8. Apply a thin layer of anti-corrosion oil (e.g. SHELL ENSIS FLUID, CASTROL RUSTILO or similar) on all metal parts. Avoid
oil on rubber parts, hoses and tyres.
9. Fold the boom into transport position and relieve the pressure from all hydraulic functions.
10. All unplugged electric plugs and sockets are to be stored in a dry plastic bag to protect them against moisture, dirt
and 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, not fully retracted in the housing, to protect against corrosion.
14. Cover the sprayer with a tarpaulin to protect against dust. Ensure ventilation to prevent condensation.

After Storage

After 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 the 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 and
cables are free to move along when driving with the sprayer. No rubbing or stretching of cables and hoses.
5. Check the hydraulic hoses for damage and correct connection to the tractor (see flow directions marked on the hoses).
6. Check for correct connection between the PTO shaft and the tractor, and protection guards are in good working order.
See the PTO instruction manual delivered for more about correct installation.
7. Drain the antifreeze mixture from the MainTank and spray boom.
8. Fill with clean water and check all functions. Do a liquid test:
A. Fill a small amount of water into the MainTank and circulate it around the liquid system.
B. Manually set spray pressure to 5 bar.
C. Check for leaks and repair if any.
D. Check spray patterns and water jets from the nozzles.
10. Rinse the entire sprayer liquid system with clean water.
11. Check that the MainTank is clean inside and check the function of the drain valve.
12. Check that the electric cables to the tractor are intact and correctly connected. Also, check that:
• Cable sheaths are without damage due to wear, stretching or rubbing.
• Electric plugs are without copper rust and damage.
• Electric boxes are without cracks.
13. Check traffic lights are visible and in good working order. Check the protection glasses are clean and without damage.
14. Check the sensors are in good condition and free of dirt.
15. Check that the spray boom folds correctly. Make adjustments if needed and repair oil leaks if any.
16. Check that the boom hydraulic hoses and electric cables are in place, and follow the folding movements without being
damaged.
