1. Direct exposure to hazardous chemicals can cause serious injury. These chemicals can include lubricants, coolants, paints, adhesives and agricultural chemicals. Material Safety Data Sheets
(M.S.D.S.) are available for all hazardous chemicals which inform the user of specific details including, physical and health hazards, safety procedures, and emergency response techniques.
2. Protective clothing such as rubber gloves, goggles, coveralls and respirator must be worn while handling chemicals. All protective clothing should be kept in excellent condition and cleaned regularly or discarded.
3. If chemicals come in contact with any exposed skin areas, wash immediately with clean water and detergent. Never place nozzle tips or any other components that have been exposed to chemicals to lips to blow out obstructions. Use a soft brush to clean spray nozzles.
4. Dedicate an area to fill, flush, calibrate and decontaminate sprayer where chemicals will not drift or run off to contaminate people, animals, vegetation, water supply, etc. Locate this area where there is no chance of children coming in contact with this residue.
5. Decontaminate equipment used in mixing, transferring and applying chemicals after use. Follow the instructions on the chemical label for the correct procedure required. Wash spray residue from outside of the sprayer to prevent corrosion.
6. Extreme care should be taken in measuring spray products. Powders should be used in suitable sized packages or weighed accurately. Liquids should be poured into a suitable graduated container. Keep chemical containers low when pouring. Wear a filtered respirator and let the wind blow away from you to avoid dust and/or splashes contacting the skin or hair.
7. Store chemicals in a separate, plainly marked locked building. Keep the chemical in its original container with the label intact.
8. Dispose all empty containers after rinsing in accordance with local regulations & by-laws. Dispose of all unused chemicals and left over fertilizer in an approved manner
9. Keep a first aid kit and fire extinguisher available at all times when handling chemicals.

OPERATION
NOTE: Please read and complete operator's manual before turning on sprayer pump.
PRE-OPERATION CHECK LIST
• Tank and system should be flushed with water prior to use. This will also help remove any debris that may have gathered. Flushing the system will also reveal any possible leaks.
If leaks occur, tighten all appropriate fittings.
• Make sure all hoses are properly installed.
• Close all valves (to close, turn each of the coloured knobs clockwise).
• Open regulating valve (V900) by turning the large black knob counter clockwise until it becomes loose.
• Check to see if the wand trigger is in the OFF position.
• Make sure pump switch is in the off position.
• Connect pump wires to the tow vehicle (RED to + positive & BLACK to - negative).
• Add water until the tank is half full.
• Turn the switch to the on position and allow the pump to prime.
• Once the pump is primed, familiarize yourself with the valves, wand, nozzles, diaphragms, regulating valve, etc.
VALVE OPERATION
• The valve control gives complete control of the spray boom and trigger wand.
• To open a valve, turn it counter clockwise.
• To close a valve, turn it clockwise.
• Wand is controlled with the red knob.
Regulating Valve (Relief valve) (V900)
To increase pressure, turn large knob clockwise. To decrease pressure, turn counter clockwise.
Once desired pressure is reached, use locknut to hold in place.

5.0 NOZZLE SELECTION
5.1 Boom Nozzle Selection
Wilger ER80-02 Yellow tip & cap Combo-Jet nozzles are standard on the 100" (WPFA100),
140" (WPFA140), & 60" (WPFA60) boom. If you find by using the following directions and nozzle chart, that these nozzles are not the correct size for your spraying needs, other nozzles are available from your Westward Dealer.
TO USE THE FOLLOWING CHART:
1. You must know your desired forward speed (example 3 MPH).
2. You must know the pressure (PSI) you want to spray at (example 30 psi).
3. You must know your desired application rate (example 14 gallons per acre).
KNOWING THESE THREE FACTS, PROCEED AS FOLLOWS:
1. Locate the correct speed column on the chart below (example 3 M.P.H.).
2. Find the number in that column which is closest to your desired application rate and is also opposite the desired pressure (example 14.2 GPA is closest to 14 GPA and opposite 30 psi).
