WARNING - Garage door springs,
cables, brackets, and other hardware attached to the springs are under
very high tension and, if handled improperly, can cause serious injury.
Only a qualified professional or a mechanically experienced person
should adjust them, but only by carefully following the manufacturer's
instructions.
