Important Safety Information
Warning signs alert people of automatic gate operation and are required when installing Mighty Mule Automatic 
Gate Operators. A minimum of two WARNING SIGNS must be installed in the area of the gate. Each sign is to be 
visible by persons located on the side of the gate on which the placard is installed.
The operator is intended for installation only on gates used for vehicles. Pedestrians must be supplied with a sepa-
rate access opening. The pedestrian access opening shall be designed to promote pedestrian usage. Locate the gate 
such that persons will not come in contact with the vehicular gate during the entire path of travel of the vehicular 
gate.
We recommend using the GTO Bulldog Pedestrian Gate Lock (Call the GTO Sales Department at 800-543-4283) 
for controlled access.
