ii Diamond Dual Instruction Manual
Thank you for purchasing the Mighty Mule Diamond. When correctly installed and properly used,
your LPA Diamond operators will give you many years of reliable service. Please read the following
information to ensure you have the correct system for your particular needs. This manual will
enable you to properly install your Diamond Automatic Gate Operators.
The Diamond operators are designed for installation on a pull-to-open dual leaf gates. The gates
must not exceed 16 feet in length nor weigh more than 500 pounds* (please see Technical
Specifications on page 1). The Diamond operators 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 operators will
obstruct, stop, and blow fuses.
The Diamond operators accommodates extra transmitters, digital keypads, solar panels, push
buttons, automatic gate locks, and other access control products. These optional accessories
are noted with the
symbol.
The Diamond can be installed on push-to-open gates with the addition of two (2) push-to-open brackets
[FM148].
The Diamond operators feature adjustable stall force. This safety feature makes the gate stop
and reverse direction within two seconds when it comes in contact with an obstruction. The “MIN”
setting means the gate will exert the minimum force on an obstruction before it stops and reverses
direction.
The Diamond operators also have an adjustable auto-close feature. It can be set to remain open
from 3 to 120 seconds before automatically closing. Pressing the transmitter button at any time
after the gate fully opens will cause it to close immediately. “OFF” is the factory setting; meaning
the gate will stay open until you press the transmitter button (or keypad, etc.) again.
Please call LPA at [phone] for more information about our professional line of gate operators
and accessories. Our Sales Department will be glad to give you the name and phone number of a
Mighty Mule dealer near you.
