Place a large pipe wrench in position on the door axle as shown and slightly loosen both axle saddle castings. Pull down on the wrench for more spring tension and let up on the wrench for less spring tension.
As saddle castings are
WARNING loosened, hold wrench securely. Springs are very strong and can
cause serious injury if not controlled properly.
Tighten both axle saddle castings per Step #6 while holding the pipe wrench firmly to maintain desired adjustment. Let off the pipe wrench tension only after the nuts on both axle saddle castings are tightened back to 40
WARNING
When removing pipe wrench from axle, slowly reduce applied tension until wrench is free from axle. This will help avoid serious injury in event that saddle castings have not been tightened sufficiently.
Test the door as in Step #9 above. Repeat the above procedure if further adjustments are required. Once all adjustments have been made and the door is operating properly, recheck all fasteners and bolted connections to ensure that they are in place and properly tightened. Tighten all set screws in the components installed in step #4.
STEP 11 INSTALLATION OF TOP DRAFT STOP
Close the door and secure it in the down position. Use a pencil to mark the door panel corrugation that is parallel with the bottom of the header/lintel from the outside of the opening. If this corrugation protrudes below the header, mark the one just above. Open the door until the marked corrugation is accessible. Stretch the top draft stop across the door and attach it to the curtain on the marked corrugation with the #8 x ½”
NOTE:
Top Draft Stop may not seal on header if not installed on a corrugation as shown.
