Off-Season Storage; Preparation After Off Season Storage - Hardi New NAVIGATOR 1100 Operator's Manual

Off-season 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 long periods, it can reduce
the life of the individual components. To preserve the
sprayer and protect the components, carry out the fol-
lowing 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 fl ushed with
clean water afterwards, so 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 out of the spraying circuit as
pos si ble. Let the pump run until air is coming out of
all nozzles. Remember to drain the fl ush tank also.
4. Pour appr. 13 gal. (50 liters) anti-freeze mixture con-
sist ing 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 system, ECP unit, CHEM
FILLER, etc. allowing the anti-freeze mixture to be
distributed around the entire circuit. Activate the ECP
main on/off switch and distribution valves so the anti-
freeze is sprayed through the nozzles as well.
The anti-freeze will also prevent O-rings, seals, dia-
phragms, etc. from drying out.
6. When the sprayer is dry, remove rust from any
scratches or damages in the paint and touch up the
paint.
7. Lubricate all lubricating points according to the lubri-
cating scheme - regardless of intervals stated.
8. Remove the glycerine-fi lled pressure gauges and
store them in a vertical position in frost free con di -
tions.
9. Apply a thin layer of anti-corrosive oil (e.g. SHELL
ENSIS FLUID, CASTROL RUSTILLO or similar) on
all metal parts. Avoid oil on rubber parts, hoses and
tires.
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 all the control boxes (including any rate
controller/monitor control box and display) from the
tractor and store them in a dry and clean location.
13. Wipe hydraulic snap-couplers clean and fi t 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. Jack up the axle and place wooden blocks under
the wheels to prevent moisture damage and de for -
ma tion of the tires. Tire black can be applied to the
tire side walls to preserve the rubber.
16. To protect against dust, the sprayer can be cov ered
by a tarpaulin. Ensure ventilation to prevent con-
den sa tion.
Preparation after off-season storage
After a storage period, the sprayer should be prepared
for the next season the following way:
1. Remove the cover. (If fi tted)
2. Remove the blocks from under the wheels and adjust
the tire pressure.
3. Wipe off the grease from hydraulic ram piston rods.
4. Fit the pressure gauges again. Seal with Tefl on tape.
5. Connect the sprayer to the tractor, including hy drau -
lics 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.
