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 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. - Page 7 IMPORTANT SAFETY INSTRUCTIONS Entrapment Zones: Zone 1 – leading edge of the gate and the fence post. Zone 2 – between the gate and the gate post Zone 3 – the path of the gate Zone 4 – the space between the gate in the open position and any object such as a wall, fence, tree, etc. Zone 5 –...

Installation Overview Pull-to-Open Dual Gate (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 gate. Mounting the openers on masonry columns requires special procedures; see Column Installation Information on page 37 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. The curved design of the post bracket works well for installations on round and square fence posts. Because the post bracket carries the entire thrust of the active opener, bolts that completely penetrate the fence post must be used. -

® • All low voltage wire used with the Mighty Mule Gate Opener must be 16 gauge dual conductor, multi-stranded, direct burial wire (see page 27 and the Accessory Catalog). Do not run more than 1000 feet of wire. - Page 31 IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE The only wire acceptable for use with GTO products is 16 gauge multi-stranded, low voltage, PVC sheathed wire. This particular gauge enables the transformer to provide an adequate charge through the control board to the battery at distances up to 1000 ft. DO NOT use telephone wire or solid core wire.
- Page 32 Step 39 Strip " of insulation from the ends of the low voltage wire. Attach these stripped ends to the transformer terminals; red wire to RED, black wire to BLK. A dab of household petroleum jelly on each terminal will help prevent corrosion. We suggest crimping a spade tongue terminal (not provided) to the end of each wire before attaching it to the transformer.
