OPERATION

Before operating the Spray Star 1750, become familiar with all controls and functions. Also complete all maintenance requirements and read all safety warnings. Knowing the Spray Star 1750 thoroughly, how it operates, and by doing the prescribed maintenance steps, you can expect trouble free operation for years to come.

SAFETY

Safety needs to always be the concern of an operator of a moving vehicle or any machine with moving parts.

1. Keep all shields and guards in place.

2. Keep the parking brake engaged any time the operator is away from the vehicle or whenever service is performed.

3. Always wear the necessary protective clothing and equipment.

4. Turn engine off when refueling or performing maintenance not specifically requiring engine power.

DAILY CHECKLIST

1. Check the engine oil level. Add as needed. DO NOT OVERFILL. Refer to engine owner's manual for oil grade and procedure.

2. Tire pressure should be 20 psi (1.4 bar) maximum.

3. Inspect the electrical system and battery cables for loose connections or frayed wiring. Replace any faulty equipment or tighten if loose.

10

OPERATION

Before using the Spray Star, the operator and spray technician must familiarize themselves with all of the information on chemical spraying contained in the Turf Spray Guide.

All testing and calibrating of sprayers is to be done with water, not chemicals. This insures the safety to all involved in performing the calibration operation. Only after all calibration procedures are completed should chemical be added to the sprayer.

TOWING UNIT

When it is necessary to move the Spray Star 1750 without the engine running, the bypass valve located on the back of the hydrostatic pump must be "open" by turning it

1

/

4

turn to open. The valve is located on the bottom of the pump. An

"open" valve allows fluid to pass through the wheels freely. When normal driven operation is desired, valve should be

"closed" by turning it clockwise. Failure to "close" the valve with engine running means no power to wheels.

HILLSIDE OPERATION

Do NOT stop or start suddenly on any slope. Be especially cautious when changing direction. Do NOT operate on slopes greater than 10°.

BATTERY

Batteries normally produce explosive gases which can cause personal injury. Do not allow flames, sparks or any ignited object to come near the battery. When charging or working near battery, always shield your eyes and always provide proper ventilation.

Battery cable should be disconnected before using “Fast Charge”.

Charge battery at 15 amps for 10 minutes or 7 amps for 30 minutes. Do not exceed the recommended charging rate. If electrolyte starts boiling over, decrease charging.

Always remove grounded (-) battery clamp first and replace it last. Avoid hazards by:

1.

Filling batteries in well-ventilated areas.

2.

Wear eye protection and rubber gloves.

3.

Avoid breathing fumes when electrolyte is added.

4.

Avoid spilling or dripping electrolyte.

Battery Electrolyte is an acidic solution and should be handled with care. If electrolyte is splashed on any part of your body, flush all contact areas immediately with liberal amounts of water. Get medical attention immediately.

JUMP STARTING

Use of booster battery and jumper cables. Particular care should be used when connecting a booster battery. Use proper polarity in order to prevent sparks.

To jump start (negative grounded battery):

1.

Shield eyes.

2.

Connect ends of one cable to positive (+) terminals of each battery, first (A) then (B).

3.

Connect one end of other cable to negative (-) terminal of

"good" battery (C).

4.

Connect other end of cable (D) to engine block on unit being started (NOT to negative (-) terminal of battery)

To prevent damage to other electrical components on unit being started, make certain that engine is at idle speed before disconnecting jumper cables.

OPERATION (CONTINUED)

SPRAYER VALVE SETTINGS AND SPRAY TANK AGITATION

The gate valve on the suction side of the pump, between the tank and the pump must be open before pump is engaged. Close this valve only when necessary to clean the filter with spray material in the spray tank.

There is one manual flow control valve on the discharge side of the spray system. This valve controls the agitator. This valve may be opened as much as necessary to provide hydraulic agitation through the quadrajet agitator in the tank bottom. This valve may be partially closed to prevent or reduce foam buildup from the spray materials inside the tank. When the liquid level in the spray tank reaches a certain level (usually 1-25 gallons

(3.8-95 Liters) depending on terrain and other conditions) it may be necessary to close the valve in the agitator line in order to prevent loss of suction prime.

