Off-Season Storage
Off-Season Storage Program
To preserve the sprayer intact and to protect its components, the following off-season storage program is carried out.
Before storage
When the spraying season is over, you should devote some extra time to the sprayer.
If chemical residues are left over in the sprayer for longer periods, it may reduce the life of its individual components.
1. Clean the sprayer completely - inside and outside - as described under “Cleaning” on page 60. Make sure that all valves,
hoses and auxiliary equipment have been cleaned with detergent and flushed with clean water afterwards, so that no
chemical residues are left in the sprayer.
2. Replace any damaged seals and repair any leaks.
3. Empty the sprayer completely, and let the pump work for a few minutes. Operate all valves and handles to drain as
much water off the spraying circuit as possible. Let the pump run until air comes out of all nozzles. The rinsing tank is
also drained.
4. Pour approximately 50 litres of antifreeze mixture, consisting of 1/3 anti-freeze and 2/3 water, into the tank.
5. Engage the pump and operate all valves and functions, operating unit, chemical inductor etc., allowing the antifreeze
mixture to be distributed around the entire circuit. Open the operating unit main valve ON/OFF and distribution valves,
so that the antifreeze is sprayed through the nozzles as well. The antifreeze will also prevent O-rings, seals, diaphragms
etc. from drying out. On sprayers with a FlexCapacity pump, this must also be engaged and flushed.
6. Lubricate all lubricating points according to the lubricating intervals.
7. When the sprayer is dry, remove rust from scratches or damage in the paint, if any, and touch up the paint.
8. Remove the glycerine-filled pressure gauges and store them frost-free in vertical position.
9. 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.
10. Fold the boom in transport position and relieve pressure from all hydraulic functions.
11. All electric plugs and sockets are to be stored in a dry plastic bag to protect them against moisture, dirt and corrosion.
12. Remove the control boxes and computer display from the tractor. Store them dry and clean (indoor) in a non-
condensing environment.
13. Wipe hydraulic snap couplers clean and fit the dust caps.
14. Apply grease to all hydraulic ram piston rods, which are not fully retracted in the housing, to protect against corrosion.
15. To protect against dust, the sprayer can be covered by a tarpaulin. 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 hydraulic ram piston rods.
3. Fit the pressure gauges again. Seal with Teflon tape.
4. Connect the sprayer to the tractor, including hydraulics and electrics.
5. Check all hydraulic and electric functions.
6. Empty the tank for remaining antifreeze.
7. Rinse the entire liquid circuit of the sprayer with clean water.
8. Fill with clean water and check all functions.
