Crawford Cdm9 950 Installation Manual Top

The top lip hinge is frozen or the return springs are missing. Solution: Remove the lip hinge pin (top access only). Clean with penetrating oil. The manual specifies a 0.010" to 0.020" gap between the lip hinge and the deck edge.

If the operator requires severe repairs or the motor protector frequently trips, manufacturers recommend replacing the complete operator with a modern unit like the ASSA ABLOY OH1042P , as older CDM9 models may not meet current safety "state of the art" regulations. crawford cdm9 950 installation manual top
