Please Read This First!
Thank you for purchasing a Mighty Mule® E-Z
Gate Opener—GTO's "do-it-yourself" automatic
gate opener! When correctly installed and properly
used, your Mighty Mule® E-Z Gate Opener will give
you many years of reliable service. Please read the
following information and watch the enclosed video to
ensure you have the correct system for your particular
needs. Furthermore, this manual and the DVD will
enable you to properly install your Mighty Mule® E-Z
Gate Opener.
The Mighty Mule® E-Z Gate Opener is designed
for installation on a pull-to-open single leaf gate
(gates that open into the property). By purchasing
an accessory bracket, the Mighty Mule® E-Z Gate
Opener can accommodate a push-to-open single leaf
gate (gates that open out from the property). The gate
must not exceed 18 feet in length and weigh more than
350 pounds or exceed 8 feet in length and weigh more
than 850 pounds (please see Technical Specifications
on page 9). The Mighty Mule® E-Z Gate Opener can
be used on vinyl, aluminum, chain link, farm tube,
and wrought iron gates. Use on solid (wood) gates
is not recommended. Solid surface gates have a high
resistance to the wind. If the wind is strong enough,
the opener will obstruct and stop.
The Mighty Mule® E-Z Gate Opener accommodates
extra transmitters, digital keypads, solar panels, push
buttons, automatic gate locks, and other access control
products. These optional accessories (see the enclosed
Mighty Mule® Accessory Catalog) are available
at most stores. Your store should be able to special
order any accessory not in stock. If your store cannot
special order accessories, please call the GTO Sales
Department (800-543-GATE).
The Mighty Mule® E-Z Gate Opener features
adjustable obstruction sensing. This safety feature
makes the gate stop and reverse direction within 2
seconds when it comes in contact with an obstruction.
MIN is the factory setting; meaning the gate will exert
the minimum force on an obstruction before it stops
and reverses direction.
The Mighty Mule® E-Z Gate Opener also has an
adjustable auto-close feature. After the gate reaches the
fully open position, it can be set to remain open up to
120 seconds before automatically closing. Pressing the
transmitter button at any time after the gate opens fully
will cause it to close immediately. OFF is the factory
setting; meaning the gate will stay open until you press
the transmitter (or keypad, etc.) again.

Important Safety Information
Clevis Pin
Hairpin Clip
Gate Bracket
Front Mount
Bushing
Because automatic gate openers produce high levels
of force, consumers need to know the potential
hazards associated with improperly designed,
installed, and maintained automated gate opener
systems. Keep in mind that the gate opener is just
one component of the total gate operating system.
Each component must work in unison to provide the
consumer with convenience, security, and safety.
This manual contains various safety precautions
and warnings for the consumer. Because there are
many possible applications of the gate opener, the
safety precautions and warnings contained in this
Disconnecting the Opener
1. Turn control box power switch OFF.
2. Remove hairpin clip, clevis pin, and bushing from
either the front or rear mounting point.
3. Remove the opener from the mount.
The gate can be opened and closed manually
when the opener is disconnected.
manual cannot be completely exhaustive in nature.
They do, however, provide an overview of the
safe design, installation, and use of this product.
CAREFULLY READ AND FOLLOW ALL
SAFETY PRECAUTIONS, WARNINGS, AND
INSTALLATION INSTRUCTIONS TO ENSURE
THE SAFE SYSTEM DESIGN, INSTALLATION,
AND USE OF THIS PRODUCT.
Precautions and warnings in this manual are
identified with this warning symbol. The symbol
identifies conditions that can result in damage to the
opener or its components, serious injury, or death.
Manually Opening and Closing Gate
Because GTO automatic gate openers are only part of the total gate operating system, it is the responsibility
of the consumer to ensure that the total system is safe for its intended use.
CAUTION: The gate will move freely and uncontrolled when the gate opener is removed from the
gate. ONLY disconnect the opener when the control box power switch is OFF and the gate is NOT moving.
NOTE: Substitute a Pin Lock for the clevis pin on the front mount of the
gate opener to prevent unauthorized removal of the opener from the gate
(see accessory pages in back of this book).

