If the header bracket is not rigidly fastened to a structural support on the header wall or ceiling, the safety reverse system may not work properly (see page 30). The door might not reverse when required, and could cause serious injury or death.

The garage door springs, cables, pulleys, brackets and their hardware are under extreme

tension. Do not attempt to loosen, move or adjust them yourself. Serious personal injury or death could result. Call for professional garage door service.
