Care of Your Opener

MAINTENANCE SCHEDULE

Once a Month
• Manually operate door. If it is unbalanced or binding,
call a trained door systems technician.
• Check to be sure door opens and closes fully. Adjust
limits and/or force if necessary (see pages 27 and 28).
• Repeat the safety reverse test. Make any necessary
adjustments (See Adjustment Step 3).
Once a Year
• Oil door rollers, bearings and hinges. The opener does
not require additional lubrication. Do not grease the
door tracks.

To Open the Door Manually

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 control
console or remote.
