Safety Information
Safety Information
Vehicular gate systems provide convenience and security. Gate systems are
comprised of many component parts. The gate operator is only one component. Each
gate system is specifically designed for an individual application.
Gate operating system designers, installers and users must take into account the
possible hazards associated with each individual application. Improperly designed,
installed or maintained systems can create risks for the user as well as the bystander.
Gate systems design and installation must reduce public exposure to potential hazards.
A gate operator can create high levels of force, in its function as a component part of a
gate system. Therefore, safety features must be incorporated into every design.
Specific safety features include:
Gate Edges Enclosed Track Vertical Posts
Guards for exposed
rollers
Screen Mesh
Important instructions follow. These instructions are intended to highlight certain safety
related issues. These instructions are not intended to be comprehensive. Because
each application is unique, it is the responsibility of the purchaser, designer, installer
and end user to ensure that the total gate system is safe for its intended use.

Safety Precautions for Open-Roller Gates and Ornamental “Grill Type” Gates
OPEN-ROLLER GATES
Injuries occur when people get their or feet caught between the top or bottom of the
gate and the gate roller. This potential pinch-point should be guarded against at all
times. Enclosed style gate tracks are available for refitting of these rollers from
many fence suppliers. Also, roller guards are available for installing over the
rollers.
One ore more contact sensors shall be located at the leading edge, trailing edge,
and post-mounted both inside and outside of a vehicular horizontal slide gate.
Doc 01-20221
Rev D
Figure 3
Page 9
Safety Information
ORNAMENTAL “GRILL TYPE” GATES
Injuries occur when people put their hands and arms through openings in the grill
and the gate is operated. They cannot retract their arms and it gets caught between
the moving gate grill and the stationary fence post or fence. This potential hazard
can be averted by placing a screen mesh on the gate to prevent access through
openings anywhere the gate may travel.

Pre-Installed Check-List
Pre-Installed Check-List
1 Check the gate. It must operate freely. If necessary, lubricate or adjust gate to
operator installation. The gate should be level and plumb.
2 Overhead, tracked, or roller tracked gates may require back frame to be constructed
to allow for drive rail attachment.
3 If wiring has already been installed, check that it meets the following wiring
specifications.
Wiring Specifications
1 Knowing operator voltage and phase, select selection that corresponds.
2 The distance shown on the chart is the length of the wire measured in feet from
the operator to the power source. (do not exceed maximum distance.)
3 If your power distance is greater than the figures shown, it is recommended that
the power utility company be notified for a service feeder. Where feasible, a
higher voltage or three-phase operator should be used.
4 When wire larger than 12 gauge is used, a separate junction box will be needed
for operator power connection. (not supplied.)
5 Select control wire gauge form chart. If greater distance or
Lighter gauge wire is required, consult manufacture.
6 Wire run calculations are based on the national electrical code, article 430,
allowing 5% voltage drop.
7 Supply voltage must be within 10% of the operator rating under load conditions.
8 Connect power accordance with local codes.
9 Wire table is based on stranded copper wire. Wire insulation must be suitable to
application.

Step 1:
See Figure 5.
Concrete Pad
1 Layout concrete pad as detailed.
2 Locate conduit, as required, prior to pouring concrete.
3 Pour concrete, insuring that pad is level and above the ground line. Pad must
be a minimum of 24 inches in depth or below the frost line, whichever is
greater.
4 Allow concrete to set at least 2 days before installing unit.
5 Locate four (4) ½” threaded anchors (not supplied) or other means of fastening
as shown. Anchors must be positioned accurately and be secure in the
concrete.
NOTES
Always use separate conduits for power wiring and control wiring.
You may want to install extra conduit for future wiring
considerations.
For detailed information on the emergency disconnect system, see
instructions supplied with it.
This in only a suggested layout, other pad layouts are possible.

Step 2:
Drive Rail
IMPORTANT NOTES
It is very important that the drive rail be:
Level and parallel to the gate and operator.
As close as possible to the 11 ½” dimension.
Very securely mounted to the gate and back frame.
1 If using your own drive rail, see detail of LiftMaster drive rail for proper
dimensions.
2 The length of the drive rail should be the gate opening width plus
2-3 feet.
3 It is suggested that the drive rail be made out of or coated with a
material that will inhibit rust.
4 If you are using the LiftMaster anti-skid tape or another means of anti-
skid, install it to the rail now.

Step 3:
Mounting
1 Remove the cover from the operator.
2 Carefully secure the operator to the concrete pad with the drive wheel facing the
gate.
IMPORTANT NOTE
Operator must be level and parallel with the gate and drive rail. By loosening
the bolts securing the mounting legs to the unit, the operator can be slightly
adjusted up or down. Retighten bolts.
Make sure that the drive rail and wheels are aligned properly. See detail
below. Also see page 15.
Step 4:
Vent Cap
Remove the threaded plug from the pump tank and install the vent cap in its place. Do
not throw plug away. Leave it with unit.

Step 5:
See Figure 8.
Limit Shoes
1 Manually open the gate to the full position.
2 Locate the open limit switch lever and mark its position.
3 Manually close the gate to the full close position.
4 Locate the close limit switch lever and mark its position on the drive rail.
5 Manually open the gate about halfway. Per drawings below, measure and
drill holes. Mount both limit shoes to underside of drive rail.
IMPORTANT NOTES
The limit shoes are slotted, so minor adjustments may be made later
for the fine tuning of the full open and close position. Also, note that
the limit switches themselves may be slightly adjusted up or down.
It is highly suggested that gate stops be installed to the gate at the full
open and closed positions.
Due to the fact that this unit has no brake, there will be some gate
coasting and, depending on gate weight, it could be considerable, so it
might drift past the limits.
If coasting is a problem and a precise stop is needed, part number 410.1726
(supplied) should be installed. See directions.

Step 6:
See Figure 10.
The suspension system is semi-factory set; simply loosen the suspension separate or
bolt completely. This will allow both wheels to pinch the drive rail.
If more or less pressure is required, adjust both upper and lower suspension spring lock
nuts as desired.
Suspension System
NOTE
It is suggested that the separator bolt be removed and left with unit. If it is not
removed, make sure that it can not interfere with suspension system.
IMPORTANT NOTES
Both springs should apply about the same amount of pressure.
If using the LiftMaster drive rail, make sure that the drive rail guide wheel is
positioned properly. See Figure 9.
It is very important that the suspension system is adjusted properly. This
system puts pressure on the drive wheels so they can pinch together on the
drive rail. This system also allows the drive wheels to “float” so they can follow
any slight misalignment of the drive rail. If the springs are overtightened, it will
reduce their life span. But on the other hand, if they are under-tightened, the
drive wheels may slip on the drive rail.

Step 7:
The pump is equipped with a manual bypass valve. By positioning the valve handle
down (manual operation), the gate can be back-driven open or closed.
A back-up to this is the suspension separator bolt. By tightening this bolt, the drive
wheels will be pushed off the drive rail.
Manual Operation
NOTE
When manually opening or closing the gate, it is not I the beginning, easy to get
the gate started. Since fluid has accumulated in the drive motors, it will take a
good size push to get the gate started.

Single phase to L1, L2 and GROUND. Three phase to L1, L2, L3 and
GROUND.
2 Connect all controls to the control wiring terminal strip. Reference the electrical
diagram supplied with the unit.
IMPORTANT NOTE
On three-phase units, when unit is first run, if you can hear the pump running
but the gate does not move:
1 Make sure the manual bypass valve is in the automatic operation
position. See page 21.
