> SCREW MOUNTINg YOUR MOTOR TO A CONCRETE POST.
This type of installation is recommended in regions with a high rate of snow fall, or in areas at risk of
fl ooding. The principal is the same as below, but in this case the motor is raised above ground level. The
height of the concrete post is up to you. Remember that in all cases the height of the rack is directly
linked to the fi nal height of the motor.
ASSEMBLINg THE RACKS.
The supplied racks are made from a thermoplastic
material with a steel insert; they are suitable for
gates with a maximum weight of 500kg.
They are easily mounted to the gates with screws.
Self tapping screws are provided.
If the design of your gates will not permit the
racks to be mounted directly upon them then
mounting pads will have to be made. (Figure 1)
The height of the racks should be adjusted in a
way which prevents the weight of the gates from
resting on the motor's pinion. There should always
be a gap of between 1.5 and 2mm between
the pinion and the rack. This should remain the
case throughout the course of the gate's travel.
Any gap beyond these tolerances will provoke
premature wear not covered by the product's
guarantee.
It is imperative to never grease the
racks.
- Place the rack on the motor pinion and mark
a
fully the emplacements of the fi xing holes.
The rack should be perfectly horizontal. Also
trace a line marking the upper edge of the rack.
Continue in this way along the length of the gate.

NB: Use a section of rack to support two consecutive
sections during this procedure. (Figure 3)
