HARDI® GAS ENGINE ESTATE SPRAYER OPERATOR’S MANUAL
Dear Owner,
Thank you for purchasing a HARDI® product and welcome to the everincreasing family of HARDI® equipment owners.
Our sprayers and accessories are rapidly becoming a familiar sight on
North American farms and estates. 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 HARDI® Estate Sprayer were suggested
by growers. There is no substitute for “on farm” experience and we
invite your comments and suggestions.
Please address your correspondence to the Service Manager at one of
these branches:

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
& Stratton or Honda gas engines directly coupled to HARDI® 500 or
600 diaphragm pumps. These sprayers include the ES 50, ES 80, SM
50 and SM 80 models.
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 ES 50 and ES 80 sprayers are equipped with the ET manual
control which features: on/off control for boom and handgun, pressure
adjustment, pump bypass agitation, remote pressure safety valve and
a 2-1/2” pressure gauge.

Estate Sprayers equipped with Briggs
The SM 50 and SM 80 sprayers are equipped with the M600 Brass
manual control which features: on/off control for handgun/(optional
boom), pressure adjustment, pump bypass agitation, integral pressure
safety valve and a 2-1/2” pressure gauge.
The tanks, made of impact proof and chemical resistant polyethylene,
have a purposeful design with rounded contours which allows for
efficient cleaning and draining. They are designed with a large deep
sump so that they can be completely emptied even when the sprayer is
used on slopes. A drain plug is provided in the sump to assist cleaning
of the tank. The tanks are equipped with a top suction filter which can
be inspected and cleaned without emptying the tank.
Also covered in this manual are the 6’ FD and 14’ HD booms which
feature fore and aft breakaways. The 6’ FD boom folds vertically and
the 14’ HD boom folds horizontally forward. Both booms feature ISO
flat fan nozzles with 20” spacing.

are available from your HARDI® Dealer.
NOTE: A Calibration & Nozzles Manual (HARDI® ref. no. 67000103) is
available from your HARDI® dealer which contains more detailed
information for calibration and nozzle selection.
TO USE THE FOLLOWING CHART:
16
1. You must know your desired forward speed (example 3 MPH).
2. You must know the pressure (PSI) you want to spray at (example
30 PSI).
3. You must know your desired application rate (example 16 gallons
per acre).
HARDI® GAS ENGINE ESTATE SPRAYER OPERATOR’S MANUAL
KNOWING THESE THREE FACTS, PROCEED AS FOLLOWS:
1. Locate the correct speed column on the chart below (example 3
M.P.H.).
2. Find the number in that column which is closest to your desired
application rate and is also opposite the desired pressure (example
16.8 GPA is closest to 16 GPA and opposite 30 PSI).
3. For this example, you would select the F-02-110 YELLOW nozzle.
NOTE: Using this chart will bring you very close to your desired application rate. However, for final pressure setting, you must calibrate your
sprayer (Section 6.0).

