Dear Owner,
Thank you for purchasing a HARDI® product and welcome to the everincreasing 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 fi nd 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.

1.0 INTRODUCTION
We congratulate you for choosing a HARDI® plant protection product.
The reliability and effi ciency of this product depends on your care.
The 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.
®
This manual covers the HARDI
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 poly eth yl ene,
has a purposeful design with rounded contours which allows for
ef fi 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 fi tted for safe and
easy draining. Bottom tank suction includes a shut-off valve for easy
cleaning of suction fi lter.
ATV sprayer equipped with gas engine
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, fi lter
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 fl at fan nozzles with 20" spacing.

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

4.10 Boom Height Adjustment
Correct boom height is important to ensure even spray distribution. For
the best distribution with HARDI® ISO F-110 standard fl at fan nozzles,
HARDI® recommends a boom height of 20" above the target surface.
Consult your HARDI® NOZZLES product guide for recommended
boom height for other nozzles.
The boom height for the MB booms on the ATV sprayer is adjusted
manually as follows:
1. Support boom with appropriate lifting device.
2. Loosen bolts A and remove bolts B (Fig. 13) on both sides of sprayer
frame.
3. Raise or lower boom to desired hole setting.
4. Reinstall bolts B and tighten bolts A (Fig. 13).

5.0 NOZZLE SELECTION
Correct selection of nozzle and calibration of the sprayer are critical to
achieve accurate and cost effective use of farm crop protection prod ucts.
Your HARDI
®
sprayer has been supplied with 110° fl at spray Red ISO
Color Tips™ that will apply approximately 20 U.S. GPA at 30 PSI and
5 MPH.
The 110° fl at spray nozzle was chosen rather than the 80 degree
nozzle for two reasons: 1- It may be used at a lower minimum height
which reduces the risk of wind drift; 2- it's greater overlap permits better uniformity of spray distribution, particularly if boom height varies on
rough ground. Normal boom height setting with 110° nozzles is 18" to
20" above the crop or weeds, whichever is taller.
Should you wish a different application rate or different type of nozzle,
HARDI® manufactures a nozzle for virtually every need.
IMPORTANT: Always consult your chemical supplier for rec om mend ed chemical rate and water application rate. Always wear
protective gloves when handling nozzles.
The following tables show what types of spray nozzles are suitable for
different applications. It is important to use the correct nozzle.

5.1 Calibration
WARNING: ALWAYS CALIBRATE YOUR SPRAYER WITH CLEAN
WATER ONLY! IN ADDITION, WEAR PROTECTIVE
CLOTHING WHEN CALIBRATING YOUR SPRAYER!
Why must you calibrate a sprayer?
A nozzle selection chart will tell you what application rate you should
expect. Variations due to nozzle wear, errors in pressure adjustment, and
tractor speedometer can result in a possible error in application rate.
How do you calibrate a sprayer?
Calibration kits are available from HARDI
®
, #818493 for US gallons &
#818492 for metric calibration.
Following are some tips to remember when using the calibration kit
method:
• When determining the length of time required to drive the recommended
distance, drive in actual fi eld conditions with a half-full tank.
• Repeat the test several times, each time avoiding the tracks from the
previous test. Take the average of the times recorded.
• Calibration of the sprayer should be completed at the beginning of the
season and repeated after every 2 to 3 full days of spraying, and every
time you change volume rate or use new nozzles.
• Before you calibrate, check the fl ow of each nozzle. If it puts out more
than 10% of its original volume, replace it.
Select your calibration method: Ounce method or Formula method.
Then follow the steps described in the corresponding section(s):
28 HARDI® ATV SPRAYER DIAPHRAGM OPERATOR'S MANUAL
Ounce Method
1. Determine how long it takes to cover the test strip. Use the following
chart to determine the length of your test strip. Row width for broadcast
application is equal to your nozzle spacing. For your drop nozzle or
band application, use row spacing.
Row width or nozzle spacing (in.) Distance (ft.)

