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 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.
