Mayline Security Shade - Manual (Page 7)

If after adjusting the Security Shade the door
still does not pull down properly, damage to the
Spring Hubs may have occured during
shipment. The following are steps to correct
this issue in the field.
1. Remove (6) screws from housing top and lift
top off. (Fig. 1A)
2. Observe how door is installed in housing, it
will have to be re-installed in the same manner.
While holding the door firmly, remove the slam
rail. Slowly allow the door to wind back into the
housing. (Fig. 1A)
3. Lift the Bracket Assemblies with the Door
and Idler Roller out of the metal housing. (Fig.
3A) Then remove the Bracket Assemblies.
(Fig. 3B)
4. Evaluate the Spring
Hubs to see if they have
been damaged. If they
have been damaged,
please follow the
remaining steps. If no
damage exists, proceed
to step 6. (Fig. 4A)
5. Unroll door on a soft surface (carpet or
cardboard) so damage to the door front does
not occur. Remove spring hubs and replace
them on the opposite end. The damaged
spring hub end should now be inside the
support rod. (Fig. 5A)
