Mighty Mule 362-D Installation Instructions 

rev 12-14-15

IMPORTANT SAFETY INSTRUCTIONS

  7.  To operate this equipment safely, YOU must know how to disconnect the opener for manual gate operation (page 

iii). If you have read the instructions and still do not understand how to disconnect the opener, contact the GTO 

Service Department.

  8.  Disconnect the opener 

ONLY

 when the power is 

TURNED OFF 

and the gate is 

NOT 

moving.

  9.  Make arrangements with local fire and law enforcement for emergency access.
  10.  Distribute and discuss copies of the 

IMPORTANT SAFETY INSTRUCTIONS 

section of this manual with all 

persons authorized to use your gate. 

 11.

 IMPORTANT: Save these safety instructions. Make sure everyone who is using or will be around the gate 

and gate opener are aware of the dangers associated with automated gates. In the event you sell the 

property with the gate opener or sell the gate opener, provide a copy of these safety instructions to the 

new owner. 

 

  Should you lose or misplace this manual, a copy can be obtained by downloading one from the Mighty 

Mule web site (www.mightymule.com), by contacting GTO Access Systems, LLC., at 3121 Hartsfield Road, 
Tallahassee, Florida 32303 or by calling 1-800-543-4283 and requesting a duplicate copy. One will be provided 
to you free of charge.

Required Safety Precautions for Gates

Install Warning Signs

Warning signs

 

alert people of automatic gate operation and are 

required 

when installing the Mighty Mule Gate Opener.  

The Warning Signs included must be installed on both sides of each gate. Furthermore, a walk-through gate must be 

installed if pedestrian traffic is expected near the vehicular gate. We recommend using the GTO Bulldog Pedestrian Gate 

Lock [FM145] (page 26) for controlled access.

Entrapment Protection

GTO’s inherent obstruction settings, even when properly adjusted, 

may not be sensitive enough to prevent bodily 

injury in some circumstances. 

For this reason, safety devices such as safety edge sensors (or photoelectric sensors), 

which stop and reverse gate direction upon sensing an obstruction, are suggested for enhanced protection against 

entrapment.
