4. Motor assembly mounting
Unscrew the 4 perimeter nuts of the motor assembly
q
, by using a 10mm socket wrench, leaving inserted
the respective bolts
w
and separating it from the
tightening plate
e
(fig. 6).
Rest the plate on the point chosen for the installation,
checking its correct positioning relating to the vehicle’s
driving direction again, and mark the perimeter of
the mounting plate, the central hole position and the
position of the perimeter screws.
If you prefer to let the control cable pass through the
passing hole, make a ∅18 mm hole corresponding to
the central hole of the plate.
Sandpaper and thoroughly clean both the roof, in the
area chosen for the installation, and the lower part of
the tightening plate to eliminate any trace of grease or
dust. For cleaning the mounting plate and the roof, use
the special cleaner suggested by the manufacturer of
the adhesive.
After the cleaner has dried, apply an uniform layer of
epoxy or polyurethane structural adhesive (e.g. Loctite
A&B, Loctite Terostat NS939, 3M DP105, 3M DP125,
Sicaflex 292) to the lower part of the tightening plate,
at room temperature, following the instructions.
Put, in the previously cleaned area (paying attention
to the vehicle driving direction), the plate on the roof
by pressing it firmly in order to guarantee both correct
distribution of the adhesive on all the surface and
maximum adhesion.

If necessary screw in the 6 additional perimetral
tightening screws
q
(provided). Take care that
the 4 perimetral bolts
w
are available, as they are
necessary to tighten the motor assembly. The choice
of screw type must be done based on the thickness
and the kind of material which the vehicle roof is made
of (fig. 7).
Stretch a mastic cord all around the edge of the
tightening plate, and around the 6 perimetral screws,
to guarantee that the installation is fixed (fig. 8).
Observe the drying time necessary for the adhesive
(as indicated by the manufacturer).
Install the motor assembly on the tightening plate by
passing the control cable from the desired position
(see step 3. Choosing the route for the control cable).
Inside the motor assembly do not attach the cable
to the vehicle roof with straps or cable seals. The
cable must be free to move during the rotation of the
antenna.
