GATE OPERATOR
CLASSIFICATIONS
All gate operators can be divided into one of four different
classifications, depending on their design and usage.
Class I Residential Vehicular Gate Operator
A vehicular gate operator intended for use in a home of one to
four single family dwellings, or garage or parking area associated with these dwellings.
Class II Commercial / General Access Vehicular Gate
Operator
A vehicular gate operator intended for use in a commercial
location or building such as a multifamily housing unit of five
or more single family units, hotel, retail store or other building
servicing the general public.
Class III Industrial / Limited Access Vehicular Gate
Operator
A vehicular gate operator intended for use in an industrial
location or building such as a factory or loading dock area or
other location not intended to service the general public.
Class IV Restricted Access V ehicular Gate Operator
A vehicular gate operator intended for use in a guarded industrial location or building such as an airport security area or
other restricted access locations not servicing the general
public, in which unauthorized access is prevented via supervision by security personnel.
IMPORTANT!!
Before installing the gate operator , make sure the gate’s swing
is free and level throughout the entire swing path. 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 be designed so that airflow is ample to prevent wind
resistance and drag.
SAFETY INFORMATION
AND WARNINGS
Read the following before beginning to install OSCO swing
gate operators:
1. Read the orange “Safety Instructions” brochure enclosed
with the packet of information. If you do not have one,
please call OSCO at 1-800-333-1717 to request one. Read
and follow all 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. Each sign must be plainly visible from the side of
the gate on which they are mounted.
5. Never reach between, through or around the fence to
operate the gate.
6. Y ou must inst all all required safety equipment.
PRE-INSTALLATION
INFORMATION
Before unpacking, inspect the carton for exterior damage. If
you find damage, advise the delivery carrier of a potential claim.
Inspect your package carefully. You can check your
accessory box parts with the enclosed packing slip for your
convenience. Claims for shortages will be honored for only 30
days from the date of shipment.
Before installing the operator, read this manual completely
to ensure all requirements for proper installation are present.
Verify that the volt age to be used matches the voltage of the
operator.

SWG OPERATOR INSTALLATION GUIDE
WIRING SPECIFICATIONS
1. Select from the chart at the bottom of this page corresponding to the
model, voltage and horsepower rating of your operator.
2. The distance shown on the chart is measured in feet from the operator to the power source. DO NOT EXCEED THE MAXIMUM DIS-
TANCE. These calculations have been based on standard 115V and
230V supplies with a 10% drop allowable. If your supply is under the
standard rating, the runs listed may be longer than what your application will handle, and you should not run wire too near the upper
end of the chart for the gauge of wire you are using.
3. When large-gauge wire is used, a separate junction box (not supplied) may be needed for the operator power connection.
4. All control devices are now 24VDC, which can be run considerable
distances. 24VAC is available for other devices, such as loop detectors and photo eyes.
5. Wire run calculations are based on the National Electrical Code, Article 430 and have been carefully determined based on motor inrush,
brake solenoids, and operator requirements.
USE COPPER WIRE ONLY!
6. Connect power in accordance with local codes. The green ground
wire must be properly connected.
7. Wire insulation must be suitable to the application.
8. Control wiring must be run in a separate conduit from power wiring.
Running them together may cause interference and faulty signals in
some accessories.
9. Electrical outlets are supplied in all 115VAC models for convenience
with occasional use or low power consumption devices only. If you
choose to run dedicated equipment from these devices, it will decrease the distance for maximum run and the charts will no longer be
accurate.
10. A three-wire shielded conductor cable is required to connect master
and slave operators. Y ou must use Belden 8760 T wisted Pair Shielded
Cable (or equivalent) only – OSCO part number 2500-1982, per
foot). See page 10 for details of this connection, as well as dip
switch selection. Note: The SHIELD wire should be connected
in both the master and slave operators.

POST MOUNTING INSTRUCTIONS FOR MODEL SWG
NOTE: Maximum gate opening
angle is approximately 95 degrees,
depending on gate width. If larger
opening angle is required, nonstandard positioning of the operator and modified articulating arms
will be required. Contact the factory for pricing and availability.

Use two 3 - 3 1/2” diameter galvanized posts and secure with concrete
footings as shown, length to be determined by local codes, frost line
depth, and soil conditions.
Attach the operator with the U-bolts, side plates and hardware provided. There are four side plates. The 3/16” side plates go on the inside top of the operator, while the two 1/2” side plates go on the inside
bottom (see the illustration at right). The operator should be positioned
at a level to allow the arm to be installed at mid-height on the gate. “H”
dimension can vary depending on gate construction. Make sure the
posts do not protrude above the operator cabinet.
Assemble the arm components as shown on page 7.

