HARDI
Dear Owner,
Thank you for purchasing a HARDI
increasing family of HARDI® sprayer owners.
Our sprayers and accessories are rapidly becoming a familiar sight
on North American farms. We believe that this results from growers
becoming increasingly conscious of crop protection input costs and the
vital need for cost effective spray application equipment.
Please take the time to thoroughly read the Operator’s Manual before
using your equipment. You will fi nd many helpful hints as well as
important safety and operation information.
Some of the features on your HARDI® sprayer were suggested by
growers. There is no substitute for “on farm” experience and we invite
your comments and suggestions. If any portion of this instruction book
remains unclear after reading it, contact your HARDI® dealer or service
personnel for further explanation before using the equipment.
For Product, Service or Warranty Information:
- Please contact your local HARDI® dealer.

fi rst step is to carefully read and pay attention to this operator's manual.
It contains essential information for the effi cient use and long life of this
quality product.
As this instruction book covers all N-series models, please pay
attention to the sections dealing with your specifi c model.
This manual covers the HARDI
®
N-series 3-PT sprayers, available in
105, 155 or 210 gallon (400 L, 600 L or 800 L) capacities. They are
equipped with a HARDI® 603, 1203 or 1303 diaphragm pump (540
RPM P.T.O. drive), 3-PT frame and tank with electrical (EC) or manual
(ET or BK) controls. Available standard booms include:

10 HARDI® N-SERIES 3-PT SPRAYER DIAPHRAGM OPERATOR'S MANUAL
2.3 Handling Chemical Products Safely
1. Direct exposure to hazardous chemicals can cause serious injury.
These chemicals can include lubricants, coolants, paints, adhesives
and agricultural chemicals. Material Safety Data Sheets (M.S.D.S.)
are available for all hazardous chemicals which inform the user of
specifi c details including, physical and health hazards, safety procedures, and emergency response techniques.
2. Protective clothing such as rubber gloves, goggles, coveralls and
respirator must be worn while handling chemicals. All protective
clothing should be kept in excellent condition and cleaned regularly
or discarded.
3. If chemicals come in contact with any exposed skin areas, wash immediately with clean water and detergent. Never place nozzle tips or
any other components that have been exposed to chemicals to lips
to blow out obstructions. Use a soft brush to clean spray nozzles.
4. Dedicate an area to fi ll, fl ush, calibrate and decontaminate sprayer
where chemicals will not drift or run off to contaminate people, animals, vegetation, water supply, etc. Locate this area where there is
no chance of children coming in contact with this residue.
5. Decontaminate equipment used in mixing, transferring and applying
chemicals after use. Follow the instructions on the chemical label for
the correct procedure required. Wash spray residue from outside of
the sprayer to prevent corrosion.
6. Extreme care should be taken in measuring spray products. Powders
should be used in suitable sized packages or weighed accurately.
Liquids should be poured into a suitable graduated container. Keep
chemical containers low when pouring. Wear a fi ltered respirator
and let the wind blow away from you to avoid dust and/or splashes
contacting the skin or hair.
7. Store chemicals in a separate, plainly marked locked building. Keep
the chemical in its original container with the label intact.
8. Dispose all empty containers after rinsing in accordance with local
regulations & by-laws. Dispose of all unused chemicals and left over
fertilizer in an approved manner
9. Keep a fi rst aid kit and fi re extinguisher available at all times when
handling chemicals.
