  7. To operate this equipment safely, YOU must know how to disconnect the operator for manual gate operation (page 
iii). If you have read the instructions and still do not understand how to disconnect the operator, contact the Mighty 
Mule Service Department.
  8. Disconnect the operator 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 operator are aware of the dangers associated with automated gates. In the event you sell the 
property with the gate operator or sell the gate operator, provide a copy of these safety instructions to 
the new owner.

Required Safety Precautions for Gates
Install Warning Signs
Warning signs alert people of automatic gate operation and are required when installing the LPA Gate Operator. The 
Warning Signs included must be installed on both sides of each gate. Furthermore, a walk-through gate must be installed 
for pedestrian traffic. We recommend using the GTO Bulldog Pedestrian Gate Lock  [FM145] for controlled access.
Entrapment Protection
The operator’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.
