Storage
When the spraying season is over,
you should devote some extra time
to the sprayer before it is stored.
If chemical residues are left in the sprayer for long
periods, it can reduce the life of individual components.
Preparation before off season storage
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
Cleaning
(Page 24). Make sure that all
valves, hoses and auxiliary equipment have been
cleaned with detergent and flushed with clean water,
so no chemical residues are 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 is coming out of
all nozzles. Remember to drain the rinsing tank.
Ensure the foam marker is rinsed and drained.
4 If the sprayer is not stored in a frost free place, pour
in a mixture of Ethylene Glycol based anti-freeze and
water at the ratio for the desired temperature protec-
tion. Volume of mixture should be about 1% of tank
volume. Run the sprayer and circulate the anti-freeze
in the pump, controls and boom lines.
5 Lubricate all lubricating points regardless of intervals
stated.
6 When the sprayer is dry remove rust from possible
scratches or damages in the powdercoat and touch
up with paint.
7 Remove the Glycerine filled gauges and store them
in a frost free vertical position.
8 Apply a thin layer of anti-corrosion oil to all metal
parts, hoses and tyres. Suggested products for
protecting your equipment are HENKEL, SHELL
ENSIS or one of the CASTROL RUSTILLO range,
eg DW9011M1. Contact your Hardi Dealer for
updated recommendations.
There are many factors that affect the selection of
protective oils, such as temperature and humidity,
and exposure to UV, salt and chemicals. Your local
distributor of oil products will be able to advise on the
best specific formula for your local conditions.
9 Fold the boom to transport position and relieve
pressure from all hydraulic functions.
10 All electric plugs and sockets are to be stored in a
dry plastic bag to protect them against damp, dirt and
corrosion.
11 Remove any control boxes and display (if fitted) from
the tractor and store them inside where it is dry and
clean.
12 Wipe the hydraulic snap-couplers clean and fit the
dust caps.
13 Apply grease onto all hydraulic ram piston rods that
are not fully retracted in the barrel, to protect against
corrosion.
14 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.
15 To protect against dust the sprayer can be covered
by a tarpaulin. Ensure ventilation to prevent conden-
sation.
