CENTURION SYSTEMS SDO4 SMART Installation Manual page 41

SECTION 6
The two towing arms must
be joined in such a way
that they are just short of
parallel to the garage door
and the ceiling.
Angle 'Z' should be ±80°
when the garage door
is in the closed position,
as shown in Figure 73.
This will put less strain
on the motor on start-up
and, furthermore, aid in
preventing the garage door
from being forced open by
hand.
Once aligned, secure them into
position using two supplied
hexagonal head flange nuts and
bolts: one set through the bottom
hole of the straight towing arm,
and the other through the top hole
of the bent towing arm.
Please do not forget to affix
the safety sticker and tag.
The SDO4 SMART is now
installed and ready for
programming.
