Care & Maintenance Of Your Opener - Sears 39.18205SR - 1/2 HP Owner's Manual

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.
THE OPENER IS NOT INTENDED TO CORRECT
ANY PROBLEMS THAT ARE CAUSED BY AN
UNBALANCED OR BINDING DOOR, BROKEN
DOOR SPRINGS
HARDWARE.
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.
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.
THE SAFETY REVERSE SYSTEM IS IMPORTANT
(SEE Pg. 22). GARAGE DOOR MUST REVERSE ON
CONTACT WITH A 1-INCH OBSTACLE PLACED ON
THE FLOOR. FAILURE TO PROPERLY ADJUST
OPENER MAY RESULT IN SERIOUS PERSONAL
INJURY FROM A CLOSING GARAGE DOOR.

MAINTENANCE OF YOUR OPENER
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 emergency handle. If the chain
returns to the position described and illustrated in Step 4
page 9, DO NOT make ANY further adjustments.
TRANSMITTER: The 3-function transmitter will operate
more than one garage door opener, if desired. The push
buttons may also be used to operate other 18000SR
Series garage door openers and light products, Models
DOOR 18727 and 18725. The standard transmitter may be
secured to car sun visor with clip provided. Additional
transmitters can be purchased at any time. Refer to
Accessories on page 5.
Any new transmitter must be set to the same code as
the original transmitter. Page 23 explains how to change
your existing code and use the transmitter(s) with the
other receivers mentioned above. Self service of your
radio controls is not recommended. If service is needed,
contact your nearest Sears Service Center.
TRANSMITTER 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
or other control will operate). If light does not come on,
replace the battery. If transmission range lessens, check
the battery test light.
TO CHANGE
compartment cover back. Remove old battery and
position and new 12 Volt battery as directed.
