Once aligned, secure them into
position using two supplied
hexagonalheadange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.
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.
The SDO4 is now installed
and ready for programming.
Pleasedonotforgettoax
