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.
