GATE OPERATOR
CLASSIFICATIONS
All gate operators can be divided into one of four different
classifi cations, depending on their design and usage.
Class I: Residential
A vehicle gate operator (or system) intended for use in a
home of one to four single-family dwellings, or a garage or
parking area associated therewith.
Class II: Commercial or General Public Access
A vehicular gate operator (or system) intended for use in
a commercial location or building such as a multi-family
housing unit (fi ve or more single-family units), hotel, garage,
retail store, or other building servicing the general public.
Class III: Industrial or Limited Access
A vehicular gate operator (or system) intended for use in
an industrial location or building such as a factory or loading dock area or other locations not intended to service
the general public.
Class IV: Restricted Access
A vehicular gate operator (or system) 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.
SAFETY INFORMATION
AND WARNINGS
Read the following before beginning to install LINEAR slide
gate operators:
1. Read the yellow “Safety Instructions” brochure enclosed
with the packet of information. If you do not have one,
please call LINEAR 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. 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. You must install all required safety equipment.
PRE-INSTALLATION INFORMATION
Before unpacking, inspect the carton for exterior damage. If
you fi nd damage, advise the delivery carrier of a potential
claim.
IMPORTANT!!
Before installing the gate operator, make sure the gate’s slide
is 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 be designed so that airfl ow through the fabric
is ample to prevent wind resistance and drag.
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 LINEAR slide 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. 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. You must use Belden 8760 Twisted Pair Shielded Cable
(or equivalent) only – LINEAR part number 2500-1982, per foot). See
page 9 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.

HSLG OPERATOR INSTALLATION GUIDE
POST MOUNTING INSTRUCTIONS FOR MODEL HSLG
Before installing, make sure the gate rolls or slides freely,
and that all exposed rollers are properly covered. The gate
must be covered with fabric with openings no larger than
2 1/4” in size, to a minimum height of 48 inches from ground
level. On picket-style gates, if pickets are spaced less than
2 1/4” apart, mesh is optional.
Use two 3 - 3 1/2” OD galvanized posts and secure with
concrete footings as shown, length to be determined by local codes, frost line depth and soil conditions. Secure the
operator to the posts using the 4” U-bolts, side plates,
and hardware. There are a total of eight side plates. There
are six 3/16” side plates which should be mounted on the
outside top and bottom of the cabinet, two 3/16” side plates which
go on the top inside and two 1/2” side plates which should be
mounted on the inside top of the cabinet as shown in the illustration at the right.
To assemble the drive chain and gate brackets, refer to page 6.
Make sure that the chain sag does not exceed recommended
sizes and that the chain does not come into contact with the
moving parts of the gate or ground.
For optional pad mounting instructions, see LINEAR drawing
#2700-360.
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 pedes-
trian 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.

HSLG OPERATOR INSTALLATION GUIDE
GATE BRACKET AND CHAIN ASSEMBLY INSTRUCTIONS
Numbered items in these
drawings are for instructional reference only. For
actual part numbers, go to
the parts lists in the back of
this booklet.
Assemble a gate bracket (1) to the front edge of the gate,
using two U-bolts (2), and mounting hardware (3). Before
tightening down completely, be sure the bracket is parallel to the gate. Tighten the U-bolt hardware the rest of the
way, then screw the square head bolts (4) into the threaded
holes in the gate plate until they bottom out against the
gate. These will help keep the bracket from twisting on
the pipe.
Slide a threaded chain pin (5) through the bracket as shown,
with spring (6), fl at washer (10), and two hex nuts (7).
Attach one end of the drive chain (8) to the chain pin using
master link (9) and begin unrolling it toward the operator.
Remove the rain cover from the back of the slide gate operator. Carefully thread the drive chain under the fi rst idler,
over the drive sprocket, and then under the last idler. Make
sure you feed most of the chain through the sprockets for
attaching to the back end of the gate.
Assemble the other gate bracket on the rear edge of the
gate, using the same process as you did with the front gate
bracket. Once this is done, take the other chain pin, spring
and jam nuts and assemble with the end of drive chain and
the other master link.
At this point you should be able to adjust the chain tension
by tightening the jam nuts on each end. Approximately 1/4”
to 3/8” of slack per foot of drive chain is acceptable. Make
sure the chain does not drag on the ground, across the
gate rollers or the idler frame of the operator.
Additional mounting holes have been provided in the gate
bracket for installer convenience.

TORQUE LIMITER ADJUSTMENTS
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 and must be adjusted
during installation. Adjust the torque limiter tight enough to keep it from slipping during normal
operation.
To adjust the torque limiter in model HSLG:
1. Loosen the jam nut.
2. To increase the output, turn the adjustment nut clockwise one fl at, or 1/6 turn, at a time
until desired output is obtained.
To reduce the output, turn the adjustment nut counterclockwise one fl at, or 1/6 turn, at a
time until desired output is obtained.
3. Tighten the jam nut against the adjustment nut when fi nished.

