BEFORE YOU BEGIN TO INSTALL YOUR AUTOMATIC GATE OPENER:
watch the enclosed video and read these instructions carefully and completely
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 opener safety and proper use of the gate opener.
Thank you for purchasing a Mighty Mule® 352 E-Z Gate Opener—GTO's "do-it-yourself" automatic gate
opener! When correctly installed and properly used, your Mighty Mule® 352 E-Z Gate Opener will give
you many years of reliable service. Please read the following information and watch the enclosed video to
ensure you have the correct system for your particular needs. Furthermore, this manual and the video will
enable you to properly install your Mighty Mule® 352 E-Z Gate Opener.
The Mighty Mule® 352 E-Z Gate Opener
is designed for installation on a pull-to-open dual gate leafs
(gates that open into the property). By purchasing an accessory bracket (FM148), the Mighty Mule®
352 E-Z Gate Opener can accommodate a push-to-open dual gate leafs (gates that open out from the
property). The gates must not exceed 8 feet and 550 pounds or exceed 16 feet and 150 pounds (please
see Technical Specifications on page 10). The Mighty Mule® 352 EZ Gate Opener can be used on vinyl,
aluminum, chain link, farm tube, and wrought iron gates.
The Mighty Mule® 352 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® 352 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® 352 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.

E-Z GATE OPENERS
Use on solid (surface) 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, blow fuses, or may damage the equipment.