If your Spray Star is fitted with a hose reel, there is a second ball valve on the discharge system to supply material to the hose reel.

The Quadrajet agitation system operates with four venturi jets in the tank bottom. These jets have replaceable orifice discs which discharge the following amounts of spay material.

You can change orifice disc sizes to enhance spray system performance. Smaller discs reduce amount of agitation (desirable in some foaming materials) and make more dischargeable liquid available for nozzles. Larger (or none) discs increase amount of agitation and make less dischargeable liquid available for nozzles.

INITIAL SYSTEM SETUP

1. Fill tank with water only.

2. Place Master On/Off switch to On, Boom On/Off switches to Off, and open tank shut-off valves.

3. With Pump not running, fully open main line hand valve and totally close agitator line hand valve.

4. Verify that each boom solenoid valve operates by operating Boom On/Off switches and that no nozzles are plugged.

5. Place all Boom On/Off switches On.

6. Hold the Pressure Adjust switch in the increase position until the pressure stops increasing and begins to decrease.

7. Adjust agitator line hand valve for desired agitation.

8. Close the main line hand valve, if necessary, to set the maximum desired operating pressure. (The maximum pressure should be approximately 10 psi (69 kPA), above the normal spraying pressure.)

9. Hold the Pressure Adjust switch in the decrease position until the pressure stops decreasing and begins to increase. If desired minimum pressure cannot be obtained, install larger bypass hose.

10. Verify the desired maximum pressure of the sprayer system by repeating step 6.

CONSOLE FEATURES

A. Master Boom Switch - Activates or stops boom spraying.

B. Individual Boom Switches - Used to activate any of up to 3 booms on a sprayer.

C. PSI Gauge - Indicates the pressure of fluid in the system.

D. Pressure Switch - Used to activate the motorized control valve

E. Fuse Holder - The fuse holder holds one 15 Amp fuse.

CALIBRATING THE PRESSURE GAUGE

The pressure tap on the Raven Sprayer Control system is located away from the nozzles, thus, there can be a pressure difference between nozzle pressure and gauge pressure at the console. Therefore, for best results, Raven recommends the following procedure:

1.

When the sprayer is ready and the tank is filled with water (No chemicals at this time), attach an accurate pressure gauge to a nozzle in place of the spray tip.

2.

Start up the pump, turn on the electric shut-off valves and adjust the pressure control valve so that the desired pressure is maintained on the gauge at the nozzle.

3.

Because of pressure drops through the system, the pressure shown on the gauge in the console may read slightly higher than the gauge at the nozzle. Use this console pressure reading as your reference point for maintaining the desired pressure at the nozzle.

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 MOLDED TANK. Empty tank under normal operatin conditions. If the number under totla 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 resumin application.

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 detemine the shut-off pressure at the pump. Use this Shut-Off pressure to determine which line of data applies.

SPRAY OPERATION

One of the most common causes for faulty-pump performance is corrosion inside the pump. Flush the pump and entire system with a solution that will chemically neutralize the liquid pumped. Mix according to manufacturer’s directions. This will dissolve most residue remaining in the pump, leaving the inside of the pump clean for the next use.

TO PREVENT CORROSION

After cleaning the pump as directed, flush it with a permanent type automobile antifreeze (Prestone, Zerex, etc.) containing a rust inhibitor. Use a 50% solution that is, half antifreeze and half water. Then coat the interior of the pump with a substance which will prevent corrosion such as Fluid Film or WD40. If unit will not be used for an extended period of time, disconnect hoses into and out of the pump, seal openings to the pump with caps or tape. Dispose of fluids according to all federal, state and local regulations.

All chemicals and chemical residue must be removed after each use. Dispose of fluids and residue according to all federal, state and local regulations.

SPRAYER CLEANING

Empty tank and clean unit thoroughly after each use following these instructions:

1. Remove coupling and rinse inside of tank thoroughly with clean water, replace coupling.

2. Fill tank ten percent full with clean water, start pump and discharge water through spray hose or spray boom (with nozzles removed), until empty.

