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 Vehicular 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.
LIMITED TWO-YEAR WARRANTY
This electric operator is warranted for a period of two (2)
years from date of sale against defects in materials or
workmanship. Defective part(s) shall be repaired or replaced at no charge, at the manufacturer’s option. All
accessories are covered by their manufacturer’s warranty.
The manufacturer will not be responsible for transportation and/or field service charges.
The above warranty is in lieu of all other warranties, expressed or implied, and shall be considered void if visible
evidence implies recommended installation procedures
and maintenance instructions were not followed, or if the
electric operator was not sized appropriately for the particular installation.
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. You must install 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 voltage to be used matches the voltage of the
operator.
The following contact or non-contact obstruction detection devices have been approved for use with
OSCO swing gate operators as part of a UL325 compliant installation:

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 DISTANCE. 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.
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. You must use Belden
8760 Twisted 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.

FROM
DRIVEWAY
Post Mounting Instructions
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 eight side plates; four go on the
outside of the operator, and the remaining four go on in
the inside. 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.
A SEPARATE PEDESTRIAN GATE IS REQUIRED FOR
ALL PEDESTRIAN TRAFFIC. THIS GATE MUST BE
A MINIMUM DISTANCE OF 7 FEET FROM THE
VEHICULAR GATE AND GATE OPERATOR

Pad Mounting Instructions
Recommended pad size is 32”x19”x18” deep minimum.
Pad depth should be set according to local codes and
at least as deep as frost line. If soil conditions may cause
operator and pad to shift during operation, anti-rotation
legs may be required. Use two 6” diameter, 10” deep
legs to counteract this problem as shown. 5/8” J-bolts
may be set into the concrete before it sets following the
dimensions shown, or drilled after the concrete sets.
Attach pad mounting brackets to the operator with 3/8”
hardware provided. Use 5/8” hardware to mount the
operator to the pad.
Dimensional data for conduit knockouts is also shown
in the pad mount illustration. Use of flexible conduit will
make it easier to line up with these knockouts.
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 AWAY
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: Your operator may look different when installed.

MSG-A • MSG-D 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 Models MSG-A and MSG-D:
1. Loosen the setscrew in the adjustment nut.
2. To increase the output, turn the adjustment nut clockwise 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 is obtained.
3. Tighten the setscrew when finished.

MSG-A • MSG-D 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 limits 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).

Auto Close Timer Adjustment: This 270-degree adjustable potentiometer will signal the operator to close automatically,
provided no open, reversing or obstruction signals are present from the fully-open position. This timer is adjustable from 0 to 124
seconds. This feature is turned on or off using dip switch #1.
Maximum Run Timer Adjustment: This 270-degree adjustable potentiometer will signal the operator to stop running once it
counts down, unless a limit switch is reached or an input is received first. Each time the motor starts, this timer will begin
counting. This timer is adjustable from 15 to 100 seconds. If the timer expires, the unit locks out and the emergency alarm
sounds.
Open Direction Current Sense Adjustment: This multiturn potentiometer is used to calibrate the built-in current sensing
feature for detection of obstructions while running in the open direction.
Close Direction Current Sense Adjustment: This multiturn potentiometer is used to calibrate the built in current sensing
feature for detection of obstructions while running in the closed direction.
Master/Slave Connection Block: This terminal block is used in conjunction with two operators to configure two gates to open
and close together.
Dip Switches:
#1 This switch turns the auto close timer off/on.
#2 This switch is used in conjunction with alarms and flashing lights that may be added to the operator. When the switch is
in the ON position, these devices will start approximately two seconds prior to the operator starting. In the OFF position,
the devices will only work while the operator is running.
#3 This switch is used in conjunction with single-button controls and radio receivers. In the ON position, successive inputs
will cause signals in the order of OPEN-STOP-CLOSE-STOP. In the OFF position, inputs will cause an OPEN signal
unless the gate is fully open, in which case it will signal CLOSE.
#4 This switch determines right-hand vs. left-hand behavior. When looking from inside the protected area toward the gate, the
side of the drive the operator is on determines its hand of operation. In the OFF position, the operator is set for right-hand.
#5 When turned ON, this switch will allow a one-second delay for solenoid locks to unlock before the motor starts.
#6 In the ON position, this switch will disable the inherent DC brake in DC operators only. In addition, the R2 brake resistor
on the DC motor board must be cut from the board (refer to the picture above). In the OFF position, the DC brake will
function.
#7 Not used at this time.
#8 This switch is used to set Master/Slave configuration. Operators which are stand-alone or master units should be set to
OFF, while only slave units should have this switch set to ON.

