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 to adjust the limits. 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 2. Follow the instructions
carefully and repeat the safety reverse test after any
adjustment.
Remote Control Transmitter: 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. If transmission range
decreases, replace battery.
To Change Battery: 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.

TROUBLE SHOOTING
1. Opener doesn’t operate from 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
warning on page 1.
• Try a new battery.
• If you have two or more remotes and only one operates, review
receiver programming procedures in Step 21.
• 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 professionally
replaced.
2. Remote has short range:
• Is battery installed? Try a new one.
• Change the location of the remote control in the car.
• The metal garage door, foil-backed insulation or metal siding will
reduce the transmission range.
3. Door reverses for no apparent reason and opener lights don’t
blink:
• Is something obstruction the door? Pull Manual Release Handle.
Operate door manually. If it is unbalance or binding, call for profes-
sional garage door service.
• Reprogram the Force.
• Clear any ice or snow from garage floor area where garage door
closes.

Repeat safety reverse test after adjustment is complete.
The need for occasional adjustment of the Limit positions is normal.
Weather conditions in particular can affect door travel.
