Place a one inch high object (or
2x4 laid flat) under the garage door. Operate the door in the DOWN
direction. The door MUST reverse when it hits this obstruction.
If the door STOPS on the
obstruction, increase down travel by adjusting the down limit on the
operator.
When door reverses, remove the
2x4. Run the opener through a complete travel cycle 2-3 times to
test adjustment.
If the door will not reverse or
you don't feel confident in adjusting it yourself call a trained
door system technician to come inspect it.
Emergency Release / Door
Balance Test
Close Garage Door, hen pull down
on the red emergency release handle. The trolley will disconnect. If
you need to pull the emergency release handle when the door is open,
make sure no one is standing in the way of door travel (Weak or
broken springs could cause the door to fall rapidly or unexpectedly,
resulting in serious injury, death, or property damage).
Raise and lower the door manually
to see whether there is any binding or sticking.
Release door about halfway open to
test for balance. It should stay in any point of travel, supported
entirely by its springs.
The opener will reconnect
automatically when the door control or remote control push button is
pressed.
