In order to derive full benefit from the sprayer for many years the fol-
lowing few but important rules should be kept:

Cleaning the sprayer

Guidelines
Read the whole label of the chemical. Take note of any particular
instructions regarding recommended protective clothing, deactivating
agents, etc. Read the detergent and deactivating agent labels. If clean-
ing procedures are given, follow them closely.
Be familiar with local legislation regarding disposal of pesticides
washings, mandatory decontamination methods, etc. Contact the
appropriate body, eg. Dept of Agriculture.
Pesticide washings can usually be sprayed out on a soakaway. This is
an area of ground that is not used for cropping. You must avoid seep-
age or run-off of residues into streams, water courses, ditches, wells,
springs, etc. The washings from the cleaning area must not enter
sewers. Drainage must lead to a soakaway.
Cleaning starts with the calibration, as a well calibrated sprayer will
ensure the minimal amount of remaining spray liquid.
It is good practice to clean the sprayer immediately after use thereby
rendering the sprayer safe and ready for the next pesticide application.
This also prolongs the life of the components.
It is sometimes necessary to leave spray liquid in the tank for short
periods, eg. overnight, or until the weather becomes suitable for spray-
ing again. Unauthorized persons and animals must not have access to
the sprayer under these circumstances.
If the product applied is corrosive, it is recommended to coat all metal
parts of the sprayer before and after use with a suitable rust inhibitor.
Remember: Clean sprayers are safe sprayers.
Cleaning
1. Dilute remaining spray liquid in the tank with at least 10 parts water
and spray the liquid out in the field you have just sprayed.
