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.
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.
