Apply a thin layer of anti-corrosion oil (e.g. SHELL ENSIS FLUID, CASTROL RUSTILO or similar) on all metal parts. Avoidoil on rubber parts, hoses and tyres.9. Fold the boom into transport position and relieve pressure from all hydraulic functions.10. All dismounted electric plugs and sockets are to be stored in a dry plastic bag to protect them against moisture, dirtand corrosion.11. Remove the control boxes and computer display from the tractor. Store them dry and clean (indoor) in a non-condensing environment.12. Wipe hydraulic snap couplers clean and fit the dust caps.13. Apply grease to all hydraulic ram piston rods, which are not fully retracted in the housing, to protect against corrosion.14. To protect against dust, the sprayer can be covered by a tarpaulin. Ensure ventilation to prevent condensation.After StorageAfter a storage period, the sprayer should be prepared for the next season the following way:1. Remove the tarpaulin.2. Wipe off the grease from hydraulic ram piston rods.3. Fit the pressure gauges again. Seal with Teflon tape or similar.4. Connect the sprayer to the tractor, including hydraulic, electric and electronic connections. Check that the hoses andcables are free to move along when driving with the sprayer. No rubbing or stretching of cables and hoses.5. Hydraulic hoses are connected correctly to tractor (see flow directions marked on the hoses), and they are withoutdamages.6. Electric cables to the tractor are intact and connected correctly. Cable sheaths are without damage due to wear,stretching and rubbing. The electric plugs are without copper rust and damages. Electric boxes are without cracks.7. PTO shaft is connected correctly to the tractor, and protection guards are in good working order. See the deliveredinstruction manual for the PTO for more about correct installation.8. Antifreeze mixture is drained from the tank and spray boom.9. Fill with clean water and check all functions. Liquid test: Fill a small amount of water in the tank and circulate it aroundthe liquid system. Spray pressure = 5 bar. Repair leaks if any. Check spray patterns and water jets from the nozzles.10. Rinse the entire liquid circuit of the sprayer with clean water.11. Check that the main tank is clean inside and close the drain valve.12. Traffic lights are visible and in good working order. The protection glasses are clean and without damages.13. Check all electric functions.14. PTO shaft is connected correctly to the tractor, and protection guards are in good working order. See the deliveredinstruction manual for the PTO for more about correct installation.15. Check that the spray boom folds correctly - make adjustments if needed. Repair oil leaks if any. Check that hydraulichoses and electric cables are in place, and that they and follow the folding movements without being damaged.16. Sensors are in good condition and free of dirt.
