The Projectionist's Part in Maintenance and Servicing

It is the duty of the projectionist to see that all projection equipment is kept in condition to give excellent service dependably and efficiently. 1t is impossible to accomplish these results by depending upon memory alone. The projectionist must establish and keep written records of all necessary maintenance data. He must follow a written schedule in making inspections and in doing maintenance work. He must establish a reliable system for checking and ordering supplies and spare parts at regular intervals. — The projectionist should do as much of actual service work as his knowledge, ability, tools, and available test equipment will permit. At least nine-tenths of trouble shooting should be done before any trouble exists. He should obtain detailed drawings of internal and installation wiring of all electrical equipment, besides identifying the points at which tests may be made. He should prepare a written outline of all tests that could be made if various troubles existed. Then he should actually make all possible tests in advance, wherever possible, without causing damage, by deliberately creating the trouble and then correcting it. He should immediately record the exact results of each test in the written outline. In this way, simple tests may serve as well as or better than elaborate ones. — The professional service engineer with special test equipment is a necessity to the finer and more difficult parts of modern servicing, but the projectionist who makes the best of what resources he has can also do a very valuable part of the job.