3. For this example, you would select the 02 YELLOW nozzle.
NOTE:
Using this chart will bring you very close to your desired application rate. However, for final pressure setting, you must calibrate your sprayer (Section 6.0).

6.0 CALIBRATION
WARNING:
ALWAYS CALIBRATE YOUR SPRAYER WITH CLEAN WATER ONLY!
WEAR PROTECTIVE CLOTHING SUCH AS RUBBER GLOVES,
GOGGLES AND COVERALLS
Why must you calibrate a sprayer?
A nozzle selection chart will tell you what application rate you should expect. Variations due to nozzle wear, errors in pressure adjustment, and tractor speedometer can result in a large error in application rate.
How do you calibrate a sprayer?
Calibration kits are available from WESTWARD, #818493 for U.S. Gallons and #818492 for metric calibration.
For accurate calibration, the sprayer is driven a specific distance at spraying speed and the length of time is recorded. The operator then measures the amount of water sprayed from one nozzle at spraying pressure for the same length of time noted. The amount of water sprayed provides a direct reading of application rate.
Slight adjustments are then made by varying the pressure.
Here are some tips to remember when using the calibration kit method:
1. Calibrate with clean water only.
2. Follow the instructions in the calibration kit carefully.
3. Before calibration, check the flow of each nozzle.
If it puts out more than 10% of its original volume, replace it.
4. When determining the length of time required to drive a recommended distance, drive in actual field or lawn conditions with a half full sprayer. Repeat the test several times, then take the average of the times recorded.
5. Calibration of the sprayer should be completed at the beginning of the season and repeated every 2 to
3 full days of spraying, and every time you change volume rate or use different nozzles.
6.1 Calibration (Ounce Method)
If you do not wish to use the calibration kit method, the following method may be used. All you need is a tape measure, stop watch and a container that accurately measures U.S. fluid ounces.
1. Fill the sprayer tank approximately half full with clean water.
2. Set up two stakes, 204 ft. apart in actual spraying conditions.
3. While driving at spraying speed, note the length of time required to drive 204 ft. Repeat several times and take the average of the times recorded.
4. With the sprayer operating at intended spraying pressure, collect the output from one nozzle for the length of time determined in step 3. The number of U.S. fluid ounces will exactly measure the application rate.
e.g. 15 U.S. fluid ounces = 15 U.S. gallons per acre
NOTE: This method only works if the nozzle spacing is 20".
For conversion to Imperial gallons per acre, multiply U.S. GPA x .833. For conversion to liters per hectare, multiply U.S. GPA x 9.34. For conversion to liters per acre, multiply U.S. GPA x 3.78.

7.0 MAINTENANCE
IMPORTANT:
Always clean the boom at the end of your workday or before servicing is done to avoid unnecessary contact with chemicals.
In order to derive full benefit from the sprayer for many years, the following few, but important rules should be followed.
7.1 Cleaning the Sprayer
Read the entire label of the chemical used. Take note of any particular instructions regarding recommended protective clothing, deactivating agents, etc. Read the detergent and deactivating agent labels. If cleaning procedures are given, follow them closely.
Be familiar with local legislation regarding disposal of agricultural chemicals, mandatory decontamination methods, etc. Contact the appropriate office, e.g. Department of Agriculture.
Cleaning starts with calibration as a well calibrated sprayer will ensure the minimal amount of remaining spray liquid. It is a good practice to clean the sprayer immediately after use thereby rendering the sprayer safe and ready for the next application. This also prolongs the life of the components.
It is sometimes necessary to leave the spray liquid in the tank for short periods of time (e.g. overnight), or until the weather becomes suitable for spraying again. Unauthorized persons and animals must not have access to the sprayer under these circumstances.
Cleaning
1. Dilute the remaining spray liquid in the tank with at least 10 parts water and spray the liquid out into the field or lawn you have just sprayed.
