OPERATION OF YOUR OPENER

Your opener can be activated by any of the following devices:

The Lighted Door Control Button. Hold the button down until door starts to move.

The Outside Keylock or Keyless Entry System (if you have installed either of these accessories).

The Remote Control Transmitter. Hold the push button down until the door starts to move.

Opening the Door Manually:

Door should be fully closed if possible. Weak or broken springs could allow an open door to fall rapidly. Property damage or serious personal injury could result.

The door can be opened manually by pulling the release handle straight down (so that the trolley release arm snaps into a vertical position). To reconnect the door, pull the release handle toward the opener at a 45˚ angle so that the trolley release arm is horizontal. See illustration 14.

Do not use the manual release handle to pull the door open or closed.

When the Opener is Activated by Remote Control or Lighted Door Control Button:

1.If open, the door will close. If closed, the door will open.

2.If closing, the door will reverse.

3.If opening, the door will stop (allowing space for entry and exit of pets and for fresh air).

4.If the door has been stopped in a partially open position, it will close.

5.If an obstruction is encountered while closing, the door will reverse.

6.If an obstruction is encountered while opening, the door will stop.

7.The optional Protector System™ uses an invisible beam which, when broken by an obstruction, causes a closing door to open and prevents an open door from closing. It is STRONGLY RECOMMENDED for homeowners with young children.

Allow a 15 minute cooling period after 5 continuous operations of the opener.

The opener light will turn on: 1. when opener is initially plugged in; 2. when the power is interrupted; 3. when the opener is activated.

The light turns off automatically after 4-1/2 minutes. Bulb size is 40 Watts maximum (230V, E27).

CARE OF YOUR OPENER

When properly installed, opener will provide high performance with a minimum of maintenance. The opener does not require additional lubrication.

Limit and Force Adjustments: These adjustments must be checked and properly set when opener is installed. Only a screwdriver is

required. Weather conditions may cause some minor changes in the door operation, requiring some re-adjustments, particularly during the first year of operation.

Refer to the limit and force adjustments on page 4. Follow the instructions carefully and repeat the safety reverse test after any adjustment.

Remote Control Transmitter: The portable remote control may be secured to a car sun visor with the clip provided. Additional remotes can be purchased at any time for use in all vehicles using garage. Refer to Accessories. The receiver must be programmed to operate with any new remote.

Remote Control Battery: The lithium batteries should produce power for up to 5 years. When the light becomes dim or does not come on, replace the battery. If transmission range lessens, check the battery test light.

To Change Battery: To replace batteries, use the visor clip or screwdriver blade to pry open the case. Insert batteries positive side up. To replace cover, snap shut along both sides. Do not dispose of the old battery with household waste. Take battery to a proper disposal center.

MAINTENANCE OF YOUR OPENER

Once a Month:

Repeat safety reverse test. Make any necessary adjustments.

Manually operate door. If it is unbalanced or binding, call for professional garage door service.

Check to be sure door opens and closes fully. Adjust Limits and/or Force if necessary.

Once a Year:

Oil door rollers, bearings and hinges. The opener does not require additional lubrication. Do not grease the door tracks.

HAVING A PROBLEM?

1. Opener doesn't operate from either door control or remote:

Does the opener have electric power? Plug lamp into outlet. If it doesn't light, check the fuse box or the circuit breaker. (Some outlets are controlled by a wall switch.)

Have you disengaged all door locks? Review installation instruction warnings on page 1.

Is there a build-up of ice or snow under door? The door may be frozen to ground. Remove any obstruction.

The garage door spring may be broken. Have it replaced.

Repeated operation may have tripped the overload protector in the motor. Wait 15 minutes. Try again.

2. Opener operates from remote but not from door control:

Is door control button lit? If not, remove the bell wire from the opener terminals. Short the red and white terminals by touching both terminals at the same time with a piece of wire. If the opener runs, check for a faulty wire connection at the door control, a short under the staples, or a broken wire.

Are wiring connections correct? Review page 3.

3. Door operates from door control but not from remote:

Check the battery test light. Replace battery if necessary.

If you have two or more remotes and only one operates, review receiver programming procedures on page 4.

Is the door control button flashing? The opener receiver must re-learn the remote control code. Follow the instructions on page 4.

4. Remote has short range:

Is battery installed? Check battery test light. If the light is dim, change the battery.

Change the location of the remote control on the car.

A metal garage door, foil-backed insulation or metal siding will reduce the transmission range.

Make sure antenna is fully extended across ceiling towards the door.

5. Door reverses for no apparent reason and opener lights don't blink:

Is something obstructing the door? Pull manual release handle. Operate door manually. If it is unbalanced or binding, call for professional garage door service.

Clear any ice or snow from garage floor area where garage door closes.

Review Force Adjustment.

If door reverses in FULLY CLOSED position, decrease travel limits.

Repeat safety reverse test after adjustment is complete.

The need for occasional adjustment of the force and limit settings is normal. Weather conditions in particular can affect door travel.

6.Door reverses for no apparent reason and opener lights blink for

5 seconds after reversing:

Check The Protector System™ (if you have installed this accessory). If the light is blinking, correct alignment.
