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.
Use Adequate Lifting Means
The frame sections and gangs of this machine are
extremely heavy. If using multiple lifters, make sure each
is rated for at least its share of the load.

Prepare for Emergencies
▲ Be prepared if a fire starts
▲ Keep a first aid kit and fire extinguisher handy.
▲ Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone.
11/25/2013 550-466Q
2 8315-8324DVN Great Plains Manufacturing, Inc.
Be Familiar with Safety Decals
▲ Read and understand the “Safety Decals” section of the
Operators Manual.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
Wear Protective Equipment
▲ Wear protective clothing and equipment.
▲ Wear clothing and equipment appropriate for the job. Avoid
loose-fitting clothing.
▲ Because prolonged exposure to loud noise can cause hear-
ing impairment or hearing loss, wear suitable hearing protection such as earmuffs or earplugs.
▲ Because operating equipment safely requires your full
attention, avoid wearing entertainment headphones while
operating machinery.
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 assistance
from a physician familiar with this type of injury.
Use Safety Lights and Devices
Slow-moving tractors and towed 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 lights and devices provided with implement
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 during operation.

Great Plains Manufacturing, Inc. Important Safety Information 3
Shutdown and Storage
▲ Lower implement, put tractor in park, turn off engine, and
remove the key.
▲ Secure Discovator using blocks and supports provided.
▲ Detach and store Discovator in an area where children nor-
mally do not play.
Tire Safety
Tire changing can be dangerous and should be performed by trained personnel using correct tools and
equipment.
▲ When inflating tires, use a clip-on chuck and extension hose
long enough for you to stand to one side–not in front of or
over tire assembly. Use a safety cage if available.
▲ When removing and installing wheels, use wheel-handling
equipment adequate for weight involved.
Safety At All Times
Thoroughly read and understand the instructions in this
manual before operation. Read all instructions noted on
the safety decals.
▲ Be familiar with all machine functions.
▲ Operate machinery from the driver’s seat only.
▲ Do not leave machine unattended with tractor engine run-
ning.
▲ Do not stand between the tractor and machine during
hitching.
▲ Keep hands, feet and clothing away from power-driven
parts.
▲ Wear snug-fitting clothing to avoid entanglement with mov-
ing parts.
▲ Watch out for wires, trees, etc., when folding and raising
machine. Make sure all persons are clear of working area.