the gate again. Should the gate be restarted and the signal occur again prior to
reaching a limit, the gate will stop again, and this time will sound the emergency
alarm and lock out.
work in the closing direction.
This is typically used with a loop and loop detector to keep a large swing gate
open while vehicular traffic is passing through.
Depending on dip switch #2, these devices will either begin two seconds before the
operator starts, or only while the motor is running. (See page 10 for details.)
Never connect a button station within reach of the gate or on the side of the gate operator.
Do not adjust the circuit board 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

MSG-A • MSG-D OPERATOR INSTALLATION GUIDE
CURRENT SENSING ADJUSTMENTS
Because gates vary in construction and may have different force requirements in the open and close directions to move, the
OSCO control board has separate Multi-turn potentiometers for adjusting in both directions independently. The adjustment
should be set light enough to maintain minimal force (40 lbs.) should an obstruction occur, but high enough to keep the gate
moving under normal conditions without interruption.
Prior to adjusting the operator current sensing functions, make sure the gate moves freely in both directions. A badly aligned or
poorly maintained gate may cause false triggering of the current sensor. Refer to page 10 when following the instructions below.
A factory adjustment tool has been supplied to make these adjustments easier. This tool has been taped to the control box for
your convenience.
CLOSE DIRECTION CURRENT SENSE ADJUSTMENT
When the gate operator leaves the factory, it has been preset for a relatively light gate function and will require additional
adjustment. Begin by starting the gate going closed. If the operator stops and reverses, turn the close direction potentiometer
(see page 10) one turn higher, press the STOP button, and try again. Repeat this process until the gate no longer causes false
tripping of the current sensor. Note that each time the gate operator reverses, the STOP button must be pressed. Next, turn the
close direction potentiometer lower slowly while the operator is running the gate closed until the gate operator stops and
reverses again. From this point, turn the close direction potentiometer higher by 1 1/2 turns for all 115 Volt AC and 24 Volt DC
operators, and by 3/4 of a turn higher for all 230 Volt AC operators.
OPEN DIRECTION CURRENT SENSE ADJUSTMENT
Repeat the same process with the open direction potentiometer while running the gate in the open direction. Once this is done,
run the gate through several complete cycles and make sure the gate does not false trip in either direction.
Multi-turn Potentiometer
Remember it is important not to set the adjustment
too high! Doing so will defeat the purpose of the current sensing as an obstruction detecting feature.
MAXIMUM RUN TIMER ADJUSTMENT
This adjustable potentiometer sets the maximum length of time
the motor will run before shutting down. It should be configured
for the time it takes to run the gate fully open or closed, plus an
additional 15 seconds. See page 10 for details.
AUTO CLOSE TIMER ADJUSTMENT
This adjustable potentiometer sets the length of time which
elapses before the gate operator automatically closes the gate,
from the fully open position, provided no open, reversing, or
obstruction signals are present. This feature can be turned on or
off via dip switch selection. See page 10 for details. Do not use
the auto close timer without an appropriate reversing device
installed!
BATTERY BACK-UP
FOR DC MODELS ONLY
CHARGER BOARD CONFIGURATION
To set the voltage monitor, see the picture below. The RUN position will monitor the voltage of the battery only after AC voltage has
been interrupted. It will allow the operator to continue to function
until the batteries have dropped to 17 volts. When the batteries
have reached 17 volts, the operator will open and shut down until
AC power has been restored. In the OPEN ONLY position when
AC power has been interrupted the operator will open and shut
down until AC power is restored.
Note: If the charger board is set to open only, removing incoming
power will cause the operator to run to full open position. Turn off
power switch in operator before removing incoming power!
MASTER/SLAVE CONNECTION
A three-wire shielded conductor cable is required to connect master and slave operators. You must use Belden 8760 Twisted
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. In addition,
you must run power to both the master and slave operators.

