Please Read This First!

Thank you for purchasing a Mighty Mule Gate 

Operator—Nortek Security and Control's "do-it-

yourself" automatic gate operator! When correctly 

installed and properly used, your Mighty Mule Gate 

Operator will give you many years of reliable service. 

Please read the following information to ensure you 

have the correct system for your particular needs. If 

so, this manual and will enable you to properly install 

your Mighty Mule Gate Operator.
The Mighty Mule Gate Operator is designed for 

installation on a pull-to-open single leaf gate (gates 

that open into the property). The gate must not exceed 

12 feet in length or weigh more than 300 pounds 

(please see Technical Specifications on page x). The 

Mighty Mule Gate Operator can be used on vinyl, 

aluminum, chain link, farm tube, and wrought iron 

gates. 

 Not rated for use on solid surface gates due to 

the potential to damage the operator and/or injure 

someone. 
The Mighty Mule Gate Operator accommodates 

extra transmitters, digital keypads, solar panels, 

push buttons, automatic gate locks, and other access 

control products. These optional accessories (see the 

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 Mighty Mule Sales 

Department (800-543-4283).

The Mighty Mule Gate Operator features Dual Sense 

Technology™. This feature makes the gate stop and 

reverse direction when it comes in contact with an 

obstruction. This is factory set to the most sensitive 

setting and must be adjusted during installation. 
The Mighty Mule Gate Operator 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.
Go to www.mightymule.com for a dealer or retailer 

near you or call (800) 543-4283 for information about 

our Linear professional line of gate operators and 

accessories. Our Sales Department will be glad to give 

you the name and phone number of a Linear dealer 

near you.

BEFORE YOU BEGIN TO INSTALL YOUR AUTOMATIC GATE OPERATOR:

Read these instructions carefully to become familiar with all parts and installation steps. 

The video is only designed as an overview of the installation procedure. 

You must read the installation manual for detailed instructions 

on gate operator safety and proper use of the gate operator.

Clevis Pin

Hairpin Clip

Gate Bracket

Front  Mount

Because automatic gate operators produce high levels 

of force, consumers need to know the potential hazards 

associated with improperly designed, installed, and 

maintained automated gate operator systems. 

Keep in 

mind that the gate operator is just one component 

of the total gate operating system.

 Each component 

must work in unison to provide the end user with 

convenience, security, and safety.

This manual contains various safety precautions and 

warnings for the installer and end user. Because there 

are many possible applications of the gate operator, 

the safety precautions and warnings contained in 

Disconnecting the Operator

1.  Turn control box power switch OFF.
2.  Remove the hairpin clip and clevis pin.
3.  Remove the operator’s front mount from the 

gate bracket.

The gate can be opened and closed manually when the 

operator is disconnected.

this manual cannot be completely exhaustive in 

nature. It does, 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. 

 Warnings in this manual are identified with this 

warning symbol. The symbol identifies conditions that 

can result in damage to the operator or its components, 

serious injury, or death.

MANUALLY OPENING AND CLOSING GATE

Because Mighty Mule automatic gate operators are only part of the total gate operating system, it is the 

responsibility of the installer and end user to ensure that the total system is safe for its intended use.

CAUTION

The gate will move freely and uncontrolled when the gate operator is removed from the gate. ONLY 

disconnect the operator when the control box power switch is OFF and the gate is NOT moving. 

NOTE:

 Substitute a

 Pin Lock

 for the clevis pin on the front mount 

of the gate operator to prevent theft of the operator from the gate (

see 

accessory pages in back of this book).
