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° 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 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.
