1. READ AND FOLLOW ALL INSTALLATION
INSTRUCTIONS.
2. ALL ELECTRICAL CONNECTIONS TO THE
POWER SUPPLY MUST BE MADE BY A LICENSED
ELECTRICIAN AND MUST OBSERVE ALL NATIONAL
AND LOCAL ELECTRICAL CODES.
3. A separate power-disconnect switch should be located
near the operator so that primary power can be turned off
when necessary.
4. Install the enclosed warning signs on both sides of the
gate. A minimum of two (2) warning signs shall be installed,
one on each side of the gate where easily visible.
5. Never reach between, through or around the fence to
operate the gate.
6. Never connect a button station within reach of the gate or
on the side of the gate operator.
7. Do not adjust the operator controller’s current sensing
feature too high. It should be adjusted high enough to keep
the gate from falsely triggering the sensing, but no
higher than necessary for the gate to operate. DO NOT
DEFEAT THE PURPOSE OF THIS FUNCTION!
8. You must install all required safety equipment.
9. UL325 Compliance requires the use of contact edges or
photoelectric controls on all automatic or remotely-controlled
gate operators.
10. The operator is intended for installation only on gates
used for vehicles. Pedestrians must be supplied with a
separate access opening. The pedestrian access opening
shall be designed to promote pedestrian usage. Locate
the gates such that persons will not come into contact
with the vehicular gate during the entire path of travel
of the vehicular gate.

It’s very important before installing the gate operatorto
make sure the gate slides free and level throughout the
entire opening distance. If the gate does not seem to
operate properly, it may affect the operator performance
or greatly shorten the life of the unit. The gate should also
be designed so that airflow is ample to prevent wind
resistance and drag.
