Thank you for purchasing a Mighty Mule Gate
Operator—the "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 and watch the enclosed video to ensure
you have the correct system for your particular
needs. Furthermore, this manual and the DVD will
enable you to properly install your Mighty Mule Gate
Operator.
The MM272 Operator is designed for installation on
a pull-to-open dual leaf gates (gates that open into
the property). By purchasing the accessory brackets,
the Mighty Mule Gate Operator can accommodate a
push-to-open dual leaf gates (gates that open out from
the property). The gate must not exceed 12 feet in
length and weigh more than 300 pounds (please see
). The Mighty Mule
Gate Operator can be used on vinyl, aluminum, chain
link, farm tube, and wrought iron gates. 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 operator will obstruct and stop, and may
damage the opener.
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-GATE).
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.
