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 can reduce the life of the individual compo-
nents.

To preserve the sprayer intact and to protect the compo-
nents, carry out following off-season storage program.
1. Clean the sprayer completely - inside and outside - as
described under Cleaning of the sprayer. Make sure
that all valves, hoses and auxiliary equipment have
been cleaned with detergent and flushed with clean
water afterwards, so no chemical residue is left in the
sprayer.
2. Renew possible damaged seals and repair possible
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 possi-
ble. Let the pump run until air is coming out of all
nozzles. Remember to drain the rinsing tank also.
4. Pour appr. 50 litre (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 func-
tions on the MANIFOLD, operating unit, FILLER 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 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 lubri-
cating scheme - regardless of intervals stated.
7. When the sprayer is dry, remove rust from possible
scratches or damages in the paint 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 RUSTILLO 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 the HARDI PILOT
control box + display from the tractor, and store them
dry and clean (in-house).
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. Chock up the wheels, to prevent moisture damage
and deformation of the tyres. Tyre blacking can be
applied to the tyre walls to preserve the rubber.
16. Drain air brake tank for condensed water.
17. To protect against dust the sprayer can be covered
by a tarpaulin. Ensure ventilation to prevent conden-
sation.

After a storage period the sprayer should be prepared
for the next season the following way:
1. Remove the cover
2. Remove the support from the wheel axle and adjust
the tyre pressure.
3. Wipe off the grease from hydraulic ram piston rods.
4. Fit the pressure gauges again. Seal with Teflon tape.
5. Connect the sprayer to the tractor including hydraulics
and electrics.
6. Check all hydraulic and electric functions.
7. Empty the tank for remaining anti-freeze.
8. Rinse the entire liquid circuit on the sprayer with clean
water.
9. Fill with clean water and check all functions.
10. Check function of brakes. Please note that brake
power will be reduced until the rust are worn off the
drums. Always brake lightly until the drums are
clean.
