E-Z GATE OPENER
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 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). Using an accessory bracket, the Mighty Mule E-Z Gate Opener can accommodate a push-toopen single leaf gate (gates that open out from the property). The gate must not exceed 16 feet in length nor weigh
more than 350 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.
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 for 1 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 16 feet or weighing more than 350 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.

IMPORTANT SAFETY INSTRUCTIONS
Because automatic gate openers produce high levels of force, consumers need to know the potential hazards associated with
improperly designed, installed, and maintained 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.

IMPORTANT SAFETY INSTRUCTIONS
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:
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 safety edges and photo beams provide additional protection against entrapment (see page 5).
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 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 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, spray push pull tube with high quality silicon spray 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 will be around 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

IMPORTANT SAFETY INSTRUCTIONS
Secondary Means of Protection Against
Entrapment
As specified by Gate Operator 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 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 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.
Leading Edge Contact Sensor
on both sides of the gate
Vehicular Gate
Post Edge Contact Sensor
on both sides of the gate
Bottom Edge Contact Sensor
on both sides of the gate
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 or when an object activates the non-contact sensors. 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 (e.g., from a transmitter)
and the gate returns to a fully open or fully closed position.

IMPORTANT SAFETY INSTRUCTIONS
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 augmented protection against entrapment.
Warning Signs

Preparation of the Gate
Step 1
Horizontal Cross Member
The gate must be plumb, level, and swing freely on its
hinges. Wheels must not be attached to the gate. The
gate must move throughout its arc without binding or
dragging on the ground. Note that gates over 250 lb.
should have ball bearing hinges with grease fittings.
Step 2
The fence post must be secured in the ground with
concrete so it will not twist or flex when the opener is
activated. Be sure to position the opener near the
centerline of the gate to keep the gate from twisting and
flexing. The addition of a horizontal or vertical cross
member (if one is not already in place) to provide a
stable area for mounting the gate bracket is also
important.
Vertical Cross Member
11
Installation of Mounting Hardware
The position of the post bracket determines the leverage and efficiency of the opener. The post bracket position also sets the
clearance between the opener and gate in the open and closed positions.
The curved design of the post bracket works well for installations on round and square fence posts. Because the post bracket
carries the entire thrust of the active opener, bolts that completely penetrate the fence post must be used.
On wooden posts, place a metal plate or washer
(not supplied) between the nuts and the fence
post to prevent the thrust of the opener from
pulling the bolts and washers out of the wood.

Metal Plate
NOTE: A fence post smaller than 6" in diameter
or 6" square should be made of metal instead of
wood so that it will remain stable while the
opener is moving the gate.

IMPORTANT:
We strongly recommend using steel pipe, wood or metal to reinforce thin walled tube gates or wood to reinforce panel gates
as shown. These reinforcement methods will prevent damage to the opener and gate when the opener is installed.
Because the size tube gates vary, it is impossible to provide the appropriate reinforcement material for every application. If
you are unable to locate suitable reinforcement materials, call GTO sales at 1-800-543-4283.

Insert the 3/8" x 2" bolt through
the center hole of the post
brackets and post pivot bracket as
shown. Fasten a 3/8" washer and
nut on the end of the bolt. DO
NOT overtighten the nut because
the post pivot bracket will have to
be adjusted later.
NOTE: The following steps are
intended for pull-to-open gate
installations. If you are mounting
your opener on a push-to-open gate
(e.g., a gate on a sloped driveway)
you will need to purchase a Push To