1. READ AND FOLLOW ALL
INSTRUCTIONS. Failure to meet the
requirements set forth in the instruction manual
could cause severe injury and/or death, for which
the manufacturer cannot be held responsible.
2. When designing a system that will be entered
from a highway or main thoroughfare, make sure
the system is placed far enough from the road to
prevent traffic congestion.
3. The gate must be installed in a location that
provides adequate clearance between it and
adjacent structures when opening and closing to
reduce the risk of entrapment. Swinging gates
must not open into public access areas.
4. The gate and gate opener installation must
comply with any applicable local codes.
I. Before Installation
1. Verify this opener is proper for the type and size
of gate, its frequency of use and proper class
rating.
2. Make sure the gate has been properly installed
and swings freely in both directions. Repair or
replace all worn or damaged gate hardware prior
to installation. A freely moving gate will require
less force to operate and will enhance the
performance of the opener and safety devices
used with the system (see page 10).
3. Review the operation of the system to become
familiar with its safety features. Understand how
to disconnect the opener for manual gate
operations (see page 2).
4. This gate opener is intended for vehicular gates
ONLY. A seperate entrance or gate must be
installed for pedestrian use (see page 7).
5. Always keep people and objects away from the
gate and its area of travel. NO ONE SHOULD
CROSS THE PATH OF A MOVING GATE.
6. Pay close attention to the diagram below and be
aware of these areas at all times.

II. During Installation
1. Install the gate opener on the inside of the prop-
erty and fence line. DO NOT install an opener
on the outside of the gate where the public has
access to it.
2. Be careful with moving parts and avoid close
proximity to areas where fingers or hands could
be pinched.
3. Devices such as contact sensors (safety
edges) and non contact sensors (photo beams)
provide additional protection against entrapment.
4. If push buttons or key switches are installed, they
should be within sight of the gate, yet located at
least 10 feet from any moving part of the gate
(see diagram below). Never install any control
device where a user will be tempted to reach
through the gate to activate the gate opener.
5. Do not activate your gate opener unless you can
see it and can determine that its area of travel is
clear of people, pets, or other obstructions. Watch
the gate through its entire movement.
6. Secure outdoor or easily accessed gate opener
controls in order to prohibit unauthorized use of
the gate.
For the Consumer
Entrapment Zones for a proper Pull-To-Open installation:
Zone 1 – leading edge of the gate and the fence post.
Zone 2 – between the gate and the gate post.
Zone 3 – the path of the gate.
Zone 4 – the space between the gate in the open position and any object such as a wall, fence, tree, etc.
Zone 5 – pinch points between the opener and gate.

III. After Installation
1. Attach the warning signs (included) to each side
of the gate to alert the public of automatic gate
operation. It is your responsibility to post warning
signs on both sides of your gate. If any of these
signs or warning decals becomes damaged,
illegible, or missing, replace them immediately.
Contact GTO for free replacements.
2. The gate is automatic and could move at any time,
posing serious risk of entrapment. No one should
be in contact with the gate when it is
moving or stationary.
3. Do not attempt to drive into the gate area while
the gate is moving; wait until the gate comes to a
complete stop.
4. Do not attempt to “beat the gate” while the gate is
closing. This is extremely dangerous.
5. Do not allow children or pets near your gate.
Never let children operate or play with gate
controls. Keep the remote control away from
children and unauthorized users; store controls
where children and unauthorized users do not
have access to them.
6. KEEP GATES PROPERLY MAINTAINED.
Always turn power to operator OFF before
performing any maintenance. Clean the
push-pull tube with a soft, dry cloth and apply
silicone spray to it at least once per month.
7. Service the gate and gate operator regularly.
Grease hinges, spray push pull tube with high
quality silicone spray monthly and replace the
battery every 2-3 years.
8. To operate this equipment safely, YOU must
know how to disconnect the operator for manual
gate operation (see page 2). If you have read the
instructions and still do not understand how to
disconnect the operator, contact the GTO Service
Department.
9. Disconnect the operator ONLY when the power
is TURNED OFF and the gate is NOT moving.
10. Make arrangements with local fire and law
enforcement for emergency access.
11. Distribute and discuss copies of the
IMPORTANT SAFETY INFORMATION
section of this manual with all persons
authorized to use your gate.
12. IMPORTANT: Save these safety instructions.
Make sure everyone who is using or will be
around the gate and gate operator are aware of
the dangers associated with automated gates.
In the event you sell the property with the gate
operator or sell the gate operator, provide a
copy of these safety instructions to the new
owner.
Should you lose or misplace this manual, a
copy can be obtained by downloading one from
the Mighty Mule® web site (www.mighty-
mule.com), by contacting GTO, Inc., at 3121
Hartsfield Road, Tallahassee, Florida 32303
or by calling 1-800-543-4283 and requesting a
duplicate copy. One will be provided to you for
a nominal fee.

