MANAGERS AND PROJECTIONISTS 735 OIL. — The two main bearings have oil holes held normally by a spring supported steel ball. To oil, press the balls down with snout of oil can and inject one or two drops of oil. Other bearings have plain, open oil holes. CAUTION — If you have an old style take-up which has a fibre disc, then do not get oil on the friction discs. Should you do so, dip a cloth in gasoline and wash disc, X-16, plate* 9, and draw it between the faces of the other discs until all oil is removed. Oil on discs will cause slippage. Keep them clean. ON THE OTHER HAND, if you have the later type which uses a leather disc, X-16, it, the leather disc, must be oiled before using. Never use this disc in a dry condition. Place a few drops of machine oil on it occasionally, so that it is kept soft and pliable, instead of hard and dry. CAUTION. — In Fig. 270 you will observe a hole in which is the end of a shaft. Under the hole is a wing nut. The shaft protrudes from the projector frame casting, in which there is a hole to receive it Be sure the shaft is in place in the frame casting, and that it is in the hole in the controller casting and clamped by the wing nut, else the control will not set right or be properly supported.
