Care Of The Opener; Maintenance Of Your Opener - Merik 501M El Manual Del Propietario

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 OR BY FAULTY DOOR
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 page 22). GARAGE DOOR MUST REVERSE
ON CONTACT WITH A 25mm 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 manual release handle. If the
chain returns to the position described and illustrated
in Step 4 page 9, DO NOT make ANY further
adjustments.
REMOTE CONTROL TRANSMITTER: The portable
remote control may be secured to a car sun visor with
the clip provided. Additional remote transmitters can
be purchased at any time for use in all vehicles using
the garage. Refer to Accessories on page 5.
Any new remotes must be set to the same code as
the original remote. Code setting procedures are
described on page 23.
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 will operate). If light 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. Remove old battery and
position the new 12 Volt battery as directed.
