Important Safety InformationBecause automatic gate openers produce high levelsof force, consumers need to know the potentialhazards associated with improperly designed,installed, and maintained automated gate openersystems. Keep in mind that the gate opener is justone component of the total gate operating system.Each component must work in unison to provide theconsumer with convenience, security, and safety.This manual contains various safety precautionsand warnings for the consumer. Because there aremany possible applications of the gate opener, thesafety precautions and warnings contained in thismanual cannot be completely exhaustive in nature.They do, however, provide an overview of thesafe design, installation, and use of this product.CAREFULLY READ AND FOLLOW ALLSAFETY PRECAUTIONS, WARNINGS, ANDINSTALLATION INSTRUCTIONS TO ENSURETHE SAFE SYSTEM DESIGN, INSTALLATION,AND USE OF THIS PRODUCT.Precautions and warnings in this manual areidentified with this warning symbol. The symbolidentifies conditions that can result in damage to theopener or its components, serious injury, or death.Because GTO automatic gate openers are only part of the total gate operating system, it is the responsibilityof the consumer to ensure that the total system is safe for its intended use.Manually Opening and Closing GateCAUTION: The gate will move freely and uncontrolled when the gate opener is removed from thegate. ONLY disconnect the opener when the control box power switch is OFF and the gate is NOT moving.Disconnecting the Opener1. Turn control box power switch OFF.2. Remove hairpin clip, clevis pin, and bushing fromeither the front or rear mounting point.3. Remove the opener from the mount.The gate can be opened and closed manuallywhen the opener is disconnected.Front or Rear MountBushingHairpin ClipClevis PinGate BracketNOTE: Substitute a Pin Lock for the clevis pin on the front mount of thegate opener to prevent unauthorized removal of the opener from the gate(see accessory pages in back of this book).2

Important Safety InformationFor the ConsumerWARNING: To reduce the risk of injury or death:1. READ AND FOLLOW ALLINSTRUCTIONS. Failure to meet therequirements set forth in the instruction manualcould cause severe injury and/or death, for whichthe manufacturer cannot be held responsible.2. When designing a system that will be enteredfrom a highway or main thoroughfare, make surethe system is placed far enough from the road toprevent traffic congestion.3. The gate must be installed in a location thatprovides adequate clearance between it andadjacent structures when opening and closing toreduce the risk of entrapment. Swinging gatesmust not open into public access areas.4. The gate and gate opener installation mustcomply with any applicable local codes.I. Before Installation1. Verify this opener is proper for the type and sizeof gate, its frequency of use and proper classrating.2. Make sure the gate has been properly installedand swings freely in both directions. Repair orreplace all worn or damaged gate hardware priorto installation. A freely moving gate will requireless force to operate and will enhance theperformance of the opener and safety devicesused with the system (see page 10).3. Review the operation of the system to becomefamiliar with its safety features. Understand howto disconnect the opener for manual gateoperations (see page 2).4. This gate opener is intended for vehicular gatesONLY. A seperate entrance or gate must beinstalled for pedestrian use (see page 7).5. Always keep people and objects away from thegate and its area of travel. NO ONE SHOULDCROSS THE PATH OF A MOVING GATE.6. Pay close attention to the diagram below and beaware of these areas at all times.ZONE 1ZONE 2EntrapmentZones for aPush-To-OpenApplicationGate in theOpen PositionZONE 3ZONE 5ZONE 3ZONE 5ZONE 4EntrapmentZones for aPull-To-OpenApplicationDrivewayZONE 4Gate in theOpen PositionZONE 1DrivewayZONE 23

Important Safety InformationFor the ConsumerEntrapment 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.II. During Installation1. Install the gate opener on the inside of the propertyand fence line. DO NOT install an openeron the outside of the gate where the public hasaccess to it.2. Be careful with moving parts and avoid closeproximity to areas where fingers or hands couldbe pinched.3. Devices such as contact sensors (safetyedges) and non contact sensors (photo beams)provide additional protection against entrapment.4. If push buttons or key switches are installed, theyshould be within sight of the gate, yet located atleast 10 feet from any moving part of the gate(see diagram below). Never install any controldevice where a user will be tempted to reachthrough the gate to activate the gate opener.5. Do not activate your gate opener unless you cansee it and can determine that its area of travel isclear of people, pets, or other obstructions. Watchthe gate through its entire movement.6. Secure outdoor or easily accessed gate openercontrols in order to prohibit unauthorized use ofthe gate.Pull-To-OpenApplication10'Push-To-OpenApplication10'10'Moving GateArea10'Moving GateAreaDrivewayNEVER installany control devicewithin gray area10'10'NEVER installany control devicewithin gray areaDriveway10'10'4

