Filling the clean water tank
A clean water tank for hand washing is fitted to the front of the
sprayer just above the product pump.
To fill the clean water tank:
1. Remove the lid and fill with clean water.
2. Replace the lid.
The clean water is accessible by operating the ball valve tap
located below the tank on the left hand side of the machine.
Clean water tank capacity:....................................15 litres
±
WARNING: The clean water tank is for washing hands and cleaning blocked nozzles only. Never drink from
this, or any other tank. Chemical contamination poses a serious health risk. If poisoning occurs note the
chemical(s) involved and seek medical advice immediately.
Cleaning
Introduction
The best performance and service life can be expected when the sprayer is properly cleaned and maintained. Clean
sprayers are safe and ready for action. Clean sprayers are less likely to be damaged by pesticides and their solvents.
€
DANGER: Agricultural chemicals can be dangerous. Read chemical labels and carefully follow safety
recommendations to the letter. Always use appropriate safety clothing and equipment (see section 2 of
this manual for further information).
÷
Note: Read instructions for cleaning carefully before starting on the job. This includes the instructions on
the chemical label which must be observed. Further information such as local restrictions on the disposal
of chemical washings and licensing for operators specific to your area can be obtained from the
Department of Primary Industries and the Environmental Protection Agency.
Cleaning Guidelines
• Read the whole chemical label. Take note of any particular instructions regarding recommended protective
clothing, deactivating agents, etc. Read the detergent and deactivating agent labels. If cleaning procedures
are given, follow them closely.
• Be familiar with local legislation regarding the disposal of chemical washings, mandatory decontamination
methods, etc. Contact the appropriate department, e.g. Department of Primary Industries / Environmental
Protection Agency.
• Legislation demands that you prevent seepage or run off of residue into streams, water courses, ditches,
wells, springs, etc. The washings from the cleaning area must not enter sewers. Drainage must be confined to
an approved catchment.
• Cleaning starts with accurate calibration. A well calibrated sprayer will ensure the minimum amount of spray
solution remains in the tank once the spray job is completed.
• It is good practice to clean and decontaminate the sprayer immediately after use, rendering the sprayer safe
and ready for the next spray job. This also prolongs the life of the components. Be aware that if chemicals are
left to dry out on the sprayers surfaces, they become much more difficult to remove.
• It is sometimes necessary to leave spray liquid in the tank for short periods, e.g. overnight, or until the weather
improves. Animals and unauthorised persons must not have access to the sprayer under these circumstances.
• If the product to be used is corrosive (ie: liquid fertiliser) apply a coat of a suitable rust inhibitor before and
after the job.
