To Open the Door Manually

DISCONNECT 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
a 45° degree 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.

TO RECONNECT

• To prevent possible SERIOUS INJURY or DEATH from

a falling garage door:

– If possible, use emergency release handle to

disengage trolley ONLY when garage door is
CLOSED. Weak or broken springs or unbalanced
door could result in an open door falling rapidly
and/or unexpectedly.

– NEVER use emergency release handle unless garage

doorway is clear of persons and obstructions.

• NEVER use handle to pull door open or closed. If rope

knot becomes untied, you could fall.

Using the Wall-Mounted
Door Control

Press the push button to open or close the
door. Press again to reverse the door during
the closing cycle or to stop the door while it's
opening.
