Read the whole chemical label. Take note of anyparticular instructions regarding recommendedprotective clothing, deactivating agents, etc. Read thedetergent and deactivating agent labels. If cleaningprocedures are given, follow them closely.2. Be familiar with local legislation regarding disposal ofpesticides washings, mandatory decontaminationmethods, etc. Contact the appropriate department,e.g. Dept. of Agriculture.3. Pesticide washings can usually be sprayed out on asoakaway. This is an area of ground that is not usedfor cropping. You must avoid seepage or runoff ofresidue into streams, water courses, ditches, wells,springs, etc. The washings from the cleaning areamust not enter sewers. Drainage must lead to anapproved soakaway.4. Cleaning starts with the calibration, as a well cali-brated sprayer will ensure the minimal amount ofremaining spray liquid.5. It is good practice to clean the sprayer immediatelyafter use and thereby rendering the sprayer safe andready for the next pesticide application. This alsoprolongs the life of the components.6. It is sometimes necessary to leave spray liquid in thetank for short periods, e.g. overnight, or until theweather becomes suitable for spraying again. Unau-thorised persons and animals must not have accessto the sprayer under these circumstances.7. If the product applied is corrosive, it is recommendedto coat all metal parts of the sprayer before and afteruse with a suitable rust inhibitor.Remember:Clean sprayers are safe sprayers.Clean sprayers are ready for action.Clean sprayers cannot be damaged by pesti-cides and their solvents.Cleaning the tank1. Dilute remaining spray liquid in the tank with at least10 parts of water and spray the liquid out in the fieldyou have just sprayed - See paragraph ìUse of rinsingtank and rinsing nozzlesî.NOTE: It is advisable to increase the forward speed(double if possible) and reduce the pressure to 1.5bar (20 psi).2. Select and use the appropriate protective clothing.Select detergent suitable for cleaning and suitabledeactivating agents if necessary.3. Rinse and clean sprayer and tractor externally. Usedetergent if necessary.4. Remove tank and suction filters and clean. Be carefulnot to damage the mesh. Replace suction filter top.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 allcomponents and any equipment that has been incontact with the chemical.Before opening the distribution valves and sprayingthe liquid out, decide whether this should be done inthe field again or on the soakaway.6. After spraying the liquid out, stop the pump and fill atleast 1 / 5 of the tank with clean water. Note that somechemicals 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 chemi-cal label, follow it closely.7. Start the pump and operate all controls enabling theliquid to come in contact with all the components.Leave the distribution valves until last. Some deter-gents and deactivating agents work best if left in thetank for a short period. Check the label. The Self-Cleaning Filter can be flushed by removing the by-pass hose from the bottom of the filter. Stop the pumpand remove the hose. Start the pump for a fewseconds to flush filter. Be careful not to lose therestrictor nozzle.8. Drain the tank and let the pump run dry. Rinse insideof the tank, again letting the pump run dry.9. Stop the pump. If the pesticides used have a tendencyto block nozzles and filters, remove and clean themnow. Also check for sediment on the pressure side ofthe safety valve for the Self-Cleaning Filter.
