Decontamination
Decontamination of your spraying equipment is
important when changing chemicals or application
methods.
Information specific to your circumstances, the
spraying equipment being used and the chemicals
being applied should be provided by your
agronomist or chemical supplier.
Always wear the recommended personal protective
equipment and use caution while working with
chemicals.
BASIC DECONTAMINATION WITH OPTIONAL
INDUCTION HOPPER
1. Fill the main spray tank with approximately 1000 L
of fresh water.
2. Lower the induction hopper and put the
appropriate amount of decontaminating agent
into it.
3. Turn on the agitation jet on the hopper and
allow it to fill the hopper to the top. Once
full, turn the jet off and leave the hopper to
sit for a few minutes. This is to ensure that the
decontaminating agent fully neutralises any of the
chemicals that were in the hopper.
4. Use the venturi to induct the contents of the
hopper into the main spray tank.
5. Recirculate the decontaminating agent through
the system while the main tank rinse nozzles are
running (pressure supplied from the main spray
pump e.g. pressure delivery manifold).
Sprayer Transportation
1. Make sure the tractor has sufficient towing and
braking capacity to tow the sprayer.
2. All relevant transport regulations must be
adhered to when transporting the sprayer. (ie:
speed regulations, oversize signs, flashing light, etc.)
It is the operator's responsibility to know the
relevant regulations.
3. Make sure the sprayer is securely hitched to the
tractor.
4. Ensure that the boom is securely supported when
travelling and that the isolation ball valves on the
hydraulic lift cylinders are closed.
5. Where a road pack has been installed connect tail
light plug.
36 - Chapter 8 - Operation
6. Turn off all taps to allow the pressure relief valve
to blow off and purge the 'relief to tank' line.
7. Operate induction equipment (if fitted), with a
quantity of fresh water in order to flush venturi
system.
8. Once complete, drain chemical induction hopper
delivery hose externally.
NOTE: Lower the hopper and open the lid to allow
it to drain completely.
9. Turn on boom recirculation to flush all boom lines
back to main tank.
10. Once the main tank has emptied, flush the
system again using fresh water to ensure the
decontaminating agent is removed from the
system.
11. Once the main tank is empty, the hose between
the tank and the suction filter also needs to be
drained. Close the valve on the Suction Filter.
12. Remove the suction filter bowl and clean as per
'Suction Filter Cleaning' instructions earlier in this
chapter.
13. Return switch to main chemical tank. Stand
clear of the filter when turning the valve to main
chemical tank as chemical will be coming out.
Catch all of the chemical in a suitable container so
it can be disposed of in the correct manner.
CAUTION: Take care when reversing with the
sprayer attached. If driver visibility is restricted, use
another adult with a clear view to the rear of the
sprayer to give reversing directions.
CAUTION: It is the operator's responsibility to
know the tare weight and gross weight of the
sprayer. If any alterations are made to the sprayer,
it is the operator's responsibility to know the tare
weight and the gross weight of the modified sprayer
at all times.
