Important Safety Information
Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is a
potential hazard to personal safety involved and extra
safety precaution must be taken. When you see this
symbol, be alert and carefully read the message that follows it. In addition to design and configuration of equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence and
proper training of personnel involved in the operation,
transport, maintenance and storage of equipment.
Be Aware of Signal Words
Signal words designate a degree or level of hazard seriousness.
DANGER indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
This signal word is limited to the most extreme situations,
typically for machine components that, for functional purposes, cannot be guarded.
WARNING indicates a potentially hazardous situation
which, if not avoided, could result in death or serious
injury, and includes hazards that are exposed when
guards are removed. It may also be used to alert against
unsafe practices.
CAUTION indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe practices.

Great Plains Manufacturing, Inc. Important Safety Information 3
Handle Chemicals Properly
Agricultural chemicals can be dangerous. Improper use
can seriously injure persons, animals, plants, soil and
property.
▲ Read and follow chemical manufacturer’s instructions.
▲ Always keep hand-wash tank filled with clean water and
have soap available in case of an emergency. Immediately
and thoroughly flush any area of the body that is contaminated by chemicals.
▲ Do not touch sprayer components with mouth or lips.
▲ If persons are exposed to a chemical in a way that could
affect their health, consult a doctor immediately with the
chemical label or container in hand. Any delay could cause
serious illness or death.
▲ If chemical is swallowed, carefully follow the chemical
manufacturer’s recommendations and consult with a doctor.
▲ Wear protective clothing.
▲ Handle all chemicals with care.
▲ Spray only with acceptable wind conditions. Wind speed
must be below 5 mph (8 kph). Make sure wind drift of chemicals will not affect any surrounding land, people or animals.
▲ Before adding chemical to the tank, make sure tank is at
least half full. Do not pour concentrate into an empty tank.
▲ Never leave fill hose attached to the sprayer after filling
tank. Chemicals in tank can siphon out of tank and contaminate freshwater source.
▲ Avoid inhaling smoke from any type of chemical fire.
▲ Rinse out the tank. Spray rinse water on last field sprayed.
▲ Never drain, rinse or wash dispensers within 100 feet (30m)
of a freshwater source, nor at a car wash.
▲ Dispose of empty chemical containers properly. By law
rinsing of the used chemical container must be repeated
three times. Puncture the container to prevent future use. An
alternative is to jet-rinse or pressure rinse the container.
▲ Store or dispose of unused chemicals as specified by chemi-
cal manufacturer.
▲ Wash hands and face before eating after working with
chemicals. Shower as soon as spraying is completed for the
day.

4 3P300 S/N HH1113+ Great Plains Manufacturing, Inc.
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin,
causing serious injury.
▲ Avoid the hazard by relieving pressure before disconnecting
hydraulic lines.
▲ Use a piece of paper or cardboard, NOT BODY PARTS, to
check for suspected leaks.
▲ Wear protective gloves and safety glasses or goggles when
working with hydraulic systems.
▲ If an accident occurs, seek immediate medical attention
from a physician familiar with this type of injury.
Keep Riders Off Machinery
Riders obstruct the operator’s view. Riders could be
struck by foreign objects or thrown from the machine.
▲ Never allow children to operate equipment.
▲ Keep all bystanders away from machine when folding/
unfolding, raising/lowering, transporting, operating, load-
ing and off-loading chemicals.
Use Safety Lights and Devices
Slow-moving tractors and attached implements can create a hazard when driven on public roads. They are difficult to see, especially at night.
▲ Use flashing warning lights and turn signals whenever driv-
ing on public roads.
▲ Use tractor lights.
Check for Overhead Lines
Sprayer markers contacting overhead electrical lines can
introduce lethal voltage levels on sprayer and tractor
frames. A person touching almost any metal part can
complete the circuit to ground, resulting in serious injury
or death. At higher voltages, electrocution can occur
without direct contact.
▲ Avoid overhead lines during sprayer operations.
500-103M-A 09/14/2009
Great Plains Manufacturing, Inc. Important Safety Information 5
Transport Machinery Safely