As specified by Gate Operator Safety Standard, UL
325 (30A.1.1), automatic gate operators shall have an
inherent entrapment sensing system, and shall have
provisions for, or be supplied with, at least one
independent secondary means to protect against
entrapment. The Mighty Mule® 500 utilizes Type A,
an inherent (i.e., built-in) entrapment sensing system
as the primary type of entrapment protection. Also,
the Mighty Mule® 500 has provisions for the connec-
tion of Type B2 protection to be used as the secondary
type of entrapment protection, and is recommended.
1. For gate operators utilizing a contact sensor (e.g.,
safety edge sensor– Type B2) in accordance with
UL 325 (51.8.4 [i]):
A. One or more contact sensors shall be located at
the leading edge, bottom edge, and post edge,
both inside and outside of a vehicular swing gate
system.
B. A hard wired contact sensor shall be located and
its wiring arranged so that the communication
between the sensor and the gate operator is not
subjected to mechanical damage.
C. A wireless contact sensor such as one that
transmits radio frequency (RF) signals to the gate
operator for entrapment protection functions shall
be located where the transmission of the signals
is not obstructed or impeded by building
structures, natural landscaping or similar
obstruction. A wireless contact sensor shall
function under the intended end-use conditions.
Secondary Means of Protection Against Entrapment
ENTRAPMENT ALARM (UL 325; 30A.1.1A)
The Mighty Mule® 500 Automatic Gate Operator is designed to stop and reverse within 2 seconds when the gate
comes in contact with an obstruction. Additionally, these operators are equipped with an audio entrapment alarm which
will activate if the unit obstructs twice while opening or closing. This alarm will sound for a period of 5 minutes, or un-
til the operator receives an intended signal from a hardwired entry/exit source (e.g. push button control or keypad) and
the gate returns to a fully open or fully closed position. Turning the power switch on the control box OFF and back ON
will also deactivate the alarm. Wireless controls such as transmitters and wireless keypads will not deactivate the alarm.

Important Safety Information

Warning signs alert people of automatic gate operation and are required when installing the Mighty Mule® 500
Automatic Gate Operator. Furthermore, a walk-through gate must be installed if pedestrian traffic is expected near
the vehicular gate. We recommend using the GTO Bulldog Pedestrian Gate Lock (Call the GTO Sales
Department at 800-543-4283) for controlled access.
Required Safety Precautions for Gates
Install Warning Signs
GTO’s inherent obstruction settings, even when properly adjusted, may not be sensitive enough to prevent bodily
injury in some circumstances. For this reason, safety devices such as safety edge sensors (or photoelectric
sensors), which stop and reverse gate direction upon sensing an obstruction, are suggested for enhanced protection
against entrapment.
Entrapment Protection
Warning Signs
The warning signs (at right) must be installed on both
sides of the gate (see next page for details).

A. The simplest solution is to install the opener in a
push-to-open configuration (requires push-to-open
bracket, see accessory catalog). The minimum
clearance is easier to achieve and clearance is no
longer a problem, since the opener will be pushing
the gate away from the column instead of pull-
ing it toward the column. It is recommended that
you place a steel plate between the opener mount-
ing brackets and masonry surface for additional
strength.
B. If a push-to-open installation is impossible due to
traffic hazards, terrain, etc., another option is to
re-hang the gate. You may hang it on a post, either
in the center of the column or at the back corner, or
move the gate to the back corner of the columns.
C. The most difficult solution is to cut a notch in the
column to accommodate the opener and power
cable. This job is NOT for the inexperienced!
