After Storage
After a storage period, the sprayer should be prepared for the next season the following way:
1. Remove the tarpaulin.
2. Remove the jack stands from the wheel axle, and adjust the tyre pressure.
3. Wipe off the grease from the hydraulic ram piston rods.
4. Fit the pressure gauges again. Seal with Teflon tape or similar.
5. Connect the sprayer to the tractor, including pneumatic, 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.
6. Check the hydraulic hoses for damage and correct connection to the tractor (see flow directions marked on the hoses).
7. 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.
8. Drain the antifreeze mixture from the MainTank and spray boom.
9. 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 for correct connection to the tractor and that hydraulic or pneumatic brake hoses are intact and without
damage.
13. Check the working order of the brakes. Please note reduced brake power, until the rust worn off the drums. Always
brake lightly until the drums are clean.
14. 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.
15. Check traffic lights are visible and in good working order. Check the protection glasses are clean and without damage.
16. Check the speed sensor and other sensors are in good condition and free of dirt.
17. Check that the spray boom folds correctly. Make adjustments if needed and repair oil leaks if any.
18. Check that the boom hydraulic hoses and electric cables are in place, and follow the folding movements without
damage.
