Care of Your Opener
MAINTENANCE SCHEDULE
Every Month
Manually operate door. If it is unbalanced or binding,
call a trained door systems technician.
Check to be sure door opens & closes fully. Adjust
limits and/or force if necessary (See pages 28 and 29).
Repeat the safety reverse test. Make any necessary
adjustments (See Adjustment Step 3).
Every Year
Oil door rollers, bearings and hinges. The opener does
not require additional lubrication. Do not grease the
door tracks.
DISCONNECT THE TROLLEY:
The door should be fully closed
if possible. Pull down on the
emergency release handle (so
that the trolley release arm
snaps into a vertical position)
and lift the door manually.
The lockout feature prevents
the trolley from reconnecting
automatically, and the door can
be raised and lowered manually
as often as necessary.
TO RE-CONNECT THE
TROLLEY:
Pull the emergency release
handle toward the opener at
an angle so that the trolley
release arm is horizontal.
The trolley will reconnect
on the next UP or DOWN
operation, either manually
or by using the door control
or remote.