HSLG 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 LINEAR 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 specifi cations 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 automatically reset after the motor
cools down.
LIMIT NUT ADJUSTMENTS
The limit nuts are not preset at the factory and must be adjusted for the length of the gate the operator is installed on. The
limit switches are activated by two threaded nylon rotary limit nuts which are attached to a threaded shaft and driven by chain
and sprockets from the main drive shaft. Remove the cardboard fi ller before attempting to adjust the limit nuts.
With the gate connected to the gate operator in a mid-travel position, and the power disconnect switch turned OFF, disconnect the operator by using the manual disconnect lever. Instructions for the manual disconnect can be found in the individual
operator owner’s guides. Once the operator has been disconnected, manually move the gate by hand to within a foot of its
fully open position (the foot of distance is necessary to allow for coasting of the operator after the limit switch is tripped).
Once the gate is in this position, adjust the open limit nut until it activates the limit switch for open, LSO-1. Press down on
the detent plate and rotate the nut along the threaded shaft. Refer to the illustration below for additional details.
Once the open limit nut is set, repeat the above process for the close direction nut and the LSC-1 limit switch.
After fi nishing the initial limit nut adjustments, reposition the gate to approximately its center of travel. Re-engage the operator
and turn the power disconnect ON. Stand clear of any moving parts and press the OPEN button on the three-button station.
If the gate begins to close instead of open, press the STOP button immediately. Find the dip switch block on the main control
board and switch the hand of operation (dip switch #4, see page 9) and try to open the gate again. Observe the gate as it
runs through a complete cycle in both directions, and adjust your limits again if necessary. Fine levels of adjustment can also
be achieved by adjusting a few teeth on the nut at a time. If the gate stops in mid travel, the open or close current sensor
adjustment or the maximum run timer may need adjustment (see page 11).

DIAGNOSTIC
L.E.D.s
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 fi rst. 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 multi turn 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 multi turn 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 confi gure 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 fl ashing 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, the reverse delay is three seconds. In DC operators only, this also disables the inherent DC brake
(provided the R2 brake resistor is cut, see picture above). In the OFF position, the reverse delay is 1 1/2 seconds and
the DC inherent brake is enabled.
#7 Not used at this time.
#8 This switch is used to set Master/Slave confi guration. Operators which are stand-alone or master units should be set
to OFF, while only slave units should have this switch set to ON.

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 traffi c is passing through.
Depending on dip switch #2, these devices will either begin three seconds before
the operator starts, or only while the motor is running. (See page 9 for details.)
Controls intended for user activation must be located at least six feet (6’) away from any moving part of the
gate and where the user is prevented from reaching over, under, around or through the gate to operate the
controls. Outdoor or easily accessible controls shall have a security feature to prevent unauthorized use.
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 purpose of this function!

HSLG 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
LINEAR control board has separate Multi-turn potentiometers for adjusting in both directions independently. The adjustment
should be set light enough to maintain minimal force (50-75 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 9 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 9) 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. Additional fi ne adjustment by 1/4 turns may be
necessary to eliminate false triggering.
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 confi gured
for the time it takes to run the gate fully open or closed, plus an additional 15 seconds. See page 9 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 9 for details. Do not use the auto close timer without an appropriate reversing
device installed!
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 – LINEAR part number 2500-1982, per foot). See page 9 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.

ONBOARD L.E.D. INDICATOR DESCRIPTIONS
Control Board L.E.D. Indicators:
OPEN This indicator is lit when an open signal is present. This signal can come from such devices as button
stations, radio receivers, keypads and telephone entry systems.
CLOSE This indicator is lit when a closed signal is present. This signal typically comes from three-button sta-
tions.
STOP This indicator is lit when there is a break in the stop circuit. Make sure there is a stop button wired in
andworking properly.
SINGLE This indicator is lit when a signal from a single-button station or radio receiver is present.
CLOSE OBST This indicator is lit when a close obstruction signal is present. This signal can come from edges and
photo eyes which have been wired to the close obstruction inputs.
OPEN OBST This indicator is lit when an open obstruction signal is present. This signal can come from edges and
photo eyes which have been wired to the open obstruction inputs.
SAFETY LOOP This indicator is lit when a reversing signal is present. This signal is generated by a loop detector wired
to the safety loop terminals.

HSLG OPERATOR INSTALLATION GUIDE
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 fi rst place!

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 pages
27 [single phase] or 28 [three phase] 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 tight-
en 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
corresponding 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.
C. Check the chain tension along the output sprocket and
idlers. Mark the chain and one tooth of the sprocket as
described above and run the gate. Check for jumping.
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
expired. 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
obstruction 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 12 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 LINEAR 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.

PREVENTATIVE MAINTENANCE
IMPORTANT!
• Always disconnect power from operator before servicing.
• Keep clear of gate during operation.
GENERAL:
LINEAR 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 fi ttings, 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 over travel stop to reduce the chance that the gate can be back driven 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
photo-eyes for proper alignment and function.
9. Check current sensing for proper adjustment when fi nished
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
LINEAR. 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 fi x as required. Failure to
keep the gate in good working condition will have
adverse effects on the operator.
