MM462 Installation Instructions 3
2. Check Direction of Gate Swing
The Mighty Mule is designed for PULL-TO-OPEN installations.
PUSH-TO-OPEN installations require two Push-To-Open brackets
[FM148]. Push-to-Open Installation Instructions begin on page 19.
3. Prepare the Gates
• Gates must be plumb, level, and swing freely on their hinges.
• Wheels must NOT be attached to the gates.
• The gates must move throughout their arcs without binding or dragging on the ground.
• Note that gates over 250 lb. should have ball bearing hinges with grease fittings.
• The gate post should be be secured in the ground with concrete so it will minimize twist or flex when the opener is
activated.
• The addition of a horizontal or vertical cross member (if one is not already in place) to provide a stable area for
mounting the gate bracket is also important.
• Trench the driveway in order to lay PVC conduit for the second opener power cable (see illustration on page 6).

Gate Grounding
• Shorter wire (6 AWG) is better, 1 to 2 feet recommended.
• Bolt ring terminal at end of cable 4 - 6 inches above ground level.
R4196 Kit Includes:
• Ground Rod Clamp
• 6 AWG Wire (3 feet)
NOTE: No grounding system absolutely protects against lightning strikes.
If installed correctly, a grounding system will help minimize damage to
your gate opener.