6.0 CALIBRATION
WARNING:
WATER ONLY! WEAR PROTECTIVE CLOTHING SUCH AS RUBBER GLOVES, GOGGLES AND COVERALLS.
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 large error in application rate.
How do you calibrate a sprayer?
Calibration kits are available from HARDI®, #818493 for U.S. Gallons
and #818492 for metric calibration. For accurate calibration, the
sprayer is driven a specific distance at spraying speed and the length
of time is recorded. The operator then measures the amount of water
sprayed from one nozzle at spraying pressure for the same length of
time noted. The amount of water sprayed provides a direct reading of
application rate. Slight adjustments are then made by varying the
pressure.
Here are some tips to remember when using the calibration kit method:
1. Calibrate with clean water only.
2. Follow the instructions in the calibration kit carefully.
3. Before calibration, check the flow of each nozzle. If it puts out more
than 10% of its original volume, replace it.
4. When determining the length of time required to drive a recommended distance, drive in actual field or lawn conditions with a half full
sprayer. Repeat the test several times, then take the average of the
times recorded.
5. Calibration of the sprayer should be completed at the beginning of
the season and repeated every 2 to 3 full days of spraying, and every
time you change volume rate or use different nozzles.
ALWAYS CALIBRATE YOUR SPRAYER WITH CLEAN
18
NOTE: A Calibration & Nozzles Manual (HARDI® ref. no. 67000103) is
available from your HARDI® dealer which contains more detailed
information for calibration and nozzle selection.
HARDI® GAS ENGINE ESTATE SPRAYER OPERATOR’S MANUAL
6.1 Calibration (Ounce Method)
If you do not wish to use the calibration kit method, the following
method may be used. All you need is a tape measure, stop watch and
a container that accurately measures U.S. fluid ounces.
1. Fill the sprayer tank approximately half full with clean water.
2. Set up two stakes, 204 ft. apart in actual spraying conditions.
3. While driving at spraying speed, note the length of time required to
drive 204 ft. Repeat several times and take the average of the times
recorded.
4. With the sprayer operating at intended spraying pressure, collect the
output from one nozzle for the length of time determined in step 3.
The number of U.S. fluid ounces will exactly measure the application
rate.
e.g. 15 U.S. fluid ounces = 15 U.S. gallons per acre
NOTE: This method only works if the nozzle spacing is 20”.
For conversion to Imperial gallons per acre, multiply U.S. GPA x .833
For conversion to liters per hectare, multiply U.S. GPA x 9.34
For conversion to liters per acre, multiply U.S. GPA x 3.78
7.0 MAINTENANCE
WARNING:
PEOPLE AND ANIMALS. NEVER LEAVE A SPRAYER CONTAINING CHEMICALS WHERE IT COULD BE ACCESSED BY UNAUTHORIZED PEOPLE OR ANIMALS.
IMPORTANT:
before servicing to avoid unnecessary contact with chemicals.
In order to derive full benefit from the sprayer for many years, the
following few, but important rules should be followed.
7.1 Cleaning The Sprayer
Read the entire label of the chemical used. 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.
UNCLEAN SPRAYERS CAN BE HAZARDOUS TO
Always clean the boom at the end of your workday or
HARDI® GAS ENGINE ESTATE SPRAYER OPERATOR’S MANUAL
19
7.1 Cleaning The Sprayer (cont.)
Be familiar with local legislation regarding disposal of agricultural
chemicals, mandatory decontamination methods, etc. Contact the
appropriate office, e.g. Department of Agriculture.
Cleaning starts with calibration as a well calibrated sprayer will ensure
the minimal amount of remaining spray liquid. It is a good practice to
clean the sprayer immediately after use thereby rendering the sprayer
safe and ready for the next application. This also prolongs the life of
the components.
It is sometimes necessary to leave the spray liquid in the tank for short
periods of time (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.
Cleaning
1. Dilute the remaining spray liquid in the tank with at least 10 parts
water and spray the liquid out into the field or lawn you have just
sprayed.
2. Select and use the appropriate protective clothing. Select detergent
suitable for cleaning and suitable deactivation agents if necessary.
3. Rinse and clean sprayer and tractor externally. Use detergent if
necessary.
4. Remove all filters and clean them. Be careful not to damage the
mesh. Replace filters 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 field or lawn, stop the pump
and fill at least 1/5 of the tank with clean water. Note that some
chemicals require the tank to be completely filled. Add appropriate
detergent and/or deactivating agent, e.g. Washing soda or Triple
ammonia.
20
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.
HARDI® GAS ENGINE ESTATE SPRAYER OPERATOR’S MANUAL
8. Drain the tank and let the pump run dry. Rinse inside of tank, again
letting the pump run dry.
9. Stop the pump. If the chemicals used have a tendency to block
nozzles, remove and clean them now.
10. Replace all filters 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.
7.2 Lubrication
Every 40 hours of operation, new grease should be applied to the
pump and boom. Use a high quality multi-purpose lithium based
grease. When greasing the pump, use only 2 to 3 pumps from a
grease gun. For easier application of grease to the boom, place the
wing in the breakaway position. Also oil the M600 control as shown
every 40 hours of operation.

