! It is highly recommended that you reconsider using this type of gate operator on

any solid faced gate, without an external lock system on both the open and closed
position. Strong winds will greatly affect the efficiency of this operator on these
types of gates.

IMPORTANT NOTE

The gate must be level and operate smoothly and freely. If it does not, damage
to the operator may result and the life expectancy will be greatly reduced.

Safety Information

Safety Information

Automatic gate operators provide convenience and security to their users. However,
because these machines can produce high levels of force, it is important that all
installers and users be aware oft he potential hazards associated with improperly
installed or adjusted units.

The information on this page contains various safety precautions and warnings, some
highlighted with this symbol (see left margin). This symbol will identify conditions that
can result in serious injury or death. Take time to read and follow these precautions
and the other information provided.

NOTE

This operator is intended to be a part of a total gate operating system. It is the
responsibility of the purchaser and installer to ensure that the total system is safe
for its intended use.

Installer

BEFORE INSTALLATION

1

Check to see that this is the proper operator for this application. (See page

4).

2

Ensure that the gate has been properly installed and works freely in both
directions. Repair or service any worn or damaged gate hardware.

3

Install the gate operator on the inside of the property and/or fence line.

not

install an operator on the public side of the gate.

4

If the gate is near a residential area, or pedestrian traffic is expected near the
gate, additional safety equipment such as electric gate edges or photocell
detectors must be installed to prevent entrapment. Severe injury or death
can result from entrapment with the gate.

5

Certain types of gates can create greater hazards to pedestrians. Any gate
that has exposed, reachable pinch points or is constructed to allow arms and
legs to pass through it is a potential hazard. These hazards should be
guarded against.

6

Review the operation of the unit and become familiar with the manual
disconnect system and safety features of the unit.

7

Outdoor or easily accessed controls should be of the security type to prohibit
unauthorized use of the gate.

Do

Doc 01-20230
Rev B

DURING INSTALLATION

1

Be aware of all moving parts and avoid close proximity to any pinch
points.

2

Disconnect power at the service panel before making any high voltage
power connections.

3

Place controls far enough from the gate so that a user can see but cannot
touch the gate while operating the controls.

4

Place warning signs provided on the gate or in a high visibility area to
alert of automatic gate operation.

AFTER INSTALLATION

1

Make sure the user understands the basic function and safety features of
the system.

2

Leave this manual and the troubleshooting guide with the end user.

Step 1: Gate Stops

The gate must have a permanent gate stop at the full closed position. It is also highly
recommended that there be a gate stop at the determined full open position. These are
to prevent the piston from bottoming in the cylinder and to prolong the unit’s life.

Step 2:

Gate Brackets

Locate the positions of the front and rear mounting brackets. It is
recommended that these brackets be positioned at the midpoint between the
gate hinges.

It is very important that they be in-line with each other! The operator
must be level.

The two brackets should be welded to the
gate and the post as shown. They can be
welded directly or modified to suit your
particular application.

LARGE PILLARS OR WALLS

If the dimension from the centerline of the gate to the outer edge of the pillar or wall
is 3-3/4” or less, you can notch out part of the pillar or wall (see Example A – Figure

4) as shown.
If this dimension is larger than 3-3/4”, then it will be necessary to notch out larger

portion (see Example B – Figure 4) large enough to house the unit. The notch
should be 5” to 8” high. Contact a LiftMaster dealer if your application does not fit
these guidelines.

Hydraulic Adjustments

Locate the by-pass valve. Using the hex key supplied, re-engage the by-pass
valve by turning it clockwise as far as possible.

Turn power on at main power supply and at power disconnect switch. The
controller has a 7 second delay form power-up until a signal can be received.

With gate open, activate the unit to close. Using a flat blade screwdriver, slowly
turn the close pressure valve counter-clockwise until the gate begins to move,
then adjust it ¼ to ½ turn more. (Unit is shipped with pressure valves set at
minimum).

NOTE

Since the unit’s cycle time has yet to be adjusted, it may shut off too soon
or may run longer than desired.

Locate the open pressure valve. Activate the unit to open and adjust it in the
same manner as the close direction.

WARNING

The open & close pressure valves must be adjusted properly. They should
develop enough force to open and close the gate properly. If the gate
meets an obstruction there will be a minimum amount of force applied.
Check this by holding the gate when it is closing and opening.

For manual operation of the gate,

Step 8:

Adjustments

1

Locate the cycle timer “pot” on the control panel. This pot determines the
length of time the unit will run. Adjust it so the unit will fully open and close the
gate properly. Allow a few seconds for slippage against the gate stops.

2 Optional:

delay relay, locate the master/slave delay “pot” on the control panel. This pot
determines the close time delay between two units (i.e. the master closes first).

Adjust this “pot” to the desired delay time.

3 Optional:

determines how long the gate will stay open before it automatically closes.
Adjust this to the desired time.

System Check-Out

LiftMaster strongly recommends that at this time you check out the entire system.

1

Make sure the unit fully opens and closes the gate properly.

2

Check all controls that activate the gate to ensure they are working properly.

3

It is extremely important that all safety devices be checked and double
checked.

4

Double check the manual operation features and pressure valves of the
system.

19

NOTE:

Troubleshooting Guide.

If a problem should arise, see the Model HL410-21

AND FINALLY...

Install the gate caution on both the inside and outside of the gate where
they can be easily seen.

LiftMaster recommends that you pad-lock the controller door. Inform the
customer of this recommendation.

Make sure the unit and controller are free of grease or dirt. Clean if
necessary.

Clean up the area around the gate.
Look around for any tools or equipment that may be left.
Please leave this manual and the troubleshooting guide with the customer.
Let the customer know you’ve finished installing the unit and review all

pertinent information with them, including safety features and maintenance.

Limited One-Year Warranty

LiftMaster gate operators are warranted against deficiencies in material and workmanship for a
period of one (1) year from date of purchase, providing recommended installation and
maintenance procedures are followed. This warranty is in lieu of all other warranties expressed
or implied (some states do not allow limitations on how long an implied warranty lasts, so this
limitation may not apply to you) and shall be considered void if damage was due to improper
installation or use, connection to improper power source, or if damage was caused by fire, flood
or lightning. The manufacturer will not be responsible for any labor charges incurred in the
removal or replacement of deficient parts.

In case of failure due to deficiencies in material or workmanship during the warranty period, the
completer gate operator will be repaired or replaced at the manufacturer’s option. New factory
rebuilt replacements will be used. Replacement parts are warranted for the remaining portion of
the original warrant period. LiftMaster will pay freight on our return of repaired or replaced items
