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.

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