kph). Some rough terrains require a slower speed. Sudden braking can cause a heavy 3-point load to swerve
and upset the tractor.
▲ Follow your tractor manual recommendations for maximum
hitch loads. See “Specifications and Capacities”on
page 57. Insufficient weight on tractor steering wheels will
result in loss of control.
▲ Do not exceed 20 mph (32 kph). Never travel at a speed
which does not allow adequate control of steering and stopping.
▲ Comply with national, regional and local laws.
▲ Carry reflectors or flags to mark tractor and sprayer in case
of breakdown on the road.
▲ Keep clear of overhead power lines and other obstructions
when transporting. Refer to transport dimensions under
“Specifications and Capacities” on page 57.

Preparation and Setup
This section helps you prepare your tractor, sprayer and
boom for use. Before using the sprayer in the field, you
must hitch the sprayer to a suitable tractor and also setup
the sprayer.
Note: Sprayer setup presumes that the separately-or-
dered boom has already been installed, and all predelivery checks completed. If this is not the case,
contact your dealer for assistance. The boom is not
normally a customer-installed accessory.
Pre-Setup Checklist
1. Read and understand “Important Safety Information” on page 1.
2. Check that all working parts are moving freely, bolts
are tight, and cotter pins are spread.
3. Check that all grease fittings are in place and lubricated. See “Lubrication” on page 50.
4. Check that all safety decals and reflectors are correctly located and legible. Replace if damaged. See
“Safety Reflectors and Decals” on page 7.
5. If removing sprayer from storage, remove any grease
applied to protect cylinder rods (see page 40).
Hitching Tractor to Sprayer
!
DANGER
You may be severely injured or killed by being crushed
between the tractor and sprayer. Do not stand or place any
part of your body between machines being hitched. Stop tractor engine and set park brake before installing hitch pins.
!
WARNING
Be certain that tractor lift capacity is adequate and that tractor is weighted to maintain steering control. Failure to do so
may result in insufficient weight on the steering wheels, and
cause loss of vehicle control. Refer to Tractor Specifications,
“Specifications and Capacities” on page 57. Consult the tractor operator’s manual for tractor weighting recommendations.
Be sure to include the weight of the boom, any material in the
tanks, and all accessories.

Hydraulic Pump Hook Up
The hydraulic motor used on all liquid pumps is a 6 gpm
(23 liter/min.) motor. If the tractor used on the sprayer
does not have the capabilities to adjust the remotes
down to this flow, then a Hydraulic Flow Divider Kit must
be installed so that flow can be controlled to prevent
operating the pump at excessive speeds. See an Great
Plains dealer for more information.
Refer to Figure 5
1. The pressure hose coming out of the tractor remotes
must be connected to the motor inlet port (“I” on current pumps; “A” on older pumps), and the return line
connected to the motor outlet (“O” on current pumps,
“B” on older pumps).
2. Before operating, place a stop in the Neutral position
for the tractor hydraulics so that the hydraulic lever
can only be moved to the float and forward/down
positions. Refer to the tractor’s operator’s manual or
tractor dealer on information for the neutral stop.
Note: DO NOT move the hydraulic lever into the neutral
position while the hydraulic pump is running. To do
so may cause damage to the hydraulic pump.
3. To determine the correct setting of the flow rate, start
out with the hydraulic flow control valve set at a minimum flow for the pair of outlets that operate the
pump.
4. With water in the sprayer tank and in the pump, place
the hydraulic lever in the float position.
5. Open up the sprayer flow control valve to its maximum setting.
6. Start the tractor and engage the pump by placing the
hydraulic lever in the down (forward) position.
7. Once the system builds pressure, close the agitation
valve, shut off the boom section switches, and close
the throttling valves (if applicable).
8. The pump is now at dead head pressure and the
hydraulic control valve must be adjusted so that the
spray pressure reaches 80 PSI maximum on the
nozzle pressure gauge. This process should be done
with the tractor throttle set at normal operating
speed. Mark this setting on the hydraulic control
valve for future reference.
9. Open up the agitation valve and reset the throttling
valves (if applicable). See “Pressure Adjustments”
on page 41.

