7. Pinning the Door
Pinning the Door to the drum:
Pinning the door’s curtain to its drum maintains security when the opener is
closed. If the curtain is not pinned the door can be partially opened manually.
a. Fully close the door.
b. Mark a minimum of two (2) drill holes on the drum to each end of the door.
c. Drill holes using 3.2mm (
1
/
8
”) drill bit.
d. Fit M10 x 32mm screws and washers (not supplied) to each of the four (4)
holes. This screw should be positioned as low as possible in the grove, but
make sure that it does not alter the curtain’s normal lead in to the guide.

8. Proping the Door
Prepare the Door:
a. At the end opposite to where the opener will be fitted, check that the U-bolt
which holds the door axle to the bracket is tightened securely.
b. Open the door completely and tie rope around the door roll. Do not tie the
rope too tight as damage to the curtain may ensue. This will stop the door
unrolling when taken off the bracket
c. At the end where the opener is to be fitted, support the door with a door stand
or suitable prop. Place a towel between the door and the prop to protect the
door from damage.
d. At the end where the opener will be fitted use a pencil to mark the position of
the U-bolt in the door bracket and the position of the door bracket on the wall
to assist in reassembling.
WARNING! The U-bolt must be done up tightly to ensure
the stored energy in the springs cannot be unexpectedly
released.
WARNING!
Make sure the prop is
snug under the door and is stable.