Step 6
Study the 4 1/2" x 4 1/2" setback template (see insert) provided with this manual. Once you are familiar with its
illustrations, cut and save the template from the insert. The template will determine the correct position of the post pivot
bracket before mounting the opener on the fence post.
Remove hairpin, clevis pin, and washer from front mount and close the gate. Rest disconnected opener on cross member of
gate. Stand inside property next to fence post and place one end of template over center of gate hinge. Place the other end of
template over the post pivot bracket hole (either of the two mounting holes in post pivot bracket can be used) where the
opener will be attached. Be sure to hold the template at a 90º angle between these two points and measure 4 1/2" back from
the center of the gate hinge. You will need to rotate the post pivot bracket or the entire post bracket assembly to align it with
the square angle of the template. THE ANGLE BETWEEN THE GATE HINGE AND THE POST PIVOT BRACKET
MUST MATCH THE ANGLE OF THE SETBACK TEMPLATE.
NOTE: If you move the post pivot bracket, be sure one of the post bracket holes is aligned
with the rest of the assembly (the center hole should already have a bolt through it).
Flipping the Post Pivot Bracket gives more position options.
After verifying that you have complied with the 4 1/2" x 4 1/2" setback, insert the 5/16" x 1 3/4" bolt through the aligned
holes of the post bracket and post pivot bracket (illustrated below) and fasten it with the 5/16" washer and nut.
IMPORTANT: If you loosened the clamp on the post bracket to achieve the 4 1/2" x 4 1/2" setback, tighten it in its new
position and recheck the gate bracket with the gate in the open position (move the gate bracket and re-clamp it if necessary).

Installation of the Positive Stops
The positive stops hold the gate firmly in the open and closed positions. The positive stops also form the
boundaries of the gate operating arc and help stabilize the gate. Moreover, a stable gate maintains the long life of
your automatic gate opener system. To further enhance the stability and security of your gate, install the optional
Mighty Mule Automatic Gate Lock® (see Accessory Catalog).
Step 12
Gate Hinge
With the gate at its maximum open position, measure the
distance from the gate hinge to the end of the gate. At
approximately 2/3 of this distance (using the hinge as your
starting point), place a mark on the ground directly under
the gate. Install the open position stop at this mark (see
illustration). The open position stop post may be made of
wood, metal, or concrete and should be firmly secured in the
ground (we recommend setting it in concrete). When the
open position stop post is in the ideal position, the gate will
strike the post just as the opener motor shuts down.
Closed Position Stop Plate

Step 13
Remove hairpin, clevis pin, and washer from front mount
and close the gate (remember to support opener). Fasten the
closed position stop plate to the end of the gate frame on the
gate centerline, but do not tighten it completely. Slide the
stop plate toward the fence post until they touch (see
illustration). Once you have moved the stop plate to the
correct position, tighten its hardware completely.

Setting the Closed Position
Step 18
Reattach the front mountof the opener arm to gate bracket using a clevis pin, washer, and hairpin clip. Press the transmitter
button to activate the opener and determine the degree of gate closure. Initially, the push-pull tube will extend only 7" to 8"
until the stroke adjustment knob is set (see below right). The maximum extension of the push-pull tube is 11 1/2".
Figure A
Moving knob toward
the gate bracket
increases gate closure.
Step 19
To increase the degree of gate closure, loosen the
stroke adjustment knob on the bottom of the
opener housing and move it approximately 1/8"
toward the gate bracket (see Fig. A). Finger tighten
the knob (DO NOT USE PLIERS OR OTHER
TOOLS TO TIGHTEN KNOB). Press the
transmitter button to check your adjustment. To
decrease the degree of gate closure, move the stroke
adjustment knob away from the gate bracket (see
Fig. B).
Stroke Adjustment Knob
Figure B
Moving knob away from
the gate bracket decreases
gate closure.
Step 20
Repeat the procedure in Step 19 until the gate closes firmly as the opener motor shuts down. Each time you adjust the knob,
finger tighten it before pressing the transmitter button to check your adjustment.
If the push-pull tube has been extended too far (i.e., if the knob is too close to the gate bracket), the gate will immediately
reverse and open after closing. When the knob setting is correct, the gate will close firmly, but not sharply, against the
positive stop plate. The motor will run for one-half second after the gate closes against the stop plate. If the motor continues
to run for more than one second, the push-pull tube is overextended and further adjustment is necessary. If the motor strains
too long against the stop plate, the fuse on the control board (above FIRST OPERATOR terminal) will be blown. This
blade-style 15 ampere fuse (sold by most automotive supply stores) can be easily replaced.
NEVER use a fuse rated higher than 15 amperes!

