Storage; Preparation After Storage - Hardi ES 50 Operator's Manual

8.0 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
following off-season storage program:
1. Clean the sprayer completely - inside and outside - as described in
Section 7.1 "Cleaning 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 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 possible. Let the pump run until air is
coming out of all nozzles.
4. Fill the tank with 3 - 5 gallons of an ethylene glycol base anti-freeze
mixture at the ratio for the desired temperature protection. Run the
pump and circulate the anti-freeze through the distribution valves
and boom lines. Spray the handgun into the tank until anti-freeze
sprays out to make sure the line is full of anti-freeze.
NOTE: Never use diesel fuel in a sprayer.
5. When the sprayer is dry, remove rust from any scratches in the paint
and touch up the paint.
6. Lubricate the boom (Section 7.2).
7. Remove the glycerine-filled pressure gauge and store in a vertical
position in a frost-free environment.
8. To protect against dust, the sprayer can be covered by a tarpaulin.
Ensure ventilation to prevent condensation.

8.1 Preparation After Storage

After a storage period, the sprayer should be prepared for the next
season in the following way:
1. Remove the cover (If fitted).
2. Fit the pressure gauge again. Seal with Teflon tape.
3. Connect the sprayer to the tow vehicle (Section 3.0).
4. Empty the remaining antifreeze into an approved container.
5. Rinse the entire liquid circuit on the sprayer with clean water. Don't
forget to flush the boom and handgun lines also.
6. Fill with clean water and check all functions (Section 4.0).
