Once aligned, secure the towing
arms into position using the 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.
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 41.
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.