Powering the System
Installation of the Transformer
IMPORTANT:
•
The transformer is designed and intended for indoor use. If the transformer can be plugged only into
an outside electrical outlet, a weatherproof cover or housing (available at local electrical supply stores)
must be used.
•
All low voltage wire used with the Mighty Mule Gate Opener® must be 16 gauge dual conductor,
multi-stranded, direct burial wire (see page 21 and the Accessory Catalog). Do not run more than
1000 feet of wire.
•
If your gate is more than 1000 ft. from an ac power source, you will need to use at least one 5 watt
Solar Panel to charge the battery (see Accessory Catalog). Refer to the Solar Panels and Gate
Activity chart below.
Solar Panels and Gate Activity
The table and map
illustrate the maximum
number of gate cycles
to expect per day in a
particular area when
using one to three GTO
5 watt solar panels (see
Accessory Catalog).
The figures shown are
for winter (minimum
sunlight) and do not
account for the use of any accessory items.
Accessories connected to your system will
draw additional power from the battery.

Step 21
Make sure the power switch is OFF
before proceeding to the next step.
Step 22
Select the electrical outlet into which you
will plug the transformer. Measure the distance
from this outlet to the control box following
the path where the wire will be laid. After you have measured
how much wire is needed, cut the wire to the appropriate length.
20
IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE
The only wire acceptable for use with GTO products is 16 gauge multi-stranded, low voltage, PVC
sheathed wire. This particular gauge enables the transformer to provide an adequate charge through the
control board to the battery at distances up to 1000 ft.
DO NOT use telephone wire or solid core wire. Unlike multi-stranded wire, these types of wire are
inadequate for use with your gate opener system. Telephone wire and solid core wire do not deliver
enough voltage for your gate opener to function and will cause the system to go into a condition known
as "low voltage lockout."
Never splice wires together. Splicing permits corrosion and seriously degrades the wire's ability to carry
an adequate current.
Step 23
Lay the measured length of low voltage wire in a
trench following a path from the selected electrical
outlet to the control box. Wires coming up from the
ground should be run through PVC conduit to protect
them from lawn mower blades, weed eaters, and
grazing animals. Be sure to bury the wire laid in the
trench.

CONTROL BOARD SETTINGS
DIP switches
The four DIP switches on the control board match the opener with the type of gate on which it is
installed. For example, gates may pull-to-open or push-to-open. Prior to packaging, the Mighty Mule
Gate Opener® control board was configured for single swing gates that pull-to-open (open into the
property). If your gate type matches this configuration, you DO NOT need to adjust the DIP switches;
proceed to the Potentiometers section on the next page.
NOTE: To change the DIP switch settings, you must turn the
control box power switch OFF; move the switch; then turn the
power back ON. Use a small screwdriver to move the switches.

Mounting the Receiver
Use the transmitter to check the range of the receiver before permanently mounting it.
Consider the following when mounting the receiver:
• Standard receiver cable length is 10 feet (receivers with a longer cable are available as
special order items; call the GTO Sales Department). NEVER splice receiver cable!
• Run the cable through PVC conduit to protect it from damage.
• DO NOT run cable through metal conduit because the receiver signal range will be
decreased.
• DO NOT run cable in conduit containing ac wiring.
• DO NOT mount receiver on a metal fence or post; doing so will decrease signal range.
• The receiver range can vary from 50 to 100 feet depending upon weather, topography,
and external interference.

reverse within 2 seconds when it comes in contact with an obstruction. However, obstruction sensitivity, even when properly
adjusted, may not be sensitive enough to prevent bodily injury in some circumstances. To augment your protection against
entrapment, GTO suggests using safety edge sensors or photoelectric sensors. When installed, safety edge sensors (or
photoelectric sensors) must be mounted in compliance with UL 325, Underwriters Laboratories safety standard for gate
openers. Review page 5 for information about mounting requirements for safety edges ("contact sensors") and photoelectric
sensors ("non-contact sensors").
Refer to the sensor manufacturer’s instructions for information about installing these devices on a vehicular gate.
Make sure the control box power switch is OFF before connecting safety device wiring to the terminal blocks.