3. Remove drain coupling again and rinse tank interior thoroughly.

4. Rinse exterior of sprayer thoroughly with clean water.

5. Remove bowl from sprayer filter (on operators left hand side of the spray tank). Remove stainless steel screen. Wash bowl and screen thoroughly. Apply thin layer of petroleum jelly to O-ring or gasket. Replace screen and bowl, taking care to position O-ring or gasket properly. Hand tighten.

MANUAL HOSE REEL

Located at the back of the Spray Star behind the tank. Open the ball valve located near the pump to allow fluid to flow into the hose reel. Place the lockout pin in the unlocked position by pulling and turning it half a turn, this will allow you to pull out additional hose or to use the handle and wind up the hose. To prevent movement during transport or storage place the lockout pin in the locked position.

ELECTRIC HOSE REEL

Located at the back of the Spray Star behind the tank. Open the ball valve located near the pump to allow fluid to flow into the hose reel. To unwind hose just pull on the hose to get the desired amount. To wind up the hose make sure the toggle switch is in the ON position, push the momentary push button switch until you have reeled in the amount of hose desire. Turn off the safety switch when not in use.

FOAM MARKER

Located to the right of the control panel. Use lever on compressor to designate which boom is to be used to dispense foam. Use dial located on the foamer to adjust pressure for the amount of foam that will be dispensed.

Switch on the compressor also turns foamer on or off.

SPRAYING INTRODUCTION

This section is intended to offer practical guidelines for the distribution of liquid chemicals over an area of turfgrass such as golf courses, park land, school grounds and lawns. SMITHCO makes no representation as to the suitability of any technique or product for any particular situation. This section is suitable for self-propelled spray vehicles or sprayers mounted onto vehicles.

Boom Spraying is the most effective, accurate and efficient method of applying chemicals to large turf areas. It may be done by means of:

• A dedicated spray vehicle

• A sprayer mounted upon a utility vehicle

Sprayers are typically equipped with wide spray booms. Generally these booms are between 15 feet (4.5 m) and 20 feet (6 m) in width. They are divided into three sections, with hinges that permit the long outer sections to automatically move out of the way and reset if an obstacle such as a tree or fence is in you path.

To minimize the chance for missed areas or double application use a device to mark the outside boundaries of each spray swath. Foam markers and dye markers are advisable.

TURF MANAGEMENT

Turf management chemicals are made for four general purposes:

1. Fungicides: Prevent or cure fungus on turfgrass. They are made in 2 general types:

• Systemic - Chemicals enter the plant system and protect or cure it of, fungus.

• Contact - Kills fungus with which it comes into contact.

2. Insecticides: Eliminate damaging insects and worms (such as grubs, beetles, ants, etc.)

3. Herbicides: Control and eliminate undesirable weeds and grass from turf areas and non-turf areas such as bunkers, trails, fences, etc.

4. Nutrients & Fertilizer: Promote growth, beauty and color in turfgrass.

Some materials have to be applied so that they get into the soil below the plant leaves, This is called "soil appli-

cation". In order to do this, they are best applied with a large volume of water. They are often then watered-in using the irrigation system. This type of chemical material includes systemic chemicals and chemicals designed to destroy pests which live in the thatch and the soil.

Other materials must be applied to reach a problem that is present on the plant leaves. This is called “Foliar

Application” and requires a lower volume of water. Instead of irrigation water, these materials are further activated by dry air and sunshine. They include contact fungicide and many herbicides.

The user of sprayers and chemicals must follow the directions provided with the spray material. It is the only way to insure safe and effective results. It provides information on how much chemical and how much water is to be applied to the area to be sprayed.

Though there are many types and sizes of nozzles, two specific types have proven most successful in turfgrass management.

• The first type is target-directed. It sprays material in a direct line downwards to the target turfgrass.

