    Mighty Mule® E-Z Gate® Opener. The Mighty Mule® E-Z Gate® Opener is designed for installation on a pull-to-open dual leaf gate (gates that open into the property). By purchasing an accessory bracket, the Mighty Mule® E-Z Gate® Opener can accommodate a push-to-open dual leaf gate (gates that open out from the property).

  • Page 5: Important Safety Instructions

    IMPORTANT SAFETY INSTRUCTIONS Because automatic gate openers produce high levels of force, consumers need to know the potential hazards associated with improperly designed, installed, and maintained automated gate opener systems. Keep in mind that the gate opener is just one component of the total gate operating system. Each component must work in unison to provide the consumer with convenience, security, and safety.

  • Page 6: Important Safety Instructions For The Consumer

    IMPORTANT SAFETY INSTRUCTIONS For The Consumer WARNING: To reduce the risk of injury or death: READ AND FOLLOW ALL INSTRUCTIONS. Failure to meet the requirements set forth in the instruction manual could cause severe injury and/or death, for which the manufacturer cannot be held responsible. When designing a system that will be entered from a highway or main thoroughfare, make sure the system is placed far enough from the road to prevent traffic congestion.

    Installation Overview Pull-to-Open Gates (Gate Opens into the Property) The diagram shown below is an example of a pull-to-open installation on a chain link fence and dual gates. Mounting the openers on a masonry column requires special procedures; see Column Installation Information on page 38 if you intend to mount the openers on columns.

  • Page 16: Installation Of The Mounting Hardware

    Installation of Mounting Hardware The position of the post bracket determines the leverage and efficiency of the opener. The post bracket position also sets the clearance between the opener and gate in the open and closed positions (minimum 2 inches). The curved design of the post bracket works well for installations on round and square fence posts.