Push to Open Installation
Swinging gates shall not open into public access areas!
A "Push-to-Open" gate opens out from the property.
A Push-to-Open Bracket is required for this type of
installation (see Accessory Catalog). If you have a pull-to-open
gate (gate opens into the property), return to page 13; step 3.
The opener is installed while the gate is in the closed position.
Step PTO-1:
With the gate closed, adjust the post bracket assembly and the gate
bracket until the opener is level. While holding the opener level,
use C-clamps to temporarily keep the post bracket assembly and
gate bracket in their respective positions on the fence post and gate.

Step PTO-2:
While gate is closed, stand inside the property next to the
fence post. Using the setback template (insert) measure
4 1/2" back from center of gate hinge, then make a 90º angle
toward the gate and measure 4 1/2". This is the point where
either one of the holes at the end of the post pivot bracket
should be. You will need to rotate the post pivot bracket or
the entire post bracket assembly to align it with the square
angle of the template.
Round Post
NOTE: If you move the post pivot bracket, be sure that one
of the post bracket holes is aligned with the rest of the
assembly. Flipping the Post Pivot Bracket gives more
position options.
Post Pivot Bracket can be moved to
achieve the 4 1/2" x 4 1/2" dimensions.
After verifying that you have complied with the
4 1/2" x 4 1/2" setback, insert the 5/16" x 1 3/4" bolt through
the aligned holes of the post bracket and post pivot bracket
and fasten it with the 5/16" washer and nut.
29
Step PTO-3:
With the gate in the fully closed position and the opener retracted, swing the opener to the gate. Mark reference points for
bolt holes on gate cross member through middle of gate bracket slots. The opener must be level. (Some vertical adjustment is
possible by sliding the post bracket assembly up and down.) Drill 3/8" holes into the gate cross member as marked. Fasten
gate bracket to cross member using (2) 3/8" x 3" bolts, washers, lock washers, and nuts. Attach the opener to the post bracket
assembly and gate bracket using clevis pins, washers, and hairpins clips.

Stroke Adjustment for Push-to-Open Installation
Step PTO-6:
Figure A
To increase the degree of gate opening, loosen the
stroke adjustment knob on the bottom of the opener
housing and move it about 1/8" toward the gate bracket
(see Fig. A). Finger tighten the knob–DO NOT USE
PLIERS OR OTHER TOOLS TO TIGHTEN KNOB.
Press the transmitter to check your adjustment. To
decrease the degree of gate opening, move the stroke
adjustment knob away from the gate bracket (see Fig B).
Moving knob toward gate
bracket increases gate
opening.
Stroke Adjustment Knob
Moving knob away from
gate bracket decreases
gate opening.
Step PTO-7:
Figure B
Repeat the procedure in step PTO-6 until the gate stops firmly
(but not sharply) against the open position stop plate. The
motor will continue to run for one-half second after the gate
opens against the stop plate. If the motor continues to run for
more than one second, the push-pull tube is overextended and further adjustment is necessary. If the motor strains too long
against the stop plate, the fuse on the control board (above FIRST OPERATOR terminal) will be blown. This blade-style
15 ampere fuse (sold by most automotive supply stores) can be easily replaced. NEVER use a fuse rated higher than 15
amperes!
NOTE: Each time you adjust the knob, finger tighten it before pressing the transmitter button to check your adjustment.

