This document contains the operating procedures for the Hall A ``base equipment''. The operating procedures are intended to provide shift personnel with the information they need to understand, at least at a rudimentary level, the function of the various subsystems in the end-station. It should also aid in determining if the equipment is performing properly and provide instructions for what to do in the case of malfunctions. This document is not intended to be a comprehensive reference but is rather a guide for the use of on shift personnel. When appropriate, other references are indicated for the user who requires more information.
It is assumed that the reader of this document has been through all the required Jefferson Lab safety training. Hence, the material covered in those courses is for the most part not repeated here. End-station specific safety items are covered in ``The Experiment Safety Assessment Document for the Hall A Base Equipment'' which is required reading for all shift personnel. This document also contains some safety information when deemed appropriate.
