Avoid emptyingthe washings at the same spot every time and keep sufficient distance to the water environment. You must preventseepage or runoff of residue into streams, watercourses, ditches, wells, springs, etc. The washings from the cleaningarea must not enter sewers. Alternatively the washings can be retained in an appropriate receptacle, diluted anddistributed over a larger cultivated area - see also “Filling/Washing Location Requirements” on page 59.• Cleaning starts with the calibration, as a well calibrated sprayer will ensure the minimal amount of remaining sprayliquid.• It is good practice to clean the sprayer immediately after use, and thereby rendering the sprayer safe and ready for thenext pesticide application. This also prolongs the life of the components. It is strongly advised to perform an internalcleaning of the sprayer, when high concentrations of acids or chloride are present in the active ingredients, or if thespray liquid is corrosive. For the best result, use a cleaning agent recommended by HARDI, e.g. AllClearExtra.• It is sometimes necessary to leave spray liquid in the tank for short periods, e.g. overnight, or until the weather becomessuitable for spraying again. Unauthorized persons, children and animals must not have access to the sprayer underthese circumstances.• If the product applied is corrosive, it is recommended to coat all metal parts of the sprayer before and after use with asuitable rust inhibitor.• The sprayer must always be parked under roof to avoid rain washing off pesticides as well as build-up of spotcontamination in the soil. If parked outside, the sprayer should be parked on the filling/washing location in order toretain possible pesticides.
