Align the holes on the side of the
tensioning bracket with the holes of
the header bracket.
Position the SDO4 in place, with
the open end of the drive rail facing
the floor, and the tensioning bracket
towards the garage door. You will
need a second person to assist you
with this.
6.2.2.2. Mounting the SDO4 to
the header bracket
If you are on your own,
use a ladder to support
the control unit end of
the SDO4 while you are
positioning it for the next
step (Figure 52).
If, after securing the header
bracket, it is slightly out
(not level), use a hammer
to knock the tabs gently up
or down with a small spirit
level placed on top of them.
This will ensure a perfectly
level installation.

It is important at this point
of the installation to ensure
that the batteries are
connected before continuing
with the installation.
