Follow instructions which apply to your door
type as illustrated.
TO PREVENT DAMAGE TO ALL LIGHT-
WEIGHT DOORS AND DOORS WITH
WINDOWS, DO NOT REST THE OPENER
ON THE DOOR.
SECTIONAL DOOR & 1-PIECE DOOR
WITH TRACK
NOTE: A 25mm board is convenient for setting
an ideal door-to-T-rail distance. It is not necessary
when headroom is insufficient.
PROCEDURE: Raise the opener onto a stepladder.
Open garage door. Place a 25mm board on the top
section of door near centerline as shown. Rest T-rail
on board as shown.
1-PIECE DOOR
WITHOUT TRACK
PROCEDURE: Measure the distance from floor to
top of door (in fully open position and parallel to the
floor). Using a stepladder as a support, raise opener
to the same distance from the floor (it will have a
slight angle as shown).
The top of the door should be level with the top of
opener. For maximum efficiency, do not position
opener more than 5cm above this point.

springs, it may be necessary to lift opener onto
a temporary support.
CAUTION: The opener must either be secured to a
support or held firmly in place by another person.
Raise T-rail until pulley and header brackets come
together. Align bracket holes and join with clevis pin
as shown. Insert ring fastener to secure.
If the top panel hits the trolley when you raise
the door, pull down on the trolley release arm to
disconnect the inner and outer sections. The
trolley can remain disconnected until Step 11 is
