CARE OF THE OPENER
When properly installed, your opener will perform efficiently with a minimum of maintenance. You will be required to
replace a light bulb or change a transmitter battery from time to time. A 9-Volt Alkaline battery is the most reliable, and
is available at Sears.
The opener does not require additional lubrication - HOWEVER - the door rollers, bearings and hinges should be
oiled yearly.
Most complaints of unsatisfactory opener operation can be traced to problems with the door itself. The opener is not
intended to correct problems caused by an unbalanced or binding door, broken door springs orfaulty door hardware.
When operating the door manually, a properly balanced door will stay in any point of travel while being supported
soley by its springs, if you encounter any difficulty when operating door manually, call a garage door serviceman,
