Tension adjustment of the door spring
The door springs are set at the factory to the
proper tension for the outer door.
If aesthetic wooden panel are installed, you
will have to adjust the door spring tension.
Rotate the adjusting screw to drive the adjustor
to strain or relax the steel cable(see figure 5).
Door spring tension is correct when the door
remains horizontal in the fully opened position，
yet rises to a close with the slight lift of a finger.