IMPORTANT NOTES FOR INSTALLATION OF
MASTER/SLAVE APPLICATIONS
When setting up Master/Slave gate operators, it is best to make adjustments and run each operator individually. To do this,
simply:
a. Set Dip Switch #4 to proper hand of operation (right-hand or left-hand)
b. Set Dip Switch #8 as Master (off)
Run each operator making current sensing adjustments as necessary, as indicated on the Control Board Adjustments page of
this installation guide. When both operators have been adjusted, turn power off, then turn on Dip Switch #8 in the operator
chosen as the Slave.
The timer to close and radio/single button behavior are set in the Master operator.
The following selections are set individually:
Current Sensing
Maximum Run Timer
One-Second Lock Release
Three-Second Pre-Start Warning
Right/Left-Hand Selections
SURGE PROTECTOR INSTRUCTIONS
The optional surge protector should be connected
to any inputs that have an accessory connected to
it. This includes the 3-button station, so it must be
connected to 1, 2A and 3 in all cases. The green
wire connected to ground, which is electrically the
same as terminal 4. The red wires connect to
terminals 2A and 24VDC+. This will cause the
2 amp fuse to blow if this section of the module
becomes shorted. With any of the other inputs
connected to the surge protector, if their protection
line becomes shorted due to a surge over the rating
of the module, the corresponding LED on the main
board will remain lit, causing a constant signal to
the controller. If this is found, please replace the
entire surge protector with a new unit.
Do not simply unhook the shorted wire, as this
removes the protection from the circuit that was
saved by the protector in the first place!

CHARGER BOARD SLEEP MODE
When primary AC power is not available, the operator will continue to
operate in battery only mode if the charger board is set in its RUN mode
(see Battery Backup Charger Configuration). Accessories wired into
the operator will continue to draw power, even when the operator is not
opening or closing the gate. This can dramatically reduce the amount of
standby time available from the batteries.
To extend the available standby time, the charger board has a “sleep”
mode feature which will turn off power to all controls except for any that
are wired according to the schematics below. By removing the black jumper
cap JP1 located in the upper right hand corner of the charger board this
feature can be enabled. After fifteen minutes of inactivity, all controls except those wired as shown below will turn off. Those wired as shown will
continue to have power at all times and will upon activation generate first
a “wake” signal that will power all controls back up, and then create either
an open signal or single button signal, depending on how the wire jumper
shown below is connected.