STRING METHOD FOR NONSTANDARD INSTALLATION OF SWING GATE OPERATORS
Step A: Position the Operator
1. Connect the gate plate assembly onto the gate at the recommended
location for a standard installation (Dimension “W”).
2. Open the gate to its fully-open position.
3. Position the operator parallel to the gate. The distance from the operator
output shaft to the gate plate pivot point is shown at right. The operator
should be positioned the same distance from the gate hinge as the gate
plate has been; ie: the “W” dimension.
Step B: Measure the Crank Extension and Link Center to Center
Distances
1. Close the gate.
2. Using a piece of tape, attach a string to the top of the operator output
shaft, at its center. Holding the string taut and using another piece of
tape, hold the other end of the string across the hole in the gate plate.
This distance is Dimension 1. Carefully measure this dimension and
write it down.
3. Open the gate.
4. Pick up the string, while it is still attached at both ends, and pull it taut
again while positioning it directly over the center of the operator shaft, at
Point “B,” and work your way back along the string until you reach Point
“C.”
5. While holding the string taut, measure the distance from Point “B” to
Point “C.” This is the required center to center distance for the crank
extension.
6. Measure the distance from Point “A” to Point “C.” This is the required
center to center distance for the link section.
7. When added together, the distances from Point “A” to Point “B” and
Point “B” to Point “C” should equal the Dimension 1 measurement.
DOOR MUST
FACE A WA Y
FROM
DRIVEWAY
These measurements will be needed when placing an order for special
length crank extensions and links. Also note that the measurements you
have just calculated are center to center only , and are not overall dimensions, which would also include other attachment hardware, such as gate
arm clamps.
It is also possible that both open and closed limit switches may be activated at either end of gate travel due to the total gate travel required, and
the shape of the limit switches and cams. This problem can be corrected
by carefully bending the limit switch arm slightly and readjusting its cam.
PLEASE NOTE: Y our operator may look different when installed.

SWG OPERATOR INSTALLATION GUIDE
VENT PLUG INSTALLATION
Gear reducers used in OSCO gate operators will have solid plugs installed prior to shipment in order to keep the oil inside from
spilling out during shipping. A vent plug has been provided to replace this plug during installation. This plug will look similar to the
ones shown below. Some models may have a vent plug with a breather pin. This pin should be removed after installing the
operator.
OR
TORQUE LIMITER ADJUSTMENT
Before adjusting the torque limiter, make sure the gate is in
good working condition. One person should be able to move
the gate by hand. Be certain the gate moves freely and without binding throughout its travel. Torque limiters are set light
at the factory . They must be adjusted during installation, preferably after limit cams have been manually set (see page 9).
Adjust the torque limiter tight enough to keep it from slipping
during normal operation.
To adjust the torque limiter in model SWG:
1. Bend the locking tabs away from the adjustment nut.
2. To increase the output , turn the adjustment nut clock-
wise one flat, or 1/6 turn, at a time until desired output is
obtained.
To reduce the output, turn the adjustment nut counterclockwise one flat, or 1/6 turn, at a time until desired
output is obtained.
3. Bend the locking tabs up to lock the adjustment nut in
place.

SWG OPERATOR INSTALLATION GUIDE
ELECTRICAL CONNECTION AND ADJUSTMENTS
Power supply must be of correct voltage and phase.
Always disconnect power from operator before servicing.
Keep clear of gate during operation.
All OSCO gate operators are supplied with a power disconnect switch to turn on and off the power supply available to the
operator. Incoming power should be brought into the operator and connected to the labeled pigtails in the disconnect box,
following wiring specifications on page 4. A wiring connections print can be found on the inside cover of the operator .
Proper thermal protection is supplied with the operator. The motor contains a thermal overload protector to protect from overheating the motor due to overload or high-frequency operation. This overload will reset automatically after the motor cools down.
LIMIT CAM ADJUSTMENTS
The limit cams are not preset at the factory and must be adjusted for the length and opening angle of the gate the operator is
installed on. The limit switches are activated by a series of rotating limit cams which are attached to the drive shaft. The operator
has also been preset in the right hand operation mode. If the installation requires left hand operation a dip switch must be flipped
(see page 10).
With the gate connected to the gate operator in a mid-travel position, the power disconnect switch turned OFF, and the torque
limiter set loose enough to slip freely , manually move the gate to its fully open position.
Once the gate is in the fully open position, adjust the limit cam for open direction. Set the LSO-1 limit cam so that it has just
triggered its switch.
Once the open limit cam is set, repeat the above process for the close direction, LSC-1.
After finishing the initial limit cam adjustments, reposition the gate to approximately the center of travel. At this time, adjust the
torque limiter as explained on page 8. Turn the power disconnect switch ON, stand clear of any moving parts and press the
OPEN button. Observe the gate as it runs through a complete cycle in both directions, and adjust your limit s again if necessary .If
the operator stops during travel, you may need to adjust the open or close current sensor adjustment or the maximum run timer
(see page 12).