24 170
22 185
20 204
18 227
16 255
14 291
2. Measure the amount of time it takes you to travel the test strip when
throttle is set at spraying speed.
3. In a container (with oz. measurements), catch the spray from one nozzle
for that amount of time. For drop or band nozzles, catch the spray from
all nozzles for the row.
4. Read the ounces in the container. That is the actual U.S. GPA applied.
(ounces = GPA)
29HARDI® ATV SPRAYER DIAPHRAGM OPERATOR'S MANUAL
Formula Method
1. Check your spraying speed. Measure a test strip of at least 200 feet
(300 feet is ideal). Travel the distance at the speed you plan on spraying
and record the time it takes to travel the distance. Read from the chart
or use the formula to fi nd your exact travel speed.
Travel Time (in seconds)
Speed in MPH 200 ft. 300 ft.

5.0 27 41
2. Calculate the required nozzle output. Use either the nozzle wheel (if
nozzle spacing is 20 inches), or this formula:
Formula: Formula:
GPA x MPH x W (in.)
GPM =
5940 5940
GPM =
10 x 7 x 20
= .24 GPM
Note: W= • Nozzle spacing (in inches) for broadcast application.
• Row spacing (in inches) divided by number of nozzles
per row for drop nozzle application.
• Sprayed band width or swath width (in inches) for band
application divided by number of nozzles per band.
• Note that on the nozzle wheel, W = 20 inches.
3. Set correct pressure. Read the required pressure from the nozzle table
in the nozzle catalogue or nozzle wheel. With clean water in the tank
and line, turn on the sprayer and set the target pressure. Collect the
spray from one nozzle for one minute in a container. Adjust pressure
until you collect the precise GPM called for.
30 HARDI® ATV SPRAYER DIAPHRAGM OPERATOR'S MANUAL
Calibration For Carriers Other Than Water
Use the following water rate conversion chart to determine the right
conversion factor. When you've determined the new converted GPM or
GPA, you can follow the steps on either the pressure or ounce method
of calibration.

6.0 MAINTENANCE
IMPORTANT: Always clean the boom at the end of your workday
or
before servicing is done to avoid unnecessary contact with
chem i cals.
In order to derive full benefi t from the sprayer for many years, the following
service and maintenance program should be followed.
6.1 Cleaning The Sprayer
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 disposal of pesticides washings,
mandatory decontamination methods, etc. Contact the appropriate
department, e.g. 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 seepage or
runoff of residue into streams, water courses, ditches, wells, springs, etc.
The washings from the cleaning area must not enter sewers. Drainage
must lead to an approved 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,
e.g. overnight, or until the weather becomes suitable for spraying 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.
Clean sprayers are ready for action.
Clean sprayers can not be damaged by pesticides and their
solvents.
32 HARDI® ATV SPRAYER DIAPHRAGM OPERATOR'S MANUAL
Cleaning the tank
1. Dilute remaining spray liquid in the tank with at least 10 parts of
water and spray the liquid out in the fi eld you have just sprayed.
Note: It is advisable to increase the forward speed (double if
possible) and reduce the pressure. For ISO F110 nozzles,
pressure may be reduced to 22psi (1.5 bar).
2. Select and use the appropriate protective clothing. Select detergent
suitable for cleaning and suitable deactivating agents if necessary.
3. Rinse and clean sprayer and tractor externally. Use detergent if
necessary.
4. Remove and clean tank fi lters and suction fi lters. Be careful not to
damage the mesh. Replace suction fi lter lid. Replace fi lters when the
sprayer is completely clean.
5. With the pump running, rinse the inside of the tank. Remember the
tank roof. Rinse and operate all components and any equipment that
has been in contact with the chemical.
6. After spraying the liquid out again in the fi eld, stop the pump and fi ll
at least 1/5 of the tank with clean water. Note that some chemicals
require the tank to be completely fi lled. Add appropriate detergent
and/or deactivating agent, eg. Washing soda or Triple ammonia.
Note: If a cleaning procedure is given on the chemical label, follow it
closely.
7. Start the pump and operate all controls enabling the liquid to come
in contact with all the components. Leave the distribution valves until
last. Some detergents and deactivating agents work best if left in the
tank for a short period. Check the label.
8. The Self-Cleaning Filter can be fl ushed by removing the bypass
hose from the bottom of the fi lter. Stop the pump and remove the
hose. Start the pump for a few seconds to fl ush the fi lter. Be careful
not to lose the restrictor nozzle.
9. Drain the tank and let pump run dry. Rinse inside of tank, again
letting the pump run dry.
10.Stop the pump. If the chemicals used have a tendency to block
nozzles and fi lters, remove and clean them now. Check also for
sediment on the pressure side of the safety valve for the SelfCleaning Filter.
11.Replace all the fi lters and nozzles and store the sprayer. If, from
previous experiences, it is noted that the solvents in the chemicals
are particularly aggressive, store the sprayer with the tank lid open.
Note: If the sprayer is cleaned with a high pressure cleaner we
recommend lubrication of the entire machine.
33HARDI® ATV SPRAYER DIAPHRAGM OPERATOR'S MANUAL
6.2 Filters
IMPORTANT: Wear protective clothing when servicing & handling
components that have been in contact with spray liquid.
Clean fi lters ensure :
• Sprayer components such as valves, diaphr agms and operat ing unit
are not hindered or damaged during operation.
• Nozzle blockages do not occur while spray ing.
• Long life of pump. A blocked suction fi lter will result in pump
cavit ation.

