E-Z GATE OPENER
PLEASE READ THIS FIRST!
Thank you for purchasing a Mighty Mule Gate Opener®—GTO's "do-it-yourself" automatic gate opener! When
correctly installed and properly used, your Mighty Mule 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
Gate Opener®.
The Mighty Mule Gate Opener® is designed for installation on a pull-to-open dual leaf gate (gates that open into the
property). Using an accessory kit, the Mighty Mule Gate Opener® can accommodate a push-to-open dual 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 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 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 Gate Opener® features adjustable obstruction sensing. This safety feature makes the gate stop
and reverse direction for 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 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.
To Manually Open and Close
the Gate, Follow the Procedure

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.

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 preforming 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 two (2) 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 provisions for, or be
supplied with, at least one independent primary and 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.

ENTRAPMENT ALARM (UL 325; 30A.1.1A)
The Mighty Mule Gate Opener® is designed to stop and reverse approximately 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 Dual Gates
Install Warning Signs
Warning signs alert people of automatic gate operation and are recommended when installing the Mighty Mule 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.

Preparation of the Gate Leaves
Step 1
Horizontal Cross Member
The gate leaves must be plumb, level, and swing freely
on their 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 gate
leaves weighing over 250 lb. should have ball bearing
hinges with grease fittings.
Step 2
Vertical Cross Member
The fence posts must be secured in the ground with
concrete so they will not twist or flex when the openers
are activated. Be sure to position the openers 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.
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.
Wooden Post
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,
lock 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 dual gate
installations. If you are mounting
your opener on a push-to-open dual
gate (e.g., a gate on a sloped
driveway) you will need to purchase
two (2) Push To Open brackets
(see Accessory catalog). Also, see

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).
The post pivot bracket can be flipped over to give 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).

Mounting the Second Opener
Step 12
Mount the second opener on the remaining gate leaf by repeating Step 3 through Step 11, starting on page 13.
After you have mounted the second opener, proceed to Step 13 on the next page.
16
Installation of the Positive Stops
The Mighty Mule Gate Opener® firmly holds the gate in the open and closed positions against the positive stops.
The positive stops form the boundaries of the gate operating arc and help stabilize the gate leaves. Furthermore,
stable gate leaves help to maintain the long life of your automatic gate opener system. To further enhance stability
and security, we strongly recommended using an optional Mighty Mule Automatic Gate Lock® (see Accessory
Catalog) with your dual gate.
IMPORTANT: You need to determine which side of the driveway you will mount the control box. From this point on
the gate and gate opener on the same side as the control box will be refered to as the MASTER or FIRST gate and gate
opener. The gate and gate opener on the opposite side of the driveway from the control box will be refered to as the SLAVE
or SECOND gate and gate opener.
Step 13
Open position stops are required for both gate leaves
(see illustration at right).
With the gate leaf at its maximum open position, measure
the distance from the gate hinge to the end of the leaf.
At approximately 2/3 of this distance (using the hinge as
your starting point), place a mark on the ground directly
under the gate leaf. 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 leaf will strike the post just as the
opener motor shuts down. Repeat this step for the
other gate leaf.

Attach a vertical closed position stop plate to the SLAVE or SECOND gate.
Remove hairpin clip, clevis pin, and washer from front mount and close the gate leaf (remember to support opener). The stop
plate needs to be positioned near the end of the gate as shown in Illustration A. Position this closed position stop plate
vertically and fasten it to the inside bottom (i.e., SLAVE opener side) of the gate frame, but do not tighten it completely.
NOTE: For a push-to-open installation (gate opens out from the property) attach the closed position stop plate to the outside
of the gate.
Step 15
Install a low profile ground stop (not provided)
beneath the SLAVE gate stop plate.
Mount Vertically
The low profile ground stop may be made of metal or
concrete and should be firmly secured in the ground
(we recommend setting it in concrete). You must
slide the closed position stop plate toward the ground
stop until they touch (see Illustration B at right and
the overview illustration on page 18). Once you
have moved the stop plate to the correct position,
tighten its hardware completely.

