TO THE OWNER
Congratulations on your selection of a Hagie Model GST 20. We recommend that
you study this Operator’s Manual and become acquainted with the adjustments and
operating procedures before attempting to operate your new sprayer. As with any piece
of equipment, certain operating procedures, service, and maintenance are required to
keep it in top running condition.
We have attempted herein to cover all of the adjustments required to fit varying
conditions. However, there may be times when special care must be considered.
Hagie Manufacturing Company reserves the right to make changes in the design and
material of any subsequent sprayer without obligation to existing units.
We thank you for choosing a Hagie sprayer and assure you of our continued interest
in its satisfactory operation for you. If we might be of assistance to you, please call us.
We are proud to have you as a customer.

Most accidents occur as the result of failure to
follow simple and fundamental safety rules. For this
reason, most accidents can be prevented by
recognizing the real cause and doing something
about it before the accident occurs.
Many conditions cannot be completely
safeguarded against without interfering with
efficient operation and/or reasonable accessibility.
Therefore, you must study this Operator’s Manual
4
SAFETY PRECAUTIONS
and learn how to use the sprayer controls for safe
operation. Likewise, do not let anyone operate
without instruction.
Do not make modifications such as
weldments, add-ons, adaptations, or changes from
the original design of sprayer. Such changes and/
or modifications may become safety hazards to
you and to others and will void all warranties.
I. SAFETY/DECALS
DRIVING
• Before moving sprayer, make sure no persons or obstructions are in path of travel.
• Do not permit passengers on sprayer when it is moving; they may fall off or obstruct operator’s
view.
• Never drive near ditches, embankments, holes, mounds, or other obstacles.
• Never drive on hills too steep for safe operation.
• Always drive at a reasonable field speed.
• Reduce sprayer’s speed before turning.
• Come to a complete stop before reversing direction.
• Pull over to side of road before stopping.
• Additional weight caused from partially full or full solution tanks may cause erratic or increased
stopping distance.
• Never operate sprayer on roadway with any solution in solution tank.
• Do not activate parking brake while machine is in motion or damage may occur to sprayer.
• Use flashing/hazard warning lights when traveling on public roads, day or night, unless
prohibited by local law.
• Make sure SMV and SIS emblem is in place and visible from rear when traveling on public
roads.

OPERATING
EDGE LIGHT PLOW
• Make sure personnel are clear of the area when operating the plow.
• Keep the plow in down position when performing maintenance.
GST 20 SPRAY BOOMS
• Cradle booms when leaving sprayer unattended.
• Make sure booms are folded when cradled.
• Select a safe area before unfolding booms. Avoid power lines and overhead
structures.
GENERAL OPERATION SAFETY
• Do not adjust factory engine RPM settings.
• Operate engine at one bump to assure proper charge pressure for brakes to work
properly.
• Start engine from operator’s seat only. Do not by-pass safety-start switch.
• Never use starting fluid to assist engine start up.
• Never run sprayer engine in a closed building. Proper exhaust ventilation is required.
• If equipped with ground speed sensing radar, do not look directly into radar beam. It
emits a very low intensity microwave signal which may cause possible eye damage.

REPAIR/MAINTENANCE
HYDRAULICS
• Use caution when working with hydraulic fluid under pressure. Escaping hydraulic
fluid can have sufficient force to penetrate your skin, causing serious injury. This
fluid may also be hot enough to burn.
• Always lower load or relieve hydraulic pressure before repairing a hydraulic oil leak.
• Avoid torching, welding, and soldering near pressurized hydraulic lines.
FUELING
• Always turn engine off and allow it to cool before refueling.
• Do not smoke while refueling.
• Do not fill fuel tank completely. Fuel may expand and run over.
GENERAL REPAIR/MAINTENANCE
• Turn off engine before checking, adjusting, repairing, lubricating, or cleaning any
part of sprayer.
• When servicing radiator, let engine cool before removing pressurized cap.
• Disconnect battery ground cable and turn main battery switch off before servicing
electrical system or welding on machine.
• When charging battery, connect positive cable to positive terminal and negative
cable to negative terminal. Failure to do so may result in an explosion and cause
injury. Likewise, avoid battery acid contact with body.

CHEMICAL HANDLING
• Never allow chemicals to come in contact with skin or eyes. Wear protective clothing
or respirators as recommended by chemical manufacturer. Store this clothing
outside of the cab so as not to contaminate filtered cab environment. Also, clean
your boots to remove soil or other contaminated particles prior to entering cab.
• Never pour chemicals into an empty tank, fill tank half full of water first.
• Follow chemical manufacturer’s instructions for mixing chemicals.
• Dispose of empty chemical containers properly.
• Wash spilled chemicals or spray residue from sprayer to prevent corrosion and
deterioration.
• Select a safe area to fill, flush, calibrate, and clean sprayer where chemicals will not
drift or run off to contaminate people, animals, vegetation, or water supply.
• Never place nozzle tips or other parts to one’s lips in an attempt to unclog spray tip.
• Do not spray when wind is in excess of chemical manufacturer’s recommended
speed.
• Store pesticides in their original containers with label intact. Keep them in a
separate, locked building.
I. SAFETY/DECALS
GENERAL SAFETY
• Keep a fire extinguisher close at all times.
• Keep all shields in place.
• Keep clear of all moving parts and keep others away when operating.
• Do not wear loose fitting clothing that may be blown or drawn into moving parts.

WARNING DECALS
Decals warning you of avoidable danger are
located on various parts of the sprayer. They are
there for your personal safety and protection. DO
NOT remove them. They will fracture upon at-
tempted removal and therefore must be replaced.
Following are locations of important safety
decals. Replace them if they are torn or missing. All
warning decals and other instructional Hagie decals
or machine striping may be purchased through Hagie
Customer Support Department. To replace decals,
be sure the installation area is clean and dry; decide
on exact position before you remove the backing
paper.

II. IDENTIFICATION NUMBERS
SPRAYER IDENTIFICATION
Each Hagie sprayer is identified by means of a
frame serial number. This serial number denotes
the model, year in which it was built, and the
number of the sprayer. For further identification, the
engine has a serial number, the hydrostatic pumps
have serial numbers, the wheel motors have
identification tags, and the planetary hubs have
identification plates that describe the type of mount
and gear ratio. To ensure prompt, efficient service
when ordering parts or requesting service repairs
from Hagie Manufacturing Company, record the
serial and identification numbers in the space
provided below.