Maintenance & Troubleshooting Guide
If your gate opener does not function properly after it is installed, use this guide before calling the GTO Service Department.
• On all gates weighing 250 lb. or more, routinely grease the ball bearing hinges at least 4 times a year; more
frequently if the gates are near a coastal area.
• Keeping a few mothballs in the control box will discourage insects from entering it and damaging the control
board.
• Clean the push-pull tube with a soft, dry cloth and apply silicone spray to it at least once per month.
If the Opener Does Not Work
Check the Green LED on the Control Board:
IF THE LED IS OFF: This condition indicates a transformer power failure.
1. Test the transformer for voltage with a voltmeter. The acceptable range can be found in the VOLTAGE
LIMITS chart on the next page. If the transformer test shows no voltage, then test the electrical outlet for
voltage. If the outlet test shows voltage, then the transformer is dead and must be replaced. Allow the new
transformer 12 hours to charge the battery before using the gate opener.
2. If the transformer test shows voltage, check the POWER IN terminal block on the control board for voltage.
If the terminal block shows no voltage, look for broken or spliced wires.
Check the Red STATUS LED on the Control Board:
IF THE LED IS ON: but the unit is not working.
1. Check the battery in your transmitter and replace with a fresh one if needed..
2. Verify that the power cable is securely connected.
3. Replace the control board fuse if it is blown (15 ampere fuse only - DO NOT USE
A HIGHER RATED FUSE!).
IF THE LED IS OFF:
1. Make sure the ON / OFF switch at the bottom of the control box is set to ON.
2. Check all connections for looseness and corrosion.
IF THE LED IS FLASHING:
The system may be in a condition known as "low voltage lockout" (i.e., inadequate voltage supplied for the gate opener to
function).
1. Test (using a voltmeter) the voltage output of the transformer (18.0 to 22.0 Vac) or solar panel
(18.0 to 22.0 Vdc) at the control board power terminal block.
A. If the voltage is low or not reading, load test the battery at a electronics store and call your dealer for a
replacement battery if necessary.
B. If the voltage is low or not reading, test the transformer and electrical outlet. Replace the transformer if
necessary and let the battery recharge for 12 hours before using the gate opener.
C. Check the control board for damage or corroded connections.
D. Make sure that telephone or solid core wire is not being used to connect the transformer to the control
board.
31
If the Opener is Working
The Gate CLOSES Then Opens Again on its Own:
1. Check the position of the mounting brackets and readjust if necessary.
2. Check the gate for binding or hinge damage.
3. Check the position of the stroke adjustment knob.

Column Installation Information
IF THIS OPENER WILL BE USED WITH GATES THAT ARE MOUNTED ON
MASONRY, BRICK, OR ROCK (etc.) COLUMNS:
READ THE FOLLOWING CAREFULLY BEFORE PROCEEDING
Attaching a gate opener to a gate mounted on a masonry column requires special procedures.
Here's how to check your installation to minimize problems:
Open the gate to the 90º position, then measure the distance between the back of the gate and the face of
the column. If there is at least a 6 1/4" clearance, you may not have to make any special modifications.
However, you must measure the post pivot bracket position using 4 1/2" x 4 1/2" setback, as described on
page 13 of this manual, to verify that the gate hinge sits far enough from the column to give your
installation the proper setback distance.
If you do not have the proper clearance or setback distance, the opener may operate the gate for a while, but eventually
the unit will become nonfunctional. To prevent this problem, we suggest the following installation method:
A.
The simplest solution is to install the opener in a push-to-open configuration (requires Push-To-Open Bracket,
see Accessory Catalog). The crucial 4 1/2" setback 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 pulling it toward the column. It is
recommended that you place a steel plate between the opener mounting 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!
Because of the difficulty associated with column installations, we STRONGLY advise you to call the GTO
Service Department at (800) 543-1236 or (850) 575-4144 for assistance prior to your installation.