TROUBLESHOOTING
Operator fails to start:
A. If the operator has been running a large number of cycles,
the motor may have gotten hot and tripped the overload.
Allow the motor to cool down and the overload will reset
automatically.
B. Make sure you have power at the master distribution panel
and that the power has not been turned off.
C. The secondary fuse on the control board may have blown.
Replace the fuse (refer to control box parts list on page 26
[MSG-A] and page 30 [MSG-D] for part number information).
Motor operates, but gate does not move:
A. In operators with torque limiters and friction pad clutches,
check for signs of slipping. You can mark the sprocket and
clutch with a yellow or white grease pen and watch for the
lines to move apart if slipping is taking place. Adjust the
torque limiter tighter if this is the problem.
B. Check for broken chain or worn belts.
C. Check all setscrews on pulleys and sprockets and tighten
them if necessary, and check for keys which may have
fallen loose from keyways.
Motor sounds like it is working harder than normal:
A. Make sure the gate is moving freely and without binding
throughout its entire travel.
B. Check the drive chain for obstructions (if the operator has
one).
C. If the operator has an internal brake mechanism, make
sure it is releasing.
Limit switch getting out of time:
A. Check for proper tension on all limit chains to be sure there
is no jumping taking place. Mark one tooth and its corre-
sponding link and run the gate. If the marks have moved,
the chain is skipping.
B. Check the setscrews in limit cams and limit sprockets for
tightness. In rotary limit boxes, check the rotary limit nut
for sloppiness or stripped threads. Replace if necessary.
Gate stopping part way open or closed
(but no visible obstruction):
A. The control board may have received a false obstruction
input triggered by current sensing set too low. Make sure
the gate moves freely through its entire travel before adjusting the current sensing.
B. The maximum run timer may have counted down and ex-
pired. This can be caused by having the timer set too low,
if a chain or belt is broken, or if a sprocket or pulley is
slipping. When the timer expires, the gate stops and an
alarm will sound.
C. An obstruction signal from an accessory wired to the ob-
struction input may have triggered falsely. Check the control board for lit L.E.D. indicators for any of the following
inputs: safety, shadow, open obstruction, close obstruction, stop, etc. If any are lit when the operator should be
running, remove all devices hooked to that function and
hook them up one at a time and try to run the operator until
the problem device is found. Refer to page 13 for details on
the control board indicators.
Gate staying open with automatic system:
A. If there are vehicle detectors in your machine which are set
up for reverse, one of your loops or loop detectors may be
sending a false signal. Disconnect the wire harness and
try running the operator.
B. An opening or reversing device may be stuck or malfunc-
tioning. Try disconnecting these devices and hook them
back up one at a time and try running the operator until the
malfunctioning device is found.
C. Make sure the close limit switch isn’t activated. If it is, the
operator will think the gate is already closed.
HOW TO ORDER REPLACEMENT PARTS
Use the part numbers listed on the following pages. Contact your local OSCO dealer or distributor to order parts.
1. Supply the model number and serial number of your operator.
2. Specify the quantity of pieces needed and order by part number and name of part.
3. State whether to ship by freight, truck, parcel post, UPS or air express.
4. State whether transportation charges are to be prepaid or collect.
5. Specify name and address of person or company to whom parts are to be shipped.
6. Specify name and address of person or company to whom invoice is to be sent.

BATTERY MAINTENANCE
The gel-cell batteries in this operator require no routine maintenance. For assured continued performance, they should be
replaced every year.
If power is to be removed for one week or more, disconnect the negative wire from the batteries as this will prevent deep
discharging.
Fully charge before use after storage or upon initial installation.
BRUSH REPLACEMENT
Brushes should be inspected every 100,000 cycles, (200,000 for BGU-D) or
yearly, whichever comes first. The motor has two brushes, one on each side.
Original brushes are approximately 3/4” long and should be replaced when
they are 1/4” long, or sooner. If brushes are allowed to wear beyond this point,
permanent damage to the motor may result.
To inspect the brushes, remove retaining cap (A), with straight-blade screwdriver, and carefully pull assembly straight out. Measure remaining brush material (B).
To reinstall, place brush in hold, aligning rounded indentation (C), correctly
with motor shaft. Gently push in spring and align contact with oval carrier, push
in with retaining cap (D). Hold in place and thread cap into brush carrier. Do not
overtighten or cap will crack! Repeat for other brush.
B
If brushes require replacement, order kit #2510-243.

rest. Call for prompt medical attention.
EYE CONTACT: Flush eyes with large amounts of water until irritation subsides. If
irritation persists, get medical attention.
SKIN CONTACT: Flush with large amounts of water. Use soap if available. Remove
severely contaminated clothing (including shoes) and launder before reuse. If irritation
persists, seek medical attention.
INGESTION: If swallowed, DO NOT induce vomiting. Keep at rest. Get prompt
medical attention.
6. PREVENTIVE AND CORRECTIVE MEASURES
PERSONAL PROTECTION: The selection of personal protective equipment varies,
depending upon conditions of use. In open systems where contact is likely, wear
safety goggles, chemical-resistant overalls, and chemically impervious gloves.
Where only incidental contact is likely, wear safety glasses with side shields. No other
special precautions are necessary provided skin/eye contact is avoided. Where
concentrations in air may exceed the occupational exposure limits given in Section 4
and where engineering, work practices or other means of exposure reduction are not
adequate, approved respirators may be necessary to prevent overexposure by
inhalation.
ENGINEERING CONTROLS: The use of local exhaust ventilation is recommended to
control emissions near the source. Laboratory samples should be handled in a
fumehood. Provide mechanical ventilation of confined spaces.