These are flat fan nozzles, commonly referred to as TeeJet nozzles. They are available in a wide variety of sizes for any required discharge volume rate. They are the best for many contact or foliar applied pesticides. They are spaced either 10" (25 cm) or 20" (51 cm) apart and overlap one another by about

1

/

3

.

• The second type useful in turf management are broadcast type nozzles. They are commonly referred to as raindrop or floodjet nozzles. They spray a hollow-cone shaped pattern of much larger droplets which fall quickly to the turf under their own weight. They are best for systemic pesticides or any material requiring a large volume of water for soil application. The larger droplets are not as subject to drift from wind and are a safer, more environmentally friendly choice in many situations.

16

HOSE & HANDGUN SPRAYING

A handgun (hand-nozzle or hand-lance) is used to control and direct the spray pattern to the ground, shrub or tree. They must be constructed of long lasting and noncorrosive materials such as brass, stainless or aluminum.

The handgun fits to a hose of any length from the sprayer allowing operator mobility. The hose should be as short as possible while still permitting operator mobility.

Liquid looses pressure due to friction as it travels through the hose, 1-3 psi (0.07-0.21 bar) for each foot (30 cm) of hose. For most operations

/

2

" (1.25 cm) inside diameter hose is adequate. Trees over 40 ft (12 m) high require

3

/

4

" (2 cm) inside diameter hose and a sprayer pump capable of delivering a volume of at least 20 gpm

(75 lpm) and a pressure of at least 400 psi (28 bar).

NOZZLES

Always be alert to the possibility of a plugged or damaged nozzles. Serious misapplications may result. Check nozzle output periodically.

Modern nozzles use spring and diaphragm check valves to insure positive cutoff of chemicals without drip.

Snap-on caps make replacing and cleaning nozzles, quick, easy and fool proof with proper reinstallation.

An operator can see at a glance if all nozzles are the same size by the color code.

3 FUNCTIONS FOR A SPRAY BOOM NOZZLE

1. Regulating the flow is done through size of the orifice (opening) within the nozzle. All nozzles, regardless of type, have some point within them that regulates the flow of liquid. Obviously, the larger the opening the greater the rate of flow volume. Volume is expressed in Gallons Per Minute (gpm) or Liters Per Minute

(lpm). Do not confuse the term volume with application rate, which will be covered later.

As pressure increases, the flow volume in a given nozzle also increases. For example, an average size nozzle which discharges 0.52 gpm (1.4 lpm) at 30 psi (2 bar), will discharge 0.73 gpm (2 lpm) at 60 psi

(4 bar). In this example, an increase in pressure of 100% has caused an increase in discharge of 40%.

Some nozzles deliver a small volume (for example: 0.2 gpm (0.75 lpm)). Some nozzles deliver a relatively large volume (for example: 1.5 gpm (5.7 lpm)), or 7 1 /

2

times as much as the smaller nozzle in this example.

The amount of material (volume) to be applied is determined by the effect the chemical has on the turf.

2. The nozzle on a sprayer is to form the liquid into droplets. The size of the droplet is determined by two factors design and system pressure (psi/bar).

Particular applications are done best by big droplets such as systemic fungicides, insecticides and some herbicides in order to reduce drift. Other applications require small droplets like contact fungicides and some herbicides. Again, this is determined by whether the chemical is foliar applied or soil applied. Large droplets for soil applied material, small droplets for foliar applied materials that evenly cover the plant better.

Pressure also affects droplet size. More pressure at the same nozzle produces smaller droplets, more subject to drift. The general rule on pressure is to use the lowest pressure possible with just enough to form adequate spray nozzle patterns.

17

NOZZLES (CONTINUED)

3. Disperse the material in a specific pattern that will insure even distribution of chemical across the swath covered by the boom.

As shown (to the right) the pattern formed by flat fan (TeeJet) nozzles would show most liquid concentrated at the center, then tapering off where it begins to overlap with the next nozzle-approximately

1

/

3

. The pattern of liquid dispersed by the hollow-cone is more even across its width. Each nozzle overlaps the adjoining nozzle by 100%.

That is to say the area covered by each nozzle extends to the center of the two nozzles on either side.

