Read and fully understand the manual.
Contact a trained system technician to maintain and repair the system. (End users should never
attempt to repair the system.)
Retain and utilize the installation/maintenance manual and safety instructions.
Routinely check of all operator functions and gate/door movement.
Discontinue use if safety systems operate improperly, the gate/door is damaged, or the gate/door
is difficult to move.
Never over tighten the operator clutch of load sensing device to compensate for a damaged or stiff
operating system.
Prominently display and maintain warning signs on both sides of the gate/door.
Keep all obstructions clear of the vicinity of the path of the system.
Actively discourage pedestrian use of the vehicular operating system.
Prevent anyone from playing near any part of the system.
Never allow anyone to climb under, over or through a gate or the adjacent fence area.
Never allow children to operate system.
Keep portable controls out of reach of children.
Never allow anyone to install an operating control within reach of the gate/door.
Always be certain that the area is clear of pedestrians before operating the system.
End users should be made aware that they must:
Gate/Door - A moving barrier such as a swinging, sliding, raising lowering, rolling, or like, barrier,
that is a stand-alone passage barrier or is that portion of a wall or fence system that controls
entrance and/or egress by persons or vehicles and completes the perimeter of a defined area.
Vehicular Vertical Pivot-Gate/Door Operator (or System) - A vehicular gate/door operator (or
system) that controls a gate/door that moves in an arc in a vertical plane that is intended for use
for vehicular entrances or exits to a drive, parking lot, or the like.

The operator is intended for installation only on gate/doors used for vehicles.
Pedestrians must be supplied with a separate access opening.
The gate/door must be installed in a location so that enough clearance is supplied
between the gate/door and adjacent structures when opening and closing to reduce the
risk of entrapment. Swinging gates shall not open into public access areas.
The gate/door must be properly installed and work freely in both directions prior to the
installation of the operator. Do not over-tighten the operator clutch to compensate for a
damaged or improperly installed gate/door.
Controls must be far enough from the gate/door so that the user is prevented from
coming in contact with the gate/door while operating the controls. Controls intended to
be used to reset an operator after 2 sequential activations of the entrapment protection
device or devices must be located in the line of sight of the outdoor gate/door or easily
accessible controls shall have a security feature to prevent unauthorized use.
All warning signs and placards must be installed where visible in the area of the
gate/door. A minimum of two placards must be installed.
1)
Install the operator only when:
A)

HOW TO CONNECT POWER (115VAC)
Proper grounding gives an electrical charge, such as from an electrical static discharge or a near lightning strike, a
path from which to dissipate its energy safely into the earth.
Without this path, the intense energy generated by lightning could be directed towards the operator. Although
nothing can absorb the tremendous power of a direct lightning strike, proper grounding can protect the operator
in most cases.
The ground wire must be a single, whole piece of wire. Never splice two wires for the ground wire. If you should
cut the ground wire too short, break it, or destroy its integrity, replace it with a single wire length.
Use the proper type earth ground rod for your local area. In certain circumstances, metal water pipes may be
allowed for grounding the operator. Check and follow all local codes for proper grounding procedures.
Black = 115 VAC Wire
White = Neutral Wire
Green = Earth Ground Wire

• Disconnect power at the fuse box BEFORE
proceeding. Operator MUST be properly
grounded and connected in accordance with
local electrical codes. NOTE: The operator
should be on a separate fused line of
adequate capacity.
• ALL electrical connections MUST be made by
a qualified individual.
• Do not install any wiring or attempt to run
the operator without consulting the wiring
diagram. We recommend that you install an
optional reversing edge BEFORE proceeding
with the control station installation.
• ALL power wiring should be on a dedicated
circuit and well protected. The location of the
power disconnect should be visible and
clearly labeled.
• ALL power and control wiring must be run in
separate conduit.
• BEFORE installing power wiring or control
stations, be sure to follow ALL specifications
and warnings described below. Failure to do
so may result in SEVERE INJURY to persons
and/or damage to operator.
• Entrapment protection devices MUST be
installed to protect anyone who may come
near a moving gate/door.
WARNING: To reduce the risk of SERIOUS INJURY or DEATH:

DO NOT TOUCH ALARM SENSOR
The level of reverse sensitivity has to do with the weight
of the gate and the condition of installation.
Too sensitive = If the gate stops or reverses by itself.
Not sensitive enough = If the gate hits an obstruction or
vehicle and does not stop or reverse.
NOTE: If the power supply to the gate operator is
less than 99 volts, adjust the alarm by turning the
alarm adjustment counter-clockwise enough to
actuate the alarm when obstructed but not sensitive
enough for false triggering to occur.