Mounting the Receiver
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.
• DO NOT overtighten the mounting screws; the receiver housing could be warped and
the weather seal damaged.
• The receiver range can vary from 50 to 100 feet depending upon weather, topography,
and external interference.

example, a dual gate may pull-to-open or push-to-open.
Prior to packaging, the Mighty Mule Gate Opener®
control board was configured for a single swing gate that
pulls-to-open (opens into the property). You must adjust
the DIP switches so the control board will recognize and
activate both openers. The DIP switches must also be

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).
Figure B
Moving knob away
from the gate bracket
decreases gate
closure.
Step 30
Repeat the procedure in Step 27 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 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!
Step 31
Turn the control box power switch OFF. Disconnect the power cable plug from the coupling of the SLAVE operator with
the gate in the fully closed position (do not disconnect the stripped ends on the power cable from the SECOND
OPERATOR terminal block).
Step 32
Repeat Step 25 through Step 28 to connect the 4-1/2 foot power cable and set the closed position for the MASTER gate
leaf. After you have set the closed position for the MASTER gate leaf, bury the PVC conduit and use the appropriate
material to patch the slot in the driveway.
Step 33
Turn the control box OFF and reconnect the power cable plug and the SLAVE operator. Turn the control box ON and retest
the stroke adjustment and sequencing of your dual gate with both openers activated. Make fine adjustments to the stroke
knob position and set the SEQ1 and SEQ2 DIP switches if necessary. NOTE: Only make changes to the DIP Switches when
the Control Box is turned OFF.

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 27 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 two 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 (at
right) illustrate the
maximum number of
gate cycles to expect
per day in a particular
area when using two 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.

Installation Instructions.
Step 34
Make sure the power switch is OFF
before proceeding to the next step.
Step 35
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.
26
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 36
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.
Step 37
Feed the low voltage wires upward through the strain
relief opening on the lower left of the control box. Pull
6" to 8" of wire into the control box and tighten the
strain relief screw to secure the wires.

Connecting Additional Safety Devices
Although GTO strongly recommends the use of additional safety devices, we
do not endorse any specific brand names. Only use products that are certified
and listed to be in compliance with UL (United Laboratories) and national
and regional safety codes.
Call GTO Sales at 1-800-543-4283 for information on compatible
products for your specific application.
The Mighty Mule Gate Opener® is equipped with built-in obstruction sensitivity. The opener is designed to stop and reverse
the gate approximately 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 4 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.
Insert the safety device wires into the CLS EDG terminal on the FIRST OPERATOR terminal block for the gate closing
mode. Connect the safety device ground wire to the GRN terminal. Connect the safety device wires for the gate opening
mode to the OPN EDG terminal in the same manner.

Push to Open Installation
Swinging gates shall not open into public access areas!
A "Push-to-Open" dual gate opens out from the property.
Two (2) Push-to-Open brackets are required for this type of
installation (see Accessory Catalog).
The opener is installed while the gate leaf is in the closed position.
Step PTO-1:
With the gate leaf 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 leaf 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.
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). The post pivot bracket can be flipped
over to give 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
and fasten it with the 5/16" washer and nut.

Step PTO-3:
With the gate leaf 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.

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) may 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 openers do not function properly after installation, use this guide before calling the GTO Service Department.
• On all gate leaves 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 tubes with a soft, dry cloth and apply silicone spray to them 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 openers.
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: This condition indicates the control board is powered up.
1. Replace the transmitter battery with a fresh one.
2. Verify that the power cables are securely connected.
3. Replace the control board fuses if they are blown (15 ampere fuses only - DO NOT USE
HIGHER RATED FUSES!).
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.
3. Make sure the battery cables are connected.
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.
34
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.
The Gate OPENS Then Closes 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.

Column Installation Information
IF THESE OPENERS 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 14 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 Brackets,
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.