PREVENTATIVE MAINTENANCE
IMPORTANT!
• Always disconnect power from operator before servicing.
• Keep clear of gate during operation.
GENERAL:
OSCO gate operators are designed for many years of trouble-free operation and, under recommended operating conditions, will
require only minimal maintenance. To ensure that your unit is ready for operation at all times--and to preclude serious damage
or failure--inspect the unit systematically. Proper adjustments and lubrication should be made as recommended.
LUBRICATION:
Bearings. For models which have pillow block style bearings with greaseable fittings, lubricate at least twice a year with a
lithium complex based, petroleum oil NLGI 2 rated grease. Oilite and precision sealed bearings do not require additional
lubrication.
Motor. Motors have sealed ball bearings and do not require further lubrication. If bearing noise develops after several years of
operation, bearings should be replaced by a motor repair company, or the motor should be replaced if necessary.
Drive Chain and Sprocket (slide gate models only). The main drive chain and sprockets should be inspected for wear,
cleaned, and wiped down with a lightly oiled rag every six months.
Swing Gate Arm (swing gate models only). Check all bolts for proper tension and tighten if necessary. Make sure the arm
folds overextends itself slightly against the overtravel stop to reduce the chance that the gate can be backdriven open. Adjust the
close limit slightly if additional travel is required. Lightly lubricate all pivot points with a light machine oil.
Barrier Gate Arm (barrier gate models only). Check all bolts for proper tension and tighten if necessary. If the arm has been
warped or damaged, replace as necessary.
ADDITIONAL SIX MONTH PREVENTATIVE MAINTENANCE:
1. For operators which utilize torque limiting clutches, check
for proper tightness. If there appears to be dust from wear
on the pads, inspect the pads and replace if necessary. If
the clutch cannot be adjusted tightly enough to move the
gate without slipping, the pads must be replaced.
2. For operators with V-belts, inspect for wear and replace
as necessary. Check for proper tension and adjust if required. Check all pulley setscrews for tightness and tighten
if necessary.
3. For operators with internal chain drives, inspect chain and
sprockets for wear and replace if necessary. Check for
proper tension and alignment, and adjust if required. Check
all hub sprocket setscrews and tighten if required.
4. Check limit switches and limit actuators (cams, limit nuts,
etc.) for wear and replace as required. In rotary limit switch
assemblies, wipe the limit shaft clean and apply a light
coating of dry lubricant.
5. For operators with magnetic brakes, check for proper adjustment. Brake disc must run free when the brake is engaged. For brake assemblies other than C-face style, the
brake should be adjusted so that the solenoid plunger throw
is between 3/8” to 1/2”. Too much throw will damage the
solenoid. If the solenoid emits a loud buzzing sound
when the motor is run, the brake must be adjusted.
6. In operators which have a disconnect handle, inspect disconnect handle for proper function and lubricate if necessary. Use a lithium based grease on all moving parts.
7. Inspect all nuts and bolts for proper tightness and tighten
as necessary.
8. Check all reversing devices for proper function. Inspect all
contact edges for wear and replace if required. Check photoeyes for proper alignment and function.
9. Check current sensing for proper adjustment when finished
with inspection and maintenance.
10. Inspect the installation area. Are all the warning signs intact and visible? If they are missing or need replaced, contact OSCO. Be sure there are no control stations mounted
within reach of the gate. Review safety literature with the
customer and advise them to remove any such stations
found.
For slide and swing gate operators, you must inspect
the gate for proper operation. The gate should move
easily without binding through its entire travel. If the
gate does bind, adjust or fix as required. Failure to
keep the gate in good working condition will have
adverse effects on the operator.
