5 - Operation116± WARNING! It is the responsibility of the sprayer operator or owner, that the sprayer is cleaned sufficiently to preventcontamination of the environment, crop damages and health and safety hazards to the operator and the public.HARDI cannot be held responsible for any damages or incidents related to insufficient cleaning. ATTENTION! The rinsing nozzles cannot always guarantee a 100% cleaning of the tank. Clean manually with a highpressure cleaner afterwards, especially if the next crop is sensitive to the chemical just sprayed!Using the Drain ValveThe drain valve is operated from the right side of the sprayer’s fronttheladder and is located just beside the main tank lid.1. Pull the string to open the drain valve.2. The valve is spring-loaded, but can be kept open by pulling thestring upwards in the V-shaped slit.3. To release, pull the string downward and the valve will closeautomatically.If draining residues, e.g. liquid fertilizer into a reservoir, a snap couplerwith hose can rapidly be connected to the drain valve, and the liquid issafely drained.Pressure DrainingIt is possible to drain to an external tank. This is done the following way:1. Connect a hose from an external tank to the quick coupler on thesprayer.2. Turn the pressure valve towards .3. Turn the suction valve towards .4. Engage the PTO to start the pump.5. When the tank is drained, then turn off the PTO again.6. Disconnect the hose and mount the cap for the quick coupler.€ DANGER! Ensure that the cap for the quick coupler is correctlymounted on the filling stud in its locked position. Failure to do socauses a risk of contamination and injury from the quick couplercap being “shot” off when pressurized! If it is not possible tomount the lid completely, lubricate the rubber seal and the griphooks and try again.
