FOREWORD
It is the intent of this manual to give the reader certain key points of information critical to the proper
installation of the door operator. It is not intended to give comprehensive installation procedures nor does
it cover the installation of door headers, tracks, hangers, etc.
It is hoped that the procedures presented in this manual will reduce the installation and adjustment time
and result in a smooth, long lasting door operation.
When properly installed, G.A.L. operators will give many years of trouble free service.