7.3 Nozzle Filters
WARNING:
WITHOUT WEARING CHEMICAL RESISTANT GLOVES AND
SAFETY GOGGLES.
Each nozzle assembly is equipped with a 50 mesh filter screen as
standard. A properly maintained suction filter will eliminate plugging of
the screens and nozzles.
NEVER SERVICE YOUR CONTAMINATED NOZZLES
7.4 Nozzle Tubes and Fittings
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 any fittings (Fig 5).
Disassemble, check the condition and position of the O-ring or gasket,
clean, lubricate and then reassemble. For radial seals (O-ring) (Fig 5),
only hand tighten the fittings. Do not use pliers or wrenches.
The O-rings need to be lubricated ALL THE WAY AROUND before
fitting on to the nozzle.
22
Fig. 5
HARDI® recommends using a vegetable based oil to prolong the life of
the O-ring.
7.5 Pump Maintenance
Changing the valves
Remove valve cover 1 (Fig 6). Before changing the valves 2 (Fig 6),
note the orientation of the valves so that they may be replaced
correctly. It is recommended to use new seals 3 (Fig 6) when changing
or checking the valves.
HARDI® GAS ENGINE ESTATE SPRAYER OPERATOR’S MANUAL
Changing the diaphragms
Remove the diaphragm cover 4 (Fig 6) after removing the valve cover.
The diaphragm 5 (Fig 6) may then be changed. If fluids have reached
the crankcase, re-grease the pump thoroughly. Also make sure the
drain hole at the bottom of the pump is not blocked. Use the following
torque chart when re-tightening bolts:
The 6’ FD boom breakaway should be
adjusted tightly enough so that the boom
stays securely in the upright (folded)
position during transport, yet loosely
enough that the boom easily swings back
if an obstacle is hit. Adjustment is made
by tightening or loosening the spring
tension bolt (Fig 7).

8.0 STORAGE
When the spraying season is over, you should devote some extra time
to the sprayer. If chemical residues are left over in the sprayer for long
periods, it can reduce the life of the individual components. To
preserve the sprayer and protect the components, carry out the
following off-season storage program:
1. Clean the sprayer completely - inside and outside - as described in
Section 7.1 “Cleaning The Sprayer“. Make sure that all valves,
hoses and auxiliary equipment have been cleaned with detergent
and flushed with clean water afterwards, so no chemical residues
are left in the sprayer.
2. Replace any damaged seals and repair any leaks.
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 possible. Let the pump run until air is
coming out of all nozzles.
4. Fill the tank with 3 - 5 gallons of an ethylene glycol base anti-freeze
mixture at the ratio for the desired temperature protection. Run the
pump and circulate the anti-freeze through the distribution valves
and boom lines. Spray the handgun into the tank until anti-freeze
sprays out to make sure the line is full of anti-freeze.
NOTE: Never use diesel fuel in a sprayer.
5. When the sprayer is dry, remove rust from any scratches in the paint
and touch up the paint.
6. Lubricate the boom (Section 7.2).
7. Remove the glycerine-filled pressure gauge and store in a vertical
position in a frost-free environment.
8. To protect against dust, the sprayer can be covered by a tarpaulin.
Ensure ventilation to prevent condensation.

8.1 Preparation After Storage
After a storage period, the sprayer should be prepared for the next
season in the following way:
1. Remove the cover (If fitted).
2. Fit the pressure gauge again. Seal with Teflon tape.
3. Connect the sprayer to the tow vehicle (Section 3.0).
4. Empty the remaining antifreeze into an approved container.
5. Rinse the entire liquid circuit on the sprayer with clean water. Don’t
forget to flush the boom and handgun lines also.
6. Fill with clean water and check all functions (Section 4.0).