In order to properly develop their spray pattern, each nozzle must be the proper distance from the next nozzle (spacing) and the proper height above the ground.

NOZZLE SCREENS (STRAINERS)

Smaller nozzles require nozzle screens or strainers to prevent clogging.

• Teejet type nozzles size 8001 and 80015 require 100 mesh screens.

• Teejet type nozzles from size 8002 through 8008 require 50 mesh screens.

• Turbo TurfJet Nozzles Size 1/4 TTJ02-VS and larger do not require strainers.

• Turbo Floodjet Nozzles TF-VS2 through TF-VS3 require 50 mesh screens.

• Turbo Floodjet Nozzles TF-VS4 and larger do not require screens.

SPACING

Turf spray nozzles are normally 20" (51 cm) apart. Some cases 40" (101 cm), depending on the type of spray boom and type of area to be sprayed.

Very fine, level areas (golf greens and tees, bowling lawns, tennis courts, etc.) may be sprayed with nozzles spaced every 10" (25 cm).

BOOM HEIGHT

Height is very important in permitting spray nozzles to develop their proper spray pattern. If nozzles are too high, excessive overlap develops. If nozzles are too low, there is not enough overlapping of nozzle spray patterns.

Improper nozzle height or spacing prevents proper application of chemical. Some areas are under treated and chemicals are ineffective. Some areas are overtreated with wasted chemical and possible turf damage.

Operating your sprayer at a desired speed and pressure on a hard, dry surface is a good method of checking spraying consistency. Observe nozzles in operation, observe if the area dries evenly. If there are alternating wet and dry streaks, raise or lower the spray boom. If the wet streaks are directly under the nozzle, the boom is too low. If the wet streaks are between the nozzles, the boom is too high.

18

CALIBRATION INTRODUCTION

Calibrating simply means to adjust a set of variables on the sprayer in order to deliver the desired amount of chemical to a known area of turf.

The job of calibrating the sprayer consists of balancing these variables so that your sprayer delivers the desired application rate. That is, an amount of chemical on a given area. It is expressed as:

Gallons Per Acre (gpa) (1 US gpa = 0.83 UK gpa) or Gallons Per 1,000 Square Feet (gpt) or Liters Per Hectare (lph) (1 US gpa = 9.35 lph)

A number of acceptable methods for calibrating a turf sprayer are widely available. The calibration method chosen must take these variables into account. They must include known ground speed (by measurement or from an accurate speedometer) and nozzle output (gpm or lpm) from a nozzle chart or from actual measurement. The variables are:

PRESSURE

Just as pressure increases the volume discharge rate, it also increases the application rate. Pressure must increase by 4 times in order to double the application rate. Small pressure changes of 10 psi (1.4 bar) or less do not greatly affect performance.

Pressure is established and maintained by a pressure control valve or by a flow control valve located on the sprayer.

NOZZLE CAPACITY (VOLUME)

We have covered the different types of spray patterns of various nozzles and made our selection of type accordingly. We now have to choose a size which will provide the correct application rate.

Sizes are available for all requirements. Consult the nozzle chart in this manual for your nozzle type in order to select the correct size.

TRAVEL SPEED

Increased travel speed decreases the application rate (gpa, gpt or lph). Travel speed must be safe and appropriate for the area to be sprayed.

Unlike pressure changes which have only a minor effect on application rate, ground speed changes have a more major and direct effect. For example: 50% decrease in ground speed means a 100% increase in application rate. If the vehicle does not have an accurate speedometer, correct speed must be determined by timing the sprayer travel over a measured distance. (Refer to the page in this manual titled, “Abbreviations and Conversions”.

To calibrate a sprayer, the user must:

1. Understand the Variables

2. Set those variables using one of the proven methods available.

3. Make a trial run and measure the output (use water, not chemical).

4. Determine the output.

5. Make adjustments to the 3 variables until the output is at the desired level.

This covers the principles of what must be known to prepare a sprayer for operation.

There are other acceptable and proven methods of calibrating a turf sprayer for application.

