Oiling a Press.
Excessive lubrication is wasteful, unclean, and hurtful to a press. A small quantity of oil should be used at a time, as a large amount will overrun on the press, and hold the dust and grit caused by sweeping the floor; these, working into the journals, will wear the press more than use. The best oil should be used, whether sperm, lard, or coal. Kerosene may be used to clean the ways of a press when they have become gummed by the use of improper oil. Presses should always be kept scrupulously clean.