2. Select and use the appropriate protective clothing. Select detergent suitable for cleaning and suitable deactivation agents if necessary.
3. Rinse and clean sprayer and tractor externally. Use detergent if necessary.
4. Remove all filters and clean them. Be careful not to damage the mesh. Replace filters when the sprayer is completely clean.
5. With the pump running, rinse the inside of the tank. Remember the tank roof. Rinse and operate all components and any equipment that has been in contact with the chemical.
6. After spraying the liquid out again in the field or lawn, stop the pump and fill at least 1/5 of the tank with clean water. Note that some chemicals require the tank to be completely filled. Add appropriate detergent and/or deactivating agent, e.g. Washing soda or Triple ammonia.
NOTE: If a cleaning procedure is given on the chemical label, follow it closely.
7. Start the pump and operate all controls enabling the liquid to come in contact with all the components.
Leave the distribution valves until last. Some detergents and deactivating agents work best if left in the tank for a short period. Check the label.
8. Drain the tank and let the pump run dry. Rinse inside of tank, again letting the pump run dry.
9. Stop the pump. If the chemicals used have a tendency to block nozzles, remove and clean them now.
10. Replace all filters and nozzles and store the sprayer. If, from previous experiences, it is noted that the solvents in the chemicals are particularly aggressive, store the sprayer with the tank lid open.
NOTE: If the sprayer is cleaned with a high pressure cleaner, we recommend lubrication of the entire machine.
12
7.2 Pump Maintenance
To disassemble pump head assembly, remove two screws A (Fig. 5) at front of pump. Rotate bearing cover so access notch is aligned with cam/bearing set screw on motor shaft. Loosen set screw with 1/8" allen wrench and slide pump head off motor shaft.
To install replacement pump head, coat motor shaft with grease prior to assembly. Slide cam/bearing assembly over motor shaft. Align set screw with dimple in motor shaft and tighten securely. Set screw must center in shaft dimple for correct cam position, otherwise diaphragm may be damaged. Rotate pump head to original position. Install top and bottom screws A (Fig. 5) and tighten.
Operate pump to make sure flow and motor speed are normal. If operation is noisy, flow is down or pressure is low, recheck cam/ bearing set screw to make sure it is centered in the shaft dimple (See Section 12.0, page 18 for SHURFLO PUMP BREAKDOWN).
13
8.0 STORAGE
When the spraying season is over, you should devote some extra time to the sprayer. If chemical residues are left over in the sprayer for long periods, it can reduce the life of the individual components. To preserve the sprayer and protect the components, carry out the following off-season storage program:
1. Clean the sprayer completely - inside and outside - as described in Section 7.1 “Cleaning the Sprayer“.
Make sure that all valves, hoses and auxiliary equipment have been cleaned with detergent and flushed with clean water afterwards, so no chemical residues are left in the sprayer.
2. Replace any damaged seals and repair any leaks.
3. Empty the sprayer completely and let the pump work for a few minutes. Operate all valves and handles to drain as much water out of the spraying circuit as possible. Let the pump run until air is coming out of all nozzles.
4. Fill the tank with 3 - 5 gallons of an ethylene glycol base anti-freeze mixture at the ratio for the desired temperature protection. Run the pump and circulate the anti-freeze through the distribution valves and boom lines. Spray the handgun into the tank until anti-freeze sprays out to make sure the line is full of anti-freeze.
NOTE: Never use diesel fuel in a sprayer.
5. When the sprayer is dry, remove rust from any scratches in the paint and touch up the paint.
6. Lubricate the boom.
7. Remove the glycerine-filled pressure gauge and store in a vertical position in a frost-free environment.
8. Store the electric wires, switch and inline fuse in a dry plastic bag to protect them against moisture, dirt, and corrosion.
9. To protect against dust, the sprayer can be covered by a tarpaulin. Ensure ventilation to prevent condensation.
8.1 Preparation After Storage