Other techniques may be more suitable depending on operational needs and technical competence of the operator.

19

THE NOZZLE CHART METHOD OF CALIBRATION

The Nozzle Chart Method is useful when the sprayer nozzles are new or nearly new. It is also the most useful method to employ when the sprayer is equipped with an Electronic Spray Control System. The Electronic Spray

Control System does most of the calibration work, it is up to the operator to select the proper combination of nozzle size and ground speed which will deliver the desired application rate.

The nozzle chart method requires the use of the appropriate nozzle charts which are found in the back of this manual (Nozzle Charts 1 through 8). Nozzle charts for other nozzles are available from the manufacturer.

CALIBRATION STEPS

1. Determine “HOW” your sprayer is to be calibrated from the list of variables below.

a. Nozzle Type (Teejet, Turbo Turf, Turbo Flood) b. Spacing (10" (25 cm) or 20" (51 cm) or 30" (76 cm)) c. Expression of Application Rate (gpa or gpt or lph)

The answers to these three questions will direct you to the appropriate nozzle chart for your application.

The correct nozzle chart MUST be used.

2. Determine the Desired Application Rate.

This is determined from the information on chemical labels or other technical information available from a variety of sources.

3. Determine an Acceptable Ground Speed.

Conditions over which the sprayer will operate generally dictate the appropriate ground speed. Within the limits of practicality and efficiency, spraying should generally be done at lowest possible speed. This increases operator safety and contributes to more precise application of chemicals. For example, golf greens and tees and hill areas would generally be sprayed in the range of 2 1 /

2

to 3 1 /

2

mph (4-6 kph).

Larger, open and more level areas such as golf fairways and park or school grounds would be sprayed at

4 1 /

2

to 6 mph (7-10 kph).

The vehicle which carries or tows the sprayer should be equipped with a precise low-speed speedometer.

If it is not, exact ground speed at a given engine speed must be determined by timing the travel of the sprayer over a measured distance.

4. Determine Nozzle Size.

Refer to the appropriate nozzle chart in the back of this manual for your nozzle TYPE (the type of nozzle you have or type you wish to use), nozzle SPACING and CALIBRATION TYPE (gpm, gpt or lph).

You will note from the chart, that application rates from any given nozzle decrease as the ground speed increases. In other words, the faster you drive, the less material you are applying.

Application rates are shown in the columns to the right of the charts. Once the desired application rate is decided upon, it should be located, as nearly as possible in one of these columns on the appropriate chart for your operation. It could well be that the approximate rate desired would be obtained from the nozzles already installed in the boom. If this is not possible, then nozzles will need to be changed.

When selecting a new nozzle size refer to the “Discharge Rate Column” on the nozzle charts. The Discharge Rate (gpm or lpm) multiplied by the number of nozzles should not exceed 75% of the actual discharge volume of the sprayer pump. [i.e., if you need to use nozzles which discharge 0.8 gpm (3.0 lpm), and the spray boom is equipped with 12 nozzles, the sprayer pump would have to produce an actual discharge volume of 13 gpm (49 lpm) in order to properly supply these nozzles.] If the collective volume of the spray boom nozzles exceeds the actual discharge volume of the pump, inadequate pressure and poor nozzle distribution patterns may result.

Once nozzle type and size have been determined, those nozzles are installed in the sprayer boom.

Nozzles should be expected to be replaced after 15-20 hours of actual sprayer operation. After nozzles are installed, make trial application of water over a known area to check application rate.

20

THE NOZZLE CHART METHOD OF CALIBRATION

5. For Sprayer with Electronic Spray Control Systems.

On sprayers equipped with Electronic Spray Control Systems such as those manufactured by Raven Ind.,

Micro-Trak Co. and Dickey-John Co., it is still important to select the right type and size of nozzle for the required operation. Electronic Spray Control Systems cannot function properly if the nozzles are not capable of delivering the programmed (desired) application rate. Nozzles which are too large will not develop adequate pressure or satisfactory spray patterns. Nozzles which are too small will not allow the discharge of spray material at the programmed application rate.

