note that the tip chart shows all 3 of
these rating systems.
Once you know how much you are going to spray, then
determine (from the tip chart) the spraying pressure (PSI),
and the spraying speed (MPH).
Determining the proper speed of the pulling vehicle can be
done by marking off 100, 200, & 300 feet. The speed chart
indicates the number of seconds it takes to travel the
distances. Set the throttle and with a running start, travel the
distances. Adjust the throttle until you travel the distances in
the number of seconds indicated by the speed chart. Once
you have reached the throttle setting needed, mark the
throttle location so you can stop and go again, returning to
the same speed.
Add water and proper amount of chemical to the tank and
drive to the starting place for spraying.
Testing the Sprayer
NOTE:
It is VERY important for you to test your sprayer with
plain water before actual spraying is attempted. This will
enable you to check the sprayer for leaks, without the
possibility of losing any expensive chemicals.
Add water to the tank & drive to the starting place for
spraying. When you are ready to spray, turn the boom valve
to the "on" position. This will start solution spraying from the
tips of the boom. The pressure will decrease slightly when the
boom is spraying. Adjust the pressure by turning the
"ON/OFF" valve lever on the bypass line valve.
Read the operating instructions and Initially begin spraying by
closing the 'bypass' valve (this is the center ON/OFF valve
located at the center port of your manifold assembly) and
opening the boom line valve (this is the 'other' valve on the
manifold). This will enable the air in the line to be eliminated
(purged) through all the tips, while building pressure. When
everything tests all right (no leaks, & good pressure), add the
desired chemicals to the mixture and water combination and
start your spraying operation. Adjust the pressure and spray
as you did in the testing procedure.

Spraying Solutions Other Than Water
Flow Rate
Nozzle flow rate varies with spraying pressure. In general,
the relationship between GPM and pressure is as follows:
This equation is explained by the illustration below. Simply
stated, to double the flow through a nozzle, the pressure be
increased four times.

@ 10 psi @ 40 psi
8002
Since all the tabulations are based on spraying water, which
weighs 8.34 lbs per USA gallon, conversion factors must be
used when spraying solutions which are heavier or lighter than
water. To determine the proper size nozzle for the solution to be
sprayed, first multiply the desired GPM or GPA of solution by
the rate conversion factor. Then use the new converted GPM or
GPA rate to select the proper size nozzle.
Example:
Desired application rate is 20 GPA of 28% Nitrogen.
Determine the correct nozzle size as follows:
GPA (Solution) x Conversion Factor = GPA
20 GPA (28%) x 1.13 = 22.6 GPA (Water)
The applicator should choose a nozzle size that will supply 22.6
GPA of water at the desired pressure.
Miscellaneous Conversion Factors
One Acre = 43,560 square feet = 0.405 Hectacre
One Hectacre = 2.471 Acres
One Gallon Per Acre = 9.35 Liters Per Hectacre
One Mile = 5280 Feet = 1610 Meters = 1.61 Kilometers
One Gallon = 128 Fluid Ounces = 8 Pints = 4 Quarts = 3.79
Liters = 0.83 Imperial Gallons
One Pound Per Square Inch = 0.069 bar. = 6.895 Kilo-Pascals
One Mile Per Hour = 1.609 Kilometers Per Hour
Higher pressure not only increases the flow rate of the nozzle,
but it also influences the droplet size and the rate of orifice
wear. As pressure is increased, the droplet size decreases
and the rate of orifice wear is increased.
The values given in the tabulation section of this owners
manual indicate the most commonly used pressure ranges for
the associated spray tips.

Higher pressure not only increases the flow rate of the
nozzle, but it also influences the droplet size and the rate of
orifice wear. As pressure is increased, the droplet size
decreases, and the rate of orifice wear is increased.
The values given in the tabulation section of this owner's
manual indicate the most commonly used pressure ranges
for the associated spray tips.
Spray Angle and Coverage
Depending on the nozzle type and size, the operating
pressure can have a significant effect on spray angle and
quality of spray distribution. As shown above for an 8002 flat
spray tip, lowering the pressure results in a smaller spray
angle and a significant reduction in spray coverage.
Tabulations for spray tips shown in this owner's manual are
based on spraying water. Generally, liquids more viscous
than water form relatively smaller spray angles. Whereas,
liquids with surface tensions lower than water will produce
wider spray angles. In situations where the uniformity of
spray distribution is important, be careful to operate your
spray tips within the proper pressure range.
NOTE: Suggested minimum spray heights for broadcast
spraying are based upon nozzles spraying water at the
rated spray angle.
