Cleaning
General Info
Follow the following cleaning and maintenance program, in order to derive full benefit from the sprayer for many years.
μ
ATTENTION! Always read the individual paragraphs. Carefully read the instructions for cleaning/maintenance jobs
before starting on the job. If any portion remains unclear, or if it requires facilities not available, then please leave the
job to your HARDI dealer's workshop for safety reasons.

ATTENTION! A clean sprayer:
• Is a safe sprayer.
• Is ready for action.
• Does not take any damage from crop protection residues.
Guidelines
• Read the complete chemical label. 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 pesticides washings, mandatory decontamination methods, etc.
If in doubt, contact the appropriate authority.
• Usually the pesticide washings sprayed out on the field just sprayed or at a suitable cultivated area. Avoid emptying
the washings at the same spot every time and keep sufficient distance to the water environment. You must prevent
seepage or runoff of residue into streams, watercourses, ditches, wells, springs, etc. The washings from the cleaning
area must not enter sewers. Alternatively, retain the washings in an appropriate receptacle, diluted and distributed over
a larger cultivated area - also see "Filling/Washing Location Requirements" on page 113.
• Cleaning starts with the calibration, as a well-calibrated sprayer will ensure the minimal amount of remaining spray
liquid.
• Good practice is to clean the sprayer immediately after use, and thereby rendering the sprayer safe and ready for the
next pesticide application. This also prolongs the life of the components. Strongly advised is to perform an internal
cleaning of the sprayer, when high concentrations of acids or chloride are present in the active ingredients, or if the
spray liquid is corrosive. For the best result, use a cleaning agent recommended by HARDI, e.g. AllClearExtra.
• Sometimes it is necessary to leave spray liquid in the tank for short periods, e.g. overnight, or until the weather
becomes suitable for spraying again. Unauthorized persons, children and animals must not have access to the sprayer
under these circumstances.
• Recommended is to coat all metal parts of the sprayer before and after use with a suitable rust inhibitor, if the product
applied is corrosive.
• Always park the sprayer under roof to avoid rain-washing off pesticides as well as build-up of spot contamination in
the soil. If parked outside, park the sprayer on the filling/washing location in order to retain possible pesticides.