DANGER
Entanglement hazard - Keep hands, hair, loose clothing, lanyards and feet well away from a rotating PTO drive line. Shut
off tractor completely before hitching, unhitching, or making
any adjustments to or near the PTO.
1. Position the PTO pump on the tractor’s PTO shaft
with the coupler bolt removed on the splined end.
2. Push the coupler of the pump on to align with notch
in the tractor PTO shaft and install bolt.
3. For a 540 RPM pump or a 1000 RPM 1
pump, torque the
ft-lbs.
4. Rotate the PTO shaft by hand to make sure the bolts
clear the PTO shielding.
5. Securely attach the torque bar chain to the tractor
drawbar. Allow just enough slack to permit a full
range of three point hitch operations, such as raising/
lowering, and leveling.
6. Rotate the pump housing in the direction of PTO
rotation, to the full extension of the chain.
7. Hook the tarp strap so that the pump holds the chain
at full extension through the full range of three point
hitch operations. This prevents the torque arm from
snapping the chain to full extension at PTO startup.
8. Tie up any loose hoses with cable ties to prevent
hose damage.
9. With water in the sprayer tank, and water in the
pump, engage the PTO shaft slowly with the tractor
engine idling.

Once the system builds pressure, close the agitation
valve, shut off the boom section switches and close
throttling valves (if applicable). Sprayers with automatic controllers do not have throttling valves. The
pump is now at dead head pressure.
Adjust the engine RPM so that the spray pressure
reaches 80 PSI maximum on the nozzle pressure
gage, or the PTO speed reaches the rated RPM (540
or 1000), whichever is first.
Never exceed the rated tractor PTO RPM. This is the
RPM needed to spray, but without excess pressure
in the sprayer’s plumbing.

DANGER
Entanglement hazard - Keep hands, hair, loose clothing, lanyards and feet well away from a rotating PTO drive line. Shut
off tractor completely before hitching, unhitching, or making
any adjustments to or near the PTO.
1. 540 (rpm) PTO Pump:
Attach the pump to the tractor PTO shaft by tightening the three screwdriver slotted set screws and jam
nuts in the coupler. Make certain the set screws are
in line with the retaining groove on the tractor PTO
shaft.
1000 (rpm) PTO Pump:
Attach the pump to the tractor PTO shaft. Make sure
screwdriver slotted set screws are aligned with
retaining groove on tractor PTO shaft
- BUT DO NOT TIGHTEN.
Next, align the split in the slit-ring locking collar with
corresponding split in the pump drive shaft. Securely
tighten the
collar, then tighten the three slotted head set screws
and jam nuts.
2. To keep the pump body from rotating with the tractor
PTO shaft, affix one end of a torque chain to the
“cold shut” shackle on the pump, and one end to the
tractor.
3. Securely attach the torque bar chain to the tractor
drawbar. Allow just enough slack to permit a full
range of three point hitch operations, such as raising/
lowering, and leveling.
Note: Do not fasten the pump rigidly in position with the
Torque Chain. To do so will cause damage to the
pump. Fasten the pump so that the chain holds the
pump and that there can be slack in the chain.
4. Rotate the pump housing in the direction of PTO
rotation, to the full extension of the chain. If a tarp
strap is available, use it to hold the pump at full chain
extension through the full range of three point hitch
operations. This prevents the torque arm from snapping the chain to full extension at PTO startup.
Ace PTO belt driven centrifugal pumps may be swung to
the bottom, top or either side of the tractor PTO shaft in
order to make it fit a particular tractor. The pump operates satisfactorily in all these positions.

IMPORTANT !
Remember that the discharge port in the volute should
always be at the top (the 12 o’clock or 3 o’clock position) to aid in priming.