Poor seals are usually caused by:
• Missing O-rings or gaskets
• Damaged or incorrectly seated O-rings
• Dry or deformed O-rings or gaskets
• Foreign materials
Therefore, in case of leaks; DO NOT overtighten (Fig. 15). Disassemble,
check condition and position of O-ring or gasket, clean, lubricate and
reassemble. For radial type seals (O-ring)(Fig.15) hand tighten only, do
not use pliers.
The O-rings need to be lubricated ALL THE WAY AROUND before fi tting
on to the nozzle tube.

7.0 Off-Season Storage
When the spraying season is over, you should de vote some extra time
to the Spray er. If chem i cal res i dues are left over in the spray er for long
periods, it can reduce the life of the individual com po nents. To pre serve
the sprayer and pro tect the com po nents, carry out the following offsea son stor age pro gram:
1. Clean the sprayer completely - inside and outside - as described
under "Cleaning The Spray er" (section 5.1). Make sure that all
valves, hos es and auxiliary equipment have been cleaned with
de ter gent and fl ushed with clean wa ter afterwards, so no chem i cal
residues are left in the sprayer.
2. Replace any damaged seals and repair any Ieaks.
3. Empty the sprayer completely and let the pump work for a few
minutes. Operate all valves and handles to drain as much water
out of the spraying circuit as pos si ble. Let the pump run until air is
coming out of all the nozzles.
4. Pour in a mixture of ethylene glycol base antifreeze and water at the
ratio for the desired temperature protection (there will be a small
amount of water left in the hoses, pump and bottom of tank). The
volume of the mixture needs to be enough to keep the tank sump full
while the pump is running fl uid through the entire circuit.
5. En gage the pump and op er ate all valves and func tions of the
plumbing system. Spray the spraygun (optional) into the tank until
antifreeze sprays out to make sure the line is full of antifreeze.
Open the distribution valves so the an ti freeze is sprayed through
the nozzles as well. The an ti freeze will also pre vent O-rings, seals,
di a phragms etc. from dry ing out.
6. When the sprayer is dry, re move rust from any scratch es or
damages in the paint and touch up the paint.
7. Lubricate all lubricating points according to the lu bri cat ing scheme
regardless of intervals stated.
8. Re move the glycerine-fi lled pres sure gaug e and store in a vertical
position in frost free con di tions.
9. Apply a thin layer of an ti cor ro sive oil (e.g. SHELL ENSIS FLU ID,
CASTROL RUSTILLO or sim i lar) on all metal parts. Avoid oil on
rubber parts, hoses and tires.
41HARDI® ATV SPRAYER DIAPHRAGM OPERATOR'S MANUAL
