1. What is a Mighty Mule E-Z Gate Opener?
A Mighty Mule E-Z Gate is a remote controlled automatic gate opener
system. It is the industry leading gate opener for the “Do-It-Yourself”
installer. It is battery operated, low voltage system; it is safe
(no
electrician needed)
, affordable, and easy to install.
2. Is the Mighty Mule Gate Opener Diffi cult to Install?
No. Most installations can be completed easily in two to three hours.
Dual gates will take slightly longer because two operator arms are
required. All installations can be completed with tools commonly used
by most homeowners. Kit includes an installation video and easy to
read instructions. Our technical service team is available to answer any
installation questions. (see box for details.)
3. What Maintenance is required?
All Mighty Mule E-Z Gate Openers are designed to be virtually
maintenance free. However, it is recommended that the push-pull tube
be sprayed once a month with a good grade of “silicone” spray. Do not
use an oil based spray as this will attract sand and dirt.
4. What Happens if the Gate Opener Hits Something?
All Mighty Mule E-Z Gate openers have built-in safety obstruction
sensing which will cause the gate(s) to “Stop” and “Reverse” direction
for two seconds if it comes in contact with an object. If the gate comes
in contact with the object twice (obstructs) before returning to its fully
open or close position, an alarm will sound for fi ve (5) minutes.
5. Can I Manually Open the Gate?
Yes! Each opener arm is mounted to the brackets on the post(s) and
gates with clevis pins and clips. By removing the pin and clip at the
front end, the arm can be removed and the gate can be opened manually.
6. How is a Mighty Mule E-Z Gate Opener Powered?
All Mighty Mule gate openers are low voltage systems with a 12 Volt
battery back up system. This assures limited operation of your gate
during a power outage. The battery can be charged by the transformer,
(included) OR can it be charged by solar panel(s) (optional).
7. How do I Install the Solar Panels?
The Mighty Mule solar panel (FM121) is a complete kit for easy
mounting within 8 ft. (2.4 m) of the control box. If your panel(s) must
be placed farther away than 8 ft. (2.4 m) up to 250 ft. (76.2 m) to receive
maximum sunlight; additional low voltage wiring will be required.
It is important that the solar panels face South and are placed in full
sunlight, away from overhanging trees, or any obstacle that may shade
the panel(s).
8. Will the Mighty Mule Open During A Power
Outage?
Yes. A fully charged FM500 or FM502 battery will provide an average
of fi fty (50) cycles (open and close) and the FM350 battery (12 Volt car
or marine battery not included) provides 1500 cycles during a power
outage. This number can vary depending on factors such as the type of
gate, number of accessories added, and weather conditions if using solar
