E-Z GATE OPENERS
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 videotape to ensure you have the
correct system for your particular needs. Furthermore, this manual and the videotape 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 6 feet in length and weigh more than 850 pounds (please see Technical
Specifications on page 10). 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.
PLEASE NOTE—If your application requires any of the following:
Swing gates longer than 18 feet or weighing more than 850 pounds;
Slide gates;
Heavy duty or commercial uses;
Professional installation;
please call GTO at (800) 543-GATE [4283] or (850) 575-0176 for information about our GTO/PRO professional
line of gate openers and accessories. Our Sales Department will be glad to give you the name and phone number of a
GTO/PRO dealer near you.
BEFORE YOU BEGIN TO INSTALL YOUR AUTOMATIC GATE OPENER:
watch the enclosed videotape and read these instructions carefully and completely
to become familiar with all parts and installation steps. The video tape is only designed as
a overview of the installation procedure. You must read the installation manual for detailed
instructions on gate opener safety and proper use of the gate opener.

IMPORTANT SAFETY INSTRUCTIONS
Clevis Pin
Hairpin Clip
Gate Bracket
Front or Rear 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 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.
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.
To Manually Open and Close the
Gate, Follow the Procedure Below:
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.
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.
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 Catalog).

For The Consumer
WARNING: To reduce the risk of injury or death:
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 the 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.
3. Review the operation of the system to become familiar with its safety features. Understand how to disconnect the
opener for manual gate operation (see page 1).
4. This gate opener is intended for vehicular gates ONLY. A separate entrance or gate must be installed for pedestrian
use (see page 6).
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.

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 or post.
II. During Installation
1. Install the gate opener on the inside of the property 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.

IMPORTANT SAFETY INSTRUCTIONS
III. After Installation
1. Attach the warning signs (included) to each side of the gate to alert the public of auto matic gate operation. It is
your responsibility to post warning signs on both sides of your gate. If any of these signs or warning decals become
damaged, illegible or missing, replace them immediately. Contact GTO for free replacements.
2. The gate is automatic and could move at any time, posing a 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 controls 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 opener 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 opener regularly. Grease hinges and replace the battery every 3-5 years.
8. To operate this equipment safely, YOU must know how to disconnect the opener for manual gate operation
(see page 1). If you have read the instructions and still do not understand how to disconnect the opener, contact the
GTO Service Department.
9. Disconnect the opener 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 INSTRUCTIONS 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 in the vicinity of the gate and gate opener are aware of the dangers
associated with automated gates. In the event you sell the property with the
gate opener or sell the gate opener, 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.mightymule.com),
by contacting GTO, Inc., at 3121 Hartsfield Road, Tallahassee, Florida 32303

Secondary Means of Protection Against
Entrapment
As specified by Gate Opener Safety Standard, UL 325 (30A.1.1), automatic gate openers 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® utilizes Type A, an inherent (i.e., built-in) entrapment sensing system as the primary
type of entrapment protection. Also, the Mighty Mule® has provisions for the connection of Type B2 protection to be used
as the secondary type of entrapment protection, if desired.
1. For gate openers 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 opener is not subjected to mechanical damage.
C. A wireless contact sensor such as one that transmits radio frequency (RF) signals to the gate opener for
entrapment protection functions shall be located where the transmission of the signals are not obstructed or
impeded by building structures, natural landscaping or similar obstruction. A wireless contact sensor shall
function under the intended end-use conditions.
ENTRAPMENT ALARM (UL 325; 30A.1.1A)
The Mighty Mule® E-Z Gate Opener is designed to stop and reverse within 2 seconds when the gate comes in
contact with an obstruction. Additionally, these openers 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 until the opener 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 INSTRUCTIONS
1. KEEP CLEAR! Gate may move at any time.
2. Do not allow children to operate gate or
play in gate area.
3. This gate is for vehicles only. Pedestrians
must use a separate entrance.

Required Safety Precautions for Gates
Install Warning Signs
Warning signs alert people of automatic gate operation and are required when installing the Mighty Mule® E-Z Gate
Opener. 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) for controlled access.
Entrapment Protection
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.
Warning Signs
The warning signs (at right) must
be installed on both sides of the
gate (see page 7 for details).
