3. Join the chains to the top cross tube with the "S" hooks.Level the outer booms by sliding the boom clamps (Item 8) inor out, as needed, to accomplish this. Tighten the bolts in theboom clamps to hold the clamps in place.

NOTE: The 10 row boom uses (2) spring connectors,eachhaving two ears. Hook a spring to each of the ears, thento the eye bolt.

4. Attach the appropriate hose assemblies onto each of thethree boom sections. The center section has (5) nozzles, with"L" connectors on each end.

5. Assemble the strainers, tips, and caps to the nozzleassemblies, if required.

6. Join the feeder hose from the pumping system to each of theboom sections and secure in place with the appropriate hoseclamps.

TIP SELECTION

Important Note:The tips supplied as standard with this boom assembly areNumber 80015 VP Tips. When you refer to the rate chartsfound in this owners manual, you will note that they have aGPA range of 7.7 to 10.7 GPA (Gallons Per Acre). This istabulated a 5 MPH and from 30 to 60 PSI and 20 inch nozzlespacing. These rates are based on water. Please read thistip selection section carefully before attempting to operateyour boom assembly.

The selection of the proper tips for the boom is determined bythe gallon per acre (GPA) requirement which is specified onthe chemical label. The following characteristics also have adetermining factor and must be considered:

1. Speed of spraying (MPH)2. Boom nozzle spacing (Specified in inches)3. Solution weight and conversion factor (CF)4. Gallons of solution to be sprayed per acre5. Spraying pressure (PSI)

MEASURING TRAVEL SPEED

Measure a test course in the area to be sprayed or in an areawith similar surface conditions. Minimum lengths of 100 and200 feet are recommended for measuring speeds up to 5 and

10 MPH respectively. Determine the time required to travelthe test course. To help insure accuracy, conduct the speedcheck with a loaded sprayer and select the engine throttlesetting and gear that will be used when spraying. Repeat the

above process and average the times that were measured.Use the following equation or the table below to determineground speed.

SPRAYING SOLUTIONS OTHER THAN WATER

Since all the tabulations are based on spraying water, whichweighs 8.34 lbs. per USA gallon, conversion factors must beused when spraying solutions which are heavier or lighter thanwater. To determine the proper size nozzle for the solution tobe sprayed, first multiply the desired GPM or GPA of solutionby the rate conversion factor. Then use the new convertedGPM or GPA rate to select the proper size nozzle.

SPRAYING SOLUTIONS OTHER THAN WATER (Cont.)

Example: Desired application rate is 20 GPA of 28% N.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 supply22.6 GPA of water at the desired pressure.

FLOW RATE

Nozzle flow rate varies with spraying pressure. In general therelationship between GPM and pressure is as follows:

This equation is explained by the illustration above. Simplystated, to double the flow through a nozzle, the pressure mustbe increased four times.

EFFECT OF PRESSURE ON VOLUME

EFFECT OF PRESSURE ON SPRAY ANGLE

Higher pressure not only increases the flow rate of the nozzle,but it also influences the droplet size and the rate of orificewear. As pressure is increased, the droplet size decreasesand the rate of orifice wear is increased.

The values given in the tabulation section of this ownersmanual indicate the most commonly used pressure ranges forthe associated spray tips.

SPRAY ANGLE AND COVERAGE

Depending on the nozzle type and size, the operating pres-sure can have a significant effect on spray angle and qualityof spray distribution. As shown above for an 8002 flat spraytip, lowering the pressure results in a smaller spray angle anda significant reduction in spray coverage.

Tabulations for spray tips are shown in this owners manual arebased on spraying water. Generally, liquids more viscousthan water form relatively smaller spray angles. Whereas,liquids with surface tensions lower than water will producewider spray angles. In situations where the uniformity of spraydistribution is important, be careful to operate your spray tipswithin the proper pressure range.

NOTE: Suggested minimum spray heights for broadcastspraying are based upon nozzles spraying water at therated spray angle.

AFTER SPRAYING

After use fill the sprayer part way with water, start the sprayerand allow clear water to be pumped through the plumbingsystem and out through the spray nozzles.

Refill the tank about half full with plain water and use achemical neutralizer such as Nutra-Sol or equivalent andrepeat cleaning instructions above. Flush the entire sprayerwith the neutralizing agent. Follow the chemical manufacturer’sdisposal instructions of all wash and rinsing water.

Remove tips and screens from the boom. Wash tips thor-oughly with water or cleaning solution (appropriate for chemi-cal used). Blow out orifice, clean and dry. If orifice remainsclogged, clean it with a fine bristle (not wire) brush, or with atooth pick. Do not damage the orifice. Water rinse and dry tipsbefore storing.

WINTER STORAGE

Drain all water out of your sprayer paying special attention topump and valves. These items are especially prone todamage from chemicals and freezing weather.

The sprayer should be winterized before storage bypumping a 50-50 solution of water and anti-freeze throughthe entire plumbing. Proper care and maintenance willprolong the life of the sprayer.
