Chamberlain 7902 Garage Door Opener User Manual


 
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 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.
