Off-season storage
Off-season storage program
To preserve the sprayer intact and to protect the components, carry out following off-season storage program.
Before storage
When the spraying season is over, you should devote some extra time to the sprayer. If chemical residue is left over in the
sprayer for longer periods, it may reduce the life of the individual components.
1.
Clean the sprayer completely - inside and outside - as described under “Cleaning” on page 52. Make sure that all valves,
hoses and auxiliary equipment have been cleaned with detergent and flushed with clean water afterwards, so that no
chemical residue is left in the sprayer.
2.
Renew 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. Don’t forget to drain
the rinsing tank also.
4.
Pour approx. 50 litres (11 Imp.gal) anti-freeze mixture consisting of 1/3 automotive 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 anti-freeze
mixture to be distributed around the entire circuit. Open the operating unit main ON/OFF valve and distribution valves
so that the anti-freeze is sprayed through the nozzles as well. The anti-freeze will also prevent O-rings, seals,
diaphragms etc. from drying out.
6.
Lubricate all lubricating points according to the lubricating scheme - regardless of intervals stated.
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 damp, dirt and corrosion.
12.
Remove the control boxes and computer display from the tractor, and store them dry and clean (indoor). A non-
condensing environment is recommended.
13.
Wipe hydraulic snap-couplers clean and fit the dust caps.
14.
Apply grease on all hydraulic ram piston rods which are not fully retracted in the barrel to protect against corrosion.
15.
To protect against dust the sprayer can be covered by a tarpaulin. Ensure ventilation to prevent condensation.
