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.

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
/

”) drill bit.
d. Fit M10 x 32mm screws and washers (not supplied) to each of the four (4)

make sure that it does not alter the curtain’s normal lead in to the guide.

40Nm) to the bracket.

a safe and suitable lifter.
WARNING! Make sure the door is secure in the support,
is stable and will not move.
d. At the end where the opener will be fitted, use pen to mark the
position of the saddle on the door bracket and the position of the
door bracket on the wall to assist in reassembling.
e. Remove the bolts and saddle from the door bracket.