Further, when calibrating sprayers which are equipped with Electronic Spray Control Systems, care must be taken to use the mode of operation on the Spray Control System (Gallons per acre “US” Mode);

Gallons per 1,000 Square Feet (“Turf” Mode); or Liters per Hectare (Standard International Model), which corresponds with the nozzle calibration charts (gpa, gpt or lph).

6. Using the Nozzle Charts.

Select the correct chart based on your nozzle type, nozzle spacing and desired expression of application rate (gpa, gpt or lph). If the desired operating speed is not found on the nozzle chart, it is simple to determine application rate at different speeds by estimating from the known facts.

Example 1: If the desired speed is 2

1

/

2

MPH (4 kph) on a sprayer using TurfJet nozzles (Chart 5). The average between the application rates for 2 MPH and 3 MPH may be assumed to be the application rate for 2

1

/

2

MPH.

Example 2: The desired speed is 6 MPH. Use the application rate column for 3 MPH a divide by 2.

7. Converting Nozzle Chart Method to British Gallons.

To convert any of the Gallon Per Acre rates to Imperial Gallons per acre, (Imp gpa) multiply by 0.83. To convert any of the Liter Per Hectare rates to Imperial Gallons Per Hectare (Imp GPH), multiply by 0.22.

8. Checking the Actual Application Rate.

After the combination of ground speed, nozzle size and operating pressure has been selected, the sprayer should be operated with water only to determine if the target application rate is achieved.

THE “128” METHOD OF BOOM SPRAYER CALIBRATION

The “128” Method is useful for calibrating sprayers and also for checking the calibration of sprayer calibrated by the Nozzle Chart Method and sprayers using Electronic Spray Control Systems. The “128” is based on a convenient mathematical relationship that exists between US Gallons, liquid ounces and acres.

An ounce is 1/128th of a (US) gallon. If an area which was “1/128th of an acre” could be found, the number of ounces applied to that small area would be equal to the number of gallons applied to the acre Thus, no mathematical computations would be required.

To determine an area which is 1/128 of an acre:

• On nozzles with 20 inch (51 cm) spacing, measure off a distance of 204 ft (62 meters). Mark a “START” and a “STOP” line. The rectangle formed by this distance and the spraying width of one nozzle 20" (51 cm) is equal to 340 square feet which is equal to 1/128 acre. Therefore, the amount of material applied to this area by one nozzle in OUNCES is the same amount of material applied to an acre in GALLONS

(gpa).

• On nozzles with 10 inch (25 cm) spacing, the measure distance is 408 feet (124 meters).

• On nozzles with 30 inch (76 cm) spacing the measured distance is 136 feet (41 meters).

CALIBRATING FOR APPLICATION

1. Fill the sprayer tank with water. Run the sprayer, inspect it for leaks and make sure all systems function properly.

2. Drive the sprayer through the measured distance discussed above at normal spraying speed, record the travel time required to cover the measured distance in seconds with a stopwatch.

21

THE “128” METHOD OF BOOM SPRAYER CALIBRATION

The carrying or towing vehicle is to be traveling at the desired speed when it crosses the start line of the measured course.

Repeat this procedure and determine the average of the two times.

3. With the sprayer parked, run the sprayer at the required pressure level. Catch the output of each nozzle in a container which is marked or graduated in Ounces for the exact same period of time which it took the sprayer to cover the measured course in step #2. It is necessary to operate the vehicle engine at spraying speed using a hand throttle.

4. Observe the volume of water in the collection bottle. The number of OUNCES collected in the time it takes to cover the marked course. Take the average nozzle output by adding the outputs of each nozzle and then dividing that sum by the number of nozzles.

The NUMBER OF OUNCES collected in the time required to cover the SMALL AREA is equal to the

NUMBER OF GALLONS applied per ACRE. For example: if an average of 40 ounces of water is collected in the time required to cover the 1/128 acre area, the application rate is 40 gallons per acre (gpa).

