HAVING A PROBLEM? (CONT.)

12. Opener strains:

Door may be unbalanced or springs are broken. Close door and use manual release rope and handle to disconnect trolley. Open and close door manually. A properly balanced door will stay in any point of travel while being supported entirely by its springs. If it does not, call for professional garage door service to correct the problem.

13. Opener motor hums briefly, then won't work:

Garage door springs are broken. SEE ABOVE.

If problem occurs on first operation of opener, door is locked. Disable door lock.

Repeat safety reverse test after adjustment is complete.

14. Opener won't activate due to power failure:

Pull manual release rope and handle down to disconnect trolley. Door can be opened and closed manually. When the power is restored, pull the manual release handle straight back. The next time the opener is activated, the trolley will reconnect.

The Outside Quick Release accessory (if fitted) disconnects the trolley from outside the garage in case of power failure.

15. Setting the limits manually:

1.Press and hold the black button until the yellow indicator light starts flashing slowly then release.

2.Push and hold the black button until the door reaches the desired UP (open) position. Adjust the position of the door by using the black and orange buttons. Black moves the door UP (open) and orange moves the door DOWN (close).

Check to be sure the door opens high enough for your vehicle.

3.Push the remote control or door control. This sets the UP (open) limit and begins closing the door. Immediately press either the orange or the black button. The door will stop.

Adjust the desired DOWN (close) limit position using the black and orange buttons. Check to be sure the door is fully closed without applying excessive pressure on the rail (rail should not bow upwards and the chain/belt should not sag or droop below the rail). Push the remote control or door control. This sets the DOWN (close) limit and begins opening the door.

NOTE: If neither the black or the orange button is pressed before the door reaches the floor, the GDO will attempt an Automated Limit Setting, reversing the door off the floor and stopping at the set Up limit. If the worklight does not blink 10 times, limits setting has been successful and doesn't need to be manually done; the DOWN limit will be set to the floor.

Regardless of setting the limits automatically or manually, the force MUST be learned in order to properly complete the setting of limits. Refer to section 26, Setting the Force.

4.Open and close the door with the remote control or door control 2 or 3 times.

If the door does not stop in the desired UP (open) position or reverses before the door stops at the DOWN (close) position, repeat Setting the Limits manually one more time.

If the door stops in both the desired UP (open) and DOWN (close) positions, proceed to Test the Safety Reversal System.

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 Settings: These settings must be checked and properly set when opener is installed. Weather conditions may cause some minor changes in the door operation, requiring some re-adjustments, particularly during the first year of operation.

Refer to Setting the Limits and Force on page 5. Follow the instructions carefully and repeat the safety reverse test after any adjustment.

Remote Control: The 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. Any new remotes must be programmed into the opener.

Remote Control Battery: The lithium batteries should produce power for up to 5 years. If transmission range lessens, replace battery.

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 batteries to a proper disposal center.
