The manufacturers sprayer manual should contain the following information:
identification of all replacement parts including an exploded diagram;
setting and calibration;
minimising the need to dispose of dilute pesticide;
cleaning and safe disposal of washings;
routine maintenance and storage;
accurate field use.
safe handling of pesticides and filling the tank;
disposal of leftover spray liquid and empty pesticide containers;
restrictor flow rate, atomizer speed and droplet sizes;
maximum restrictor size to be used in the sprayer;
precautions to minimize the risk of operator and environmental contamination;
recommended batteries (for battery-powered sprayers) and their installation;
a system for determining when batteries should be replaced.
It should also provide specific assurances that:
there is a practical system in place to assist in the provision of replacement parts for a minimum of five years after the date of manufacture;
all sprayer components that come into constant direct contact with ULV pesticide are resistant to undue deterioration from contact with ULV pesticide formulations;
straps and padding will resist undue deterioration from contact with ULV pesticide formulations;
the atomizers should be capable of 50 hours of operation at maximum operating speed without loss of performance or needing maintenance;
the sprayer must be capable of producing a droplet spectrum with VMD between 60 and 80 um, as determined by laser droplet analysis;
at least 50% of the spray volume must be in the size range 50 - 100 um, as determined by laser droplet analysis.