As a practical matter, if high application rates are desired (above 75 gpa), the measured course length should be reduced by half (i.e. 102 ft (31 m) for 20 inch (52 cm) spaced nozzles). The volume collected (above) is then doubled (multiplied by 2).

AVERAGE OUTPUT (Ounces) = APPLICATION RATE (gpa)

5. Observe individual nozzle output volumes. If an individual nozzle is 10% above or below the average output, check for blockages in the nozzle or in the nozzle strainer. If the nozzle is worn or damaged, replace it.

6. Compare this actual application rate with the recommended rate. If the actual rate is more than 5% higher or lower than the intended rate, adjustments must be made.

7. Minor adjustments in application rate may be made by increasing or decreasing the spraying pressure.

Lowering spraying pressure decreases application rate. Increasing spraying pressure increases application rate. This procedure normally does not apply to spray systems controlled by an Electronic Spray

Control System, which governs flow rate.

8. Adjustments in application rate may be made by increasing or decreasing the travel speed of the sprayer if conditions permit. Slower speeds increase application rate. Faster speeds decrease application rate.

9. Nozzle sizes can be changed to provide the correct application rate. Refer to the nozzle charts in this book for the desired nozzle type.

10. Re-calibrate the sprayer (steps 2-6) after any adjustments are made.

As previously discussed, there are other acceptable methods of Turf Sprayer Calibration. Chemical suppliers, Agricultural Extension Agents, Universities and consultants of various types offer helpful advice on this subject. Technical catalogues are available from nozzle manufacturers.

TRANSFERRING THE “128” METHOD INTO METRIC (LITERS PER HECTARE)

The same steps are used that are used when calibrating in gallons per acre. First a relationship between a measurable amount (milliliters) and the calibration amount (liter) is determined. That ratio is 1:1000.

Now an area which is 1/1000th of a hectare must be measured.

On spray booms with 51 cm (20 inch) spacing, mark off an area which is 20 meters (65.6 feet) long . The area formed by that length and the width of one spray nozzle (20 meters by 0.5 meters) is 10 square meters which is

1/1000 of a hectare. Therefore, the amount of spray material applied to this small area in milliliters is equal to the amount applied to one hectare in liters.

Then, follow the remaining steps 2-10, substituting milliliters for ounces, liters for gallons, square meters for square feet and hectares for acres.

AVERAGE OUTPUT (Milliliters) = APPLICATION RATE (LITERS/HECTARE)

LIMITED WARRANTY

SMITHCO warrants this product to be free from defects in material and workmanship under normal use for one year from the date of purchase by the original user. (60 days if product is used for rental purposes.) All warranty claims must be handled through a SMITHCO authorized dealer or by

SMITHCO, INC. All transportation charges must be paid by the purchaser.

There is no further express warranty. All implied warranties, including those of merchantability and fitness for a particular purpose, are limited to one year, (60 days if product is used for rental purposes) from the date of purchase by the original user, and to the extent permitted by law any and all implied warranties are excluded and disclaimed after the expiration of such period.

All incidental and consequential damages, including pickup and delivery of the unit, communication, mileage charges and/or rental of a replacement unit during repair, are not covered under this warranty, nor is any loss of income and/or other loss resulting from the failure of the product to function due to a warranty defect.

The following items are not covered under the SMITHCO warranty, and are warranted by their respective manufacturer.

(a) Engine and engine parts, including starters, generators, alternators and filters.

(b) Transaxle, differentials, gear boxes and mechanical pumps.

(c) Hydrostatic transmissions, hydraulic pumps and motors.

(d) Batteries.

(e) Wheels and tires.

A copy of the warranty for the above items is furnished if necessary with each SMITHCO product.

Some states do not allow limitations on how long an implied warranty lasts, or the exclusion or limitations of incidental or consequential damages, so the above limitations or exclusions may not apply to you. This warranty gives you specific legal rights and you may also have other rights, which may vary from state to state.

Federal law now requires disclosure of the warranty which applies to this product prior to the sale to a customer. Please leave this statement attached to the product and allow the buyer to remove it after purchase.
