Dear Owner,
Thank you for purchasing a HARDI®product and welcome to the ever-
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 application equipment.
Please take the time to thoroughly read the Operator’s Manual before
using your equipment.You will find many helpful hints as well as
important safety and operation information.
Some of the features on your ATV 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.

5HARDI®ATV SPRAYER DIAPHRAGM OPERATOR'S MANUAL
1.0 INTRODUCTION
We congratulate you for choosing a HARDI®plant protection product.
The reliability and efficiency of this product depends on your care.
The first step is to carefully read and pay attention to this operator's
manual. It contains essential information for the efficient use and long
life of this quality product.
This manual covers the HARDI®ATV sprayer equipped with gas engine
directly coupled to a HARDI®1203 diaphragm pump. The HARDI®ATV
sprayer is available in a 150 gallon (550 L) capacity.
The heart of your sprayer is the diaphragm pump. The design is simple,
resulting in low maintenance requirements and guaranteed pump life.
The bearings and crankshaft are grease lubricated and are therefore
protected from spray solution if any diaphragm fails in service. A drain
hole is located in the base of the crank case to facilitate the draining of
any foreign matter. The pump is self-priming and can be run dry without
damage.
The HARDI®ATV sprayer is equipped with a manual control which
features: electrically operated master on/off control, electrically
operated boom distribution valves, manual pressure adjustment valve,
pump bypass agitation, and a 4" boom pressure gauge.
The tank, made of impact proof and chemical resistant polyethylene,
has a purposeful design with rounded contours which allows for
effi cient cleaning and draining. The tank is designed with a large deep
sump, so that it can be completely emptied even when the sprayer is
used on slopes. A tank level indicator is molded into the front and side
of the tank. A remote operated tank drain valve is fitted for safe and
easy draining. Bottom tank suction includes a shut-off valve for easy
cleaning of suction filter.
Available options include: 4 gallon (15 L) clean water dispenser, hose
wrap with 25' of 3/8" hose and a model 60L HARDI®spray gun, filter
basket and SMV sign.
The HARDI®ATV sprayer is available with either the 20', 26', 33' or 40'
MB boom. The 40' MB boom features a self-levelling trapeze center. All
booms feature ISO flat fan nozzles with 20" spacing.

6 HARDI®ATV SPRAYER DIAPHRAGM OPERATOR'S MANUAL
The frame and boom of your HARDI®ATV sprayer are finished with a
powder coat paint which provides maximum protection from chemicals
and rust.

be alert to the potential for personal injury.
Follow recommended precautions and safe
operating practices.
2.1 Follow Safety Instructions
1. Carefully read all the safety messages in this manual and the
safety labels fitted to the machine. Keep safety labels in good
condition. Replace missing or damaged safety labels. Make sure

when on public roads. Avoid personal injury or death resulting from
any accidents by using flashing lights. Some local regulations may
require installation of flashing warning lights.
6. Check local regulations before transporting the HARDI®ATV sprayer
on public roads. It may be necessary to use a trailer.
7. Before leaving the ATV/tractor seat, stop the engine, put all controls
in neutral, and put the transmission control lever in the park position
or neutral with the brakes locked. Read the ATV/tractor operator's
manual for added safety precautions.

damaged parts immediately. Replace worn or broken parts.

10 HARDI®ATV 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
specific details including, physical and health hazards, safety proce-
dures, 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 im-
mediately 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 fill, flush, calibrate and decontaminate sprayer
where chemicals will not drift or run off to contaminate people, ani-
mals, 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 filtered 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 first aid kit and fire extinguisher available at all times when
handling chemicals.
