CARE OF THE OPENER
When properly installed, opener will provide high
performance with a minimum of maintenance. The opener
does not require additional lubrication.
Most complaints of unsatisfactory opener operation can
be traced to problems with the door itself. When operated
manually, a properly balanced door will stay in any point
of travel while being supported entirely by its springs.
CHAIN TENSION ADJUSTMENT: After installation of the
opener and adjustment of forces and limits, the chain may
appear loose. This is normal.
TO CHECK THE CHAIN TENSION: Disconnect the trolley
by pulling the red handle. If the chain returns to the
position described and illustrated in Step 3 page 9, DO
NOT make ANY further adjustments.
THE OPENER IS NOT INTENDED TO CORRECT ANY
PROBLEMS THAT ARE CAUSED BY AN UNBALANCED
OR BINDING DOOR, BROKEN DOOR SPRINGS OR BY
FAULTY DOOR HARDWARE.
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 on page 4.
Any new remotes must be set to the same code as the
original remote. Code setting procedures are described on
page 23.
LIMIT AND FORCE ADJUSTMENTS: These adjustments
must be checked and properly set when opener is installed.
Only a screwdriver is required. Pages 20 and 21 refer to the
limit and force adjustments. Follow the instructions carefully. REMOTE CONTROL BATTERY: The 12 Volt battery
should produce power for at least one year. As long as
there is adequate power, the transmitter battery test light
will glow when the push button is pressed (and the opener
will operate). 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: Slide the battery compartment
cover back. Discard the old battery and Position the new
battery as indicated on the case.
REPEAT THE SAFETY REVERSE TEST AFTER ANY
ADJUSTMENT. Weather conditions may cause some
minor changes in the door operation, requiring some
readjustments, particularly during the first year of
operation.