Important Safety InformationFor the ConsumerIII. After Installation1. Attach the warning signs (included) to each sideof the gate to alert the public of automatic gateoperation. It is your responsibility to post warningsigns on both sides of your gate. If any of thesesigns 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 shouldbe in contact with the gate when it ismoving or stationary.3. Do not attempt to drive into the gate area whilethe gate is moving; wait until the gate comes to acomplete stop.4. Do not attempt to “beat the gate” while the gate isclosing. This is extremely dangerous.5. Do not allow children or pets near your gate.Never let children operate or play with gatecontrols. Keep the remote control away fromchildren and unauthorized users; store controlswhere children and unauthorized users do nothave access to them.6. KEEP GATES PROPERLY MAINTAINED.Always turn power to operator OFF beforeperforming any maintenance. Clean thepush-pull tube with a soft, dry cloth and applysilicone spray to it at least once per month.7. Service the gate and gate operator regularly.Grease hinges, spray push pull tube with highquality silicone spray monthly and replace thebattery every 2-3 years.8. To operate this equipment safely, YOU mustknow how to disconnect the operator for manualgate operation (see page 2). If you have read theinstructions and still do not understand how todisconnect the operator, contact the GTO ServiceDepartment.9. Disconnect the operator ONLY when the poweris TURNED OFF and the gate is NOT moving.10. Make arrangements with local fire and lawenforcement for emergency access.11. Distribute and discuss copies of theIMPORTANT SAFETY INFORMATIONsection of this manual with all personsauthorized to use your gate.12. IMPORTANT: Save these safety instructions.Make sure everyone who is using or will bearound the gate and gate operator are aware ofthe dangers associated with automated gates.In the event you sell the property with the gateoperator or sell the gate operator, provide acopy of these safety instructions to the newowner.Should you lose or misplace this manual, acopy can be obtained by downloading one fromthe Mighty Mule® web site (www.mightymule.com),by contacting GTO, Inc., at 3121Hartsfield Road, Tallahassee, Florida 32303or by calling 1-800-543-4283 and requesting aduplicate copy.

Important Safety InformationRequired Safety Precautions for GatesInstall Warning SignsWarning signs alert people of automatic gate operation and are required when installing the Mighty Mule® 500Automatic Gate Operator. Furthermore, a walk-through gate must be installed if pedestrian traffic is expected nearthe vehicular gate. We recommend using the GTO Bulldog Pedestrian Gate Lock (Call the GTO SalesDepartment at 800-543-4283) for controlled access.Pedestrian GateBulldog PedestrianGate Lock(recommended, not included)Contact Sensors(recommended, not included)Warning Sign500Vehicular GatePhoto Beams(recommended, not included)Contact Sensors(recommended, not included)Photo Beams(recommended, not included)Entrapment ProtectionGTO’s inherent obstruction settings, even when properly adjusted, may not be sensitive enough to prevent bodilyinjury in some circumstances. For this reason, safety devices such as safety edge sensors (or photoelectricsensors), which stop and reverse gate direction upon sensing an obstruction, are suggested for enhanced protectionagainst entrapment.Warning SignsThe warning signs (at right) must be installed on bothsides of the gate (see next page for details).!7

Before You BeginColumn Installation InformationIF THIS OPENER WILL BE USED WITH GATES THAT ARE MOUNTED ON MASONRY, BRICK,OR ROCK (etc.) COLUMNS, READ THE FOLLOWING CAREFULLY BEFORE PROCEEDINGA. The simplest solution is to install the opener in apush-to-open configuration (requires push-to-openbracket, see accessory catalog). The minimumclearance is easier to achieve and clearance is nolonger a problem, since the opener will be pushingthe gate away from the column instead of pullingit toward the column. It is recommended thatyou place a steel plate between the opener mountingbrackets and masonry surface for additionalstrength.Pivot BracketColumnAB!WARNINGB. If a push-to-open installation is impossible due totraffic hazards, terrain, etc., another option is tore-hang the gate. You may hang it on a post, eitherin the center of the column or at the back corner, ormove the gate to the back corner of the columns.C. The most difficult solution is to cut a notch in thecolumn to accommodate the opener and powercable. This job is NOT for the inexperienced!Column Mount Example(A + B can not exceed 14 inches)Example: If A is 2" then B can not exceed 12"GateMoving Gate Can CauseInjury Or Death1. KEEP CLEAR!
